Radio or no radio

Just wanting to do a poll on what you guys think. I have a (now) 72 Dart Swinger, I have had a radio in and out of the thing. When I got the car it had the factory AM radio but it didnt work. So I installed an aftermarket Pioneer head unit, speakers, and I built a box to install an amp and sub. I was driving my friends car and I somehow broke their deck. So I took mine out, rewired behind the dash (the install place hacked everything up bad) and installed my deck. So I drove it like that for sometime before buying a new deck. Then when the 360 spun a bearing and I wasnt driving it I took it all out and installed everything in my girlfriends car. It sounds alot better because you can actually hear the music over the car. But I am to the point of building my own dash, and I just dont know if I should put on back in it or not. And if not I think there would be alot of space on the dash that didnt have anything there. There is no heater or A/C so all the controls have been removed as well. But I love listening to the exhaust. And I figure if I dont have a radio then I dont really need to install a bunch of sound deadening stuff so I can actually hear it. What do you think?
