Can you guys tell me which are the right & perfect subs to go in a dual downfire truck box sealed with .77 cu. ft. per chamber and a 6" mounting depth? What I found were kicker cvt's 4 3/8" mounting depth 400w RMS min. 1.0 cu. ft. sealed, Alpine type S 5" mounting depth 300w RMS min. .8 cu. ft. Look at the new type r 1043d 10's take 600w rms and 1800w peak sound like those might hit harder and deeper than a 12 with less than 600w rms huh? And mounting depth is 5.875" perfect for a 6" depth box.
I normally go with 15s in a car or 4 12s. 10s in a truck are better than no subs at all. Still tho will 2 type r 10s with 1200w ems be louder, deeper than 2 kicker cvt 12s with 800w rms? My cousin said he put a 1500w amp on 2 type r 10s and put a crossover at 50hz and it sounded like 15s to him, said it hit the low notes,I don't think I believe that.
