Hey Isaac i am going through head units every 2 months and when i have the stereo on i can hear noise like it is grounding on something. Is there some common problem i have not heard of? I know i got the wiring right because i got it from crutchfield. The head units usually work fine then just crap out. The one i am having problems with now is 2 mos. old! It will come on after the car is off all night for about 5 seconds then it is gone. I don't think it is broken but i don't know where to start. frown

try ur grounds or live wires could be a short
and if you say you have noise when its on then i'd say you have some sort of interference! best bet is to check all ur connections and wires

Hey guys, I just did a headunit install on my G/F's 2000 Celica GTS. The external amplifier is under the dash on the right side of the glove box. Pull the glove box, and you will see it. There are two harnesses that plug into it. Pull them both, and disregard the one with the thick grey wire like the one up at your headunit. If you go to a stereo store, they give you an adapter harness that has 2 different plugs, one small, one a little larger. If you take the plug you removed from the amp and look, you will see that it is one piece, and has two indentation marks on it on the top, one on each side. If you take the larger aftermarket adapter and hold it up between those two indentations, you will notice that it would plug in provided the sides were cut off... If you do that tho, beware, the wire colors are not the same as the radio, and it will not hook up your front door tweeters. Use the info that the guy posted above and hard wire it in. I made a custom harness w/ 4 sets of speaker wire 2.5 feet long, a yellow power, red memory, and I grounded it out at the support bar directly behind the radio. This works out great! I cut off the stock plugs and hard wired the radio in, but if you were considering selling the car again someday, you could use T-Taps to tap into the wires, that way you retain the stock plug. If anyone has any car audio how to questions, let me know!

Ok, so I am trading in my celica and putting the stock radio back in, It just makes a ticking noise and I get no sound, what is the GRAY/shrink sig shield (all) that was mentioned in the wire codes. Because it appears that the wire inside the shrink has been pulled on and may be thin. I cant think of anything else it could be

I need help wiring an alpine head unit. It's 60watts peak power by 4 channels so i was just going to bypass the factory amplifier so i didn't have to buy a module. I want to be able to use all of my factory speakers on the GTS with my 4-channel head unit. Can i do this...and can someone help my sorry soul in doing it? cry

i just put an alpine CDA-9835 head unit in and i had some difficulty finding the actual wiring codes i needed so it took me awhile but i got it so i figured id help everyone else out who needed it

when you remove the pieces from the center console and remove the factory cd player there are 3 wires that are important from the factory harness

gray with silver dots wire is the 12 volt accessory - red wire on cd player harness
blue with yellow strip is the 12 vlt constant - yellow wire
with with green is the dimmer - orange wire

you will also have to ground the black wire coming out of the after market cd player i did this by crimping a terminal to the end and screwing it into the metal support tube which runs behind where the clock is

now you have to remove the glove box and locate the factory amp when you do you see 2 wiring harnesses remove them and consentrate on the larger one which is on the right or rear

FRONT RIGHT - typically gray on the aftermarket harness
the light green is (-)
blue (+)

FRONT LEFT - typically white
pink (-)
purple (+)

RIGHT REAR - typically purple
red (-)
white (+)

RIGHT LEFT- typically green
black (-)
yellow (+)

u will have to use some additional wire to run from the harness on the back of your aftermarket cd player to the harness from the amp and just install everything back and you should be good using this you actually dont have to buy anything but a little wire and the plastic din cage

Anyone know which wires to tap in order to hook up an aftermarket amp to the stock HU using a low level signal???

I have a single RCA to stereo RCA adapter and need to capture the low level signal between the HU and the factory amp.

Thanks!
