Unusual audio wiring

[justin0469]

I've had the car for a few months and slowly figuring a few things out that the previous owner decided would be a good idea. Awhile ago, I discover that when he installed the cd player, he just cut the harness off, REALLY far back. I just put it off to his ignorance and go on with it.
As time goes on, I find that the rear speakers have new wiring running to them. I dont see the point, but they work. The dash speakers and drivers door dont. I double checked wiring to the factory wiring and its fine but just gave up for now.
As I finally get the motivation up to remove all the wires goin back to the trunk as well as remove all the paneling and carpet to clean them well (its disgusting really). I find the radio wiring harness sticking out of a bunch of wiring wrapped up in electrical tape under the passengers seat I unwrap it tp find that ALL the wires are cut going to the harness except two red ones. A few of the other wires had been spliced into some aftermarket wiring that was just hangin there in the back. My next step will be to get the wiring diagram for the radio and find out what each wire is and find out what the wires are that are being used. Up until the point of the radio connector being cut it actually looks like its supposed to be there and is coming out from under the center console.

Maybe im just stupid but seems weird to me. In my last eclipse it had the factory amp but the connectors definately dont look like the radio wiring harness.

My question is, why is the radio harness there, whats the purpose of running new speaker wire to just average speakers short of burned up wires and as far as I know, replacement antennas just replace the antenna and motor but do not have new wire for the radio, can I order just the wire from the daelership or does it not unplug from the antenna motor?

wow that sounds pretty crazy, im not sure if i followed it all correctly, could you post some pics? I would just say get a reverse harness and connect it back to where the factory harness would have gone and hardwire all your speakers. just start from scratch. God I hate when people cut the factory harness.

sounds like its time to rewire everything and start over. looks like he cut the stock amp out of the picture.

 

[justin0469]

there was never an amp there, im sure of it, there isnt even any holes in the carpet where it would mount.

here are some pics, can anyone kind of explain whats going on?

well, on my 1g i ran new wires to the front speakers because i custom mounted the 6.5" component set in the doors. i didn't take the time to mess with the stock wiring because there are four front speakers, and two rear. my talon is a DL with NO options. i mean none. the cheapest of the cheap, and only had a radio with a tape deck in the bottom.

i'de imagine that he messed with that wiring because he was unsure how the front speakers are wired. i'm not sure if they are wires in paralell or series. if they are wired in series, then using just one front speaker set wouldn't work, so you'de have to re-wire a little bit. all those stock wires look just like the speaker wire that are in the doors and dash.

i install a lot of stereos in new and old cars alike, and i run into way more problems in the old ones. usually there isn't any harness left at all in them. what i do in those cases is run all new speaker wire to all the speakers, fine a constant 12V supply and connect it to the +BATT wire on the radio, and find a ignintion-switched power source and wire it to the +ACC wire on the radio. The only thing is you kind of have to know what you are connecting to because you don't want to overload the electrical system, so if you don't then it's your best bet to use relays. Then i make a ground for the radio and you are all set. if the vehicle has a power antenna and i can find the wire if there is part of the harness then i wire that to the +ANT wire. if there isn't any power antenna wire that i can find, i simply make a new one by running a wire from the antenna to the +ANT wire on the deck.

Really the only tool you need is a test light.

In your case you have enough of the stock harness left to use the factory +BATT and +ACC wire (and +ANT if you have a power antenna) and then re-run the speaker wires yourself to aftermarket speakers.

In my caprice i have almost completly eliminated all stock wiring alltogether because it's all chopped up, and i've modified the engine so there aren't any emmisions. The only stock wiring left is the headlight circuit, half the turn signal wiring (i made the other half) and the colum harness. Everything else i made.

From my years of experience in car audio/video, he wired up the speakers in either series, or parallel, I can't really see all the wires.

Probably because you have 6 speakers, but only 4 speaker outputs on an aftermarket deck. It happens a lot. I'll bet he didn't check to make sure that he maintained a 4ohm load on each speaker channel on the cd player.

You should get rid of this mess, and start over the right way. Run a wire from each speaker to the cd player, or to the amp you will be using to power them.

Alright, I suppose I will just have to suck it up and run new wires. This is by far the worst pre-owned car I've ever had. So many random stupid unexplained problems.

Does your car have tweeters in the dash? If so I believe you did in fact have the infinty system. What was going on in the picture is the procedure for bypassing the Infinity amp.

Here is the tutorial-

According to that, the left tweeter and the left rear speaker are the same color?

 

[Seano04]

Your GST had a factory amp from infinity. If the previous owner had know anything about car audio he would have gotten a Deawoo wiring harness and and Mitsu one and just bypassed things that way. However, it sounds like he did thinks the hard way. My suggestion is if you want to clean things up wiring wise, you can use the harness under the passanger seat which is where all your speakers are routed. But Power acc. and power constant are found where the radio harness was. Its crazy but if the wiring harnesses are still there...get those 2 harnesses i told you about and re-connect the factory speaker wiring. If you need help with the color codes, let me know and i'll post those too.

It sounds like the easiest thing to do is to just get rid of his mess and just run new wires instead of trying to unscramble his mess. I suppose I will just find some time to do that. Thanks guys for all your help.

If the previous owner had know anything about car audio

I definately know he didn't, along with all the other crap he messed up in the car

 

[snyper1982]

What mess? I can see exactly what is going on there. And yes the tweets are the same color. Only difference between what I did, and what he did was that I actually wanted a fader control, so I have 4 sets of wires instead of 2, ran the door panel and tweets off the front, and I threw a capacitor inline with the tweet to keep from blowing it.

Really wish I had known about the bypass harnesses when I was putting my deck in, oh well, it wasnt all that hard anyways. Just time consuming.

 

[justin0469]

Just time consuming.

I suppose thats what I mean. It would be just as fast and less complicated to run new wires not to mention more organized. Why do the front tweeters run off the rear speakers?

What I think I may do when I get around to it is just get a component system with a crossover and run all new wires. Might as well do it right and do it once when you do it.

Sounds like a good plan. The tweets dont run off the rears, they are just same color. Confusing at first I know. I plan on running all new wires as well. But I also plan on running an active x-over, and multiple amps. What component set you looking at? CDT is highly praised, and can be had at a good price. CL-61a. Check out woofersetc.com. I have never heard them so I cannot say for certain how they sound, but I am sure they sound much better than stock.

 

[justin0469]

I'm not into the system stuff, so I am just looking for something thats not too expensive but good quality, clear highs and good and deep bass response. So just looking real fast, the Boston Acoustics SX50 look like what I might go with. MSRP is 250 but I've found them for about 130.
