ok so i love my current setup but i know im getting robbed with the non folding rear seats in the lumina, anything i can do besides getting rid of my 6x9s? theres like a 1/2" thick peice of insulation between my rear seat and trunk which i was thinking about removing but not sure if it will do anything
the setup

 

OMG i just flashed back to my old subs lol

 

dont just take out the 6x9's. cut a big hole in the rear deck all together. just dont cut the carpet thats covering it.
