This is with the 7” head unit?I cannot get the PAC to work without static/hum.
power is ran on drivers side, ground is to factory ground location, speaker wire is away from power, rcas are passenger side.
static is less when gain turned down. When using multimeter and setting gain to appropriate rms (for my 6.5’s that are 100 watts rms) I am sending only 60 watts and the static is insane.
spoke with pac on the phone, tried 3 different ones, had local shop debug install with different rca’s and other wires with no luck.
it appears for me it is the head unit sending a noisy signal out and my amp intensifying that noise via gain. I didn’t spend $1600 to be at low gain!
I hope the JL audio fix 86 will clean the head unit signal and correct my issue.
What other amps/speakers are you running all the way around?
Were new speaker wires ran for all speakers or do you have some factory speaker wire still being used?
Did you talk to PAC & troubleshoot or did your shop talk to them?
The PAC EQ is off?
What about rest of dip switch settings - where are they at?
You said “factory ground” is used - there are many spots that can be used. Which one & I know some with no issue have sanded/buffed metal contact to ensure best ground. Trying a different spot to ground should have been tried.
Only reason I ask these questions is because on this forum, someone had a similar issue - even after swapping out the PAC device for a DSP. Forget what the final resolution was.
