    • Great 4 channel for the price.

Review Image by Raymond Mccloud Raymond Mccloud
Bought this to upgrade my factory amplifier after replacing my radio, has been working great for over a month now with no issues and does not overheat in the slightest bit, even with it in an area with no air flow in the back of my car. Get no unwanted noise in any of the channels and gets my mids and highs as loud as I want them. Have them powering factory mid-bass and tweeters in my front doors and column, and in the rear a set of pro audio from Skar as well. Would recommend for a cheap 4 channel to anyone needing one. ... show more

    • Great amp
Size: 500 Watt Class A/B Four Channel
I replaced the Mach 460 in my Mustang and use this amp to power the speakers and subwoofer. I have had several systems in my past cars and this one works great. It gives more than enough power to the speakers and the sub thumps like crazy. It is capable of more but I keep it to a reasonable level. The many ways you can customize the amp to your prefer is awesome. I would recommend this to anyone on a budget or just looking for a great amp. ... show more

    • Powerful Amp, Very Happy for the Price I Paid!
Size: 500 Watt Class A/B Four Channel
Review Image by Kameron Kameron
Running 2 skar TX65 coaxial speakers on two channels and 2 skar FSX8’s with crossovers to tweeters on the other two channels. Each channel wired to 4ohm so getting around 75watts each and it gets loud, too loud, hardly ever pushing it to its max. No issues with this amp at all, even after running hard for a half hour, it was warm to the touch but not very hot. ... show more

Bought the speakers first,2 pair of Skar 6x8. Already had a Kenwood dx503 head unit. Great speaker upgrade from factory but they wanted more power! This amp delivered!! After installation and tuning the amp and head unit I couldn't ask for better sound... and for the price point, can't beat it with a stick. 5 stars from me. Thank you Skar audio ... show more
