i just installed an amp for my mids and highs and it sounded great first but then all of a sudden i started getting a lot of static, i took my whole car apart and realized that when the speaker wires touch anything metal they make the noise, when i hold them in the air the are FINE. there is actually a much longer story that i will type up if anyone thinks it might help them solve my problem. please help.

 

let me get this straight you get static any time your speaker wires touch metal are you talking about your bare speaker wire or the wire with the sheeth still on it... also are you using good quality wire...

 

alright.... here is the long story, i would appreciate anyone that wants to read it... i got an amp installed.. they did a good job.. a few days later i noticed that one speaker wasnt working. i took it back. he showed me it was the amp had a bad chanel i took the amp back to were i purchased it and switched the two.. all of a sudden i have static noise that wasnt there before(i suppose i hooked up a wire wrong) and in the process of trying to fix it, i noticed then whenever the clump of wire(3 sets of rca's, 4 sets of speaker wire) all in plastic touch metal the hissing gets real loud. also the amp cuts out a lot.. its realllll annyoing... i will probably pay sound advice this weekend to take it all apart and start over, but if anyone has any ideas before that. let me know... thanks

 

I wonder if you've got a bad wire or bad connection. Maybe its not holding the wire in the air that fixes things, but the fact that you're moving the wire and temporarily making a better connection. A bad/wire connection might explain the amp cutting out too. I'd double check all of the connections to make sure you've got some good contact.

Do you hear the hiss in all speakers, or just certain ones. If it's just on speaker, that suggests a problem in the wire for that speaker. If it's a few speakers that have the hiss, that suggests to me a problem with your amp or one of the sets of RCA cables.

I do know about sound stuff, but less in particular about car audio. I'm not clear on why you'd have 3 sets of RCA's if your amp is just running mids and highs. If the above testing leads you to think there might be a problem with your RCA's, and if you feel safe doing so, I'd try just connecting one set of RCA's at a time to see if the problem is just in one particular set of RCA cables. Also, depending on what the RCA cables are sending to the amp, maybe connect the RCA cables to a different input to determine if it's the RCA cable, or a particular channel in your amp that's no good.

In the end it might be pointless to do all this testing. I mean what you describe suggests a problem in the installation or hardware, and unless you're going to rerun cables or wires yourself, you might as well let the pros sort it out.
