[QUOTE="paikiah, post: 230166, member: 545724"] well, if you calculate it that way...for SPL, two is almost always ( think ALL the time,r eally) better than one. More airspace moved, more SPL. You've had an L7 before. I'm sure that would've gotten your money's worth too, unless you didn't build the right box for it. Erm, the power HX2's have a certain mounting depth, slightly more than a L7, I think. Be sure you measure your box properly and be double sure that two HX2's will fit. Other than that...hmmm.. one sub is rated at 1000w RMS. you'd need about 1500W or more to get them pumping like they should. As they are dual 2ohms, you'd need amp amp that produces about 1500~2000w RMS @2ohms. (RF bd1500 would be another RF choice, but again, there are other amplifiers that will achieve those numbers, with less $$$) You gotta watch out for the alt. any amp that produces over 1000w would demand a lot of current. I don't know what mustnag's alt is, but most alts that come with the car are not built to accomodate 2000w of audio power. [/QUOTE]
