Customer Testimonial

When searching for Fosgate subs Sonic Electronix had the best price and the shipping was fast. The speakers were packed well to ensure no damage would be caused during shipping. I will definitely use them for my next electronics purchase.

This little amp rocks, I have really tested this amp to the limit and it still does the same thing it did when I bought it. I use it a lot for all my out-door fun in rain or shine..

Rating is 260 watts. Probably putting out about 150. My intent was to put this in my boat to power two coaxial speakers but it would not power them. Had to go with a bigger amp.
