I do reccomend this amp highly its a great bargain and can do good numbers on termlab :). But its no 4000 watt amp or even close. I have mine wired to 3 500 watt rms 10s at 6 ohms and when i clamped it im only getting a little over 500 watts rms from this amp. With that being said im still doin a 142.2 on the meter with stock batt and alt with 8 ga wire and no extra batt or cap.
