Guest Guest_850 Stylzz Posted March 25, 2004 Report Share Posted March 25, 2004 Ok, it looks like my previous post has fallen into oblivion, so here goes again...I started out with what I thought would be a rather modest car stereo upgrade. I decided to go with a new Head Unit and some new speakers for the doors and dash. All went great until I realized that the HU would only run the 4 door speakers. Crap. Oh well, so now I am buying an amp. I bought it in hopes of runiing all 8. But now, I was concerned that with a 4 channel amp, and my having to run 4 channels in parallel of 2 speakers each that me rear loads would be 2.66 and my fronts @ 2. So I was off to buy a set of rear speakers to even out the resistance load.For those of you who found that last part a little bit confusing, I bought a 4 channel amp, and therefore can run a max of 4 different signals, not enough for each speaker to have its own dedicated channel. SO in order to preserve the stereo effect, I have decided to run my wires in 4 pairs of 2 speakers wirred in parallel. THose groups will be 1. FR door FR dash 2. FL door, FL dash 3. RR door, RR deck 4. LR door, LR deck.Now comes the hard part. Im now going have to run speaker wires from the amp to the original speaker leads that came from the deck. I'll have to connect them according to what I had lais out before as my pairings. Now what I had hoped to do was splice into the Metra wiring harness that I bought to do my HU upgrade. But counting wires, it seems that the Metra wiring harness only has 8, which leads me to believe that this harness only runs to those 4 aforementioned door speakers. If that is the case, I will have to splice into the original wiring harness as supplied by Volvo. I really didn't want to do that as 1. it will be a pita (a comple and b. I dont know what each wire controls) and 2. My install will be pretty much irreversible. Also something I didn't want to have happen. Does that sound like what Im going to have to do? If I am missing anything, please let me know. All help is appreciated *cough* BING *cough* Link to comment Share on other sites More sharing options...
steve s Posted March 25, 2004 Report Share Posted March 25, 2004 y not run ur own wires for all the speakers from the amp...except the front door (i don't really know how to get past that socket)...volvo hu has two harnesses...the speakers are split between the two... darn..the forum used to have a layout of what each one was...i'll have to get home to find it again...

AnthonyR Posted March 25, 2004 Report Share Posted March 25, 2004 Just a note, the corner speakers (ie: FL door and dash, RR door and deck, and so on) are already parralleled in the cars wiring harness, no need to run them yourself if you are simply tapping into the metra harness. Just tap into the four corners and you will be fine. I wouldn't be too worried about different ohm loads, shouldn't make a bit of difference to a quality amp.

Jozone Posted March 26, 2004 Report Share Posted March 26, 2004 how many watts can the stock wiring handle? Link to comment Share on other sites More sharing options...
850 Stylzz Posted March 26, 2004 Author Report Share Posted March 26, 2004 how many watts can the stock wiring handle?Well more that I think anyone (especially me) would push. I had originally wanted to run new wire direct to each speaker, but gave that idea up pretty quickly. :) Link to comment Share on other sites More sharing options...
AnthonyR Posted March 26, 2004 Report Share Posted March 26, 2004 Unless you had a factory amp, all 8 speakers should work with the aftermarket deck using the Metra harness. Unless something else wierd is up, cause if you think about it, if you didn't have an amp and it was all off of lets say an SC-811, where else would the other speakers be hooked to? There is no other place. Link to comment Share on other sites More sharing options...

There is no other place.If only that were the case. I would much prefer it. ANd hopefully Im missing something, but I dont think so. Here's how I reason:On whether or not I have a factory amp:I have a 95 GLT. As far as I know, none of the GLTs came with an amp, only the R. Lets assume for a second that that's wrong and maybe mine did. Well, after I installed the aftermarket HU, I did play music for a while, before I decided to go nuts and upgrade everything. If I had an amp, I believe I should have heard some distortion through the 4 working speakers. I did not. Those two reasons leead me to believe that I dont have an amp.On the wiring harness:The Head Unit I bought was a Panasonic DF602U. I bought it b/c A. It looks nice and B. It has connectivity galore and C. It was reasonably priced. When I purchased it, I went to Best Buy to get what I needed, including a metra wiring harness. WHen I spliced and crimped the wires from the Panasonic harness to the metra, the wires joined up 1 for 1. Nothing extra and unpaired or hanging loose. Therefore, all the signals generated by the head unit were sent along a metra wire, leaving nothing unused. Now, assuming that the Volvo harness mated 1 for 1 with the metra harness, the volvo harness should also receive a signal across every wire. When I was hooked up, I heard sound out of only the door speakers, leaving me to believe that only 4 channels were being sent a signal. COnclusion being that the metra does not supply access to all 8 of the Volvo speaker channels.I guess the logical explanation is that the metra harness itself only mates to 4 channels on the Volvo harness.PLease, someone correct me if I am wrong. Unfortunately for me, I dont think I am. Link to comment Share on other sites More sharing options...
steve s Posted March 26, 2004 Report Share Posted March 26, 2004 these are the two volvo harnessesthe front dash speakers are run off the larger harness... and the rest of the 6 speakers are run off the smaller harness..1A = Dash Left Speaker +, 2A = Dash Left Speaker -,7A = Dash Right Speaker +, 8A = Dash Right Speaker -,1B = Left Rear Speaker -, 2B = Left Rear Speaker +,3B = Left Front Door Speaker -, 4B = Left Front Door Speaker +,5B = Right Rear Speaker -, 6B = Right Rear Speaker +,9B = Right Front Door Speaker -, 10B = Right Front Door Speaker +.anyway...quick fix....go borrow and volt meter... connect the metra harness to the volvo harness, but not the aftermarket head unit.... touch the leads on the speaker wires and the pins on the metra harness (hu side)...

Guest Guest_850 Stylzz Posted April 3, 2004 Report Share Posted April 3, 2004 Ok, I am at the present moment confused out of my gord. Steve, thanks so much for that last post, it was awesome. But then it confused the crap out of me. There seems to be a pair of speakers missing from that list--the left and right rear doors. Well, I figured that it should be easy enough to figure out. The wires to the dash speakers matched with the wires that ran from the harness, so it should be simple. I pulled both rear door speakers, and they BOTH seemed to be brown wires. One with a white stripe and one with a black stripe to each. (I have no idea which one is + and which is -)Now comes the baffler. There is only 1 pair of brown wires, and if what steve said was correct, they belong to the left rear deck. Here's the oddest part though. Just driving with the headunit, connected through the Metra harness, the rear doors receive a signal. So which wires behind the volvo harness do they belong to?

550 Posted April 3, 2004 Report Share Posted April 3, 2004 THe read deck and the rear door should be paired together. Maybe in the harness I'm not positive, but the info on that picture tells it all. It may also be parallel with the rear door. To clarify that I mean the rear door could have a wire going to the rear deck, I'm not sure if you checked for that yet. Also here is the link where that diagram came from http://volvospeed.com/Repair/radiocon.htm. It pretty much says what I tried to say, but it says it alot clearer. Good luck. I have to do my s70 soon it has 8 speakers too, so it should be a trip Link to comment Share on other sites More sharing options...
Hum Jim Posted April 4, 2004 Report Share Posted April 4, 2004 My rear door speakers are dead and I've been looking to find out where they join the rear deck speakers. Any clues? Link to comment Share on other sites More sharing options...
steve s Posted April 4, 2004 Report Share Posted April 4, 2004 yeah, i got that from this site...used it to wire the front door speakers...socket too complicated for me to add wire too...There seems to be a pair of speakers missing from that list--the left and right rear doors. Well, I figured that it should be easy enough to figure out. The wires to the dash speakers matched with the wires that ran from the harness, so it should be simple. I pulled both rear door speakers, and they BOTH seemed to be brown wires. One with a white stripe and one with a black stripe to each.

Here's the oddest part though. Just driving with the headunit, connected through the Metra harness, the rear doors receive a signal. So which wires behind the volvo harness do they belong to?1A = Dash Left Speaker + red/white, 2A = Dash Left Speaker - yellow/white,7A = Dash Right Speaker + yellow/grey, 8A = Dash Right Speaker - grey3B = Left Front Door Speaker - green/brown,4B = Left Front Door Speaker + green/white,9B = Right Front Door Speaker - red/black,10B = Right Front Door Speaker + red/white,1B = Left Rear Speaker - brown/black,2B = Left Rear Speaker + brown/white,5B = Right Rear Speaker - pink/black,6B = Right Rear Speaker + pink/white,according to the website, the rear door and rear deck are wired parallel... so i don't know the actualy where it is split...r u sure there isn't a pair of pink wires for the right rear speakers (door and deck)?anyway,gosh...i wish i had a visual of the metra harness... have u tried the stock speakers with the new hu u have? i mean, have u hooked up the harness to the new aftermarket hu and left the stock speakers in to c if u get any sound from the front door & front dash (the rears are parallel so it doesn't matter if u hear one as they come out of the same source so if u hear rear door u should hear the rear deck)? and try the head unit's balance to see if u change the sound front/rear/left/right that they are indeed the correct corners? if that is true, then it'd be like anthony said, and be very simple... the 4 channel amp would be easy... 1) front right 2) front left 3) rear right 4) rear left.... all u have to do is wire up speaker wires from the amp to the metra harness... a volt meter would tell u which amp speaker wire would go to which wire in the metra harness...and the mtera harness obviously goes to the volvo wiring..u'd be set...
