Interesting stereo question

[Crashaddict]

So while playing mad scientist converting my ti into the Ti-Rx i had a thought.....Where the hell am i going to put gauges so they look good?
I fell in love with Johnboys setup,but he has the sedan dash. I am now dead-set in putting the gauges in the center stack, however there is clearly not space for them. My question is: is there any way to do a "head unit delete" of sorts and run the speakers directly off my ipod? That way i can put the Boost, Oil and water temp gauges in a place that looks sexy and racy whilst still having some form of entertainment.....any help or suggestions would be awesome
