[84 400]

Well wehn i bought my truck it had nothing in the dash and nothing behind the seats. the previous owner had a pioneer head unit an amp under the seat and a set of 6x9's in bokes in the corners were the factory ones used to be. I put in a blowpunk head unit and a small box with two round 8's in it. Any ideas on what i should put in it to make it so i can enjoy the tunes? my exhaust is loud and cab drone can be un bearable. i have the stock rear brakets but no speakers. any ideas? links? i still have all the amp wiring but it has no amp

thanks
