Worse amp ever used. Even watched video where it aas tested an your car headunit is way better. Unreal boss would be so willing put something so inferior on market.come on your headunit has more power .just wrong . Even tried cheap passive sub an all it does it make it work.the sound is a train wreck an is know hope to adjust
