I'm installing Polk MM 6510's (front) and 651's (rear) in an 09 Jeep Wrangler and am looking for a 4 channel amp that will provide enough power to the speakers. I'm currently running the stock head unit, but that will be switched out at some point in the future. Also, I plan on adding a sub down the road. Any recommendations are appreciated.
Edit: I'm also looking for something that can withstand getting wet as I've been rained on with my top down on multiple occasions.
