[QUOTE="Kybasshead75, post: 8751646, member: 681033"] Keeping in mind that I listen closely to drum cadence that does enter the subwoofer frequency region do you think level fours ported wood have the transient response I enjoy? I've always heard a smaller ported box offers that at the expense of a little on the bottom which is okay with me I think it will still be enough with the cabin gain of an SUV. My other option would be to run those three si SQL 12s which I'm pretty certain would satisfy my musicality requirements. Given that I have 42 w x 17h x 32/35d to work with ( this is crutchfield not my measurements I'm still waiting on a family member to transfer the vehicle as they're finding another one), what would you recommend. ( Honestly I would be happy with the most SPL I can get while still having musicality, I understand you can't have it both ways) already have 40 ah of lithium lto and willing to get another 80 if necessary.
