Seeing some of the threads on here im guessing you can get new head units for the RX-8, how easy is it to take out the existing 1 or is it possible to hook up subs and amps to the existing one?

I got a big ice install planned, i just dont want to rip anything out and realise i should have never have done that.

 

Sorry to state the obvious... but did you realize there's a search button in this forum? Really... your questions are so generic, it is certain that everything you're asking was covered at great lengths.
