2011 Tuscon Limited - No sound after ZAP

[rvgenomini]

I put my key in the ignition and turned half way to roll windows up. Heard a
ZAP.

No sound ever since. Radio unit still functions. Audio/sound fuses in panel
are good. Had battery drain issue (hopefully resolved with new battery the
other day).

One shop looked at the issue, said they found nothing.
Took to dealership, said they found nothing and quoted me $8600 to replace
radio unit.
Took to Car Toys, they said they can't diagnose a digital amplifier, removed
my amp to get model number so I can hunt a replacement.

So my question, will replacing my amp with another factory model be worth
my time and money, or are there other options?

Much appreciated, I'm getting the feeling the amp is toast. Excited to hear your results!

I got zero voltage at no volume, not even a mV. Unfotunately this tells it could be the radio not sending a signal.

Does the amp have one of these ports?

Just these, there's no cable for the one port in the 2nd pic (no idea what it's for).

It looks like your amp uses a digital audio signal (spdif). So no way to test that audio signal with a multimeter. I guess your best bet is to buy a used amp and hope it is the issue.

I like the price on that amp you posted, compared to what I've been finding when I match my old model number.

Is there really no way to diagnose the radio unit in a similar fashion?

No idea how. All pins I see are outputs except the power and P/DIF. The other issue is that we do not know if the radio is the one not sending an audio signal.
I think I have an idea.
Would you post a picture of the radio?

I thought maybe we could use a product called add-an-amp for testing. It turns out that will not work with amplified Tucsons.

I would check all fuses in the fuse panel just to make sure they are not blown. If they are not. more than likely the amp is toast sounds like to me. Electronics dont last forever. Car manufacturers use the cheapest methods possible these days

Is the amp you posted above a sufficient replacement for this one?

I checked the ones related to audio/sound, but I can check out all of them and see.

OEM changes part numbers all the time for stupid reasons. Give you an example. My transfer case has 8 different part numbers but they are all the same part just a different revision or different internal part upgraded is all. Sometimes a salvage yard near you will allow you to do a pull a part if you want to yourself and some even do the calculations on what you pay by lbs some do it but the exact part of course. Something to consider if you have something like that near you.

Fuses all look good!

That's good to know. I'll look into a proper replacement, thank you.

That thought did cross my mind. I just checked the Veloster amp pinout. They are wired different.

I'm en route to a salvage yard a couple hours away, will report back. Gonna have them plug it in to my car and see if I get sound.
