i installed a head unit in my car now my speakers pop when turning it on. I've researched far enough to know the cause of this. Does anyone know where there might be a write up, with what part and where to get it, and how to install it?

 

2005 and up Shaker systems...

5V Fixed Voltage Regulator (Model 7805 from Radioshack)

Voltage Regulator (Shaker 500 Only):

This is needed because the Ford Amplifiers in the Shaker 500 system require only a 5V turn on signal; however the Avic-D3 puts out 12V. This causes a popping sound to be heard every time the car starts up.

To fix this, you must put this regulator (7805 from Radioshack) in between the Blue/White System Remote Control output from the white Pioneer Harness (input) and the 2 Blue/White wires from the small Metra Harness (both go to the output) The middle of the regulator is for the ground. To make this easier, I took 3 pieces of the parking brake leftover wire and attached those to the Regulator, then to the other leads.

Straight from this write-up...

I did try this on my Shaker 1000 and it didn't work, wouldn't power on at all... But I think I wired it wrong, too lazy to pull it out and try again...


I assume its basically the same if you have the Mach 460/1000...

 

Thanks

 

you can also just use a 1.5k ohm resistor, cheaper and easier, wattage rating of the resistor does not matter.
