kenwood amp problems

[REAA]

Why does my KAC-729S 600w amp turns off when my subs hit a low note. I'm running 8 gauge wire for power and ground, I think that's enough since I the 8 gauge wire barely fits in the amplifier terminals. I had a more powerfull amp conected to the wires before and I never had a problem. and I don't know what to do since I know that the subs are connected properly.

The amp has a screw in the front that says GRD besides the one next to the POWER and REMOTE connections, maybe I'm connecting it wrong. Do I have to ground it in the same location as the other ground and do I have to use 8 gauge wire too? Hope anybody out there has some imformation, I would really appreciate it.

look at ur gain settings.. maybe if it didnt turn on look at ur connections, but the fact that when it hits low, i think its ur gain.. (input level)

I recommend that you use a 4gauge or higher power wire for 600watts; i'm not sure if thats the problem. The gauge you use for the power wire is the same guage you're suppose to use for your ground wire (could someone tell me why?).

I know what you mean by "the 8gauge wire barrely fits into the terminals", but i would think that much watts would accept 4gauge. You do mean 600 RMS right? In my experiences i just shoved a 4gauge wire into a 8gauge barrier spade (the "u" shape crimper connection). Does you'r amp accept bare wire, or are you connecting it that way?

Are your bass boost (reciever or amplifier) turned up high?

and Y didnt I think of THAT... it could be its not getting enough power from the wire u have and when it pulls to much and isnt receiving it, that can make it shut off..
