American Bass VFL-500.1

[caraudioguy2100]

Amp powers up and plays audio perfectly .

Problem is I get a static sound through the output .

From rca shield ground to amps main ground terminal I get 1k ohm

I get 1 volt of DC voltage on the rca shield grounds using amps ground terminal as reference

I get 2 volts of DC voltage on the heatsink also black probe on amps ground terminal red probe on heatsink


Any ideas ?

Anyone know what could cause the heatsink and the rca shield grounds to have 2 volts on them ?

2v is insignificant, generally. Ground the heatsink and see if the 12v current draw increases.
