Great amp

   Aaron Henson From Reno, NV
This little guy Thumps! I did a complete overhaul of my system in my Silverado, and this amp is so powerful, it destroyed my Kicker door speakers! The installer who wired my truck told me that this little amp was more of a competition amp and that I needed at least 100w rms speakers. Also, be careful. Amps rarely ever have the exact rms output the box/add states. My amp came tested at 357w rms! I bought 110w rms door speakers, and I couldn't be more happier!

This amp rocks. It is big bang in a small package.
