i got an alpine head unit... right now its just grounded through the harness (best buy did it)....
i get some whining noise that i hate..... so i was told i should do a chassis ground of the head unit...
can i do this chassis ground as well as leave the harness ground? (best buy warranty reasons)...
Also... crutchfield says to ground at the same location as the amp... (which is in the trunk)... some other websites say that is a common misconception... im so confused...
where should i do my chassis ground to?... the trunk or in the front??..
