    • Crisp clear sound. The best quality
Size: 4-Channel 800W
Great amp but I returned it and got the big four for added power. They are owned by stinger now which is interesting. I hope the quality stays the same.

Size: 4-Channel 800W
Awesome amp! If you need 100x4 at 4ohm or 200x4at 2ohm this little amp is what you need! My door speakers finally truly match up with my 1200 rms subs now! My last amp was a taramps ts400x4 so was running 63x4 how I had it wired. This amp makes me wish I had never even wasted my time on that trash taramps! Great sound, loud, and should bring sq into your system! Buy this thing while its on sale! ... show more

Powerful 4 channel amp. I have it running my Alpine Type R 6 x 8 coxial's in the front and rear of my extended cab 2011 Ford F150. It sounds really good. I have a new Tesla type 13" radio with dsp built in and a built in EQ and the control I have with this amp is amazing. The amp is powerful for the price. ... show more

    • Great Amp
Size: 4-Channel 800W
Amp is very well built and has great controllability. Not a fan of the gain sensitivity. It does enable a low buzz from engine whine on both amps i have for midrange and high range control!

Size: 4-Channel 800W
Simple to setup, and powerful. Even with my god awful wiring it still made my car much louder and cleaner sounding than before. Cant wait to test it further once I get my front right speaker working!

    • Poor longevity and poor support from Amazon and audio control.
Size: 4-Channel 800W
Only a few months old, bought in April and it’s the first week of July. Front channel crossover completely gone, music is harsh and tinny.
