Ok guys, so heres the deal. I've been without a system for quit some time now, so it's time for a new build. So I need a little help as to what subs to run, cuz there's a ton of em out there these days and most of what I'm interested in just isn't sold anywhere near me, so nobody knows anything about em. With proper electrical, hu, comps, deadener, and amps all taken care of, I'm now stuck as to which subs to use. I've got 2 SS DTR1.1700's to run at 1ohm a piece, so that should give me a clean 1500+. Keep in mind I'm workin with a Grand Am trunk, so I really only have about 6 cubes total for space, but even that is really pushin it! So heres what I've kinda narrowed it down to: 2 RE MX12D2's ported, 2 RE MX15D2's sealed, 2 IA Death Penalty 12's ported, 2 IA Death Penalty 15's sealed, 2 SSA XCON 12D2's ported, or 2 SSA XCON 15D2's sealed. I know that some of you may say that this is either a good line up or wtf am I thinkin. I only know as much about these as I have read online, etc. I just have read and seen good stuff about all of them but haven't yet asked anybody on here what they truly think though. Please let me know what you guys have to say, good or bad, or tell me if you think that there is somethin better out there, I would love to cut the cost on the subs, but I don't think I will find anything worthy for much less. Oh, btw, I'm lookin for the best of both worlds, spl mostly, that's capable of good responsive sq.
