So I have a 1999 Ram QC 4X4 V-10, OEM radio with the mini amps in main doors.

My problem is that I have noticed that as of the last month there has been a lot of electrical feed back in my radio speakers, like a resistor isn't working or something. I can hear the turn signals, medium engine RPM noise, and if I switch blower controls and what not. The louder I turn up the radio the louder the fuzz so it is defiantly coming through. I can hear "pops" during the change overs like that on the blower settings.

What is the problem here? I searched the TSB's and came up with nothing but I am sure I have seen something, some ware, at some point. I see a ground might be to blame, but which one and where is it at? Or is this a suppressor or something?

 

Maybe try a power line filter?

 

The most common cause I've seen for that is one or more failed diodes in the (alternator's) rectifier. If it were without engine whine in the speakers I'd lean more toward just a failed ground, but with the engine noise it's smelling a lot like a bad rectifier. I'd check the grounds, particularly the one on the driver's side below the dash, but if that turns up nothing it's a good time to suspect the alternator.

 

I'll try that one tomorrow.

 

Grounds do not just "go bad" like that unless you have recently done something to the truck.

 

I haven't done anything other than moving.

The thing is it doesn't make sense, and that is why I posted. Something has gone array and that is what I don't understand. I'm even using the resistor plus plugs as OEM call for. So I am looking for answers outside the box.

 

Had the same problem on my Yota a little while back..Changed plug wires and problem went away.

 

All electrical connections that live in open air are susceptible to corrosion, and all mechanical connections on a motor vehicle are subjected to shock and vibration. So again I say:

 

Well it looks like I lied, well I need to correct myself.


I always listen to the radio, well I plugged in a CD and guess what? No electronic sound at all. It plays flawlessly and clear. Then I tried the Tape player and it works fine as well. So it looks like this is simply an issue with the radio wave portion only. So anything else ring a bell because I'm at a loss. I haven't checked the ground under the dash yet because of the holiday, but I will this weekend. What else am I missing?

I am using the Q style Champion plugs with the double resistor as noted with the OEM so I know it's not that. The only other thing I can think of is maybe the plug wires because they are about 3-4 years old, they are an off brand (Max Protection * Max Power) spark plug wires that look like 8mm wires made by Federal-Mogul.

I plan on buying new 8.5mm Red MSD wires as they just kick *** but planed on doing that during the winter months as well as some front end work.

 

Check your antenna ground.
