    Very solid amp, got for a great price. It pounds the woofer hard, until it quit working a year later. Right outside the warranty period. I would suggest to get extended warranty through Best Buy for peace of mind.

    RED LED on 100% and the amp won't put out sound after 2months of use. I'm sure if you use it at 75% it will last longer, I used it.

    Hooked it up to a 1200 watt skar 15 inch sub, it worked but it would cut out once cranked up all the way and need to turn off and on my radio to kick back in, 2 days after normal use, it decided to not work anymore. I liked the quality of bass it put out but it didn’t last long.

    Not great. Why would they offer a service plan for a quality product?

    Bought this as a open box item, little less than a hundred bucks. It was connected to a 15" skar sub at 4ohms. Found three mosfets had exploded when I lost bass one morning, and pulled it's cover to inspect. I will stay away from the low end Kenwood/JVC equipment from now on.

    Failed in 10 Months

    I have to give a lower rating because the amp blew within 10 months of having it. I was informed that this amp does not have a safety mechanism that triggers when to much power or a short happens. I am gratfuk for Total Tech!
