[B Slaps]

i was just talkin to colt about talking to steve or david about making a section on helping people repair audio equipment, beats paying high cost repairs from audio companies. dunno how thats gonna go though, might be coo tho. just a thought

[Beanz]

does it also do this alternator hiss if say you have the higher pioneers like say the ones that have the wires (ETC,sub front rear)

The internal ground is fused. When this fuse pops then good luck getting a ground.

That is funny. A fused ground wire...

That picture is old, I remember seeing it and having to do that to some 7700s... so that was probably 3years ago? definitely works though.

The RCA's ground track in a lot of Pioneers is fused. It's called Fusible Link and it's there so that if the ground wire falls out of your amp and the amp tries to ground through your RCA cables the fuse will pop and protect the RCAs and the headunit.

The most common way that people pop their fusible links is by unplugging the RCAs from either the headunit or the amp while the headunit is turned on. Almost certain way to pop the fuses EDIT: Or connecting the RCAs to the amp before they connect the ground wire...

I don't know why they do it, almost everyone I know with a Pioneer has popped the fusible link at one time or another.

One easy way to tell for sure if you have this problem or if the noise comes from elsewhere is by seeing if you have a pop when you turn the volume from 0 to 1. If you do, it's definitely Fusible Link.
