[QUOTE="bugflipper, post: 7180896, member: 621756"] It's a class b so a little power hungry compared to a class d. Just make sure you have big 3, a good battery and 4 ga power and ground. A second battery really wouldn't hurt to keep the volts up. It is very hard to maintain 14.4 volts, especially with a class b that is power hungry. Overall it is not a bad amp. They are very quick to clip since they are power hungry and drop voltage on a stock vehicle quite a bit more than a lot of class d amps. If it were mine and I planned to stick with the single l7.
