Amp not coming on...HELP!

[EarthWormZim]

A couple of days ago, my brother was jamming to the stereo (with the volume up really loud), and he went to turn up the volume, and accidentally pressed the source button, thereby switching it from the Auxilliary source to the FM source.

Anywho, FM apparently has tons more bass. He says that he took a few seconds to marvel at how much the windows and shit were vibrating, and then, all of the sudden, OFF went everything (except for the CD deck).

As of now, the CD deck still comes on, and judging from the analyzer on the display, it is still getting signal from my mp3 player...but, the speakers are SILENT. When I look at the amps, it does not even appear that they are even coming on.

So, I checked my auto manual, to see if it is/was a fuse, and that does not seem to be the case. Then, I checked the fuse on the battery...and, again, that does not seem to be the case.

So...

Any suggestions?

I have a suspicion that it may be some type of current overflow protection on the amp, and that I might need to press some type of reset button...but I don't know even know if the amp has such a thing.

Oh, btw, I have a Sony X-Plod 1000 W 2-channel sub amp and a 600 W 4-channel regular amp that is hooked up in line to the 1000 W amp.

Help!

are the amps coming on even? If the amps are not coming on. Exactly how are you "checking" the fuses. With my fuses that i blow i have to use a test light to see if they are blown because they don't look blown all the time.

check the inline fuse on your power wire, check the amp fuses, then if every thing there is good, get a digital multimeter (only about 20 buck VERY GOOD TOOL TO HAVE) put it on AC and test the output of your amp if you dont get any voltage it is in your amp, if you do its in your speakers. and does your amp have a protect mode if so see if it came on. also it could of been the distortion that caused this not the amount of power, because FM radio is loaded with distortion.

You may have roasted those amps.. but I doubt it. Sounds more like an inline fuse problem. Like the poster above me mentioned.. get a voltmeter and check continuity on the fuse. If both amps are recieving no power that is most likely the problem and that is where I would start looking for the problem.

If it's not the main fuse.. work your way down the power line until you find the problem.

Thanks guys. Your quickness to respond was amazing.

I did find the problem. Well, more specifically, my friend found the problem. This friend of mine took out his little test light, and checked the fuse on the battery. Remember, I only looked for a visible marking on the fuse (through the plastic encasement), and from what I could see, there was nothing wrong with the fuse. Anywho...he determined that it was the fuse, and when we took it out, the fuse had been severed at the very end, right at the little silver part at the end of the glass tubing. If there are technical terms for all these parts, pardon me for sounding dumb describing them the way I do. I'm not an expert in these issues.

Again, thanks...

It's working great now.

Oh, btw...Jacko, you hit it right on the nose!!!

Yes, the test light is a marvelous invention!
