It was a bad ground, I choose a better ground point for the rear and everything is golden now. I checked the ohms at the battery and the two points that I am grounding at and they are the same now.
I grounded to one of the seatbelt anchors. I used an ohm meter and hooked a long piece of wire to the negative battery terminal and then just touched my ground point with one probe and the other probe to the wire attached to the battery. At both points I had the same reading so I figured that was a good thing. My whine started to come back which I bet is the ground again. I need to get a good connector and sand down to metal (plus shorten my ground wire which is 12ga. about 4' long that came in a amp kit from walmart)TooTall said:Just out of curiosity, where exactly did you ground at? Reason why I am asking is that I had the same problem. I ended up using the bolt for the LATCH system in the very back of the compartment, by the hatch.
Also, how did you measure the ground again?
I'm pulling straight from the battery, you aren't saying I should be grounding in the engine compartment are you? Just 18" from the unit I'm trying to ground correct?ftnssn said:Your ground point shouldn't really be any more than 18 inches from your power source.
