I bought my car with an after market stereo install in the ashtray area. It has all new wiring (power, ground, speaker wire, etc). The guy I bought it from took his subs and wiring out and i decided to run my wiring for the amp and sub. After I did this everything worked great, sound was amazing. For the amp ground the PO had one sanded down on the trunk lid that I decided to use. Recently though I have been getting so much electrical interference I haven't even been able to listen to my stereo. I turn it up and I just get this horrible sound. I don't know what it could be, some of my ideas have been the power cable I ran along the drivers side has been interfering with the speaker wire (it also runs on that side) bc the subs don't get the interference just the rears and front components which are all aftermarket. It seems like it only happens on bass hits. My other guess is maybe its where the ground is positioned or I have a bad ground somewhere else (deck idk). So basically I am lost and before I start tearing stuff apart and checking everything I wanted to see if anyone else had this problem or has an idea.

Run the speaker wires on the other side of the car and recheck the ground in the trunk. Make sure it's on tight and the surrounding paint is sanded off to bare metal. I usually try to use a meaty metal place like the strut tower to get a good ground.

Ground the RCA's....

I would but the only thing amped in the car are the subs and they are fine. I think I am going to run a ground from the head unit to the battery and hopefully that will solve my problem otherwise I am going to spend a lot of money taking it into an audio shop for them to diagnose the real problem.

check to make sure none of your speaker wires are crossed or grounding out anywhere. does it kinda sound "crunchy" when the bass hits?

A little crunchy but if you go louder it just drowns everything out but voice. Idk how to even explain the noise cracky, crunchy, lol idk

EDIT: I was doing some experimenting and I think it is a bad ground on the deck. Where is the best place to take in your guy's opinion? I think I might just run it to the battery

nope...it's been a little while since i've been behind a gen III dash, but there's gotta be a closer place to ground it than that...

Yeah I really don't want to pull it off, right now for some reason it is run to the trunk which is beyond me why he did that.

There is a good factory ground for interior lights and such on the front passenger side by the door. Look for the hex bolt 1/2 way down from the glove/dash to the floor near the interior sheet metal from floor to the pillar. Might have to pull the carper and padding back to see it. There is already a factory ground wire there that will give it away. Run some wire under the carpet and ground it there. I couldn't get a solid gound at the metal dash brackets behind the ashtray area and ran ground wire there instead. Works perfect.

Thanks man, I'll give this a try and hope that this solves my problem.

I hope so. I didn't run the wiring kit on the same side as my amp power wire to the trunk for just this reason. If it was working well with the current setup I wonder if something hasn't come loose. If you need to rerun the stereo wiring to the trunk you might have to run the wires diagonally once you get to the trunk to make the length work.

I have the headunit up and running and am in the middle of adding an amp. I'll finish it when I have a few hours of free time to finish it up. Mine is a bit more complicated since I have aftermarket component speakers in the doors and I am moving the crossovers from the doors back into the car interior so the door panels fit properly again.

I am going to have to come to a SHOmeet soon so you guys can teach me about these cars bc they really just confuse the **** out of me haha I have been reading so much and still am just lost about these cars. The more I read the more I want to sell the Gen3 for a 1 or 2 MTX. I want to come down to St. Louis and hope I can but working at a local farm and being a full time college student might make it hard during prime harvest season. I should be able to get down there for the day though and stay at a hotel or this girl that I know that lives down there.

Turns out it is NOT the ground or crazy RCAs. I will be taking it to a local shop and be praying they do not charge me an arm and a leg to diagnose/fix. I need that beer money haha

So in one last ditch effort to save some money I decided to see if the speakers were all blown from running the highpass filter on the headunit or if I had a bad headunit. I hooked some of my old speakers up and they did the same thing. So I took another 20 minutes to wire up my Alpine double din that I pulled from my Marauder and everything worked great. Now my next question is, anyone ever do double dins in the V8s? It seems very unpractical with the shifter being there. OR has anyone done flipouts in the ashtray? If no one has tried it I'll probably just order an Alpine single din just because that is the brand I trust and am partial to lol

I don't think the ashtray is wide enough top-to-bottom for a double DIN. (the sides aren't straight, they taper) I have a single DIN in mine. I thought about a flipout but you'd have to be in neutral or drive to even turn the thing on or the screen would bash into the shifter on its way out.

It's bad enough forgetting to shift into N to change CDs and while you're looking in your CD case for the one you want the head unit is trying to eject the CD, hitting the shifter, sucking it back in, then repeating the process until you notice it. :p

Which is partially why I just wired a USB cable up through the console and use my Pioneer's iPod control. Load up the nano, toss it into the console & forget. :)
