I have a new to 05 GX470. It is equipped with the TEYES CC3 head unit. I've been thinking of taking this out and going back to stock and using a BT45-TOY adapter.

My problem is, only the drivers lower speaker works. Is this an amplifier issue or are 11 other speakers just blown? Obviously if an amp, I can just pick up another one, but if it's several speakers blown, I'm probably looking at a hefty amount of money.

If I do go back to stock, what part numbers would I need?

That's a real tough question to answer remotely, if I were you I'd use a multimeter at the speaker wires at the back of some speakers to check if speakers are getting a signal from the amp to determine if you have a speaker problem, or an amp/wiring/Teyes issue.
