I'm running High inputs for everything except for aux. I'm running a CarPC on the Aux IN which I can't set the gains on. When the car is off and I'm using Aux, I can barely hear the music there is so much noise. When I'm not in aux, I can hear it bleed but it's not as loud.. maybe 1/4th. The car is not running during this. If I disconnect the RCA's from the 3sixty the noise goes away completely. I have everything grounded to the same spot (computer, 3sixty, amps).

Any ideas? If I run high level inputs for Front, Rear and Sub, can I still run a low level aux input? That's the only thing I can think might be causing this.

Thank You

either that or a real ****ty output on the car pc. um maybe a line driver will help boost the signal. or ground loop isolator. um how high is the inupt knob on the aux in portion of the 360?

Well, I don't have the remote knob hooked up. I'm going to hook it up tonight. I'm hoping that the default is 100% volume when the knob is unhooked so that I can turn it down.

I think there are two problems however. Gain level and ground noise. I'll post back tonight on how it goes with the remote knob.

I appreciate the response :)

Can't seem to find the remote control. Does anyone know if the aux input is automatically leveled when doing a new install with pink noise / sweeps? I'll run the CD through my computer if it does.

I don't think the CarPC will work going into the AUX in on the 3Sixty. I bet you are getting a ton of noise because your carpc is wired into the cars electrical system...

Call RF Tech@ 800-669-9899 and they should be able to provide some assistance.
