Im looking into getting a system out into my car.Its a 97 chevy blazer.the only factory speaker speaker that works is the driver side one.I have 1 sub that is a sony i believe.i don’t know the amp wattage but its a 10 inch.i need to know what size speakers i should get and if i should get another sub.I was alson wondering if i should get a box to fit all the speakers in or get 2? 1 for the subs and the other for the smaller speakers. and is a Rockford Fosgate amp good enough for all the speakers i need
