Installing Amp/sub


Angelus09

Recommended Posts

Hello Everyone,

I am about to undertake the project of installing an aftermarket amp and subwoofer into my 1997 Volvo 960. However, I am not planning on changing the head unit (at the moment, maybe time will tell later), which brings up a few problems. The radio, as you all know, has the DIN 6 Pin connector linked to an amplifier. I will be constructing the adapter cable (http://volvospeed.com/vs_forum/index.php?showtopic=39067&hl=) so I can connect my aftermarket amp to the radio, however, I am guessing this will cut all my other speakers, which would be hooked to the stock Volvo amp (correct me if I am wrong). So my question is, how would I construct an adapter cable that would have a pass-through DIN connector so I can link both my aftermarket amp and the volvo stock amp?

Also, any advice on routing cables from the radio to the aftermarket amp would be helpful.

Thanks!

So, I'm guessing this is essentially what Crasnkn has built, but with female DIN-6 plug spliced in?

And do I have to worry about the second half of that drawing?

*crazykn ...typo

No, it's a factory amp cable with 2 RCA's spliced in - you don't cut the DIN off the cable...

The harness was for using a Volvo 4-channel amp with an SC-816 without cutting the factory harness.

Err. yeah, that's what I meant...

Do you know where I could buy that factory cable?

And I did look into the line converter option, but how would I wire that in?

Well, I later discovered that my amp has a high level input connection, where I can connect it directly from my rear speakers., however, I can even seem to find where the speaker terminals are.... all the wiring is hidden... any ideas?

Also, there seem to be absolutely no holes to route wires from the engine compartment through the firewall to the main cabin. Does anyone know how I could do this in a Volvo 960? Thanks.

Not sure about the 960, but in the 850s you have to unscrew the speaker covers from inside the trunk, then pull the speakers up from inside the cabin. From there, I imagine there would be some way to extend some wiring down to the trunk.

As far as a firewall hole, drill your own! Be sure to use a plastic grommet to protect the wire.

The hole going through firewall is on passenger side. You will see a bunch of other wires as well. Fair warning, its a real oh yeah! getting that thick wire through there. I'll try to remember to get you a pic. Run cable up the passenger side to back seat (will need to remove). There is a hole that you can run cable straight back to the trunk.

Did you ever find that picture?

I faced the same Problem... Easy way to go: buy a new radio or buy a predone adapter (there is a site selling them, just search a little bit on the forum)

Hard way: solder the thing your own. That's what i wanted to do first, but i ended with a new radio, because i wanted an iphone-connector.

Good Lock with the install!
