P80 Dolby Stereo Amplifier Wiring

Documentation for P80 Dolby Stereo Amplifier Wiring

This is pretty self-explanatory: it’s a downloadable PDF of the stereo amplifier wiring for Dolby equipped P80 Volvos.

MVS Contributor Neil adds:

To all intents, the amp is just on a wiring loop that connects to the original 2 connector that plug into the regular radio, runs to the amp and then returns. I’m not familiar with the Dolby system, but I think it is a processor but not sure of the amp capability. You do need a amp for all that system to run. Can’t recall the product name but there is an aftermarket unit you can plug into the head unit that gives blue tooth capability.

Two-Category Search is Here!



Why does this exist? With almost 1600 entries in the Volvo Repair Database, finding what you need is growing harder as the Volvo Repair Database (VRD) grows. For branding, I named it Powersearch, because it’s a manly, tough name with “power” in it that makes you think of 5000hp top-fuel dragsters, ten-ton bulldozers and jet fighters.


Say you own a Volvo 850 and need to know what strut mounts to buy and how to install them. If you’ve browsed the VRD for 850 entries (651) looking for suspension fixes (130), you’ve spent considerable time looking at stuff not specific to you.

This Powersearch tool crosses the 850 category with the Suspension category, to show you the suspension VRD entries (58) that are relevant to you as an 850 owner.

So now we have a tool that finds repairs that exist in two categories.

Who Knows What This Will Turn Up

We’re not limited to crossing a Volvo model with another category, interestingly. We can cross say MPG with Emissions (4) to locate entries tagged with both those categories. Any two different categories are ok to search.

Please try it and let me know what you think. I’ll be adding it to the site navigation in the coming days. Also note it’s not released for mobile yet. Soon.

P2 Seat’s Leather Lasts Longer Than P80


Not anyone’s seat. Just an image I found, used for illustration only.

This post got me thinking about seat leather. Sleddriver:

My front seat leather is pathetic. Even using Lexol on a regular basis didn’t help.

Let that sink in. Even with care*, the leather failed.

Mine too. I used “Eagle” brand (automotive) leather conditioner for years starting when I got my 850 in the summer of 2000. My 850’s drivers seat is a wreck of split leather (graphite) and exposed foam.

Volvo C30 Review

Volvo C30

Since the Volvo C30 production ended about four years ago, the C30 activity here on MVS Volvo Forums has increased, naturally, due to C30s getting older and needing repairs.

Here’s a nice summary and review of the Volvo C30 — broken into driving impressions, handling, and interior — by MVS Contributor Volvo4251:
