    My teenage son bought the Best Buy Kenwood sub package which included this amp and two 12” Kenwood subs. He used his Christmas money and was so disappointed in the amplifier. Installed everything by the book, even soldering all the connections and wrapping in electrical tape. The first amp lasted 3 days. Worked fine and then no power or blown fuses. The second one lasted 1 day, same thing no power or blown fuses. The 3rd one last about 3 weeks and just started blowing the 30 amp fuses immediately. We bought the 4-year extended warranty from Best Buy which is a joke because it is one use and then you lose your money. We sent the 3rd one back through the Geek Squad and they quickly said just get a new one and poof, the warranty money was gone. Should have just returned it to Best Buy. When we did get the new amp, we found it was the blown amp we took back and told them it was blown, they simply put it back on the shelf, so we had to go back again. Kenwood said these are a new product and from the reviews you can see this is a common issue. Kenwood’s customer service was hit or miss like anywhere, 1 great rep, 1 nice but not knowledgeable and one lady who must have been watching 8 kids because she wanted nothing to do with me except get me off the phone. I have to say the package deal was a great price and the 12” Kenwood subs are awesome and still working. (Knocking on wood). At the advice of a Best Buy employee, we bought the Alpine S-A60M but had to pay a lot more for it. It rocks and works as should. The quality connections were worth the extra costs alone. Sounds better too, tighter bass for sure.

    Good system but I bought as a kit and subwoofers put out more than amp therefore would not purchase as a kid or a bundle I would buy separately and pay close attention to the specs

    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.

    amplifier purchased as open box in "excellent" condition. It was missing pieces and so far has not worked. Best Buy customer service being anti-customer service and currently giving a hassle to return (because its 2 days past return policy). Return policy should be negated when you deliver products missing pieces and not working. Customer service at best buy has become awful.
