That black sound deadning material that is behind the seat and under carpet ???

[AsphaltAnihil8r]

Does that have any better sound dampining factor over the Dynamate extreme,should I just get rid of it if I am dynamating the interior ,,or should I put it back in except for the rear seat material ,,sub sound comes thru..
Thanks

I got rid of mine altogether for my sound system, it does help the sub sound a little but is useless for sound deadening. Worry about sound deadening the rest of your larger sheetmetal for rattles. This is only my opinion . It wont hurt to leave it in.

Cut out the section between the trunk and cab, leave the rest. Just put the Dynamat down then put it back on. It won't hurt anything, it might just help slightly.
