What's this going in?.............You need to consider that as a part of your decision and how much power are you planning on running?

hmmm, yeah that tuning does sound good.
but Double 07, grand prix's have VERY shallow trunks. i think OP would be better with sub back port back, or port front sub front if hes going for a blow through.
my buddy has one of these cars. depending on how he does the box, if its taller id do faceing seats, if shallower, go facing trunk with port.

Yeah if your height restricts you....You may have to angle the face a little to allow room for the 15"......

i might have to angle it a little but i think i want it going to face the rear i have about 20 inches in height in my 08 grand prix, luckely the trunk is held up by hydrolics outside the trunk
