I have the ZX1500.1 on a 15" L7 and 2 ZX200.2 push the mids/highs. The ZX1500 is a great every day amp. I've add a 2nd battery and a cap and my volts never drops below 11.9 at full volume. If you can i would advices you to get a 1500 on two 12" L7. You will be very happy with the setup. When i get some more money i'm going to add another 1500 and change my sub to a solo-x D2 AND HAVE 1 ZX1500 ON EACH VOICE COIL AND ADD A 250 AMP ALT
