Printer Friendly Forum Posts - way too much interference

This is what my system consists of as of now.

1 8 Farad Cap
1 Kinetik HC1400
1 Power Acoustic BAMF 4000 Watt amp
1 Precision Power 600/4
Infinity Reference 6X9's in the rear
Infinity Reference 6 1/2's in the doors
2 Directed SX 12's in a Bassworks box
And a pioneer head unit.. Not sure of the model.

Now my problem is whenever I have the key turned forward to the first click I get a popping noise from the speakers, not the subs.
When I go to the second click I get the popping noise with a added whine in the first like 5 seconds.
Then when I actually start the car I get a continuous whining/crackling noise. The whining increases with the RPM and the speakers "pop" with my hazards on.

Solutions I have heard to try are noise filters, static strap, or a High output alternator. Any suggestions? I don't want to waste money just to "try" something to see if it works. Please help.

I think the Pioneer was good enough...No model needed...! Try search feature for more in depth details about this problem.(covered numerous times)

Sounds like a bad install. The EMI is because your signal wires are run too closely to a high current power wire, whether it be the power for your amps or through a factory harness. I'd say pull it all out and start from scratch. What year make and model are we dealing with?

It sounds like one of your RCA's is grounding out either from a screw running through it or it being pinched. This happens when the RCA's aren't kept away from the mounting holes of factory panels. Try disconnecting all the RCA's at the head unit, then plug in a new set of RCA's into the head unit and string it through the car to the amplifiers. Now plug it into the front output and see if the noise is still there. If not, then try it with the other outputs. Make sure that you don't have the head unit on when the RCA's are unplugged or you could cause the issue i am an idiot references above. If the noise goes away, then replace your RCA's. If it's still there, then let us know.

I have a 2001 Chevy Malibu V6 3.1L. I am not very good with running everything myself so I have ABC Warehouse do it. They recently replaced the RCA's yet I am still having the problem.

The problem that caused this is they said the ground shield on one of the RCA's went... It blew both of my amps, the outputs on my radio, and one door speaker along with one rear speaker. Ever since then I have had this annoying static/whine.
I didn't even have my radio up that loud when I all of a sudden heard a pop. I lost sound at first. Then I turned my car back off then on and just the interior speakers worked. Then i did it again and just the subs worked. This happened once or twice more then they were toast.

Not very likely.

Wow...Was this stuff under warranty or did you have to purchase all new equipment...???

I had to purchase all new stuff. I know the manager at ABC so he hooked me up with all new stuff and gave me the radio for free.

Back to the question at hand. Would running a completely different ground to my radio work?

It sounds like you still have a problem with equipment. Was it the set of RCA's they replaced that "the ground shield.... went"? If so, it sounds like they may be liable for the damage. Was all the equipment replaced? If they installed it and there is a noise problem, why aren't you having them fix it?

DYohn, let him know that the shield of the radio did not cause his problems. The problem caused the fuse to open. Over the last 10 years I have probably repaired close to 1000 of these units. Never has there been any mention of, when the noise started, all of my amps went out. The shield fuse opening only causes the noises.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I know I've heard something about a Pioneer head unit in this thread... Wait, now I remember what I was gonna say!!

It sounds like he has more of an issue than just that. I've heard that problem cause horrible engine noise, but not the clicks and pops he described originally from electronics turning on. That's why we need more information.

Stevan - They said there is nothing they can do about it. Said that it is a grounding issue. And that the ground on GM's have always had problems.
Also what more information would you like? I have tried to tell you everything I know.

Does it make the noise with the transmission in reverse?

Ah yes, it might be reverse osmosis double-secret cross-pollinated induction noise. That's a killer. posted_image

Yes it also makes the noise in reverse. Also when the A/C is cranked up you hear another whining noise... Is there a way to record sound or video and upload it here?

-------------
-Chris-

There is always Youtube. Post it there and then post a link here. This Forum's server will edit the link, it will appear to not work. But some of us can get to it and be able to listen. Yes hearing it will help a lot.

Also when You dim and brighten your dash lights rapidly, does that make a futuristic sounding space ship noise?

I am not sure I will have to look into that. But I will try to get a video up ASAP

-------------
-Chris-

So, are you going to answer my questions?

And let us know as soon as you get the video up. I really think that hearing it will open up some new options for us to try.

And if you have a volt ohm meter, unplug all Patch cords from your amps. Check the resistance between the shield of each RCA cable to ground. The cable that is running back to the radio. Not the RCA jacks of the amp.

No it was not the replaced RCA's that the ground shield went on. They said that the ground shield going on the original RCA's was what caused the problem.
All of the equipment has been replaced except for subs and the wiring (except for the new RCAs)

-Chris-

Well if it's not an equipment issue, then it must be a wiring issue. Double check all grounds to make sure they are solid and to bare metal (corrosion, paint and primer free). You might also want to try a different ground location and see if that helps. One thing my boss insists on at work is running a reference ground from the head unit to the amplifiers just to make sure there aren't any voltage differences. And if none of that works, then try the RCA ground solution mentioned earlier.

Earlier you mentioned that all equipment had been replaced. Did that include the Deck?

He said the HU was replaced "for free"...

Yea the radio was replaced for free. Since I am friends with him and the radio was only about a month old he sent it out as defective.

Steven - What do you mean a "reference ground". I understand you said from the head unit to the ground on the amplifiers. Are you talking about the radios ground wire?

I was assuming that the Kinetic battery was under your hood. Where is the second battery grounded? Did they use a factory seat belt bolt? Or did they scrape the paint off of the chassis and drive their own screw through the lug? Have you tried running a 10 Ga. wire from the ground of one battery to the ground of the other battery? Do you own an old fashioned test light with an actual light bulb inside? Not an LED but an actual incandescent light bulb?

What is under the electrical tape, the tape that you can squeeze and make the noise change? You really need to remove that tape and see what has a bad connection.

If the RCA shied continues to blow you MUST have a voltage differential somewhere.

1: Did you disconnect BOTH batteries before re-connecting the RCAs? This is PARAMOUNT when installing a Pioneer head... (You should do it with EVERY radio, but for this very reason you MUST follow this step with a Pioneer.)
2: Where is the second battery grounded?
3: If you (just for the hell of it) touch a jumper from the back of your deck to the RCA shield, (ala the link provided early on in this thread) does the noise subside at all?
3: If you remove the RCAs fron the deck, does the noise subside?
4: Disconnect the output lead from the alternator. Insulate it so it can't short on anything. Are the pops still there with the key in the ACC/RUN position? Start the car. Is the noise still there? (With these steps I am trying to determine if there is something wrong with your alternator.)
5: That glob of tape... What runs in it? Power? Speaker wires? Do you have a Hi2Lo in the system anywhere? Was this a "premium" system of some sort in it's previous life? (is there an OEM amplifier still in the system somewhere?) Why are those wires taped and not crimped, or better still, soldered and shrink-wrapped?

Haem' I am sure he tried grounding the RCA jacks, I mean we only posted, quoted or talked about it like 20 times. I am sure he did it. If you haven't done that yet, let's hold off a bit on that. There are new avenues that have been opened with the discovery of the second battery.

Hey guys I appreciate all the feedback. I was only able to get on here for a short while so I just wanted to let you know I am still looking further into this. I will not have time to answer all the questions nor try anything today seeing as how I am kinda busy. I should be able to get around to it probably by thursday and I can let you guys know the result. I do appreciate all your help. posted_image

-------------
-Chris-

Alright so the result was I tried touching a speaker wire to the ground shield on the RCA and touched it to the radio and the sound completely disappeared. I didn't know where to go from there so I took it to ABC Warehouse since I know the guys there, and told them what I found. They ran a new ground to the radio and that got rid of almost all the noise.. It is very faint now, almost not even noticable. Once again I appreciate everyone's help though.
