My current audio system is a Kenwood 309S with a dead cassette player and with factory speakers and amplifier. I'm contemplating purchasing an oem Bose cd, cassette and radio system made for the 94 Maxima or at least a Bose system that will fit the opening. Can someone tell me all what might be involved to installing the Bose system i.e. speaker requirements, wiring, etc. etc....thanks in advance for your assistance:)
