Have kicker kx600.1 and protection light comes on when i turn the radio up , i can turn gain down and seems like it will let me turn the radio up a little more but when the bass hits the amp goes into protection then it will go back to green and stay that way as long as i have volume turned down. have a 14g power wire and short ground drilled into the trunk with washer polished the area.

It sounds like you may have the load impedance too low. How many voice coils per woofer? How many ohms is each coil? If you have DVC woofers, are the coils for each woofer wired in series or parallel? Are the speakers wired in series or parallel. Let me know if you need me to clarify anything.

I figured it out!!! Thank yopu for responding though. I had a weak graound signal:)

SOURCE: speakers cut off when bass goes up...

you may be running 2 low of ohm load

SOURCE: cut out

check your ground always bring your ground to the battery

ive been hearing alot of this going on yes you had youre system proffesionaly installed but youre amp is pushing at all its got it must be pushing at 1ohms capacity loud but what you dont realize is that.. do ur home work first some amps say they can handle the power but if you read carefully it would read not stable look up amp on the net before buyin review them first ...but evrything youve got is correct its youre amp it wont burn out but you wont get continous power to ur spkrs ..i recomend installing one amp on each spkr same brand if you prefer in keeping it with a crossover if you dont have one that way they wont over heat and cutt off and you will use less power and get more bass...
