Ok ive used the search and cant find what im lookin for. I am in the market for a 18 FI. I want the Q for its ability to sound good and get low, but I have a Kicker zx1500.1, Kinetik 800 audio control linedriver and a kicker 2 way active cross over. My concern is That 1500 rms on a daily aplication in a close to 6 cube box might not agree with a Q. So if i go the BL route i understand it wont sound as good, but can it get as low. I like the lows that make your steering wheel bounce. Thanks !
