I just got a 99 tahoe, have a hifonics 1600watt amp.. Im not sure if I should get a single 15" or 2 12s.. Ive been looking at a single RL-P 15" or like 2 12" Arsenals or Type Rs... Both set ups will be ported with pretty much unlimited box size... Which set up will get louder? Will the 15 suffer with sq over the 12s? If anyone has a 15" RL-P some feedback would be great..Also will the 1600watts be to much for the 15 rlp?
