I did the same thing your doing in my old S-10, and didn't feel a need to change out the components for raw drivers. I just took out the passive crossovers on my Alpine's and used a alpine 9887 for active signal to a set of 2 channel amps, and it worked great. It took a lot of listening, and adjusting to get it right, but I was very pleased with the end result. It wasn't the loudest setup I have had but it was one of the best sounding with everything being on axis and properly staged and aligned. I had 2 pre-sets so I could aim it for the driver or the center for when someone was with me. If both passengers leaned to the middle on the arm rest the time alignment was almost right, close enough anyways.
