you gotta 91-92 right? anything e32/34 up to about 93 outta work around 94 they started with a different smaller amp, the only one to look out for that will plug in and not work right that i 've seen is varly rare, i tried a amp from a 92 750il with the infinity set up but the crossover was way different and the stereo harmonics were strange, about half way home it was making me not feel to good and my head hurt (sound waves can do strange things to your inner ear) no it wasn't that loud! turned the radio off and all got better
all america wants is cold beer warm cat and a place to take a poop with a door on it
