Difference active – passive subwoofer

adminonJune 18, 2022February 11, 2022Leave a Comment

In many forums, articles and car subwoofer test is of course spoken of active and passive subwoofer. But especially as a beginner you can do nothing with the term, but it is so simple. The small difference is that in an active subwoofer the power amplifier is already integrated in the subwoofer. In passive subwoofer, the power amplifier and the subwoofer are separate from each other. Each system has its advantages and disadvantages in installation and purchase. And this is what we are going to tell you about.

The classic: passive subwoofer

The passive subwoofer is a classic, because the original form was already built this way. The subwoofer itself has only one diaphragm and does not generate any power. This power comes from the amplifier. Therefore, the power amplifier needs both power and the input signal from the car radio. In the picture the wiring diagram is very nice to see.

The difference with the active subwoofer is:

It has more power and plays a stronger bass
But consumes more power
It is mainly installed in the trunk
Is larger than an active subwoofer

The compact: active subwoofer

The active sub combines the power amplifier and the subwoofer and is therefore more compact. For this reason, there are smaller designs than the passive sub and it fits under the passenger seat or in the spare tire recess. But there are also larger models that want to make the passive subwoofer a competition. In the picture you can see the wiring diagram (the subwoofer used is again the JBL GT5-2402BR). It is actually a passive subwoofer, but here it is only for illustration). Here you can clearly see the difference active passive subwoofer, because from two components only one is left.

The differences are again clearly visible here:

Quick installation
Easy wiring
Less power consumption,
Since the power is less (the bass is weaker)
Gives several options for placement

The differences in installation

In addition to the characteristics, there are also some differences in the installation. With passive subwoofers, the power amplifier and the subwoofer must be wired separately. So first the power amplifier gets the power supply, cinch cable and remote cable and only then the subwoofer gets a cabling. This is costly and since there are two components, they need more space and each must be fixed separately. The power and the impedance must be matched. You can also bridge the connection in this case to get even more power out of your sub, but there are some rules you have to keep in mind. You can adjust the sound on the power amplifier. The screws are usually finer and better than an active sub.

In contrast, the active subwoofer is much easier to install. It is connected directly with power cable, cinch cable and remote cable. No other connection is necessary. Unfortunately, the settings can only be changed on the sub and are not of such high quality. Also a bridging is not possible, but you save the tuning of the two components to each other.

Also when buying active – passive subwoofer there are differences

Last but not least, there are also differences in the purchase. Because with a passive subwoofer you have to combine all the accessories yourself, unless you buy a subwoofer set. Of course, this gives you a lot of room for up and down. You can get much more out of your audio system and do not have to fixate only on 1 manufacturer. However, the assembly is not always easy. In our reviews, we have always listed the appropriate accessories for you to get the best result with minimal effort. Another advantage of passive systems is that you can change the accessories at any time, even at a later date. For example, if the power amp is defective, you can repair it or just replace it. If this happens to you with the active you can throw away the whole subwoofer.

Besides the disadvantage it has an advantage: the subwoofer is supplied with the accessories. There is no powercap (mostly under 500wrms) or power amplifier necessary. the cables, however, are not included with all of them and may have to be ordered separately.

Must dogs in the car be strapped in? How must a dog be secured in the car? Traffic law and the German road traffic regulations (stvo) stipulate that the transport of animals in the car in itself no fines before. However, the load – under this term the pets in the fine table – must be adequately secured, otherwise there are various sanctions, which you can see in the fine table.

transport boxes or baskets
Car seats for dogs
separating grid
Safety belts

It is advisable to look for suitable accessories for transporting animals in specialist shops in good time. It must be adapted to the size of the animal and its nature. A lively dog, for example, may suffer in a dog crate, but the installation of a partition grille separating the rear car seats from the driver’s cabin is enough for him free space, to survive even a longer trip relaxed.

If a long drive if you are planning to take your dog with you in the car, you should plan enough time to test transport boxes and the like in order to be able to to make sure the animal accepts the transport method and tolerates well.

Transporting dogs in the trunk?

If a dog is transported in a car, it must be adequately secured.

If the trunk of the car is large enough, there is usually nothing to stop you from using a transporting a dog in the back of a car. this will not result in a fine, because according to stvo and traffic law this method of transport is permissible. The dog has there a little more space than in the passenger compartment.

However, there are two things you should keep in mind when transporting your dog in a car. On the one hand it is appropriate a protective cover in the trunk to protect the car from dirt and scratch marks. On the other hand, you should consider to use the trunk for to be separated from the front part of the car by a separating grille.

especially if your dog is used to riding in the passenger seat, he might get the idea to, climbing forward during the journey. This involves risks, because on the one hand this maneuver distracts the driver, on the other hand the dog could hurt itself while climbingen. Around the dog safety in the car To maximize the safety of the dog in the car, it is therefore advisable to use a separation barrier. This can also be mounted so that the dog can be transported on the back seats of the car.

Thanks to the transport box, you can take your dog safely in the car

In order to transport a dog safely in the car, a transport box is the best solution.

In order to secure a dog in a car, it is advisable to use an appropriate transport box. This is available in different sizes, so that there is a suitable model for (almost) every dog. You can also choose between different materials. There are both transport boxes made of fabric, metal or plastic.

The transport box for the transport of your dog in the car should be large enough that he can sit and lie in it comfortably. When using it, make sure that your the four-legged friend gets enough air. So the box must not be obstructed.

Smaller transport boxes usually find in the footwell behind the front seats space. Here they cannot slip or shoot forward or to the side in case of an accident. Especially for small dogs, a transport basket in the car is a good idea. From putting the box in the back seat is often not recommended, because in many cases it is not possible to secure them sufficiently with belts is.

Large transport boxes usually fit only in the trunk. Here, too, the correct securing must be ensured. It is recommended that the box with ropes or. straps to secure it, so that they cannot slip in the trunk of the car. For even more safety there is a separation grid, which is attached between the trunk and the back seat.

Compulsory seat belts for dogs?

If a dog is taken in the car without being secured, it can quickly become a danger.

For humans there is a seat belt obligation. But dogs must also be strapped in the car? A dog must not be transported on the front passenger seat without further security. Finally, according to stvo the load is not sufficiently secured. The dog can always be thrown through the driving space; moreover, due to nervousness and restlessness, it can also move on its own and consequently become a safety hazard.

Since the safety belt for humans does not want to fit the dog so right, there are in the trade also safety belts for dogs to buy. So the dog can also be strapped in and is safe in the car. Attention: when you secure your dog in the car, always check the fit of the safety belt. strangulation is very painful!

Straight around smaller dogs to secure the dog in the car, a special car belt for the four-legged friend is often a good idea.

The devices consist of a harness, which the four-legged friend must wear. In addition, the dog must be sit in the back seat.

Transporting cats in the car

Cats in the car are usually restrained by a transport box optimally secured. Unlike the transport of dogs in the car, the body size of cats is less problematic. The box can be placed either on the passenger seat or in the trunk of the car. However, the safest place is in the footwell behind the front seat.

According to the stvo and the regulations specified there concerning load securing, the box with the cat in the car should however be fixed, so that it is not thrown around in the interior even in the event of sudden braking.

FAQ: animals in the car

No, animals must be secured during the journey. Otherwise they may be fined. You can find out how high this can be in this table.

No, but they must be secured, z. B. Through animal safety belts, transport boxes, special car seats or separation grids.

There is no regulation on how to secure animals. The only important thing is that the animals cannot injure themselves during transport and that they do not pose a risk to other people in the vehicle (e.g., the driver). B. In the event of a full braking) represent.

Alternative fuels are one of the biggest hot topics of the moment. Rising gasoline and diesel prices are frustrating consumers and putting the spotlight on powertrains that are above all: cheap.

Z. B. Natural gas cars, which are not only much cheaper to run, but also have a lower fuel consumption

Environmentally friendly,
Tax benefits and
Available as standard from numerous manufacturers.

Some good arguments to turn your back on conventional fuels.

We take a closer look at natural gas cars and compare them with conventional vehicles.

Natural gas increasingly popular as a fuel

Alternative energies are finally socially acceptable, even as a car fuel. And even though autogas-powered vehicles still lead the field in germany, natural gas is becoming increasingly popular as a refueling option.

Natural gas, also known as CNG (compressed natural gas) or LNG (liquefied natural gas), has become much more common in many countries than in Germany. A VW team therefore dared to experiment with a round-the-world trip in a natural gas car and was able to prove that natural gas vehicles are now suitable for everyday use:

There is one main reason why natural gas cars are also becoming increasingly popular in germany:

Natural gas is considered the cheapest fuel!

Although the price looks more expensive than autogas, it is not. LPG is charged in liters, while natural gas is charged by the kilogram. However, the range of a kilo of natural gas is much greater than that of a liter of autogas.

According to the study "the car market up to 2040: what will power the car of tomorrow", the price of natural gas will continue to rise only slowly over the next few decades and will remain permanently below the cost of gasoline or diesel. For an insight into the study in its entirety, visit the website of the mineral oil industry association e.V. (can be found in our related links).

In germany, you currently pay around €1.10 per kilogram of natural gas (as of february 2014). In economically uncertain times, probably the most important reason why more and more consumers are switching to a natural gas car. The german energy agency calculated that 1.1 million natural gas vehicles are expected to be on german roads by 2020:

Accordingly, the number of natural gas filling stations will also increase in the following years. Between 2001 and 2012, the number of filling stations had already more than quadrupled:

The opportunities for drivers with natural gas tanks are therefore increasingly improving. one more reason to choose the low-cost alternative to petrol or diesel. But natural gas vehicles can also score points in comparison with autogas-powered vehicles.

The differences between autogas and natural gas

You should know that natural gas and autogas are completely different fuels (learn more about autogas here). Therefore, you cannot fill up with autogas in a natural gas car and vice versa.

You should therefore think about which system is best for you before you convert or buy. Here is a clear comparison of the two fuels:

Natural gas	autogas
fuel (100 km)	ca. 5 – 6 EUR	ca. 6,40 – 7 EUR
taxes	Mineral oil tax concessions until 2018	Mineral oil tax concessions until 2018
conversion	from approx. 2.500 EUR	from ca. 1.EUR 600
standard models	yes	hardly to be found in germany, import possible
gas stations	ca. 900	ca. 6.500

If you drive a natural gas vehicle, however, it is possible to fill up with biogas, one of the most climate-friendly fuels. How biogas is produced is explained very clearly in the tv program "lowenzahn":

In germany, there are already more than 100 biogas filling stations, and the trend is upward.

How environmentally friendly are natural gas cars?

Natural gas is one of the most environmentally and climate-friendly fuel options. Only electric and hydrogen cars have a better balance sheet, but they have not yet established themselves in the same way.

With a natural gas car, you are therefore currently making the best possible contribution to environmental protection. A natural gas-powered vehicle produces up to

75% less carbon monoxide,
25% less carbon dioxide and
60% less hydrocarbons

As a gasoline engine. This is why all natural gas vehicles receive the green environmental badge.

Save taxes with a natural gas vehicle

To promote sales of natural gas vehicles, motorists can benefit from tax breaks for natural gas cars. energy taxes of 18.3 ct/kg will apply until 2018. By way of comparison, you pay 65.5 ct/l for a gasoline-powered vehicle. As a result, fuel costs for natural gas will remain low in the coming years.

In 2009, an emissions-based vehicle tax also came into force. Vehicles that are to be delivered as of 01.01.registered in 2014, drive tax-free up to CO2 emissions of 95 g/km. For each additional gram 2 EUR will be charged.

Natural gas car drivers have a clear advantage here. This is how the VW eco up produces! As a natural gas vehicle, it emits only 79 g/km and is also considered the most economical natural gas car in the world.

In many regions of germany, you can make additional savings when buying a natural gas car. Many energy providers are offering subsidies of up to 1 euro for the purchase of a new vehicle.000 EUR. Check with your energy supplier for local subsidy offers.

Are natural gas vehicles dangerous?

There is a noticeable lack of safety with regard to new fuels. Here’s how consumers keep asking about the safety of natural gas vehicles. Without reason – as facts prove.

Z.B. Is the risk of ignition in the event of a tank leak much lower than with a gasoline or diesel vehicle, as the

Ignition temperature of natural gas with 650°C relatively high

Located at. By comparison:

Gasoline ignites at 220 – 460°C,
diesel already between 200 and 350.

Therefore, no increased risks are to be expected in the event of an accident.

Even the high pressure of the tank, which is 200 bar, is not a safety risk with natural gas vehicles, as conventional natural gas tanks can withstand a pressure of up to 600 bar.

There are therefore no dangers in operating a natural gas vehicle.

Note: many drivers are unsure whether they are allowed to park their natural gas car in underground garages. This is not a problem! You can park your vehicle in public underground garages without any restrictions.

New purchase or conversion – what’s worthwhile?

Numerous car manufacturers offer their latest models also as natural gas variants. But also a conversion of your car is possible. You should therefore decide individually which option is more economical for you.

In principle, it is worth buying a standard natural gas car, which has. However, if you are not planning to buy a new or used car, a conversion is definitely worthwhile. However, it is a little more complicated and may take up more space in the trunk.

Numerous new cars with natural gas

Today, almost all major car manufacturers produce natural gas vehicles as standard, which are no different from gasoline or diesel models.

Big brands like

Audi,
Citroen,
Fiat,
Ford,
Honda,
Mercedes,
Opel,
Peugeot,
Renault,
Volvo and
VW.

Pray them partly several vehicles with natural gas operation.

The most popular cars include

The opel zafira CNG ecoflex turbo,
The VW passat 1.4 TSI ecofuel
The ford focus C-max
The fiat panda natural power and
The mercedes B-class B 170 NGT blueefficiency.

However, the purchase price of a natural gas car is somewhat higher than that of a gasoline-powered car. You pay about between 1.500 and 3.500 EUR more for a new car. However, the resale value is correspondingly high.

Conversion to natural gas pays off?

Of course, it is also possible to convert a car to natural gas, but this conversion work is only worthwhile if you drive the car for a few years. The conversion, which will cost you between 2.500 and 5.The cost of EUR 000 will pay for itself with an average annual distance of 25 km.000 km after about 3 years.

In addition, you will have to pay for the TuV inspection of the installed gas system. You can therefore assume that you should keep your vehicle for at least another 4 years so that the conversion pays off.

But can any vehicle be converted to natural gas?? No! The conversion is only possible for vehicles with gasoline engine. And here, too, there are small restrictions that make the conversion not possible or not worthwhile for individual vehicle types. Ask a specialist dealer for comprehensive advice on whether converting to natural gas is worthwhile for your vehicle.

If your vehicle can be converted, it is advisable to upgrade to two fuel systems:

gasoline and
Natural gas.

Especially in areas with poor coverage of natural gas filling stations, you have a safe alternative if the natural gas tank is empty.

Note: after a conversion, please remember that the installed natural gas tank must be noted in the vehicle registration document, otherwise you will lose your operating license!

Filling up with natural gas is worthwhile!

If you want to save money and value an environmentally friendly vehicle, a natural gas car is the right choice for you. Because prices will remain low and the number of natural gas vehicles and filling stations will increase.

So if you’re looking for an alternative to gasoline or diesel, get advice from a natural gas systems specialist. Because natural gas is one of the fuels of the future, which will also bring you many advantages! We wish you a safe journey in advance!
