I just bought the infinity kappa 4" series for my dash. The reference ones aren't bad but the kappas are awesome. Had them in my s10 and they were great in there too. My brother has a set of Boston 6x9s in the El Camino and they bump pretty good. Personally I'd go with a sundown audio SA-8 in your situation. They don't need a ton of room, but they hit pretty damn hard for 8s. 0.28 ft^3 sealed.
