Dree Posted November 3, 2010 Report Share Posted November 3, 2010 Hello, I'm about to upgrade my 1996 960-II with an SC-901 headunit, including the Dolby processor. Aside from the four channel setup to and from the separate amplifier, there is a special center channel output on the SC-901. Looks like a 2-way speaker should be connected. My question: what's the pin layout of the connector, and what power is it producing? How much Watts should the speaker be able to handle? Or if anyone has a center speaker plus black grill for sale... Link to comment Share on other sites More sharing options...

And you'll be wanting the stock Volvo speaker. It's purpose designed and built for this dash. Most of all, it's a depth thing. Link to comment Share on other sites More sharing options...
Dree Posted November 4, 2010 Author Report Share Posted November 4, 2010 ... And you'll be wanting the stock Volvo speaker. It's purpose designed and built for this dash. ... Thanks for the picture. I know about the connector, but anyone got a pin layout? To me it looks like a 2-way system. Sounds logical to have one of those Volvo speakers, including black cover, but saw a lot of other brands that sell (2-way) speakers as 'center speaker'. i suppose any speaker can be connected, as long as it sounds good any matches power in-/output. Modified Volvo 'Dolby Surround' grill would look best of course. Modified because my dash is fairly different from C70/XC70 etc.; there never was a 960 born with center speaker I'll place an ad in the 'Wanted' list, but anyone got pin layout?

BEJinFBK Posted November 5, 2010 Report Share Posted November 5, 2010 anyone got pin layout? Blue (pin 5) is positive, White (pin 4) is negative. Beyond that, you'll need to be a little more specific. Link to comment Share on other sites More sharing options...
Dree Posted November 5, 2010 Author Report Share Posted November 5, 2010 Thought there would be a filter build in in the head unit, thus needing separate connectors for low/mid and high, and ground/nefative of course. Is it only signal and ground, so 'full range', to the speaker and is the filter in the speaker? That would be quite easy... Link to comment Share on other sites More sharing options...

A Bi or Tri amped system uses some form of electronic crossover and has a separate amp for each "channel", Lows, Mids, Highs, etc. This system is no where near that complicated. It's just a two way speaker with a cap. A three way speaker would have a woofer, mid and tweeter with a passive crossover As for the Dolby amp's output, it blocks lows and sends mids and highs to the speaker. The mid gets everything, but can't physically reproduce highs, so that's why there's a tweeter. The high pass tweeter cap passes the highs to the tweeter and that's about it. Works Great!

Dree Posted November 5, 2010 Author Report Share Posted November 5, 2010 Clear explanation for me, thanks! So although there is a 5 pin connector for the center speaker, it only uses 2 pins, single amped, filter after connector in speaker. Right?

Dree Posted November 5, 2010 Author Report Share Posted November 5, 2010 RTFM first It's there: 1 x 25W. Although they state 8 ohm. RTFM first It's there: 1 x 25W. Although they state 8 ohm. I mean 4 ohm... Link to comment Share on other sites More sharing options...
crazykn Posted November 6, 2010 Report Share Posted November 6, 2010 If you need to get one of those green 5 pin connectors, go to a junkyard and look for a 90s Honda Civic (preferably 92-96 models). One of the connectors to the dash instruments is this exact 5 pin green connector. At my local pick n pull, parts for civics go fast, so every Civic in the yard is missing its intrument cluster, exposing the connectors, including this one.

I'll have a look around, and if I can't find any, I'll be back with 'a' question :D Link to comment Share on other sites More sharing options...
