mach 460 radio interference.. help

[orangemachine]

Hey all, I need some help. Here is the situation...

I just installed a mach 460 in my 00 GT. When I turn the key back, I get perfect radio reception. However, when I turn the key over or start the car, I get absolutely no radio reception. None. I have no idea why. Now, I checked my antenna and its wiring and everything is okay. The antenna is also securely connected to the radio as well. So what in the world could cause this problem.

Also, I had a clarion aftermarket system in there with new wiring/amps/speakers, which I removed. But before I removed this, it also did not get reception when the key is turned over.

Therefore, with two different wiring systems, I do/did not get reception.

Please help. Thanks.

I'm not sure what the problem is but I noticed the same thing with mine today. My reception is crappy with the car running and I can't figure out why. I had the radio on today and, not thinking about it at the time, I was picking up a station that I normally don't pick up at home. I got in the car to start it and the station went to fuzz.

I think it must be some interference somewhere. I noticed mine went bad after my dyno tune and chip install. I thought maybe they knocked the antenna loose but it is fine. I'm going to try a filter and see if it helps. They work when you get alternator noise so maybe it will clear up whatever inteferance I'm getting now. I have an aftermarket head unit connected to the Mach 460 speakers and it used to work fine.

If someone else has an idea blurt it out.

with car running, I get NO reception at all.

Can a tune and chip mess up reception?

Can a tune and chip mess up reception?

I wouldn't think so but that is when I noticed mine went screwy. I still get stations but only about 50% of the distance away from their towers as I used to and a lot of times it fades in and out.

Is there some type of antenna booster or something that strengthens signal? I thought I read something about one and wondered if they are available. How much are they and where could I get one?

Thanks.

Perhaps you need to install a noise filter on the power supply wires. Radio Shack sells them, they are cheap.

I'll check out the noise filter, thanks.

I checked ebay and found some signal amplifiers for car radios. Do they actually work? Anyone have experience with them? They said that the amplifiers add 15db of signal.

about the noise filter... is this it?

how would you install this on a mach 460?

or..

should I buy the ones that just snap on to the power cord? Do they actually work?

I'm thinking more along the lines of this:

The problem isn't power circuit produced I believe but some kind of bleed over the antenna. If you have a chip in the PCM it could be causing the interference since it only happens when the car is running and the PCM is active.

ya, I did some more research about what to do....

I bought little noise filters that snap on...

I bought an antenna noise filter that looks like the xterminator thats linked above...

and I bought an antenna booster to help gain signal.

If one of these things doesn't work, I'm going to be real upset. hehe

Has anyone ever used one of these? results?
