Hi I just got my amp the way I like it, messed with the switched and stuff and got it at a great sound. When I bump it super loud my amp get really hot and shuts off, is this cause im using to much gain? its at max... its usually on really hot days. Should I try turning down my gain and see what happens?

 

Absolutely. Do not be confused by what the gain control is. Yes at medium volumes it appears to function like a volume control. What it really does is match the amp to the deck. Not all decks put out the same amount of power on the RCAs (and why the hell can car audio manufacturers NOT standardize on this already!!!) so you need to set up the amp to put out full power at the same time the deck does. If you have the gain too low then you don't use all your amp, but if you have it too high, you will max out the amp early and then turning the deck up higher than that will only ask the amp to do what it can't and that is where problems start.

Try turning you deck up to 80% and then back your gain down until you can just hear a difference in output. Leave it there and try that for a while and see.
