Does the amp turn on?
You can measure audio output from RCA's witha good voltmeter. Low AC range, you should get more than 1 volt when you turn up the volume on your deck.

So, if you have input from RCA's and you've already tested your speaker in another car, and its hooked up correctly, as you say, then you might have a dead amp.

You didn't say what sub or subs you're using and how is it wired?
