Do I have a ground issue?

[TheEricHarris]

Got a AVIC-D3 installed last week.

 

Just noticed this today that there is noticeable static when volume is over 8. If I switch to a source with no volume (like the DVD), there is static when volume is at 8 or higher. If I go below 8, no static.

 

All 4 of my interior speakers are amped and my 10" sub is amped. I have Sirius and the PAC steering wheel controls. I grounded the AVIC-D3 to the ground wire going into the OEM stereo wiring harness. I grounded the Sirius and PAC into the main ground wire going to the chasis.

 

Where should I start looking? I'm guessing it's a ground issue but maybe a setting on my AVIC-D3?

 

 

Thanks,

You may have your amplifier's gain settings adjusted wrong, as well.

Good point, I'll play with those tonight. Right now each speaker is right in the middle for gain. The volume sounds sweet (i can crank the avic-d3 to 40 with no distortion on some songs) but I do notice a little static in the background.

 

Another question, which could be related. I have component speakers in the front (crossover going to a tweeter and woofer in the front door). The amp (Alpine MRP-F250) a switch for high pass filter, which is ON. Should I have the high pass filter on the AVIC-D3 on as well? What configuration should I do? I thought the crossover for my components acted as a HPF. I'm confused with so many options LOL

 

 

Thanks!!

Update...played with it during lunch. The "whitenoise/static" is coming from the tweeters. Its mainly noticeable if I use one of the staging settings (Dynamic Theater). If staging is off, not so noticeable. If I unplug the front RCA cables, static goes off.

 

The crossover for the component (where the front tweeter and woofer plug into) has a dB jumper. It can be 0db or 3dB. I have it to 3dB on all 4 of my speakers in the car. Would this affect it?
