Help!! This Dont Make Sense

[tmoney 10+ year member]

Hey guys my buddy has orion 8004 and everytime he turn the gain up it shuts off.BUT when he puts his jl back on the speakers they r find. When we have the gain set low on the front channel, it play fine, but as soon as we gets about say 40% on the front channel, it goes into protect protect mode. The rear channel plays find nomatter where the gain is set to, just the front we r having prblems wit .When i unhook the front speakers from the amp, we can play wit the gain at any levelon the rear. Do u think something is wired wrong in the front speakers or do u think it the amp front channel. I know when we had the crossover out and it went in protect they lit up like a firecracker. but we check all the wiring unless we have polarity cross up somewhere.

okay im going to trythis again. the front channel-whether its the speaker wiring or the amp its self is wat we r having problems wit. if we hook the front speakers to da front channel on the amp, it(the speakers will begain to play.) but as soon as we start to crank the gain on the amp to about 40%, it seem to throw a short or something, but it just shut off into protect mode.the rear chanell of the amp play find on the rear speakers. they r cmx's so i know they can handle 125watts.

I'm not familiar with the protection circuits on that particular amplifier....but many amplifiers will kick into protection if the gain is set to an inappropriately high level due to certain protection circuit(s) being tripped.

So the "problem" might not actually be a problem, but rather the amplifier trying to tell you that you are doing something wrong.

My advice is to disconnect the speakers, grab a DMM and play a test tone and see what the voltage level is on the amplifier's speaker outputs when it shuts down.

Sounds to me like you are either setting the gain too high and your amp is telling you "no", or that maybe you're having a voltage issue, perhaps caused by a poor ground, that is causing your amp to go into protect.
