Buy a head unit and dash kit...As for the speakers, the fronts, 5 1/4" fit with some force, I dont know the real size thou. And the backs the speakers are 5 inch, But they dont make 5 inch speakers, But you can buy or make brackets to use 4 inch speakers, Or cut the holes to make 5 1/4" speakers fit. Theres plenty of room in the back for subs and amps, So your wallet is really the limit. I use circuit city or crutchfield.com, Bot are good. Circuit citys protection plan is awesome, they just replace it, no questions asked. Problem is, sometimes stuff runs out of stock, so what they do is offer you a) get upgraded replacements and cancel your pro plan or B) keep the plan and pay fpr the upgrades.
