head unit not turning on, accepts cd but doesnt light up Options

[brianforster]

all the wires are plugged in the right spots and everything appears to be connected right.

does this mean my head unit is messed up?

or the factory 2 amps are messed up?


this is an aftermarket head unit, using the metra 70-8112 harness going through the factory amps.

please help , i jsut want cd capability

ok the head unit has 3 wires that i know need to be connected to get to work

red wire to battery
yellow is mem wire
black (ground)



update: i wired the red and yellow wires together and touched it to POSITIVE of the battery and black to ground and the head unit turned on and worked

so i go to car and keep both the wires together, then i wire it to the yellow wire coming out of the harness and it blinked utnill i actually turned the car on then it stayed on and i was plugging in the preouts for the speakers and i started to smell smoke so i turned it all off.

now i cant even get it to do what i originally posted, i checked all the fuses...

i guess i must have blown something this time


this is so damn complicated
