how many subs are you running on this amp, and how many ohms are they. if the are bridged, try hooking up stereo and see if the problem still occurs. make sure your scrape off all the paint where the amp is grounded to the frame which should be less than a few feet. i'd also recommend running at least a 4ga wire for both your power and ground.

Short inside one of the transistors. This requires very good soldring skills and electrical know-how, and some thermal paste to go between the heat-sink and the transistor. Unfortunatly this is not a cheap repair, probably cost around 100 dollars.

Cheers,

well, hopefully the amplifier was wired correctly. But either way there are so many factors that can cause this problem... But the biggest one is the amplifier must have been sending some distortion to your subwoofers which a subwoofer can take a certain level of distortion and be fine but too much will blow any subwoofer even the highest of high end subs at a high volume... when your subs hit the point of blowing they will tend to just blow out one at a time... they don't just pop both right away. I'd say get the sub that isn't blown off off of the amp before it blows too... distortion is clipping most of the time... when you destroy the subs it will eventually work it's way to the next component in the system which is your amp and then you will be out an amplifier and subs. save yourself the headache.......

First off will the fastener turn ? If not try using a bit of wd-40 and letting it "soak" for a little while . Also be sure you are using a good proper sized Phillips screwdriver . If the fastener still won't turn try using a can of "computer duster " inverted so the liquid comes out , note this will be well below zero degrees , and freeze the screw head , then try turning . If the fastener is stripped and the ttol slips you will have to remove the amp cover and grip it with a pair of vise grips ,pliers or a flat blade screw driver .

You are driving it too hard. If continued, the amp will go into protect mode to save you from yourself.

Yes. Wire the two 2 Ohm speakers in series and connect them to one channel. Connect the 4 Ohm speaker into the other channel. This will give you a balanced 4 Ohm load on each channel.
