So basically I am trying to figure out which subwoofers would be best for me. Background info: Vehicle: 2000 suburban (space is really no issue for me) Amps: 2 planet audio ap1000d's (rated for 650 but i believe put out well over 800 watts) Plans: currently im running 4 12'' cvrs and im ready to upgrade so i want to run 2 18's , I plan to get dual 2 ohmn coils so i can wire at 1ohmn with one sub per amp, this will be a daily pounder, and i will be pushing everything hard, I have the big 3 and a 220 amp iraggi alt, i have the best knu koncepts 0ga wire, and all i need to beef up my electrical is a second battery. I am choosing from Fi subs and my gut is telling me that the Fi Bl is the one for me, so my question is to you guys which sub is best for me? the bl? the q? or the ssd? also as for budget i would like to keep it under 400 per sub
