All these years later, and you are still a life saver. That pesky factory amp becomes a fire hazard as it degrades. When replacing the HU, it sent 12volts to a door speaker and smoked the inside of my truck. My mechanic traced the phantom load to that amp and disconnected one of the connectors that was sending out the voltage. There were still electrical gremlins lurking and when I disconnected the second connector, it all seems fine now. Thanks for your great video!
I have the lx450 with a humming sound using the factory amp . In the lx450 you have to plug the harness into the 2 gray connections he unhooked from the amp at 8:49 . You have to run a 2 foot of wire for every wire on the other end of the harness and feed it into the back of the radio . Bypassing the amp got rid of the humming sound .
Excellent video! Thank you for posting. I have a 1990 HDJ81 RHD here in the US. It has an old “carrozzeria” (pioneer) CD stereo from Japan in it. Limited radio stations. I need to swap everything out. This video was very beneficial.
So if you plug the aftermarket wiring harness between the head unit to the original Toyota plugs (grey) as needed, and simply unplug the (grey) plugs on the OEM Amp, that by-passes it?
Why? Just run new speaker wires. I did a DVD in a 2006 civic ex coupe! The only harness I needed was for the antenna. Also a dash kit! I took the constant power from my old radio also the acc wire.

Thank you! Lovely video mate
isn’t the factory amp in the boot with the factory subwoofer?
what is the part number for the other connector you use? NOT THE TAO2B.

Did you have to do any soldering?
Fried my head unit, probably because I didnt unplug my factory amp
