Lets start with an explanation of my setup: 89' Chevy S-10 Blazer w/ a 4.3 litre engine Premier 600R head unit Poweracoustik 2-APC1400 (don't laugh) Poweracoustik HMR800-4X 3 12OHM JL AUDIO 12W0s 2 Pioneer TS-P462 4x6 plates in the dash 2 Pioneer TS-A6986 6x9s in the rear The HMR800-4X runs my 4x6 plates and 6x9s, while the 2APC1400 drives my subs. I am using all 4 guage wiring minus about a foot of 8 guage between the dist. blocks and the amps. I also have mid-quality soundquest RCAs from front to back.
QUESTION: I have heard that S-10's have a ground loop problem. Well at least from everyone I have asked. My Blazer sure does. Has anyone had similar problems? It has a slight tick when idling and my CD-player is below about 8. When I accelerate and I do not have the stereo turned up past 8, there is a whine that follows the engine RPMs, but if the player is higher than 8, you cannot hear it at all. This has not bothered me before, but within a week, I plan on putting 6.5s in the doors and I do not want to hear this whine/tick anymore. I have put up with it for over a year now.

Put the h/u ground directly to the firewall instead of using the one on the factory plug if that truck is notorious for a ground loop problem. Make sure the battery is ground well....maybe bump it up to 4 ga. also. Make sure your system ground in the rear is solid as well.

It could be a radiated noise. I have a '91 Jimmy and I have a slight whine/popping that comes in from somewhere in the dash cavity. I didn't have it whan I had my Alpine 3331 EQ and Alpine deck, but when I changed to my EQ to a PPI EQP, it showed up big time. I got some "Mumetal" from my local shop and lined my radio cavity with it. This helped a lot... Be careful with this stuff, as it is sharp. It's like a lead foil type material. It's said to help reject noise.
Good luck!

I had an 84 s-10 that had a huge noise problem, and as stated in a previous post it is radiated noise . In fact I could remove the deck and the amp from the system and the dash speakers would make a small whine with only speaker wires hooked up to them . WIERD !

Would suggest doing the following in this order. Ground your cd player to the firewall or other chassis attached metal. Didn't work? Connect it back to original. Try this next. Take all your ground wires from your amps, and run them into a distribution block and run a 4 awg wire to the floor. Make sure this connection is decent. You don't have to get crazy with it and scrape all the paint off, just make sure there is no rust or anything else. Didn't work? Keep it that way anyway, it sounds better. Next. Connect a 4 awg wire from battery to the firewall, then connect your cd player grounf to the firewall. Didn't work? Next. Temporarily switch which amp are running which speakers. Take the amp that is running your subs and run your highs into it. Noise still there? If not, then either keep it this way or replace your highs amp, its possibly bad. Didn't work, try this. Disconnect your sub amp completely. Noise still there? If not, then your sub amp is damaged. Try all this, if it doesn't work, run your truck off a cliff, but remember to jump out. hehe...just kidding. GOOD LUCK!!
