in some vehicles, the alt upgrade is tough. My Xterra an only support a 190A for $700. I use kinetik batteries and don't have any issues with the STOCK alt.
I use a cig lighter voltmeter for daily from Autozone, $12. stinger makes a nice little one. Tsunami makes one I'll be getting in a few days that's 1/2 din.
as an ex-owner of two Volvos and a '94 940T I know that the volvo systems are tightly integrated and you might check with a local volvo shop to see if changing anything will cause a problem.
