Let’s move on to the next step of working on your car’s sound system. Subwoofer (or bass) speakers are a car audio component that can greatly improve the sound quality and acoustic experience. Inadequate equipment can get in the way of unlocking the potential of your sound system. Even if the other parts are top of the line. See how to prepare and get started with bass box installation.
As with tweeters or midrange speakers, it’s crucial to follow the rules to get the full effect. The fundamental issue is to choose a bass box proportional to the size of the car and available space. Due to the fact that in this article we will focus only on sedans, we have unlimited room for maneuver
Sedan is a body type that works very well with bass boxes. In this case, you may be tempted to have the freedom to choose where to place the box. It will not be a surprise if I say that we distinguish only a few places suitable for this. These include – a firm favorite – the trunk, as well as the space under the rear or front seats. This is mainly due to the fact that, due to their use and functionality, woofers require proportional stabilization. Only in such conditions you will be able to get the full power out of them.
Audiophiles usually choose a cargo area because of the available space, which does not strain the comfort of passengers and driver. What is more, woofers will not be exposed to mechanical damage or dirt resulting from the operation of four-wheelers, which can damage the sensitive membranes of speakers.
At this point it is worth reminding that in order to work optimally speakers need adequate space both in front of and behind the diaphragm. This is particularly important in the case of woofers
Rear and front seats
In turn, this arrangement translates into better audibility. Low tones coming out of the trunk can cause volume loss, which will have to be made up by increasing the power of the bass box. Because of its direct location relative to the listeners, the sound is better and more evenly distributed
For the installation, we will need, among other things – a soldering iron and a crimping tool. When it comes to the installation kit, it is always a good idea to have at hand the power cord (preferably several meters long), fuses, or heat shrink sleeves. The rule of thumb is that we start installation from pulling the power. Because of the power consumption of bass boxes, we connect them directly to the battery. We throw the fuse as close to the power source as possible and we can pull the wire to the inside of the vehicle, using the factory holes.
The next step begins by pulling out the radio to access the panel. There you’ll find an input labeled subwoofer, which you’ll connect your bass box to. Next, you’ll need to connect the amplifier control cable – in the ISO harness, locate the wire where voltage appears when the radio starts up, and connect it to the control cable. Pull the cables under the dashboard and you can move to the next step
Route the wiring to the trunk. To do this neatly and safely, remove the upholstery pieces standing in the way. However, the best solution will be to use the sub-threshold space
Once you’ve run the wires to the trunk, you can grab a soldering iron. You’ll find the appropriate markings on the bass box housing to help you avoid any possible confusion. Plug in the signal wires, power, ground and you’re done. Now you only need to connect the amplifier control cable to the “REM” connector
To improve the aesthetics, it is worth to look into the finishing of the installation, which I have discussed in detail in a twin article!
