I have this amp running on 2 12’s wired @ 4 ohm. Strong amp no issues runs very cool does everything they say it will do. I also have the 1200w 4 channel running my mid and highs with 0 gauge wire feeding a 20 farad cap then distibuting power to both of these beasts through 4 gauge. With them running wide open I only get voltage as low as 13.7v with no extra battery and just my stock charging system. these things are not power hogs but produce great clean sound. I recommend this amp and any of the other planet audio equipment to anyone. I have been putting sound systems together for close to 20 years. Great buy for the cost. You will definitely not be disappointed!!!!
