Very good clean constant power.

I originally ordered this amp to drive a Single Infinity Kappa 120.9 however never got to that project. I ended up getting a Silverado crew cab, and using this amp to power 2 Infinity Reference REF1200s the Infinity slim subs with select-able ohms. I was a bit confused it is a mono amp but had 2 positive and 2 negative speaker outputs, however they are not arranged like a typical two channel with a left and right side. Instead it has 2 positive on one side and two negative on the other. I planned to run the subs @ 2 ohms then I saw this mono amp had 2 output spots. So I flipped the subs back to 4 ohms and just hooked it up like a 2 channel. I am very impressed the amp delivers the power to the subs flawlessly, the amp does get very warm but has never gone in to protection. I have put the amp through its paces between bass heavy music with long sustained bass and punchier kick drum bass. I have been using the amp for a month with out any issues. I like the bass controller it comes with turn the amp down when children are riding in the truck. I am satisfied with my purchase and recommend this amp for any who needs roughly 500 strong watts! Even though I bought it over a year ago, I was finally able to use it and I think it is discontinued.

Lotd of power

This amp is an old school hard hitter. I had to install a cooling fan to keep it from shutting down after loud volume continued use.[30mins] It now never shuts down.I owned for 6months now

Great amp!

So i have a lincoln navigator. This might be a little too much for my 8" mb quart sub. But it is doing its job real well. This is the first time buying on line from sonicelectrionics but i am very satisfied!

By jesus on April 25, 2016


Great product

This amp is great. Good steady clean power in a dual setup. I'm very impressed.
