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.

I have had nothing but good to say about boss i have had it now for 1year and it runs with 2-2000watt 12,kenwoods premeirs i just added 2 more boss amps a ph4.600 4 channel and a ph2.1300 and for the money it rocks,i noticed a couple reviews and they said they were disappointed,suggestion adjust your amp or amps if you dont you wont get the sound you are looking for,i think my system for the money now 4,12z 2,6by9z,2 6z and2 6by4z it is sweet and i found the sound that i was looking for!

I bought this last week. It arrived today and I must say im a little pissed i have an spl1000 watt amp and its almost twice as strong as this plus my 2000 watt boss amp was stronger too. it dosent get hot my spl does but it bangs way harder. So if u have 1000 maxxx sub go for it, anything over that and you'll prolly be dissapointed like me. lol

Okay this amp has tons of power while it works do not get me wrong, but I have had two of these and they just quit working. Im running two 15" Merlon subs and they destroy the amp. They are 2000 watt max so the amp should have worked but they never held up. The lights are on and the green power works but no sound comes out. Happened two times with this model and once with the ph3000d. I guess you get what you pay for though.
