I've been sick lately, sorry I won't be on much.

Ok as i said ...i got a sub at the back, when i turn the bass up i can hear there is it's not hit hard at the same time there is sound like it hit again the metal...but i dun know where it is.

Sound deadening can be addressed by using one of the three methods, or, a combination of the three.

1. Decoupling = Is to limit the ability of the sound to move from one medium to another. Decoupling will reduce midrange and bass sounds.


2. Deadening = The idea of deadening is to absorb the sound energy that goes through the vehicles fabrique or material(s) it is very effective at reducing low frequencies.


3. Increased mass = Requires more SPL or energy to move the greater weight / mass. but eliminate highs or treble tones.
