I want to run 2 12" subs and keep my stock spare. As well as have a little trunk space. I bought 2 12" 900W Fusion PowerPlant subs dual voice coil and i can run 2 or 4 ohm.What ever that means.. I also bought 2 sealed boxes with approx 1.25 cuft of air space. My question is will this work? Right now I'm also looking for a good amp that will power these 12s... any suggestions? All the local stereo shops are giving me mixed info. I think they just want to sell me anything that may work. I want WILL work. Ive read a few posts and it looks like i may want to cut a hole in my rear deck for sound purposes as well as take out the material behind the back seat, and from what i read i will want to face the speakers twords the back of the car. Any info will be greatly appreciated. The front speakers are boston Acoustic and are working fine with a 200w kenwood powering them as well as the polk audio 6x9s. The stereo is great but i need more base.
