speaker wise, ill probably be looking at vibe, JL, JBL, they all seem to be the fairest price for the quality.
as the car only came with front door speakers ill be adding some more.
Upgraing door speakers with standard spaker wires,
adding rear speakers in the form of 6x9's and some small door speakers cut into quarter cards, both powered off two seperate amps.
then eventually a sub of some kind just to give it some bass
