I understand about cheap installing. thats the weird thing, i did a really good install crimp the works looks awesome. the ground thing i think it might be. I have both amps grounded with the same bolt, so both ends of the ground are on top of each other then bolted down to metal. i think that it is the ground ill find out tomorrow when i change it to a different location and them apart

do the above, and also make sure the rca's and power wire are ran on separate sides of the car. if they get close, the magnetic fields will interfere with each other. if it still does it, i'd try some new rca's. i had this problem once. its caused by cheap equipment and poor installation. not trying to be rude, but thats the truth. another big thing it to check your connections, make sure you crimped them, not just electrical taped them. there are a lot of little things that are probably contributing to this.

its probably the RCA's, but just incase you can also check the ground, make sure the ground is bare metal, not to a tire jack or something, and sand the paint down around it.

Alright, I just installed a second amp to my friends car for his compenet set. I am pretty sure i hooked it up right. I checked all the wires everything seems right. He already had 2 compvr's 12 inch with a sony 760 watt amp installed. After we installed the new 600 watt sony to the compenet set.. when you turn the cd player on the sub hits one time pretty hard, i mean right when you turn the cd player on, before the music. when switch songs while in CD mode it does the same. It is like the Beep is on, but we made sure it was off. any suggestions? the amps are run separte from one and other. each with a 8 gage power wire to the battery. the subs where installed professionally, i basicly installed the other speakers the same way. sorry i cant spell im so tired im about to pass out.

also one time the Offset light came on the sub sony amp.
