Planning on putting a pair into 2 custom enclosures in the rear of a club cab dakota and giving each 175watts RMS. Not looking to blow anybody away as this is a daily driver, but I am looking for a nice clean sound. The subs are a definite, the rest I can change around if required.

Any suggestions appreciated.
