This had to be the worst amp ever. I bought my amp 6 months ago in ny, but only installed it last week. After playing this amp for five minutes it blew up. When I phone the company I was informed that it was out of warranty. The funny thing was that they was unwilling to even post the parts to me because i lived in trinidad. I was informed by the manufacturer to ship this product back to ny and then pay 85us to have it repaired. I just decided to source the parts locally and repair it. I am totally disappointed with mtx because i have a phoenix gold 5 channel more than 4 years now and no problems.

I have 5 channel amps before this one is nice and not big it can fit almost anywhere. It looks great and has good power to run a subwoofer off of it. If you are looking for crisp clear sound buy this amp.

Customer Testimonial

I thank you so much, I ordered these speakers for my husband 3 days before X-mas and received them 2 days later. They are great he loves them. It was a better deal than B*** B**, and better customer service. Will definitely purchase again.
