Im getting quite abit of rattling mainly from the boot door, and was advised that Sound deadening would help, plus i need to do the doors, but have been told a 12 inch square behing the speaker does the job well enough, so there is no need to do the whole door.
With the boot Im only putting one sub in there at the mo, but am thinking of sticking two in there, was doing the sound deadening to help more when I put the second one in there...
Any suggestions on good stuff, and where to get it??? How much do you reckon Ill need???
