Help quick :)

Okay so i need someone to sort me out. i dont understand electrics and ICE at all
basically im not even that interested in sound quality i just want a nice looking clean boot build and some heavy bass!

i want a JL Audio Amp Monoblock A1200 and one JL audio sub in the back.
but after that im under a tight budget. i dont really want to get rid of the stock headunit would i be able to wire the parts i want up to the stock grande punto headunit?
and is it VITAL to get new door speakers or will the stock ones hold out?

need a quick reply! first person with decent answers can be my friend (NO HOMO)

gp door speakers are pretty good if you've got a sub adjust your stereo to run as little bass as possible through the speakers and they'll sound even better.

As for the stereo, yes there is a way to wire it in but for the cost of a basic stereo with one pre amp output its really not worth the effort.
