Hi there. New to the forum. Been lurking for a while but finally decided to register.
I recently added speakers and a stereo to my 2010 z520. I could not bring myself to drill holes in the fiberglass to house the speakers so I used a piece of 1/4” pvc sheet to fill the space under the step to the front deck. I mounted two 6.5” kicker speakers in the pvc sheet. I mounted a Rockford fosgate stereo in the dash panel to the left of the steering wheel. It works well and now I have some tunes while I’m fishing.
