Tony,
Sure it can. See my previous post about rushing my crossover install and snapping off the circuit board...

Actually, it really can be done. I'll just have to take a long lunch, but I figure I can take my dash apart (including removing the current stereo) in about 3 minutes (it's three 7mm bolts, two wiring connectors, and two more 7mm bolts total.)

I wouldn't dream of rushing it. Since I generally get to work 30 minutes early and leave anywhere from 1 to 3 hours late, I can have a bit extra at lunch if I ask nicely.
