I do hear some engine whine noise which is very low and hides when i increase the music volume, i read on forums that attaching black (ground) wire to body of the unit too will solve this problem (it does not bother me right now). Engine whine noise is not at all the stereo issue since i did a same install on 98 Honda Accord that has no external amplifier therefore i connected to amplified speakers output and the sound is superb clear and fantastic without absolute no engine whine. This issue is due to the external amp integration and grounding mismatch on speakers. I am sure by doing additional ground connections (that is connecting black wire of car to the body of head unit), even this small issue will go away.

Thank you for the video. I have the same car, 1997 ES300. Does the subwoofer still function after installing the aftermarket head unit?

Yes I do hear sound from all speakers including subwoofer but no BASS, it is more toned and not as rich and stereophonic hifi like original PIONEER one.

Default Harness Wires (nubies)

This Is probably the easiest way (not recommended) to hook your head unit up.
your Harness should hook right up to the factory radio harness in the car. the harness you buy for a new head unit should have a yellow or (constant 12v) red or (12v) black or (ground) blue/white stripe or ( remote ) and 4 plugs. Hook up these wires to the head unit, then you should have 8 speaker wires on the head unit. 4 with a black or etc colored stripe and 4 solid colored. Tape the ends of each wire with the stripe (ground wore) because the ground is already in the car then the last 4 solid colored wires find a way to connect to the four colored plugs (I just wrapped them and black tape(rednecked it) so don't do this unless you have female plugs handy) and you should have temporarily gained all sound and bass your car should have. But please don't leave it this way if you decide to do this. Anyway have a good one everyone
