Not all audiobahn stuff is crap, i have 4 audiobahn 1200q's in my mazdaspeed with 2 zr360 amps, and its loud enough it sounds like its gonna blow the trunk completely off the car. To make them fit it was almost a must to build a custom sub zero floor which faced the subs straight up, i wish i could have faced them towards the trunk but i don't think our cars were made for 4 12's anyways. I've used an audiobahn amp before and they arn't that bad. I bet you will be happy with what you have. Good luck.
