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

[brianforster]

ok thank you

[brianforster]

well this morning i wired it to the battery and now it turns on but nothing comes out of the speakers

we alsu used a mini jack to female rca to male rca (or however thats sposed to go) to plug a portable cd player up to it and nothing came out then either.


im so frustrated right now, my only option i guess is to go home and put the stock head unit in and hope that it still works atleast for the radio, oh yeah my electric antenna is broken too so i only get 1 station and its crappy and not even clear

toyota makes wonderful cars but damn their wiriing!

Help is on it's way...
I'll do a couple of basic wiring diagrams and PM to you.

EDIT: You have PM.
Please, please get them checked first, they were done from memory.

i dont have it yet



also the stock head unit no longer turns on when plugged in to the main harness

conclusion : this sucks



I am pretty sure its not the stock amps blowing, because if they blew I would still be able to power on.


The only thing I can think of is a problem with the main harness


but this also doesnt solve my problem of no sound.

why did I have to get one with the 8 speaker upgrade and the wiring nightmare!

I'm so pissed right now, I cant even have ONE radio station that comes in crappy instead i get absolutely no music right now.

Just get a after market headunit and it will be fine and from what i've read the system8 will work just fine with it and bypass the factory amp because that might be messing with your system as well.

[brianforster]

I have the 8 speaker upgrade, theres 2 factory amps so I bought the metra harness to include both of them and then all this **** started happening

Im thinking you will have to do some serious custom wiring. It sounds to me that the harness you bought is bupkiss and its not sending the right signals to the right places. Thats most likely why you werent getting any sound when you custom wired the power and grounds. I would say screw the harnesses and just bypass it. Find what color does what and do a real pain in the a$$ job. It would be worth it in the long run with that kind of sound system though. Good luck and I hope this helps. if not give me a nice smack in the face.

I think I might have blown my factory amp what are signs of this?

would the head unit still be able to turn on if i blew the amp?

I aws thinking about bypassing the factory amp like everyone normally does and using hte head units amp + the amp under the seat (my 2nd amp)

I'm pretty sure this will work I just dont exaclty know where to start, I guess its time to do some research

that should get u on the right track.

[brianforster]

thanks droc looking at that now


more update:

i went to walmart and bought the generic toyota harness and disconnected the factory amp and plugged it into the harness and wired the harness to my radio and nothing happened so this leads me to believe that it is not the amp under the AC it is the amp under my seat.

something is shorting, something is not grounded right, something is blown, i am not getting any signal from either the constant power wire or the ACC power wire at any point in this loop of wiring mess toyota calls a premium stereo system.

[brianforster]

damn that pdf didnt realy help because my stock amp isnt that one its a different kind

my stock amp has 3 plugs that go into the side

and my second stock amp (under the seat) has 2 plugs

[brianforster]

and i cant seem to find any clips under the amp just the 3 ones that plugged directly into the side of the amp

1 is really long and rectangular

1 actually fits into the stock wiring harness

and 1 was the plug that goes from that amp to the stock cd player

[Yobbe]

Do you have a tool for measuring the wires ? Checking for fround etc ?

[brianforster]

no unfortunately I dont, but I have tried connecting hte power at several locations and it doesnt evne make my stereo budge

I am pretty sure I blew 1 or both of the stock amps, and now I think I am just going to custom wire my 6.5's in the front and back to my head unit and use that untill I can spend proper amounts of money and get components and 4 inchers for the doors and 6.5's for the back.

it seems to be the only solution
