Using a laptop for ypur radio shouldnt be a problem, a little strange but not a problem. I nstalling an amp is easy, you just need a power source which you can get from tapping into the fuse box and finding a spare fuse gap, you`ll need an earthing point which is basically the whole car. Then you`ll need to run spealer cable to you car speakers, obviously, (dont worry about missing the xplod speakers, they are naff) then just connect the speaker out port on your laptop to the input of your amp, depending on the output level of your laptop you`ll need to use either the high level input or low level input. Or you could just buy a car radio that plays MP3 discs which will prbably cost you the same if not less than buying an amp?
