All you have to do is ...

cut cut cut!

Actually, in my car there seemed to be a 1.75 din hole so I didn't have to cut very much and on the front it doesn't look like there was any cutting at all.

I'm really happy to have a back-up system for when the empeg stays home. Not to mention, when a "guest" comes nto the car with a CD he/she wants to hear, it helps to actually have a CD player.
