Hello everyone, I posted a while ago about my D2 not producing sound for no reason and I sent it for repair and it was repaired and i am soo happy. I missed it soo much.

This post os to confirm everything ive done is correct and there isnt something that made my unit's audio output fry.

My Bypass is perfecto i guess. I ground the parking brake wire, and the extra pin. And the bypass worked fine. I am installed new 5 1/4 MTX speakers in the front door the same day that my unit went off.

My unit came with a tag sayig as follows:

Grounding Problems and Resolution

- This unit was recieved with open or burned PC board ground traces

- The most common cause for this failure is undersized wiring or loss of connection of external grounding wires

- check manual for all grounding for item before reinstalling.

If someone could give me an insight if there is something wrong in my setup or what to look for. I am not looking forward to have the same problem again and send my item for another 2 and a half week adventure for repair.

Thank you very much for your time.

what vehicle?

its a 1997 Toyota avalon XLS with factory amplifier. Do you think if i wired the speakers incorrectly it might have short cuircuited my unit?

Are u utilizing the factory amp in the Toyota or are you using a standard Toyota wire harness adapter and bypassing the factory amp?

Chris

well if i remember right, you can grab the speakers from the amp with the standard wire harness. instead of plugging that harness into the back of the factory radio plug, you go to the amp and use the plugs there, I believe the amp is to the right of the glove box? But I dont believe that that would short out the unit.

The facroy amp is to the right of the glove box, and its hard to reach. To connect the avic to the factory harness i am using a harness by metro for amp integrated stereo, it comes with wires to connect the power and RCA cabels for the speakers.

When i installed the speakers, i removed the factory housing for the speakers and I didnt know which wire was the ground and which one was the positive. DO you think it might have to do something with that? I already rechecked all the connections for the avic and all seemed to be fine!! The only thing that i am not sure of is how i used the wires to connect the front speakers.

no reversing the polarity wont cause the deck to do this, especially if its going through an amp. You really SHOULD go to the amp and remove it from the equation, it isnt that hard from what I remember. You may have to extend the wires but well worth it for the sound as I can recall. just do it right.

sounds like alot of work!! after removing the wires from the amp, i just connect them to the unit?

The thing is, i tried to get to the amp a couple times but couldnt figure how to.

you can use a harness. a regular toyota wire harness. of course you have to extend them though. but yes to the deck.

Just did an amp bypass in one of these today. The harness that plugs into the amp is not a standard toyota harness. if you want to get technical it's an isuzu harness but the pinout is different. I think I wrote the colors down at work I'll check tomorrow.

97 cntrylvr? I havent worked on one for a while, but could have sworn the wires where there in a standard plug

cntrylvr79, that would be great man...ill see if i can get more info on the wiring in my car from toyota forum

97 cntrylvr? I havent worked on one for a while, but could have sworn the wires where there in a standard plug

I kidd you not. It was a 97 avalon xls. I wound up replacing the power antenna to and had to run a trigger wire to the new ant because for the life of me and my meter I could not find the factory trigger.

right on, so at least we know its possible. Its been so long since I touched one.

i was thinking of something...What if i installed an after market amplifier and connect it to the deck, would that work? meaning, take the factory amp out of the equation and power the speakers through the amp directly to the deck.

yep, but you would have to get to the speaker wires for that. might as well just run them through the deck.

I will try to do that when its alittle warm around. All I need is some info on how to get to the amp in my car.

YOu'll have to remove the glove box. Involvess a lots of screws and a couple 10mm bolts. By the way I appearantly didn't write down the wiring colors. Sorry.

dont forget about me cntrylvr79 im still waiting for the wiring colors ...not trying to be rude here lol..whenever you get the chance please post the wiring colors...I cant stand looking at my unit sitting next to my computer..i miss it soo much sitting in my dash

hey, you could always test them yourself if cntrylvr is unable to get another one of those vehicles in the shop soon. If you need help with that, just post I am sure we all can direct you in the right way.

Umm.. bold part.

I will try to work on it this weekend. I'll see how far i'll get. Is there something i can use to test which is th ground wire and which one is the postive wire?

yes, a meter.

Hey guys, i know what was the problem, one of the wires got split and it did something to my unit, but no worries, i rewired all the wires again and secured them. And guess what i installed the mediagate MG-25 player in my car and im soo impressed with the quality and how easy it is to use. I will post some pics some time.
