Hey guys, I just registered on the forum, it looks cool. I frequent some other car audio forums and I heard this place was cool so I decided to check it out. Anyways, on to the question:

I currently run a DD 9515 on an American Bass 3000 watt amp. I'm thinking of switching to a more SQ based system (the DD sounds great but they are not the best at hitting the lows below 40 hz or so).

So, I'm looking into maybe 2 Fi Q 15"s, but I want the new system to at least be as loud as my DD while gaining a little in the SQ department. The Qs would be run off the same amp getting 1500 each, and I would get their upgrade for power handling (forget what it's called).

So whats your opinion, will the Qs have better low end, and will 2 of them be as loud as one 9515?

I would think so. If not louder.

I love my 12 Q. Its been great to be and I love teh way it sounds.

2 15" subs should be able to have a great deal of output, and there are plenty of dual 15" Q installs.

do you have the room for a pair of 15s? box is going to detemine alot, and if you don't have the room......

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

That's what I thought, that having 2x the cone area would make up for them being more SQ based subs.

Yes I will just barely be able to fit them, giving them 3 cubes each.
