[audio] dumb ohm-age question (or square peg & round hole)

[foxxinabox at wideopenwest.com (Foxx (in a box))]

   okay, so now i've two sets of bose speakers laying around for a 
custom built box. i've also a 250w, 4-ohm amp waiting for a home. i have 
been, thus far, unable to determine the ohms of the speakers, though i 
have had one place said that most likely are 2-ohm, but might be 4-ohm 
(lotta help, that one). they are out of a porsche (no bose amp present 
for those) and an audi (which the bose amp was there, but no markings on 
it). anyone know what ohms these are or any way that i can find out? 
also, and here's the dumb question, is there any way to make 2-ohm 
speakers work with a 4-ohm amp? i'd assume it'd just blow the speakers 
or there'd be one universal amp. and help would be appreciated. thanx.
