Alternater noise in my set up.

Got a real problem... Alternater noise.

Set up.. Audiobahn components front.
Mid range in the back.
Alpine 8inch sub with amp enclosure.

Have two hi/lo converters:

One connected to the rear and one connected to the front.

The gain on my AMP is set at about 30% hi/low converters set to 35%

If I turn the gain up on front channels I get alot of alternator noise. Mainly from tweeters..What should I do?? The installer suggested I buy an inline converter.

What is wrong with my set up? What can I do?

As far as I know you have a bad groud connection, try running it some where else. Anywhere on the frame or something like the bolt the seat belt is bolted to. Make sure it's bare metal.

It's not a bad ground. The first culprit is most likely your line converters...what brand did you use? The second, and MOST COMMON, is your RCA cables, you probably need MUCH better ones. The third, your speaker wire going to the front speakers, is it twisted wire, or did you just tap the factory wires?

are your RCA's running where the power wire is, since the battery is in the trunk there is a power wire connected to your alternator (passenger side)and if the RCA's are too close you will get alt. noise, try running your RCA's along the drivers side of the car. if that doesn't help Try noise filters, they really do work

get the real good noise filter. i still think noise filter helps a lot, but it is completely stopping it. even the shop cannot filter out all the noise for me. it's ignoring when the music is low volume. i have never tried out the line driver or converter. i will see about it.

I was really worried that I would have that kind of problem, so I told my audio installer to run my RCA cables right through the center of the car. That means running the wires under the area of the e-brake. Doing this will require way more labor than running the cable on the sides because you will have to strip many of the interior components. However, I went that way and I don't have problem with noise at all. Good luck

Here's a shot of the RCAs running down the center of the car.
