Noise, computer maybe?

[rrmccabe]

This isnt an issue with the Z2 but I have noise in my speakers when no audio is coming from the headunit.

 

I think its picking it up on the low level RCA cable(s).

 

I have monster cable preamp running from the Headunit to the amp in back of truck (trailblazer). This is the 3 pairs in one cable type.

 

I can unplug the RCAs from the amp and it stops.

 

The noise is pulsing and has somewhat of a pattern. I am pretty its computer noise.

 

Any suggestions?

did you run yor rca's and power cable down the same side of the car?

[rrmccabe]

Nope. I ran my 4 gauge power down drivers sill plate and RCA's down passenger side. Both sides have looms from the factory though.

[rrmccabe]

I read a lot on caraudio.com and it sounds like Pioneer is really bad about ground loops.

 

I made this cable (the wire goes to sheild) and installed it in just one of my RCA lines and noise went away. I still get a few odd noises on and off from heated seats, etc. I plan to do the other 5 !

I'd send the unit back....Mine doesn't have it.

 

the only noice I ever hear out of my AVIC is the cooling fans, especially during a phone conversation...and that's really only with the engine off(loud ass GM 6L w/ dual magna's)

Yep, I am sure I can.

 

Its a lot easier than soldering to the connectors like they were doing on that site.

Something you might consider is this.

I would have went this route but did not want to wait. Remove the plastic and add a ring terminal around it and tighten nut.

 

I think this was a better setup but cant find locally.

cheapo 1000w US Acoustics for subs only.

 

Factory Bose amp

 

I'm assuming my PAC adapter(for Bose amp) filters the noice?

and what is the point of that part ?

Same thing as what I did. Allows you to ground the sheild of the RCAs at the head unit end.

 

In this case you would just remove the plastic piece shown in that picture and use a ring terminal liks this http://tbn0.google.com/images?q=tbn:lL7 ... rminal.jpg
