2nd Gen Non-Engine/Transmission 02 infinity stero problems

[RAndrae]

I have a 2002 quad cab with the infinity cd/stereo/cassette player. all of the left side speakers quit working. The one in the quad door, drivers door, and the A piller. They intermittently come on so know they work. I tried another working stereo with the same results. any ideas???? Thanks

The Infinity system has an amplifier integral to each front door speaker. These amplifiers power the A-piller tweeter and rear door speaker also. It's not uncommon for an amplifier to act up.



The factory service manual has trouble shooting procedures to narrow down where the fault is. PM me if you need copies of the pages.
