SeanT Posted June 16, 2014 Report Share Posted June 16, 2014 Bare with me guys, but I'm not a genius when it comes to some of this stuff. But please read this entire thing to understand what I need: I went to the junkyard today and got extremely lucky. A 'new' 2004 C70 came in and it's got some goodies that I'm interested in putting in my S70. It has the center speaker dash and the SC-901 headunit that I want in my car ASAP. First off, I made the mistake of buying an aftermarket headunit which has a terrible FM receiver (JVC KW-HDR81BT). So I was recommended the SC-901 and it has some very cool features that my old SC-816 can't even compete with. But from my understanding, the old SC-816 and my current JVC unit have built in amplifiers to power the stereo system, while the SC-901 does not. So would I need a 4x50 or 4x100 watt amp to install into my S70? If so, I can probably rip it out of the junked C70. (I'm not sure what amps the C70's use) Besides that, I still want the features of listening to music off my phone with the SC-901 headunit. From what I've read, the only two available adapters are the Blitzsafe and the GROM that takes place of the 6-CD changer. Could anyone tell me which is better or which I should buy? I believe only the GROM supports bluetooth correct? Lastly, for the center speaker dash, what must I perform to install this as a working speaker? Does it run into the factory wiring harness on the C70's or does it plug directly into the back of the SC-901 separately? If it's the wiring harness, how could I wire it to the S70 wiring harness? Also, I've read that there is a dolby unit that needs to be in the vehicle to support the center speaker or something. I just would greatly appreciate any clarification on this as I know there is not much information out there on this topic. Thanks in advance.

BlackT5 Posted June 16, 2014 Report Share Posted June 16, 2014 You need the amp under the seat and the wiring harness that runs from the amp to the back of the 901. For the center speaker, there is a two wire harness that goes from the speaker directly to the back of the 901. You need that harness. For the processer, its under the center of the dash in front of the heater core. It connects to the 901 through a din plug. I believe it's physically attached to the precessor so just a matter of pulling it out. Just pulled this stuff out of a 98.. same shit. Amp and amp harness not pictured. Can't help you with the phone adaptors Link to comment Share on other sites More sharing options...
SeanT Posted June 16, 2014 Author Report Share Posted June 16, 2014 Glad I found someone who's actually done this before haha If I'm not mistaken, the amp is under the passenger seat right? And how difficult is it to get the entire amp wiring harness out of the car? Is it matter of just pulling it out from underneath carpet/trim? Also, what does the processor actually do? Thanks.

BEJinFBK Posted June 17, 2014 Report Share Posted June 17, 2014 Not on a C series. That's a whole different ball game. Amp is mounted in the trunk. It could be transplanted into an S/V, but it wouldn't be simple plug and play. I'd snag the HU, Dolby Proccessor, dash and center channel speaker cable and call it good on the C. Then find the under seat 4 x 50 and the cable set in a S or V. That's a pretty easy upgrade. And the processor is what make the center channel work. It also handles the surround effects for the existing speakers. Link to comment Share on other sites More sharing options...
SeanT Posted June 17, 2014 Author Report Share Posted June 17, 2014 Awesome thanks. The junkyard owner said he'd sell the set of Propus (17x.7.5) on it and the center dash with the speaker for $500. Each wheel has a little bit of curb rash but seems possible to buff out. Maybe I can talk him into including the HU, amp and processor too.

MattyXXL Posted June 18, 2014 Report Share Posted June 18, 2014 What yard are you going to in atlanta? $500 is more reseller prices, most yards will charge $32 to $50 for the entire dash and $30 a wheel. I have a C70 amp and a set of 17" nebula reps that Id let go for $250 if you were willing to take a trip down to miami Link to comment Share on other sites More sharing options...
