Hello all, i'm new here and have a couple questions. My step-son and i were installing his stereo in his truck (1980 Chevy C-10) and we've encountered these problems.

1. there is lots of alternator noise coming over the speakers. We are using heavy gauge wire for both the ground and power source. Both amps are grounded to the seat mounting bolts that go through the truck frame. We are using standard RCA cables from the head unit which is a Premier. Amps are Jensen for the 2 10" subs and a Dual (walmart special) for the 6X9's.

2. when we turn the key off, we get a loud pop over the speakers as the power shuts off. Not sure why?

any help would be appreciated.

thanks

Geoff, your problem is the Pioneer cd player. What you have done, probably inadvertently is dead shorted the rca outputs. If you touch the center pin of a rca cable to ground while the head unit is on, it will dead short the rca and in the case of a Pioneer, it blows a protection fuse inside of the unit. The fuse is not user replaceable, it is a repair only option to properly solve the issue. What you can do in the meantime is to try wrapping a length of ground wire around the exposed metal part of the rca where it connects to the deck and see if this solves the issue.

The pop part of the equation may or may not be solved at the same time. Chances are it will not and it may be the delay circuitry in the amps not functioning properly.

thanks for the information Rob, with the ground wire are you talking about the outer ring of the rca cable itself? I'm thinking you are right about the dead short, my son bought the head unit from a friend and it was probably dead shorted from before. I was extremely careful and made sure everything was turned off when we were installing the RCA's and amps, however i may have inadvertantly done this as well. I'm also assuming if it's the delay circuitry then there is nothing we can do about it?

thanks for the information

Yes, the outer ring of the rca cable is the shield. It is bare at that spot where it connects to the back of the cd player or pigtail coming off of the cd player.
