    Not what I was hoping for from Kicker product. Lasted a month, bought larger to replace. Nice compact size, was nice when it worked.

    I was not impressed with the overall service provided by the Geek Squad. I had to wait 4 weeks to have my stereo installed and am not happy with the final product. They said that they could replace my old amp behind my back seat - they could not. They called twice to ask me how to do it; I was a bit thrown off then as they were the “professionals” and had already stated this would not be a problem. I suggested that they check out YouTube for assistance. They then told me that they could not find a you tube video. I did a search and found several with out any problems. They did not incorporate my factory microphone or USB with the new stereo but said that they could. I paid to have a harness that incorporates all of the factory provisions with the new stereo. They told me that my factory USB and Mic had broken; I am not sure about the mic but I can still get a power charge off the factory USB. I feel as though these so called Geeks were lazy and didn’t want to make the extra effort needed to do the job right. The microphone and USB they installed, looked like my 16 year old self did the job and my 16 year old self was lazy and cut corners any where he could. They did not walk me through the new stereo process. I had to go back and inquire as to why my USB was not working only to discover that they had added one that was now dangling from the underside of the dashboard on the passenger side. Had I known that waiting 4 weeks would have resulted in this, I would have taken my vehicle somewhere else. I do not recommend their services to anyone.

    This amp worked great for about 4 months and all of a sudden it went to protection mode. called Kicker they are paying for the return to run diagnostics on the amp, have to wait to see what the outcome is.
