This is what I've got in the EG Civic...
Its not much - But it puts a fair few to shame
MUAHAHAHAHA
*Alpine 'I don't Know' Head - The one with the ipod connector
*Kenwood 640W Amp - More than enough power
*Alpine TypeR 12inch Subwoofer in box - Doof Doof
*JL Audio Tweeters - THESE THINGS SCREAM!!!!
*JL Audio 6inch Rear Speakers - Extremely Clear Guys!!!
*Pioneer Front speakers... - Couldn't afford anything more after buying the above...
Thinking of putting in a separate battery in the boot or somewhere for the doof and neons
