so i am running(or at least trying to) a concord 100 watt amp for my main speakers. It turns on and everything. When i first installed it it powered all 4 of my speakers just find, but then it started to shut down after a while. Then it would start to shut down with all 4 spekaers n no matter what. So then i only ran 2 on it and it was fine for a while, and now it shuts down even at super low volumes, icant figure out why. I also have a punch 45 on my sub and i can crankup the volume all the way and it gets all the power it needs and runs fine. This leads me to beleive that there is something worng with the amp.

i checked for voltage drop as i tunred the amp on and increased the volume, and there was none.

If anyone has any suggestions they would be greatly appreciated.

 

make sure none of the wires are touching... if a hot wire and a ground touched it could do that...

 

How did you check for voltage drop? How are thins grounded? Have the measured the resistance of the speakers?

 

Do you know if it's shutting off, or going into protection?

Where do you have the gain set on the amp?

 

first thing i would do is to check my wiring.. seems like there is a problem in that area
