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?
