After installing my new headunit (aftermarket) my speakers are making excessive noise. All the wires are connected properly and the wires are linked to the correct harness wire. Please help

 

Do you have the Bose/Monsoon setup?

 

i just have the bose stock speakers....they didnt make noise before the new installation.

 

Well, I don't know for sure, but I know that the Monsoon Camaro setup has several 2ohm speakers... which would actually RUIN your headunit...

trans am monsoon will NOT ruin the aftermarket headunit.

can you describe the sound a bit more?

it could be a grounding issue, or an alternator whine (new spark plug wires/copper solid core?)

it just depends... give us some more info.

its a constant scratching noise that gets louder once the cd loads.

 

if it's a scratching sound... it's because either your headunit is grounded improperly, or it's defective.

I had a problem where I could hear scratching/hissing when a cd loaded in my pioneer deh-p8600mp and it was a bad RCA protection-fuse.

I had to ground it manually externally...

but most likely you can take care of it by running a new headunit ground.

you have no external amplifier, right?

 

What exactly is an "RCA protection-fuse"? I've never heard of such a thing.

 

I call it the "protection fuse," but the real term is RCA Ground Fuse. It's internal, and to replace it, you have to know your way around a soldering iron.

This fuse is easy to blow, for example, if for some reason your external amplifier is not grounded properly, your amp will try to ground itself through it's RCA connections... sending massive amounts of current though the RCAs, and into the headunit... this is why they have this fuse, to protect the headunit from being severely damaged.

It also works the same way if the headunit is not grounded properly, the headunit will ground itself through it's own RCAs and through the amplifier ground.

just double check all your grounds and let us know if anything is better..

but, [B]1996z28m6[\B], you don't have an external amplifier, right? The only thing you should be worried about are the power and grounds then. You can get interference from the spark plug wires, (especially if they are solid-core,) and if the ground is weak on your headunit, you can hear alternator whine.)

it's either the headunit itself, or a grounding issue... if the deck is under warranty, take it back, (if re-grounding the unit does not help.)

 

From your description of your problem it sounds like a bad ground. Question for you: does the wiring harness you used have a separate ground wire or is it just a plug & play type harness?

As for other comments, my aftermarket H/U has a fuse, but it's right on the back of the unit. Internal RCA Ground Fuse? Huh? "know your way around a soldering iron"? Dude, my soldering iron just has a power plug. I put that in an outlet in the wall and go to town. What more is there?

Scrap, you were asking on another thread about t-top boxes for 4th gens. You should check out www.subthump.com as they seem to have a good rep here. I think the White Rascal has them, check his sig.

As for intereference from spark plug wires, I thought that was only with AM radio? Asking cause I don't know, but my motorcycle has resistors in line towards the end of the spark plug wires, and I've read they're there for reducing AM signal interference. Could be wrong, anyone with more/accurate info feel free to chime in and satisfy my curiosity!

ill try that today.

 

the fuse I am referring to is not the fuse on the back of the headunit... the one I am referring to is internal and protects the RCA circuitry...

the one you are talking about is simply to protect the unit if it starts drawing too much power, (if it internally shorts or something.)
