8 speakers installed, it works perfectly and I'm amazed at the quality of the sound!

Hi Fiodor,
I'm about to start on the same just waiting for my wiring harness. I have the complete C70 Dynaudio 11 speaker, big amp and 901 setup. Before starting I've tried to resolve a few problems - at present my S70 only has 2 x dashboard tweeters, 2 x front door speakers and 2 x rear shelf speakers and none of the Dynaudio speakers are a direct fit. How did you go about your speaker placement? Did you need to fabricate any mounts? Once we start I'm sure there will be more questions, just very pleased to find your thread.
Cheers Peter

I didn't add the speakers because they don't fit in the V70.
Only the rear door speakers are 6.5" on the C70 cabriolet and are a direct fit.
You can build custom mounts using MDF though.

There should be a space available in the stock fuse box for a 30 amp fuse, I believe it is #12, at least that is what number it is in the C70. In my V70 the #1 position isn't being used and the #12 position is for an option my car does not have. You should be able to put the power wires in line with the factory loom to the fuse box then from the fuse box to the under dash connector that connects the dashboard to the fuse box and from there to the amp. that may be way out of the way but it would tidy it up and make it appear somewhat stock. I'm just coming up with this from having taken a C70 apart for these components. I originally was going to place the amp in the rear of the car but am now questioning that as I don't want to have to run the wiring throughout the entire car. Did you fix the Amp in place in any way? Does it get in the way of foot room?

This is a great cheap way to fix loud wheel bearings and engine noises
