how much is a audio package for a car with 2 ten inch subs cost?

uh dude.. you gotta be more specific.. first of all.. this package you speak of, what does it consist of? You goin all out with speakers, deck, subs, amp, cooling kit for the amp.. is it integrated to where your music doesn't stop til the doors close? what brand are you lookin at? you want better hi's or low's or mid's or what? There are a lot of options when you're talking about makin your music sound killer.

The best thing you do is go to your local audio store like best buy or circuit city and talk to the dudes in the sound room. they are cool. they'll hook you up with free install too.
