05 VP Coupe

Stereo : Sony Xplod 420gtu
Speakers: Polk 6 1/2's front & Rear 60w RMS
AMP: TIS (ebay kit) (twenty inches strong) 5 channel
Sub: 10" TIS (ebay kit)

RCA's & signal Wires (from Stereo) ran under center console left side
Speaker Wires going back to Speakers from Amp ran down the right side under center console.
Power wire ran under passenger trim panels
Ground sanded paint off under rear passenger seatbelt bolt & secured

*PROBLEM: With engine on: I hear a click noise through the speakers when I apply the brakes, I hear a noise when I turn on the rear defrost, & during low volume can hear noise as well. best described the noise is a whine.

With me running the power on the same side as the antena amp & all the other wires on that side... is this why the noise..?

*One issue though.... I was running a kenwood amp prior with same wiring & had no noise... the only difference was No sub & the RCA's were sending signal to the Amp (with the TIS amp I am using High Input setup)

Please help with any info possible.... I don't want to start installing "noise" filters etc... until I rule out any other issues I don't see.

Thanks in Advance !!! Scot

power wire should be by itself on one side only. speaker wire and rcas should be on opposite side. stereo should be connected directly to battery + terminal, and ground should be attached to a solid chassis ground. do NOT use the stock harness for constant power and ground for the stereo. do not use pnp connectors to hook up the speakers. cut the wires and wrap around the speaker terminals. ive had alot of static because those stupid connectors were not tight, or water got in and corroded the metal.

Most "noise" is caused by a ground loop. If you have more than two amps, trying grounding it in the same place. Make sure you don't have two or more devices connected to the same ground through the same path. I'm sure it's not caused by the devices; it's in your wiring. Good luck.

it could also be the quality of the amp. you really get what you pay for quality wise.

Interesting. Since my sound system install, I've been noticing a seriously annoying static noise from the back speakers every time I open the throttle, and the more I open the throttle, the more intense the static noise becomes.

So this is because the wires were not tight enough on the back speakers? I used female disconnector crimps to connect the speaker wires to the speakers.

I have a similar problem. just finished installing a infinity reference 5350a. wired it where the power wiring is on the passenger side trim panel, and speaker / rca on the drive side trim panel. i hear a buzz (like fast clicks) only when the engine is running, if i shut the engine off the noise goes away. My ground is connected were all the light bulb connections are getting grounded...underneath the plastic trim in the trunk. hot wire is going directly to the battery.

any suggestions would be appreciated, the only thing i can think of is move the ground and see what happens.

all speaker wiring are soldered on....

here is what i got, xplod gt820ip head unit, polk db651s speakers & 5350a infinity amp. Have not installed my polk 2084dvc subs yet.

From my experience, it's your wires. It's most likely your RCA's. If you use cheap stuff you get "road noise" and if you don't wire your chit correctly your going to spend more time and money believe it or not trying to cheap out on fixing it. Any install I do is always done right. Wire your stereo's harness to an aftermarket harness that plugs right in to your cars harness. Use a brand name amp kit like Rockford Fosgate, Monster, Streetwires, etc. or if you use a cheap kit, just get a higher wattage than required. Please make sure your connections are very tight. From my experience running your cables and wires next to each other doesn't effect anything unless some are exposed and touching.


Bottom line is if the amp is cheap or your wiring kit is cheap or wrong setup (1000 watt amp with a 500 watt kit "wrong"), not connected to vehicle specific harnesses, poor connections or simply cheap RCA's can all be problems now or later but, they will still be problems. You can get the best of the best amp, head units, speakers whatever, if it's not connected right you will have problems.

Also, if you check everything and it's done correctly, look into noise filters.

make sure you run a separate ground wire for the stereo DO NOT use the factory harness ground.

I noticed one more thing, it changes with engine rpm (noise only when engine is running). It does not get any louder only changes pitch.

My wiring is rated for 1200W and my amp is 400W RMS.

What brand is the amp kit? If it's a good brand then, it's a bad connection or RCA's are crap. Is your stereo hooked up with the proper harnesses? The ground from your stereo should be grounded on the metal where the stereo sits. Also some stereos get ground from the outside casing. What do you mean about signal wires?


You know what, did it do this when you first put the system in or after awhile? If it did it awhile after your install then it's got to be your RCA's.

Oh, it is definitly classic road noise from poor quality amp kit or amp install (not trying to sound mean). Normally you shouldn't get road noise from anything other than putting the amp in. Even if it was a poor stereo install, it wouldn't make road noise.

amp is Infinity reference 5350a. I was referring RCA's as signal wires.

I just installed the system yesterday. My head unit was there before. My head is grounded through factory wiring harness. My wiring is all schoche...hopefully i spelled it right.

What are you referring to as road noise, Even if i am sitting idling it will make that buzz as long as the engine is running.

Im going to see if I can make my ground connection better and see what happens.

Here are my sys specs. Sony Xplod GT820IP head unit, Polk db651s speakers (all four), Inifinity reference 5350a amp.

i fixed it. it was a ground loop noise, the rca input & the ground of the amp where at two different levels, that is what the noise was.

used ground loop isolators, they fixed the noise. the noise was low enough that the isolators where able to fix

this may not be the best way but, i did not want to take out all my trim panels out again, to find a better ground and still could have picked it up.

39bucks for three of them, not a bad deal.

Ground Loop --> Guts of it, it means there is an alternate path for the current to flow, causing feed back - hence ground loop.

Message to SKIVY - try these and if they do not work u can return them back. I went to our local radio installer and basically asked the guy if i could try them, he said sure i did they worked and i bought them. they took five minutes to install...

Sorry for the late response but, road noise is the buzzing sound when the car is on and changes with RPM's. Usaully caused by ground loop or bad/cheap RCA's.

I should have been more specific but, it's good you fixed it. I mentioned relocating the ground but, I didn't get specific about the ground loop. Someone should make a sticky about this in detail. It will become a problem for DIY'ers

Yeah, schoche is more of a autoparts store brand but, you are using more than you need so that's OK. Also I just relized that I was answering more than one person, oops.

Just got done reading over all the posts and glad atleast one of you figured it out. I've personally never heard of ground looping. Never experienced it either. My systems, if I ever ground more then one thing, always have distribution blocks. Whether or not that eliminates it, I don't know but one recommendation I did have for you was to unplug the RCA's from the amp and drive around to see if you still hear the sounds. If you do, its a wiring problem, if not then replace those $0.25 RCA's now. Good luck to anyone else that has this problem, but I don't think skivy cares any more or else he figured it out.

Thanks, I was having hard time trying to explain what I had, this is my first ever install...so some of these are new.
