There are a lot of different amps on the market with power subwoofers and it’s up to you to decide between them. The options are as limited as your wallet is. These days if you have the money, you can make the amps do exactly what you want them to.
There are mono amps to power a single subwoofer and amps that have every option that you could ever dream of. Daisy chaining amps are one way to get all of the power you want. You can get more bass thump by running a mono amp for each subwoofer.
If you already have the subwoofers, you need to get the right amplifier to power them. When you add subwoofers, you also need to add an external amp to power subwoofers. The best way to choose the amp to power subwoofer is to match it to the subwoofers.
If you are looking for true high performance sound, you need to consider a power subwoofer enclosure design based on the room that you have for them.
Now you need to plan where and how to mount the amp or amps in your car. This is a critical step, especially if you are working with limited space, and you also have an enclosure to install. If you are installing multiple amps, this needs to be planned very carefully.
This where step 3 will help you out. In step 3 you planned where and how you were going to mount your amp or amps to power subwoofer. Now you are going to actually mount the amp in the car. Like any other type of stereo equipment, you need to run the power wire first.
This should be a 16 gauge red wire running to a main power source in the car. Now that you have done that, you need to make sure that the ground is properly connected to the metal body of the car.
This part is usually fairly easy to do. It just requires you to plug in RCA cables to the right ports on the car stereo head unit.
Heat the soldering iron and get your solder and solder the length of speaker wire that you need to reach the power subwoofers and add it to the amp wiring.
Then put a piece of heat shrink tubing on the wire where you soldered the wires together and shrink it down with a lighter, and then plug it in to the power subwoofer enclosure.
