Navi questions

Hi everyone. We've got a 98 Navi 4wd. Ya, I know. Anyway. Where is the factory amp for the stereo located. Mine's shorting out, and I want to bypass it. Second, what can I do about the factory air ride. My compressor wants to run all the time, and it seems like the back never comes up as high as the front. Any help? Thanks.

THE AMPLIFIER IS EITHER IN THE RIGHT 1/4 PANEL OR IN THE DASH, IN THE CENTER NEXT TO THE GLOVE BOX DOWN UNDERNEATH.

i would get some soapy water and spray the bags and make sure there not dry rotted.
