How to Put Sound into Your Car

Many people like to listen to songs while driving their cars. However, the speakers which are installed within a car I usually fairly poor. They are hidden behind the dashboard and the acoustics often suffers from vibrations which are caused by the plastic dashboard.

Also, the standard equipment usually doesn’t have a dedicated amplifier and instead relies on an amplifier which is built into the car stereo. Such an amplifier typically does not offer more than 10 W of power. However, given that there is significant noise while driving the car, you will not be able to drive you speakers very loud and thus the sound quality is going to suffer.

However, even though I would recommend blasting your car with music while driving for safety reasons, it still makes sense to upgrade the sound equipment. The upgrade starts with replacing the speakers. When replacing the speakers, you should remove the old speakers and see whether the opening is suitable for housing and new set of speakers. However, make sure that you insert cushioning material which is going to avoid the sound from entering the interior of the dashboard and other enclosures. Having sufficient cushioning inserted will usually be enough to prevent vibrations. Also, the sound is not supposed to travel within the dashboard because it can cause an acoustical short-circuit with the other speaker.

Also, make sure that the speaker is fastened into place such that it cannot vibrate or shake loose. Keep in mind that there will be significant force exerted on to the speaker due to vibrations while driving. Also, make sure that the seal between the rim of the speaker and the outside of your dashboard opening or door opening is sealed properly. This is to avoid sound from entering in between the rim of the speaker and the surface.

Keep in mind though to run the speaker wires before you insert all of the cushioning. It is very difficult to run speaker wires afterwards. You may be able to use the existing wiring which was already installed by the Manufacturer but you want to inspect the gauge of the wire. If the wiring is too thin then it makes sense to replace it completely.

Another component that is with replacing is the amplifier. I would always recommend using a dedicated car amplifier. This amplifier should be connected with the chassis of your car by using some solid bolts. It also makes sense to insert a rubber gasket in order to minimize vibrations of the amplifier. The amplifier should be able to operate with a voltage of 10 V or more. This is to make sure the amplifier also works when other parts of your car a drawing current from your battery which is going to lower the battery voltage.
