Time to build

from ur wording here i wouldnt consider this SQ.. i assume u just want the bass to sound better.. have more of a impact... i would suggest around 5-5.5 cubes tuned to around 34hz and u would need to make some sort of manifold to direct the all the sound to come through a shoot in the rear deck.. with it loading off the rear windshield it will bring the overall tuning down .. and u should get a well loaded sounding bass

The back window is straight up/down,

I want to hit the LOW NOTES, loud and low,

my trunk springs are in the way, so I need to make something to open the trunk.
