I touched two speaker wires together and amp will not respond
I touched tow speaker wires together and of course the amp stopped. then i tried it about three hours later and the amp worked but i had to plug in the wires and once the wires touched the amp the amp cut out ... so do i have a fried amp or is it just resetting itself?

If you disconnet you speakers and there is no problem, Then it's your speakers.
1. try your speaker wire in one port at a time (may have blown one of the outputs)
2. Check the speaker connections directly on your speakers (not loose or damaged)
3. try a different speaker all together and see if you get sound etc.
4. try a different wire from your speakers to your amp (wire may have shorted out or have breaks)
Hope this helps and please rate. If you require further info please comment and I'll get back to you asap
Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.
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....
If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.
Hi. If you shorted (touched) the speaker wires together, or let them touch the chassis of the car, then it may have locked out. Just turning the amp off and back on will fix this, so it sounds like you have done damage to it. Most amps have a speaker relay which gives a click sound when you turn on. If there is no click, then it may have a power supply failure.
If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.
The positives are connected together and the negatives are connected together. The two pairs of terminals are for convenience. You'd connect one speaker to a pair of positive/negative terminals and you'd connect the other speaker to the remaining pair of positive/negative terminals.
You need to confirm that you have a good signal feeding the amp. If you have another amp in the vehicle, swap the RCA cables between the amps to see if it makes a difference.
You also need to confirm that the speaker are working properly and that there are no broken connections in the wires. If you disconnect the speaker wires from the amp and touch the wires across a D-cell battery (for a fraction of a second), the speaker should pop. if it doesn't, check the wiring to determine why.
The woofer or the wiring may be shorted. Remove the speaker wires from the terminals of the amp and power up the amp. If it powers up, check the wiring and the speaker. If it still goes into protect, the amp may be defective. A short in the wiring or speaker can damage a brand new amp.
I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
