[FOSGATE JOE 10+ year member]

Ok i'm going to buy these subs jbl power p1022. 3 of them.My max space is 6cuft.Jbl says for a 4th order it needs to be sealed 0.75/ported 1.25 for each sub.Which i just did the math and it is 6cuft!//content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif for 3 subsSo i guess now i should go with 3 or 2 subs. And if i do go with 2 sub can i make it hit harder with 2. In a big box or just go with 3 sub what jbl gives me data wise?? 3 or 2 ??//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

.75sealed playing into 1.25ported...if the ported area is 1.25cubes after port displacement u looking at over 2 cubes external for 1 10...with 3 10's that 2.25cubes into 3.75 cubes ported...and thats all internal air space after port and sub displacement...so u looking at well over 7 cubes external for this box

so i would do just 2 subs and talk to jbl about an optimum bandpass for 2
