I am in the process of upgrading my system in a Chevy Tahoe to an SQ/SQL system and I need some sub advice. I have already purchased my frontend equipment and I will driving Morel components (tweeters, 4" mid's & 9" midbass) with a TRU Technology 4.100 and a TRU 2.200, with a Fosgate/Denon HU. I have also purchased a TRU Tech M-1 Hammer (4 Ohm: 600W x 1;2 Ohm: 1000W x 1; and 1 Ohm: 1500W x 1) to power my sub(s). I currently have 2x 12" Alumapro Alchemy's in a sealed custom box, and I love the SQ of them but I sometimes wish they went much deeper and louder. Therefore, I was thinking of upgrading to either 2x 12" Re HC's or 1x15" XXX. I was actually thinking of going 2x12" XXX, but I don't think 1 Hammer would be enough power to drive them sufficiently. Therefore, could someone please give me some advice on the following:
--Has anyone used a 15" sub in a SQ/SQL install? How did it perform? Do you think a 15" XXX would blend well with my frontend components, or do you think it wouldn't be tight enough or fast enough? Will 1x15" XXX hit hard enough in a large vehicle like my Tahoe?
--Do you think I would be better off using 2x12" HC's instead? How about 2 XXX's, do I have enough power?
--I would like to do a sealed enclosure, is this advisable for this setup? Will a ported box tuned low sound musical enough?
Sorry about all the questions, I am fairly new to car audio. Also, I have already invested quite a bit already and I would like to do it right. Any advice would be greatly appreciated.
