I just bought my NSX and all the stereo stuff was stripped out except for the door speakers. I have the stock center speaker and the floor sub/amp on the way and i was told I can only use these with the stock head unit, there is an alpine in there now (POS) and i can not find a stock one anywhere, I finally found someone who has a stock head unit for a 99 nsx...I have a 92. Will that unit work? Thanks so much. Alix
