5.25" Speakers/Amp--Oddball Question...

I'm in the midst of a project to build an arcade cabinet MAME machine--MAME is a computer program that uses copies of the ROMs from old video games to emulate them. So, with a generic control console, you can play any of about 4,000 different pre-1995 games like Pac-Man, Galaga, etc. reproduced with a fair amount of exactitude...

Anyway, the prefab cabinet I'm using calls for a pair of overhead 5.25" speakers--audio would be fed out of a computer. Trying to think of the best way of getting decent sound, and would appreciate any input, even tho' this is far from audiophile... Here's the pro's and con's of what I've been looking at:

1. Computer speakers. Easy connection and video shielded, but sucky quality-wise. Also generally in enclosures that are incompatible with 5.25" cut-outs. You can find sets with remote volume knobs, which would be a good thing.

2. Car audio speakers. Probably highest quality-wise. Would require a car amp, which means building a quick 12V regulated power supply, but that isn't too tough. Presuming remote volume knob could be rigged with a dual gang potentiometer.

3. Buying component drivers. Unsure here... Parts Express sells some shielded drivers that would fit, but they fall into the bass/midbass category (only seems to be one "full range" coaxial jobbie, but comes w/o a crossover). I'm not real tempted to build an xover. Also unsure here whether I'd need to do extensive cabinetry to build a closed box for the drivers. Also need an amp to drive them...

Any other ideas/suggestions? Guess my present inclination is to go car audio, but I do have some worries about the lack of video shielding. The speakers are mebbe 2' away from a 27" monitor that I really don't want to mess up--this old school 15 kHz monitor didn't come cheap...
