okay okay... kicker recomends 5 different boxes for 3 different responces...
1... Sealed... .88cF Per sub.... COMPACT *(MINIMUM SIZE ENCLOSURE*... @750Watts
2...... Sealed... 2.0cF Per Sub... Maximum Size Enclosure *Sound Quality**** @ 750 Watts
3........ Ported... 1.75cF Per Sub... 2.5 x 13.25” port, 22.5” long ..... Compact Box.750Watts
4........ Ported... 2.5cF Per Sub... 2.5 x 13.25” port, 16.5” long ... Street Bass/SQ...750Watts
5....... Ported.... 3.25cF Per Sub.. 3 x 13.25” port, 14.5” long... SPL/DEEP AS F&&K.750Watts
Point being, kickers L7 12 will do whatever you wish... if you like smooth bass, or loud as hell bass... they give you exact specs for all of it...
and I'm sorry to say but I agree with Sentra95... stupid people blow subs... you can't play a single sub with stupid amount of power... with it being a SOLOx, Old school Stroker, or whatever.. if it's tuned correctly with the amplifier @ the correct settings, you will not blow subs... I have had my OLD school Pioneer 10's since I was 16 and have yet to blow them... that's been 8 years now...
