Damping is simply reducing the amount of noise that is coming from inside your car that results from the vibration of the car from its motion. The idea behind this theory is that the less sound that is emitting from the inside of your car, the louder your car stereo will sound.

In order to effectively do this, insulation material should be added to the panels of your car. This will cause your car to vibrate less and therefore increase the amount of sound your stereo emits. When adding insulation, focus on your doors, engine, floor, and boot.

Use a Subwoofer

Best SPL Subwoofers

Subwoofers are a great way to get a similar amplification of sound for your stereo system without spending as much as an amplifier costs. The great part is that these can be used alone or in conjunction with an amplifier, so if your budget later allows, you can always add an amp later on.

Subwoofers allow for additional sound to come out of your stereo system. Make sure to place it in a part of your car that is not likely to vibrate, such as a corner. You then adjust the phase of the subwoofer and ensure it is in phase with the rest of the system. If this is not done properly your car speakers will be competing for sound with the subwoofer, so you may want to have this professionally installed.

Ensure the Music You Are Playing is of a High Quality

Unsurprisingly, the quality of the music you are playing has a direct correlation to the quality of the sound you hear through your speaker system.

Therefore, if you are listening to music that requires you to compress a file, it is a good idea to not compress too much. In general, the larger the size of the file, the higher quality the music will be.
