Why the **** did my amp overheat?

[ls2poweredgoat 5,000+ posts]

Orion 6002 powering ID OEM's, gain is *about* half way up...

Was at full tilt all the way today for a solid hour...**** thing cut out...turned the volume down for a few minutes, then came back on.

Got to grandma's house and the thing was stupid hot, couldn't even touch it. I actually leaned over to look to make sure there was no loose wiring, and I burned my forearm on the stupid thing.

I haven't had an amp overheat on me in over 3 years, and the last amp that did it was a POS Audiobahn.

Here is a pic of where it's installed...

Maybe your having low voltage?

does the sun shine in where your amps are? mine did that and it make it over heat like a bish' so i moved it under the sub box.

My amp overheated the other day after a 40 minute drive with it turned up. It just went into protect. Turned out my fan quit working in the amp.

check your ground

why your speaker wire looks all fucked?

Hmmm.... Hard to say, really. See, the mosfets have internal diodes to prevent them from reverse polarity voltages. ( Mosfets only conduct in one direction ). These diodes can dissipate heat when current is flowing through them, just like any normal diode. Theoretically you can create a voltage when you move the speaker cone without an input, say for example you have no input to the amp specified and you have your subs on, with the speakers in the trunk. The air pressure will move the cones of the speakers, and create voltage on their coils, and be shorted out by the internal diodes of the mosfets. This is highly random and probably is not your problem, but just throwing it out there. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

There are a lot of things that will cause heating. Can range from either your audio driver or SMPS driver starting to fail, to the mosfets starting to fail and dissipate more with the I*I*Rdon losses, Rdon specifically going up.

My voltage was not low..and I've had the same grounds for well over a year now..

Shitty amp maybe?? //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Gains on the amp were set too high. My XX Cyclops did the same, I was clipping it.

It's 1/2 way at the most..running at 4-ohm stereo....that's no excuse.

Now if the way were to be bridged, with the gain 3/4 of the way up..then yes, I would understand it overheating.

I don't give a shit if the gain was at a 1/4, that doesn't mean you're not clipping it. I wouldn't know, I don't work on amps or anything //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Gain is used to match input signal. If the gain is set to a voltage that is lower than the input signal, and driven hard, the parts start to heat up. You're clipping, you just can't tell.

That's Knu wire. I almost bought that stuff.

Pull the dong out of your ***. I'm sorry I don't have the infinite knowledge that you have on cars or amps.

check your ground im telling u it might be loose or have rust on the spot i had a very similar problem my ground was loose
