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.
