Will amp gains cause a amp to shut off. ??

[Zrain25]

Ok well yesterday was my first post. My amp blew so I went out in the morning and picked up a alpine mrx-v70 or something it's a 5 channel. 400.00 dollars later and my system is bumpin. I ajustment the gains because the amp was shutting off.so I turned the gains down till it would stop shutting down. The speakers were very loud and clear and cleaned up and left it at that. Put about 40 min of music on the amp the. Tonight I got in turned up the volume and it shut off at 3/4 volume. So I turned gain down a little more and now it's fine agian??

Y was it fine before then all of the sudden the gain need to be lower.

My truck has two battery's so I don't thinks it's a power issue

Is the amp stable for the ohm load you are trying to run?

^^^ this or bad ground

Ambient environment shouldn't cause any decent amp to turn off.

Sounds like a wiring issue, and a gain setting issue.

Set your gains with a DMM. Make sure you're using adequate sized wire. Make sure you have a good ground. Make sure your sub and speakers are wired to proper ohm loads.

I don't get what u mean by ohm loads. How can u just that. I never messed with that. My power and ground wire are plenty thick. Speakers and sub are wired correctly. I had the gain almost half way up. My hu puts out 4v but I didn't measures what the gain was at the amp. I just turned down the gain to 1/4 and everything is good. I could go all the way to 35 without it shutting down it was shutting down at 28 - 30

If you don't know what an ohm load is how do you know the speakers and sub is wired correctly?
