Hi, I have a 1992 300ZXTT which originally had a Bose system. Someone replaced the factory bose stereo with an Alpine unit. I need to replace the speakers. I understand you can buy factory Nissan speaker brackets so you can install non bose speakers. My question is on the speaker wiring. The bose units have an electrical connector with 4 wires that go to the speaker box. The 4 wires go to the amplifier inside speaker box and then 2 wires come out of the amplifier and go to the bose speakers. When you use the speaker brackets for non bose speakers the amplifiers are eliminated. So how do I hook up the speaker wires?
