I have yet to see a 2nd gen LS with Nakamichi.
was that option discontinued ?

 

It was up until 2001 they switched to ML. So 2000 was the last year for the Nak.

 

I have a '95 with the Nakamichi. Love it.

 

Mine has the Pio in it, I'd consider the better HU and changer then put better amps off it... provided the preouts are sufficient (>4v).

But I need to find an OEM antenna for the '95-97 cars to replace mine with, the motor died.
