Well first your going to want to go down to car toys and ask them to do it for about $20. because more than likley your gonna **** it up. if u insist tho. get an amp wiring kit. the big red wire goes on ur battery to the fuse, make the length of the wire to the fuse as short as possible. make the wire from the fuse(still big red one) go threw the firewall on ur car and all the way to the amp. plug it in. use the manual that came with the amp for this. get the lil blue wire and plug that into ur amp, use manual to find out where. now take that wire (amp trip) and hook it up to the back of ur cd player. then use the grey/black wire and plug it into the amp and then ground it somewhere. basicly just screw it to something metal in ur car. hook speakers up to amp, use manual. toy with amp switches and stuff till it sounds how u want. ur done. this is a real vauge way to do it. there's better/more complicated ways but this'll get the job done. if u can't do it take it to some audio shop they'll for it for like $20.
