speaker size

Hello Everyone,
I just recently bought me a new toyota prerunner. I would like to change the speakers in my vehicle. Have anyone upgraded their truck from factory speakers if so please let me know what sizes and brands are the best fit. Oh by the way LOVE my truck.

 

I would recomend you go to www.crutchfield.com and you go to find what fits you car. simply select everything about your car like make model and year and it will tell you what size speakers you need and what size receiver. if you order from them aswell they will send you the required installation equipment like speaker wire connectors so you dont have to solder new connectors on

 

Also on what brands we need to know what your price range is and what kind of music do you listen to.
