So i was thinking of selling my 21 warden and goin with a new setup. I thought either 2 18s, 4 15s, or 6 12s but im thinkin 4 15s would be cheaper than the 12s and louder than the 2 18s. I have a 2003 trailblazer and i want to wall it at c pillar while keeping my back seats. I currently have a Crescendo bc2k wired to .5 ohm and i want 4 D4s so i can wire to 2 ohms when i get another bc2k. Id like to put 3k rms to all 4 when all set and done. The thing i need help with is deciding which subs would fit me best. I listen to rap/ hip hop mostly but also country and dance music too. I would want the tuning to be around 34hz. I have around $700 to play with but id go more if i absolutely have to. Ive been very interested in the sa15 and oa15 but what other would match up good with those subs? i can think of dc lvl3, ssa dcon(only becus the gcon is more expensive), fi ssd but what else? thanks everyone and if theres anything else i forgot to say please ask!
