Great amp!
Aaron Treadwell on 22/09/2017 5 star rating

This is a superb stylish bit of kit. It’s compact and comes with more than 1200 Watts rms.I bought it to power an alpine SWR-12D4 and it does so with ease! The combination supplies plenty of bass and that’s at half gain, so only pushing the sub at around 600 Watts rms whilst I run it in. Can’t wait to turn it up! The RUX KNOB is a must buy with this amp!

Alpine M12
JOSEPH D on 31/05/2016 4 star rating

This amp is the best iv had in my car audio life. It keeps the 1200w rms through its power supply as you get box rise in a ported box which reduces the power output at it sees a different resistance. As box rises, normal class d amplifiers will down the power output. Iv had a fair few amps but keep coming back to this one. This is the second one I have owned as I sold the last one. What a stupid expensive mistake that was! If you want true power and sound quality this is it. It makes my wind screen flex like something else! This was paired up with a 12" Alpine Type R. What a amazing sound. I have set my gains with a scope so I know I am not clipping (distorting) the signal. The subwoofer struggles with this amp as it starts to smell on heavy bass lines. So be warned! I have now ordered a Phoenix Gold Elite2 12 which is rated at 1200w rms and that should work well with this amp. My only worry is the amp gets very warm quickly. The instructions say it reduces power when hot and then up the power when cool again. But if it's always warm/hot, am I seeing 1200w rms or lower?

High Quality Amp
James on 01/09/2014 5 star rating

one of the best amps out there, recommended to power 2 x Alpine SWR-1522D or SWR-1542D. If you are going to buy this product then the RUX-KNOB is a must have and an alpine head-unit greatly increases its performance because of the headunit's high-tech bass systems.
