Ok spring is here so the Fiberglassing is about to start. My question is, where should I install my sub? I have a second Gen Stereo Integrity D2 12" that will be powered by a US Amps 300x for 900 Watts X 1 rms. It is going in the trunk of a 1991 Geo Prizm. It will probably play 60-80 hz down as I will have a 8" midbass in the front doors to pick up the higher end bass. Since I am building a fiberglass enclosure that only need 1.5 cu ft sealed, placement can be anywhere. What box placement do you think would give me the best sound in the car?
