Re: Replace rear deck speakers on 850 850 95



Gee, just did it last Friday, in a 95 too!

I used Infinity Kappa 6x9's, there is a photo and review (not by me) of these speakers at http://www.volvospeed.com/Reviews/kappa.htm

There is no drop in replacement that I know of. I don't know exactly what size the originals are but it is not a standard size.

Installation option 1:

Remove old speakers, held on by 4 screws sticking out the bottom of the speaker enclosure into the trunk. Can't miss it. The speakers are kind of stuck in place, probably have to bump them to get 'em to come loose. Hop in the back seat and unplug the wires and the old ones are gone.

I chose to flush mount the speakers. That meant enlarging the holes in the metal deck. I made them about 1/2 inch bigger on the front side of the hole (toward the front of the car). That's a slow job. I used a dremel tool and cutting wheel, still took me a couple hours lying in the trunk (I'm slow). On the first one I cut it a little bigger and a little bigger to get the right size, but it was better than going fast and cutting too big!

The infinity's come with a spacer ring that's around an inch tall, it goes between the speaker and the rear deck if they don't sit all the way down (they don't). I think if you choose not to use the spacer you have to cut the deck material (the soft stuff). I didn't want to do that, there would be no way to undo it.

You have to drill new holes to screw in the speakers and you need to get longer screws. I got 3" long bolts about the same diameter as the ones that come with the speaker. To get the new screw holes in the right place, I

- put masking tape around where I thought the holes should be

- put the speakers in place

- used an ink pen refill to mark through the speaker's screw holes onto the tape.

It doesn't have to be exact but get as close as possible. I was only able to put in 3 new screws, the 4th (outboard front I think it was) ended up on a multilayer metal part that I didn't feel like drilling through.

Details: There is a big round black thing glued/wire tied on the side of the speakers. That prevented them from sitting down in the newly enlarged hole in the deck. I cut the wire tie and moved that thing gently to the side. The new speakers don't quite cover the hole left by the originals. You have to look through the rear window to see that, but it is not a "perfect" fit. However it looks ok and sounds great.

It took me the better part of a day to do this. I had to go buy a dremel tool and make a couple trips for various wire connectors, and I wasn't in a hurry.

Installation option 2:

Have it done by a sound shop. They have the tools and experience, and if they screw up it's their problem not yours. (I got this advice offline).

These new speakers and apparently all new ones are 4 ohm, the Volvo ones are 8 ohm. There was recently a discussion on this board about how you shouldn't switch them. There may be an electrical reason why you shouldn't but it works for me. Maybe at high volume the 4 ohm pull too many amps than 8 ohm. I don't turn mine up all the way so hopefully not an issue.

The new ones sound much better than the factory stuff.

I think Prospero has a thread on swedespeed about installing 6x9's, he and a couple other people gave me some clues offline.
