ok soo i set out on a mission to install my new head unit, a new 2channel amp to power my sub in the boot of my 1993 es300
ive bypassed the amp already, did pop test on all the speakers and they all work

but--i cant get any power to the head unit...and i also think the amp
i used a voltmeter on all the wires in the dash, after cutting them away from the factory harness, and got nothing on any of them
ive checked every fuse in the car, as well as in the cd player and they are all fine
so now my car is sitting in the driveway pulled apart and silent...please can someone help me get power to it i have nooo idea what ive done wrong!
thanks heeeaps

 

ok! so i found a constant power source in the second harness going to the factory amp under the seat, so just going to run an extension to hook that up the the head unit butt--

a very new problem just clicked to me- i have no acc power wire...
so again no power to the head unit
any help here

 

How did you bypass the amp if you don't mind me asking
