I have owned this amp a little over a year and have not had a single issue. I used it to power two rear deck polk 6x9s, front door polk 6.5"s and 1" visonik tweeters on the dash. It was connected to my factory radio via tsunami line output converter. This amp gets really loud and never cut out on me. I like to play to my music loud just about all the time. I recently got an aftermarket radio (no more tsunami LOC) and it just brought the amp to a whole other level because the aftermarket radio is supplying 4v input signal. My amp gain is less than a 1/4 turned up and it still gets super loud. I have a ton of gain to spare on the gain knobs.

I am very pleased with the super affordable amp.

Customer Testimonial

I'd just like to say that you guys at Sonic Electronix are way awesome. I ordered a Sony amp that turned out to be discontinued, but Larsen and Armen were able to figure out a deal that made me a happy customer. Thanks guys, keep up the great work!
