Don't buy package stuff.

Or definately buy speakers seperate.

Pick up some old mission speakers, theyll be cheap, but they're wicked

If you're getting speakers you'll need an Amp aswell... Cambridge make decent amps. but they stopped i think. So if you could get one of them off ebay or somehting. then Bad as fuck musac shall follow XD

Or get some multimedia ones.

I don't know much about decks, so you'll have to research that yourself.
