    The stock amp in my 2010 Prius went out and there is not audio in my car.

    If I replace the stock amp - Part # 86280-0W622 - with a non-JBL amp, will it work with my existing controls/nav/bluetooth/etc. system, or must I replace with the OEM amp?

    Thanks!

    Are you 100% sure the amp went out? Does voice command work? AFAIK there's no none JBL amp for 2010. If you must replace the amp then only the OEM JBL amp will work.

    Thanks for the reply!

    The dealership ran a diagnostic and said that's what was wrong with the audio. I can still make calls over bluetooth, but the radio/cd/sat does not work. If I turn the volume knob, nothing even shows up on the screen. They wanted ~$1,200 to replace it. I took the passenger seat out and the amp in <10 minutes. I've found the amp online for around $300, but i'm a bit wary about buying a used one.

    Any recommendations?

    If you can make calls, then the amp is still working. The head unit has no way of powering the speakers. judging by what you said,
    It sounds like the headunit is bad and not the amp.

    Would the diagnostic the dealership did distinguish between the amp being out versus the head unit?
    This conversation is greatly appreciated!

    I bought a replacement stock amplifier for $250 and swapped it out in about 20minutes. Everything works just fine now! I'm so glad to have sound in my car after not having it for a few months!

    Good to know. Was the replacement you bought new? Makes you wonder about the dealership's quote...

    We have the JBL. I noticed the box under passenger seat, though it was some computer, didn't realize, lol.

    Nope - which is why it was cheaper. It works just as good though. Bought it from "basicauto5537" off eBay. Probably from a wrecked car. I don't care where it came from as long as it works! Haha

    Hello. A reply on a very old post, but maybe it will help somebody.

    My JBL 86280-0w831 had suddenly no audio at all. Also when turning the volumeknob, nothing changed on the display.

    I found out that the 30Amp fuse for audio had blown. Replace once and it blew again. After totally unplug the JBL under the seat, the fuse didn't blew anymore, so problem was not in wiring but in the JBL module.

    I took the JBL apart, did some measurements and found out that the zenerdiode (SM6A27, just below the connector) was shorten.
    This zener should protect the amp from powersurge, but now it was the cause of blewing the fuse.

    I removed the zenerdiode, (for diagnostic use) and audio worked fine and fuse didn't blow.

    I will replace the zenerdiode (€5) and audio is fine again.

    I guess this zenerdiode is in many "totaly silence"problems the cause, and replacing the whole JBL box will not be nessesary.
