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! 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 ??
