I would have to say a kenwood headunit, infinity 6x9 infinity sub and fusio amp or somethink like that and some little fusio speakers for the front
Its not that hard, im only 14 nearly 15 and i know how to fit speakers, amps subs ect.. (No im not a yob) my dad has it in his car and that and shows me how to do stuff ect.. so its really not hard on the door cards undo the srews take off undo the srews on the speaker then the wire's put the other ones in the pop the door card back on, amp and sub you have to get the main wire route it from the battery into the car and up to the boot ect.. then for the 6x9's you have to cut the parcel shelf then srew them in and connect to the amp, headunit you take the old one out with the tool they give you unclip the connecter and hoply if your not unlucky it will go straight in without any fus (on my mums i had to redo all the wire's) connect the amp wire to it and all the other wires and then slip it back in, then attach the main amp cable to the battery.
