I finished putting my Alpine deck in and the antenna does not come up at all, I hooked up the power ant wire and pluged in the ant, but when I first turned it on the ant went up but now it does nothing, im not new at putting in decks... like my 7th or so, any help thanx

 

first, recheck the connection, then take a voltage meter and see if the antena wire is pitting out current. If it does and the antenna doesn't go up, there's something wrong with the antenna motor.

 

Go to Best Buy or Circuit City and buy an adapter for about 10 bucks or so. Nissan's power antenna doesn't automatically work with all aftermarket stereos. The adapter plugs between the new radio and the antenna wire and everything works fine after that.
