installation is a breeze. However, I need to know your budget and what level of performance you want before I can reccomend speakers.
My usual reccomendation is infinity (you will need the 5.25 for the kick panel, 3.5 for the door, and 4 for the rear). Sound great, esspecially the highs, but lack defined bass. Best if coupled with a sub. The coaxial style run between 55-100 depending on size. The components will run you around 200 per set.
