Over the years I have always had 1 12" woofer (sealed) in my vehicle but my current vehicle the best I can do is 4 - 8" drivers under the rear seat in a ported box.

What should I expect from 4 x 8's (Looking at B2 XM8's) compared to 1 x 12" sealed woofer (in the past were 12W7s)? Will there be less overall volume? Will there be a big difference in low end extension?

Thanks in advance!

I wouldn't be concerned or swayed. That's still a lot of cone area and in a ported enclosure with enough airspace and proper vent area, extension should be maximal for the given subs. A flat alignment is what you should be striving for and 30-39hz is ok with most music genres so if you can at least keep the tuned frequency down in that region while retaining a fairly flat response you'll be fine.

The main advantage is lowered distortion at upper volumes.
