reedal Posted May 24, 2016 Report Share Posted May 24, 2016 Is it coming through all speakers or just the one that you sit next to? Are you using the passive crossovers that came with the speakers? im just using the stock speakers in my car, 04 tahoe with bose speakers what harness kit did you use to adapt the aftermarket HU to the stock harness? That's more than likely the culprit, since the HU sends signal to the adapter, then to the Bose amp, then to the speakers. The adapter is supposed to retain door chime, correct? So your open door chime is coming through as that noise. That's my assumption, unless you tell me you didn't use an adapter harness...

reedal Posted May 24, 2016 Report Share Posted May 24, 2016 If you still have the OEM radio, hook it back up and see if it disappears, if the noise stops, hook the adapter back up, and if you have a second aftermarket head unit you can test out, that will then rule it down to whether it's the adapter or your head unit.

RageQuitForLife Posted May 24, 2016 Author Report Share Posted May 24, 2016 Cool man. so i put the OEM headunit back in and there was nothing. Then i put the JVC back in again and when i turn the car on with the headunit off, it does the seatbelt/door chimes fine, but once i turn on the radio and open the door it does that weird buzz. i have no clue whats wrong with it. Should i just take it to a shop that knows what they are doing? Link to comment Share on other sites More sharing options...
reedal Posted May 24, 2016 Report Share Posted May 24, 2016 It's either your head unit or the PAC adapter. Look at the pac adapter, there should be a rotary switch with numbers on it, make sure the arrow is pointing to the number 2. If it's not, turn all power off, disconnect the HU from the PAC adapter, then adjust the rotary switch to 2. If that's good, then you can take it to a shop, unless you have a second HU on hand to plug into the adapter.
