Rockford Fosgate Punch P1572 5 x 7-Inches Coaxial Speakers $53 Amazon. This had been on the "to-do" list for a while and wanted to get it done before our trip to Hershey in a few weeks. Sounds better now. Oh, by the way, the AC will surprise you and drench the open driver door just as you start soldering, heh heh. Other than having to hit Bigfoot real quick to divert the water, this is about a 30 min job.
