My Firefly is mostly stock, however lots of appearance mods. were done. A bigger alt. was put in to power the Kenwood sound system. 
The windows were tinted Limo black, but the police did not like that haha.
Some mods were tint, headlight covers, bra, wheel covers, pinstriping, and custom decals.
My stero is Kenwood with 14 speaker system. I have 2 4" speakers behind the center concole by my feet, and 4 6" mids in the backseat side panels, 4 1" tweeters, in all corners of the car along with 2 4" in the dash. Along with my 2 10" JVC Subs. All run with the crossover in the console and the two Kenwood amps attached to the back seat.
