overhead vehicle speakers?
 

I'm interested in buying something like this , but that link doesnt give very much info. I have a 1993 Nissan Pickup King Cab, with one stock speaker:p I want a decent sounding system, but i have a limited budget, I also have an old CD player, but i might upgrade if i can find one for cheap. Any tips? I tried to put my vehicle's info into crutchfield but they dont have Pickup:rolleyes: So I guess I'm just asking advice for what I should get. I want speakers that aren't too expensive, but can put out decent sound, and maybe a CD player with the basic features. Any help appreciated!:D
