SOURCE: Can it Be Fixed

Nothing should have been damaged. I would assume the speaker output shorted in one way or another...did you have a speaker hooked up? You most likely blew the output transistors and they ALL need to be replaced as one going bad will kill the rest since they're so sensitive. At least the PSU, seemingly, wasn't damaged. Contact www.audiotekx.com, ask for Jason, he's excellent at repairing amps and has great pricing.

SOURCE: sir i have seriouse Problem

I can't find any information on that model. My suggestion is to hook it up and see how it preforms. You will know right away if you were lied to. Please remember to leave good feedback.

SOURCE: infinity 336rms amp worked for over a year then one day stopped?

check your fuses. Also check the power wire connection to the amp and then the ground source maybe move that if there is paint under it. check fuses on the amp. Check ohm load to the amp from the speakers.

SOURCE: Amp won't power up,anymore! Even with new parts installed,removed

Hiya, dont have a diag either what you will have to try and is compare the left channel with the right. There will be 2 driver transistors (also likely on heatsink) close to the outputs. Check which driver drives which output on the left, then match it on the right. Those same drivers could very well also be a problem on the right as they often go with the outputs. There is a possibilty they have smoked again. See here to test FETS
http://www.4qdtec.com/mostest.html

Basically the left will match the right but not similar locations but definitely by track joins.

Also check the power resistors at the output. Often also go.

Hope that helps

SOURCE: mtx thunder 1500 watt amp no sound

Even if there is no visible damage, it could be that one of the transistors is blown, Use a multimeter to check the resistance of the transistors.

What would cause 1 channel of a Rockford Fosgate T800.4ad 4 channel Amp to fry speakers while there are no such problems with the other 3 channels?


Question: what starts to smoke, the speaker or the amp? I'm assuming it's the amp. It cant be a fuse because that's what fuses are for to cut the power on an overload or surge. I would have a look at you circuit board for the amp My guess is what you;ll find is a burnt spot on the board and that will tell you what component is bad and needs replacing. Good Luck

My son accidentally the pos and neg speaker wires together and the fuses blew on the amp and now the power light wont come on at all do you think the amp is damaged?


If I had to guess by touching the positive and the negative terminals together it probably fried up the transistors. While back I did the same to my amp and poof amp no longer worked. Took the amp apart to find the transistors fried up. Ordered them from the manufacturer but never installed them, ended up buying a new amp. Mainly, replacing the amp doesn't mean it would fix the problem....

Im looking for a curcuit diagram for the switchmode power supply in my Behringer PMP3000.


If the supply failed I can tell you which parts to replace... and if it failed there may be a failure in the power amp that caused it. You can contact be directely at fredy2 @ aol.com... put Behringer in the subject.

The supply when it fails takes out eleven components including two expensive IGBT transistors. If the rearmost amp fried, add at least four more components and a lot of work carving out burned board and wiring around the blown circuit traces.

I am looking for a replacement sub amplifier,


Or you could just write of the built-in amp, disconnect the sub from it and run the driver's leads outside the box, buy any decent amp, connect it to the LFE feed for inout and the bass driver for output and carry on.

That's what I did when a second copy of a powered sub died the same way the first one did.

My kicker amp is old but worked great. i hooked it up yesterday and it was fine, then just quit. the green lights still on though. could it be fried ?


mine kind of did same thing was working fine, then intermittenly, then not at all. took it apart today and two transistors are blown. might check those. take cover off bottom, then the aluminum plates towards the outer edges of circuit board. transistors are under those plates. look for any that are burnt. Can buy new ones for like 2-3 bucks, solder em in, and you're good to go. they fry from amp getting too hot. could be from running it too long or wiring it up at too low of an impedence level, making it run much harder and hotter.

The problem are worsen that before. It is wisely to replace both left and right amplifier
IC, but make ensure that the power supply feed a good amount of voltage to amplifier,
Also a strong good signal. Be sure to measure it.
