--Aaron-- Posted July 3, 2011 Report Share Posted July 3, 2011 I found this: http://volvospeed.co...post__p__486355 Everything else really didn't have much helpful information. That diagram really makes my eyes hurt. I'm looking to find the rear deck speaker wiring information for my car. I need it to install a line/level converter. Apparently on the trunk side of the rear deck speakers there is no wiring showing so I'm assuming the rear deck speakers' wire is under the rear deck cover which I do not feel like removing. The plan is to install the line/level converter behind the radio to the rear deck speaker wires so that my subwoofer will fade with the rear. Unless maybe the rear deck speaker's wiring runs down toward the seating area? I can pick it up where ever I suppose, I just don't want to end up taking an overkill amount of things apart. Thanks in advance. Link to comment Share on other sites More sharing options...
BEJinFBK Posted July 3, 2011 Report Share Posted July 3, 2011 That's only one of the pages in the diagram book. But at MVS, you can download the whole thing. ( Thanks, Matt! ) You'll find the other pages, including component locations cabling pinouts and cable routing available here: http://www.matthewsvolvosite.com/volvo-wiring-diagrams/ at this link: http://www.matthewsv...0_C70_Coupe.pdf Manual pages ( PDF Pg # ): 184 ( 66 ), 185 ( 243 ), 82 ( 184 ) and 47 ( 151 ) should give you all you need for tapping in. Be advised, the pages are a bit out of order... Link to comment Share on other sites More sharing options...
--Aaron-- Posted July 3, 2011 Author Report Share Posted July 3, 2011 Thanks for the links! Is it just my computer being slow....the pages come up blank and lag the stuff out of my browser. Edit: Nevermind, just my computer being slow. Link to comment Share on other sites More sharing options...
bdimag Posted July 3, 2011 Report Share Posted July 3, 2011 if you do that, do you expect your rear speakers to work? are you sure your amp doesn't have speaker level inputs? if you can't find the wiring near the rear speakers... how do you expect to wire the amp?

--Aaron-- Posted July 3, 2011 Author Report Share Posted July 3, 2011 I'm really sorry but I don't understand those schematics really. Would you mind translating for me? I think the speakers shown closest to the CD unit are the rear speakers which do give color breakdowns. Does that breakdown show where the rear deck speaker wires route from the speakers? Actually, I could probably just look for the rear deck speakers by the color behind my radio instead. Either way works. I do have a V70R amplifier. The line/level converter I got accepts the wattage that the amplifier puts out so we're good there. It's a PAC something something. I'm probably going to need my hand held here, schematics are not familiar to me at all. I really appreciate it. Link to comment Share on other sites More sharing options...

Yep, I'm just going to tie into them. I did the same thing in my wife's car, just T off the wires I needed. Her's were just easier to find because of it being a cheaply built GM. I'm positive the amplifier does not: It does have signal sensing turn on to eliminate running a remote wire though. Which I do not plan on using, I want it to have a solid remote source. I will find the rear speaker wires at the radio, wire in my converter, run my RCA's back the passenger side, opposite the side where the 4 AWG power wire will run.

bdimag Posted July 3, 2011 Report Share Posted July 3, 2011 yea i thought about that after I posted... i dunno I personally would rather find them at the rear then run a wire all the way back. do you already have the RCA? may be cheaper to run speaker wire to the rear... might also be better to have the converter more accessible near the amp (will it even fit behind the radio?). also this excerpt from the manual may change a few things: IMPORTANT! The sensitivity of the signal sensing turn-on circuit has been designed for high-level (speaker level) signals, not for low-level (preamp level) signals. Using this feature with low-level (preamp level) signals is not recommended. We do not recommend this method of turning the amplifier on and off as a default. Whenever possible, use the conventional remote turn-on lead method. http://mobile.jlaudio.com/pdfs/Slash_amps/500_1_MAN.pdf Link to comment Share on other sites More sharing options...

I already ordered Tsunami 12 ft. RCA's. I stayed with a longer length to be safe. The converter doesn't have to be accessable, it is not an adjustable one. I sort of want to just hide it in the heater core area and run the RCA's from there.... Yeah, I read that. I'm using a solid remote source, no worries. I've been reading and reading that manual learning about all the amplifier's adjustments. :lol: Link to comment Share on other sites More sharing options...
bdimag Posted July 3, 2011 Report Share Posted July 3, 2011 alright lol -- i'm just saying you could skip the the remote wire and definately the speaker/line level converter.... Link to comment Share on other sites More sharing options...
--Aaron-- Posted July 3, 2011 Author Report Share Posted July 3, 2011 Ok, I'm starting to make sense of that schematic. It looks like 16/17 and 16/18 are my rear deck speakers. Now to figure out what damn color they are at the radio harness. alright lol -- i'm just saying you could skip the the remote wire and definately the speaker/line level converter.... I see what you're saying, I just don't think the signal sensing turn on is a very dependable constant voltage to tell the amp to stay on. I've always been a fan of straight to an ignition source for the remote connection. I cannot skip the line level converter, not with the amp not having speaker level inputs and the stock radio having no existing RCA outputs. Unless we're not on the same page about something... Ok, I'm starting to make sense of that schematic. It looks like 16/17 and 16/18 are my rear deck speakers. Now to figure out what damn color they are at the radio harness. Alright, it looks like I need B5, B6 for the right and B1, B2 for the left. Can someone who understands what their looking at confirm? :lol: Link to comment Share on other sites More sharing options...

That statement says don't use the auto turn on unless you're using speaker level inputs... so... if that amp has auto turn on, it has speaker level inputs... also, in that manual, just to the right of that paragraph (page 7) under AMPLIFIER INPUT SECTION, you see a picture showing RCA inputs and a switch above that says INPUT VOLTAGE - LOW/HIGH. it has speaker level input using the RCA inputs (this is how my pioneer is setup)... If I can find them, you can have the wires from my pioneer amp -- I wont be using them... or just get them from radioshack or online... Link to comment Share on other sites More sharing options...
--Aaron-- Posted July 3, 2011 Author Report Share Posted July 3, 2011 Alright, double check me here: Left Rear: B1 - Negative - Brown w/ Black stripe B2 - Positive - Brown w/ White stripe Right Rear: B5 - Negative - Purple w/ White stripe B6 - Positive - Purple w/ Black stripe If these are correct will they be the same color where they connect to my stock wiring harness from my V70R amp harness? we're not i guess...

So you're saying that when the amplifier was in it's BNIB state it probably had a cable similar to the one in your picture to use in place of RCA to RCA?

--Aaron-- Posted July 3, 2011 Author Report Share Posted July 3, 2011 yep found em. Hmm, that converter is a pretty good quality unit. I'm wondering if it'd hurt to use it with the RCA's I bought. Maybe I'll shoot JL an email and ask. If that's even possible. I mean, it seems like it'd still be the same signal using a cable like yours or a converter/RCA's.
