Radio R&R on 2001 Explorer

I get a terrible lot of noise in my radio so I purchased a Noise
Suppressor from J.C. Whitney and now have to figure out how to install
it. I need to access the radio wiring. Can't quite figure out the most
logical way of doing it and don't want to just blindly begin tearing
off dash and console panels. Note that this radio does not have the
four little holes in the front plate to facilitate removal like earlier
models has. Can anyone give me any hints or guidance?
Thanx.
