well, one 15" is enough for that...im in a ranger extended so the subs are right behind me so its not hard to be loud to me. as far as db's it would be cool to hit at least 135 maybe
is it true that fi's demand more power than the rms?then maybe you should look at two 15" Q's...youll definately be in the 135 range if they are ported with the right amount of power....which is exactly 2k
then again ive never actually heard 135 so i was just guessing.well, one 15" is enough for that...
you can save money from just buying one, and get a higher quality sub then what's listed.
