That is, connecting a subwoofer in a car stereo without an amplifier. But you might be thinking about whether it is possible or not?

Yes, it is absolutely possible. However, to know details about this, let’s recognize some basics about why the amplifier is used with the subwoofer or is it compulsory to have an amplifier? Basically, an amplifier is used to provide more wattage of power to the subwoofer to produce deep bass.

Therefore, if you want deep thumping bass, definitely you need an amplifier. But you can also enjoy hip top, decent tunes without even using an amp.

Thus, the installation and connection are not at all complex, and truly it’s a very easy process. You need to do some wiring, subwoofer replacement, and some small mechanism. So, keep reading this article, and we assure you will be able to connect a subwoofer in your car without an amp.

Let’s start with the small mechanism.

  • You can use extra battery rather than factory stock to induce more power to the car.
  • By wiring rear speaker output as a subwoofer output, you will not get a shattering bass, but it will add extra frequency to your sound system.
  • You can also make a plan to use the subwoofer as a boat anchor and a doorstop in the floor or the door panel.
  • Or you can focus on the head unit. Some head unit has inbuilt power to provide distortion-free sound, and by adding a high pass crossover with the head unit, you can sort out the problem.
  • Apart from this, you can also work with preamp output of the head unit if it has. As because this output bypasses the internal inbuilt amplifier and sends a clear mind-blowing signal to the external amp.

These are a small technique you can have a preference. Now, let’s check out the detail process of wiring and connectivity. Out of this 5 mechanism, we will show you how to connect a subwoofer in a car without using an amplifier and by connecting rear panels.

  • Disconnect the car electrical system or battery completely.
  • Remove the fuse and connect the subwoofer with the main power supply to start with the installation process.
  • Disconnect the speaker from in-built car speaker by doing mounting dock and gaining access on the rear panel of the car stereo by using wiring.
  • After that, take out the stereo wiring and reconnect it again by using an adapter. This adapter provides power outlets to the single cable and mounts the sub in a preferable location.
  • Now you have to set the sub to the rear panel of the car such as behind the seat, under the trunk or even cargo area. It is to note that, placement is very important here as you will do a crossover connection between the sub and car stereo to ensure the correct wiring.
  • On after that, turn on the stereo from the stereo dock (rear panels stereo that runs cables from the speaker and touches cars floor and door panels) and check whether the sound is coming automatically and uniformly from all the location.
  • Hereafter, it will definitely come if the wiring is ok. For extra safety, conceal the beneath wiring wit with carpeting.

These are all simple steps of how can you fix a subwoofer without using a costly amplifier. Conversely, if you want to use an amp to get powerful sound, then we advise you to buy Active subwoofer (It has inbuilt amplifier inside the cone) instead of passive subwoofers (you have to connect an amplifier externally).

Active subwoofers are also known as powered subwoofers. Now about the handling of powered subwoofer you must select “under-powering” subwoofer and avoid “over-powering” one for not to cause any harm to your device. Because over power can burn your subwoofer. But the problem of using powered subwoofer is it is not long-lasting, and the magnet gets damage easily.

So, now you came to know that using an additional amplifier with the subwoofer are depends on your choice and preference. You can effortlessly connect a subwoofer in a car without an amp and use it for a long time.
