I'm looking to build a mid-level system. Something simple. I'm driving a 02 Accord V6 now and the trunk is huge so I was looking at the following components: two 12" JBL GTO subwoovers one amp, Alpine MRV-F340 or Alpine MRV-F450 Figured I would buy the subs at Best Buy because of the warranty for $80 that way if I blow anything I can go back and have a "free" replacement. Going to be hooked up to my stock deck, possibly the Panasonic DVD/LCD deck combo. Stock speakers. I'll be getting a new car in July, probably a Z4 so i'm hoping this system can also fit in it. Should I go with one ten? Just looking for more bass in my music. Not looking for attention in parking lot meets.
