CL-51 Comps

[Dungmaggot]

I just installed the CL-51 Pro component set. Everything sounded really good except when I could hear a small amount of very high pitched static coming from the tweets. I've never installed a car stereo setup before so I assumed it was just some noise that my iPod cable was picking up and passing onto the speakers. I dont know how else to describe the noise other than two pennies rubbing and vibrating against each other really really fast. Anyway, the sound only happened at first with the iPod and then only when the song hit certain frequencies but then it started happening over Sirius, then AM/FM, and now CD's. Its also gotten much louder and much more frequent. I haven't even had these speaker installed for two weeks yet, could the tweets be blown? I followed the installation instructions exactly and I did a ton research on the internet before I installed anything so I knew what I was doing. Any ideas?

Edit: I forgot to mention that at first it was only noticable from the right tweet, now its both.

At first I thought "Ipod" there is your problem; however since it does it on other sources that eliminates one idea (or does it). First I would start with obvious and simple solutions. Disconnect any (or every) speaker which makes the noise. Then connect a different speaker, any speaker you can find (while keeping in mind frequency range, volume and such). If this different speaker does not make the noise at all (make sure you try different sources and different volume levels) then the speaker or speakers are your problem. If that was the problem it is possiable some type of ipod noise could have caused your speakers to malfunction (depending on how it was connected), as something like that can damage your speakers. Now if this does not solve your problem you will need to check for other solutions. Now you want to be sure to check only one thing at a time. Do you have an amplifier or any processor installed? if so go around them (each one seperatly) and then check to see if you still have the problem. If not then there is your solution. If you still have the problem then keep checking. After the speakers I would try the crossovers first and then your head unit, and then move to amps and such. This could be as simple as the speakers being damaged or even a bad ground. On the other hand it could be almost anything and without actually hearing it I cannot tell you exactly how to fix the situation. If you have some spare audio equipment this will be helpfull as changing RCA's, the HU and things like that can be completed easier. Anyway the best advice I can give is start simple then go to more complex and do and then check only one thing at a time.

Oh heck I didn't think of this but do you have an amplifier installed?

If so are your RCA's run close to your power wire? or are there any angles in the way your power wire is run?

If you do have an amplifier and all the wires are run together or close I would try to seperate them.

Yes, I have a US Acoustics 4085 amp. Right now Channel 1 goes to the front drivers comp, channel 2 to the front passenger comp, and 3 & 4 are bridged to a rear sub. There is about 12" between the power cable run and the RCA's and the power cable is almost a perfectly straight run to the fuse and then to the battery. I'll to disconnect parts of the components and see what happens but unfortunitly I don't have spare parts I can substitute in. Hopefully I'll discover something and be able to report back
