Seeking advice. I presently use a portable am-fm-cassette in Adeline and thought it would be nice to install a built-in system. Looking for am-fm-mp3 capability. Recommendations? Also, I would like to listen to my VHF on the new speakers rather than through the tiny one on my Standard Horizon. I assume a simple patch cord from the VHF to the input jack on the stereo is all that's needed. Question; if I'm cruising along listening to music or news or whatever, will an incoming vhf transmission be heard? Will it displace the stereo audio or mix with it? Finally speakers. I assume I'll be using boxes. Will I mount them in the upper aft corners? How are they to be attached? The fiberglass is too thin for screws(I think). Velcro? Also, is there such a thing as wireless speakers or must I run speaker wire? I'm hoping someone has already been down this road.
