Great Price! Came free with Head Unit Purchase

The Nissan Bose systems come with a regulator, if you use this adapter without the regulator for the subwoofer it will be much louder on the lower volume settings (not a big deal). Also, Nissans DO NOT ground through the black wire on this adapter you have to ground to the car. I just used one of the metal screws that attaches the radio bezel to the metal frame.

Scosche NN03B/NN03

Great product (Scosche NN03B/NN0E), installed in 2004 FX35 with bose, the stereo is the Clarion NZ501. Connector worked perfect. The package of the connecter said not to be used with amplifier systems but it worked and had the blue and white amp trigger wire and amp ground. System sounds better than before and much louder and clearer.
