The LC-6.1200 is one of the best, most versatile amplifiers you will find. Clean, very powerful (1500 watts RMS) and loaded with features. A built in DSP gives us endless control & options. This can run a number of setups... a 3 way active front stage, an active front stage and a sub, an active front stage and rears, fronts and 2 subs.... This amplifier can seamlessly tie into any factory audio system, as it has a LC7i built in! Oh and it also has a 5 year warranty? Awesome
