Also, can anyone tell me why my tweeters aren't working with my new headunit?

I assume you have aftermarket component speakers hooked up.The tweeters hook to a crossover unit along with the midbass speakers. the Crossover also either hooks directly into your headunit or to an amp.If this is how it is hooked up do the midbass speakers work? Also does your head unit support multiple preamp outs? Nevermind, I see you have a moon and tunes sytem. I know nothing about this setup.
