So I have a 98 BOSE HU and a 96 BOSE car that is being sold. I had a clarion in there and got rid of the original 96 HU. Well I tried putting the 98 HU in there but as soon as I plugged it in it started making this loud popping noise. The HU wasn't even on and the keys weren't in the ignition. I thought the BOSE units were interchangeable?

 

they are, all units from 95-99, can fit onto any other max 95-99, not sure why you got the popping sound, did you try pluggin back the 96 unit and see if you get the popping sound still?

 

I don't have the 96 like I said above.

 

u sure there not clicking noises because that happened to me it made clicking noises

 

what was making the poping noise? the headunit or the speakers? or the factory amps?
