I am currently running a DD 2512, in 2.2 cubes ported. The box was designed by Taylor and I asked him to tune it low for Rap but not sure what we settled on. I am powering it with a MBQ 1500.1 which provides 1500 @ 1ohm. This in a 2000 Lexus GS. I recently upgraded the alternator when the stock one gave out. I've also did the big 3 at the same time.
I've been very happy with this set-up for about 18 months. But, as we all do from time to time, I've gotten upgrade itis. The main thing I would like to upgrade is low frequency response - I seem to be missing drops 40hz and lower. So, in short I would like to bolster output in that area, if I can gain a little output at the same time that would be nice but better lows are the main goal.
I think the DD is about fried so a new sub is needed. I thought going to a 15" and sealing it would be best. I'd rather not give up much more trunk space so sealing might help close the gap on lows and keep the box smallish. But guys, I'm really not sure here. I'm open on budget but not sure what direction I should go. Looking for advice.
