I have a 75 impala and was wondering does anybody have any tips on how to get more bass in the cabin im not using any rear speakers so i get more bass threw the rear deck that way but are there any other options, i was thinking about cutting out two more 6/9 holes in the rear deck.

is that a glasshouse?

anyways pull the back seat out, there probably is a layer of 1" thick rubber deadening. Rip that out then put your seatback back on

hmm, in all my old gms i did like you already did, took the rear speakers out and the deadener behind the seat. Maybe changing the way hte woofers fire will help, maybe the box is so big aire cant get around it into the cabin
