Does an S70 OEM radio amplifier exist?

I have the amp in the void area behind heater core in my car now. It sounds much better and I am no audiophile so it had to be noticeable for me to pick up on it. I'm a country music fan and beer drinkin', cheatin', huntin', luvin', and divorcin' all sound so much more real.
I found it in a car at pick-n-pull.

In my V70 I have 8 speakers, one per door, 2 in the dash corners and 2 in the read door Pillars.
I have a SC900 and I dont have the center speaker in the dash.
If I buy the prologic accesorie, I will have better sound? or its wasting money?
Thanks

There is no
"Pro Logic AccessorY"
What are you referring to?
If you install a Dolby processor without the center speaker, your gains are so minimal it's not worth it, (I know, I did it in anticipation of the rest of the system which I'm doing this week).

The only way to get better sound is to find a dash with a hole in it, (used Dolby dash) buy a center speaker, (then make up the center speaker harness as it's not available anymore) and then upgrade the rest of the speakers

Ok, I mean the Dolby processor.
How can I get the wire color of the two speakers that are in the rear pillar?

That is indeed the 4 x 50w amp that ships with the SC-900/901 decks.
As JRL states, you can just plug and play the Dolby surround unit,
but without the center channel, it's not very useful. It'll just make
your stereo sound hollow and boomy. The center speaker is the key!

Typically if you install the dolby pro logic processor, you cannot have a amplifier behind your radio, because this processor takes its space, and therefore you would have the amplifier under your seat (as the SC-900 and SC-901 do not have a built in amplifier). I upgraded my system to a SC-901 with a dolby processor (got it all off a junkyard C70 for cheap) and bought a whole charcoal dash with the center speaker attached. I've already had a 4 channel aftermarket amp to drive all the speakers in the car at the time. All I have to say is what a difference (dolby pro logic mode)! It moves the sound stage upfront and gives a more realistic feel. This unfortuantely creates a mono effects channel in the rear speakers which I cannot imagine would be great sounding for rear passengers. The original Dolby ProLogic is a rear mono effects channel. The "3CH" mode is what I use when I have rear passengers (keeps a stereo sound going to the rear, but no prologic).

Thanks Kelvin!!
In my country I wont find a dash with the central speaker, so I will stay like this
