Ground Loop Issues
- Thread starter tyusha
- Start date
Firsty/Poser, I am lost. I shortened the ground and power wires, as firsty suggested, and scratched the paint carefully at the ground point, but.... The problem remains the same... pretty loud wine with rear speakers plugged in, and hiss from front speakers as well as some not too noticeable wine from front speakers.... Like i said i am lost....
I am not sure what could still be causing it. The speaker wires that i pulled are too long as well and they are zip tied in small bunches also around the amp... That could be it i guess. Also like firsty said they might be crossing the power wire under the carpet somewhere. Also there is some extra power wire near the battery... Another thing to try is to buy a battery terminal... I don't know... Like before any constructive suggestions welcome....

Sure I did't just not before you posted. (chair)
Things to try:
Be sure that no part of the amp is touching metal. THis means that even the screws securing should not be touching metal.
If you can, swap in a different amplifier
If you can, swap in a different LOC.
Is the LOC grounded? If so, unground it.
Where is the LOC? If its near the power wire, move it.
If you can;t figure it out, I can help you out this weekend, but you'll have to help me paint my kitchen

LOL Firsty... There is no LOC anymore. I have a new headunit remember : )
It's grounded through the ground wire in the stock harness. I believe the amp is not touching metall since its velcroed to the carpet....
I still think I need to go get a good aftermarket positive terminal....
Other than that i have no clue what could be causing it besides the wires interfere with each other.... I just don't know.... I guess like i said, i'll pull out the carpet completely and route the wires carefully.
Can the power wire have any influence on the speaker wires? Can you run those side by side? Can you run power wire and RCA wires together? Can you run Power and ground wire together? Oh i am confused... You installers are crazy people, but i envy you and i want to learn. I AM A SCIENCE MAJOR GOD DAMN IT. I AM PREATTY HANDY TOO... I don't know... I looked at this guy's page and all i can say is he is nuts.... http://www.cardomain.com/memberpage/189943

POwer and speaker typicly can't cause an issue. To be safe, I run speaker wire with the RCAs. The RCA should not be run with the power.
Without seeing the install, all I can think of is that something is busted. Either the RCA are bad, the deck is fried or the amp is a goner.

Hey firsty thanks for the tips on running wires.... I highly doubt the deck is the issue in this case... As i was having that same problem with LOC and the stock HU untill this new deck arrived....
As for the amp, i don't know.... What would lead you to think that a new Clarion Amp would have this sort of problem with it? Is it not uncomon?
I sure as hell hope it is ok, although presumably i still have some sort of warranty with cardomain.... I don't know.... I am gonna make sure that my wiring is not messed up first. And then when that is all squared out i will worry about the amp being fried... I will probably still take you up on your offer to look at it one of the upcoming weekends if it's OK with you of course. We shall see....
am slowly getting all my audio parts together and was thinking of doing most of the install myself.... your trials tyusha are making me think i should just pay some one to do it.... still a ways off, i am getting side tracked b/c i am contemplating a carputer...(and i just blew 175 on a cf intake...) anyways good luck with the ground loop issue... hopefully 1sty can help you out and it isn't your amp, though some of those amps have some pretty cheesy connectors if you pushed in to hard or something you could have a bad connection there, but i don't think that would give you the noise you have...??
I have seen amps cause this issue before, not that amp though as I have never used one. I have seen RCA cables cause it a few times though.
Tsunami brings upa good point. It is not uncommon for amps to break RCA solder joints in the amp causing issues like this. Thats why I would like to see what happens when the RCAs and the Amp are swapped out.

well i did get preatty good as i thought cables. All my wires (except for speakers) are knukonceptz and i though their stuff was good. I tried wiggling the RCA's but that did not cause any noices or issues or whatever. I don't have an extra 4 channel amp laying around like SOME CRAZY INSTALLERS
I will mess with it again soon.

I would not sweat installing the amp yourself. I think you need to be a little anal when you're installing. And buy quality stuff. My speakers preatty far from what would be consedered quality by most on this forum (Lightning Audio). I trully think it's the mess of wires creating this problem. Hopefully it gets resolved before you install your stuff, and i'll have some tips for you.

it will be 2 amps one 4 channel to run my boston z6 speakers, bi ampin em!!! (i just got them monday... whooohoooo!!! (cabpatch) ) and then a d series for my boston 10 inch sub... i still need to get the sub amp and then there is that whole carputer journey i am thinking about enjoying, but i think i may just do the stereo set up first instead of waiting for the carputer... going to use a loc to keep the hu stock, i think the stock set up is just sexy! both amps will be jl audio, i have the e4300 and going with either the 250 slash or the 1400d for the sub..? definatly think i can do it myself but don't want to mess up... once i have all the components (sp?) then i will have to see if what an install will run me...

yeah your system is far more complex and SQ oriented than mine. Weren't you the guy who spent a grand on the Boston Acoustics just a week ago or so? Yeah you're a little nuts too Yeah you should def. find out how much the install will run you. The problem is that it is usually much more expensive to install the components that were not purchased from the installer. But hey if you spend a grand on a set of components you shure as hell should be able to afford the install job
And you're in Main so that means that if you come to one of the nepoc meets i will be able to hear your system one day : )

yeah a lil nuts but i had some (what i thought were pretty sweet) jl component front speakers in my lil 2 door truck and i had 75 watts going to each one and i noticed about a week before i traded it in there was a sound change, when i went to take them out i had blown the psngr side speaker.... i was pretty pissed b/c i had them just over the 1 year warrenty (about 1.5yrs but still!!) so i know a guy who knows a guy kinda thing and got a sweet deal on those Z6's.... back to your prob, you going to figure out that ground loop issue this weekend?
