Customers admire the CX 400W Class D Digital Mono Amplifier for its power and sound quality. The amplifier is also appreciated for its compact size and ease of use, making it a convenient option for many users. The bass performance and reasonable price point are additional benefits that customers find appealing. However, a few customers have noted that the amplifier can generate some heat.

    My car stereo stop working. I have been driving weeks with no music. And yes it’s under warranty. So on my radio display all it says is Amp Error. My whole car stereo system has not been working since I bought this item from Best Buy.

    I bought this Amp and installed it in my vehicle, It did not work at all from day 1. I will not waste my time on buying this product again. Not satisfied and of course the warranty ran out 2 months ago, so now I am stuck with a non working piece of garbage.

    Very good amp but if you are hooking up to a factory radio make sure you spend the extra money for the line converter the 15 dollar one can not handle it
