Connect new headunit using AMP OUTS! CONNECT THE GLI (Ground Loop Isolator) between the RCA cables from the headunit to the RCA that goes to the car speakers in order to prevent the popping sound of discharging Amp.
GET TWO GLIs - ONE FOR THE FRONT AND ONE FOR THE REAR

New headunits don't have "common ground". So you need some kind of filter...the ground loop isolator. Check that you didnt connect the speakers to the headunit amp, that might be a problem too...but i think its just the matter of the ground isolator...

"the GLI's (ground loop isolators) are connected between the LF/RF/LR/RR pre-amp outputs and the harness connections to each channel on the Bose amps. The GLI's will eliminate the pop when changing tracks by preventing a discharge of the Bose amps, as modern stereos don't use common ground."

If you notice, the metra harness has the outers of the rca plugs connected to a ground pin correctly. This is important to reduce interference. There are also GLI's that allow grounding for the RCA's outer ring on the other side. Let me know if you find the problem.

thanks,
Andrew

metra 70-1785 is for gamma headunit users and metra 70-1787 is for the delta headunit.
