I just bought my first 240sx. I have a 89' 240sx coupe. The previous owner cut the factory connecter. So I had a stock 99-02 infiniti G20 headunit laying around. So I went to the junkyard and cut off the pig tails for the g20 radio and I wired it up to the wires on the s13.

Looks sweet. My only question is that the P11 radio was a Bose unit, meaning it was meant to connect to an amp. Does it have enough power to drive non-amplified speakers?

Well I should have noted I did not wire up the amp trigger. I Couldn't find the amp in the coupe and there was no speakers also. I'm guessing if the s13 is equipped with active speakers and is wired to the amp it would sound better. But for me it sound okay with aftermarket speakers. Its better than nothing lol.
