Sorry for the urgent post but I got my car apart and found out that I am stuck.

I am attempting to convert my amp to a four channel amp following the instructions below that are set forth in another thread on this forum. Following these instructions and got to the point where I have located the amp as well as the four sets of intertwined wires that I am supposed to clip and solder the female rca jacks on. But there lies my confusion

there are a yellow and yellow/brown wires intertwined (2 sets) and a blue and blue/brown set (2 sets). In all this leaves a total of 8 wires. Am I supposed to place a female rca on all 8 wires, or, am I supposed to twist the wires together of each pair of wires that are intertwined together and placing a single female head on the two intertwined wires (meaning you would be only using a total of 4 female RCAs.)

I hope my question makes sense. I do not want to make a big blunder.

Go into the passenger footwell, flip the carpet back, remove the styrofoam (just lifts out), unbolt the metal plate on the floor (this has the factory amp bolted to it..) and then solder on RCA ends to the speaker input wires...


If you go with option1, the new stereo will sound pretty much like the old one... marginally better, and no sub control...

Once you have the amp vilisible, you will see the harnesses that go to it...

Locate the one with "twisted pairs" of wires with the following colours:

Blue and Blue/Brown stripe
Yellow and Yellow/Violet stripe

There will be two pairs of each of these...

Next, unwrap the tape and follow the wires down the harness a little bit... On my car the wires were joined about 6 inches from the amp plug.

When you find this splice point, this is where you can cut the wires, and where you will attach your RCA ends...

If you are good with solder, Purchase some quality (4 total) RCA Female ends at your local stereo shop to solder on here, and buy two RCA cables to run from here to the back of your new deck (6 foot should be long enough, but 10 never hurts) ....

Now that you have located and cut these wire pairs, you will begin with soldering...

Each Blue and Blue/Brown stripe pair and each Yellow and Yellow/Violet stripe pair represents one speaker. Which speaker or subwoofer, ??? you will figure that out after you solder on your RCA's, so don't worry about that...

Yellow is positive (the center pin on the RCA) and Yellow/Violet is negative (outer ring on RCA)

Blue is positive (the center pin on the RCA) and Blue/Brown is negative (outer ring on RCA)

Once you have all of these hooked up, tape up the unused / cut wires on the "deck side" , and plug your new deck in.

 

Is it possible that the yellow and yellow/brown wires you found are the yellow and yellow/violet wires called out in the instructions? If so, then you have found the wires, you just need to follow them back about 6" or so to find where they are joined and install your RCA plugs there. I identified in BOLD that part in the instructions you attached.

Hope that helps.

Thanks so much for the fast reply. But I am afrais I might have already done damage. I located the two sets of yellow combinations and snipped them where they were unraveling, leaving me four separate wires (the yellows) about four or five inches from the amp. I failed to trace the wires back away from the amp to where they join.

Imagine, I now have the four yellows (2 with stripes) cut about 3 or 4 inches from the amp. Since I blew it shall I twist the two wires together and place one RCA female on the end, thus creating two sets of yellows with RCA ends.

I am sorry I failed to follow the initial instructions correctly. Could you please bail me out of this delimma

Thanks

 

You want to do it this way for front and rear.

On the amp.... Pin 7 (yellow) is Front right positive... Pin 10 (yellow) is Right sub positive.... Pin 6 (yellow/Violet) is Front right negative... Pin 9 (yellow/violet) is right sub negative... Pin 1 (Blue) is Left front positive... Pin 8 (Blue) is Left sub positive... Pin 2 (Blue/Brown) is Left front negative..... Pin 3 (Blue/Brown) is Left sub negative...

 

You are ok. You can join the yellow solid's for positive and yellow stripe's for negative.... etc for blue's.... It's the same as doing it before they split. If you want rear control too, do it the way I stated above.

 

From what I am reading, you should be fine.

Each RCA plug will take 2 wires, thus 8 total wires = 4 RCA plugs.

You should solder the solid yellow wire to the center contact of the RCA plug and the striped yellow wire (with the violet) to the outer ring. You should do this twice - once for each set of yellow wires.

Then, you should do the same with the blue & blue/brown wires. Solid blue goes to the center contact and the blue/brown goes to the outer ring.

This will use all eight wires and leave you with 4 female RCA plugs.

If you dont want control over the rear output.... Since you are already there and clipped all of the wires, you may as well run the rear seperate.

 

Just for my peace of mind (and to make sure I understand this), if he ends up with four RCA plugs, he will have separate control of the subs, right? Or is there more he needs to do?

RL

 

Now I am getting somewhere!!

Thanks all for jumping in and bailing me out. I usually mess things up trying to be a "do-it-yourselfer" If it is not step by step I get lost in the obvious.

On that note, one last dumb question. I cut the yellows and you guys have now told me how and where to solder. But do I put the female rcas on the cut wires that are attached to the amp or do the plugs go on part that goes up and thru the body of the car. What I am saying is I have the yellows cut with each one being cut in two. Which side does the plug get soldered on, the cut wire going inti the amp or the other part of the cut wire that is bundled with all of the other wires.

Man, don't you guys flame me yet as I already feel AND AM DUMB, so please be gentle and get me thru this

 

You are putting them on the side that goes to the amp.

 

Thanks SK for the quick reply on that note

Okay, the above interchange between SK and RL has me a little confused. Like RL I thought the way he laid it out would give me separate control over the subs. But SK seems to suggest otherwise, Let me know something so I can give myself the maximum flexibility since I already have everything torn apart

 

Yes, he would end up with 4 RCA's.... 2 Front, 2 Rear. RCA's from the output of the deck are Left and Right with positive and negative in each plug.


If you were to take both yellow wires (solid for positive), as positive on your female RCA and both striped yellow's for negative on the same female RCA... (and do the same on blue) then you will have the same setup as stock but with preamp out instead of normal... Like it states in the other thread, "a little better than stock"..... If you take the layout I gave you earlier and seperate each pin/color then you could have front and rear control through the preamp outputs....

Look at the PDF I attached and read the first post I made.... It is super easy, just take a second to think about it.

I laid out how to get front and rear in my first post on this thread.

 

I see what your saying now LOL. Thats my bad for trying to reply too quickly... You are partially correct in this thinking. The only way it wouldnt work is if he attached the wrong wires together since 2 wires are the same for 2 differnt speakers.

 

OKay, SK I am going to do it your way to get the front and back control. But for a novice your way assumes a lot of knowledge on my behalf. I need guidance for dummies. Being told pins and wires and to figure it out from there after looking at diagrams is simply over my head.

SK since I am following your lead, please give me step by step guidance, if you do not mind. You know I have the 4 yellow wires cut, please tell me what to do from there to get the complete control you reference. Do you want me plugging wires int the amp or what?

Still following SK and RL:

From the above SK are you saying the way RL laid out will give me the separate control over the subs. I am really getting confused now

 

Do you have a cell phone that can receive picture messages? I get off work in 2 hours and can guide you through step by step taking pictures of the amp directly. Just PM me your number and I will give you a call when I get off.

 

I see what you're saying, Josh. SrWilliams needs to make sure that he keeps the "twisted pair" of one yellow & yellow/violet going to the same RCA plug and make sure he doesn't use one "yellow (+)" from one pair and the "yellow/violet (-) from another pair and solder them into the same RCA. Same holds true with the "blue" wires.

Good to note. Now I see why you are calling out the pin numbers for the amp so he can make sure he follows the correct color to the correct pin to make sure he is working on one speaker (a + and a -) at a time.

Thanks for clearing that up!!

RL:

Your followup post helped me also get some clarity in you and SK's communications. From what i gather, I can still follow your approach with the soldering of the wires using the 4 RCAs, provided that I keep the wires straight like you set forth in the above to your communication with SK. I think I am getting this. SO as long as I make sure I use the yellow and mixed yellow from the same twisted grouping and solder them togther on the same RCA plug then I will have the sub control. It is if I take the yellow from one grouping and the mixed yellow from the other twisted set that I then loose my ability to control the subs separately. AM I reading this correctly

 

That is 99% correct. The only thing that is incorrect in your statement is that if you use a yellow from one grouping and a mixed yellow from another grouping you won't necessarily just lose sub control, you will not have ANY sound because you won't have a complete circuit. But to keep this from getting too technical, just suffice it to say that you need to keep the twisted pairs in one RCA to make sure you have proper sound and control. Same rules apply to the blue colored twisted pairs.
