Well, when i first got into audio i didnt have a car so i went to wally world and picked up the $20 12" lightning audio, black with lightning audio in gray, and hooked it up to my home theater system which i though kicked *** and i must say did get pretty loud in the house.
My first car setup was a 12" audiobahn( $99) in a 2cuft ported prefab box. I used an old Dual 2ch. amplifier pushing a massive 200rms, but that got me into this hobby and i think i will remeber that longer than most other things in my life.
