I have absolutely no clue how to pick an amp that will match with my subs i have 2 Pioneer TS-SW301 12-Inch 1000W Maximum 250W Nominal Shallow-Mount Subwoofer. So can someone please help me on how to choose a good amp to power the 2 subs. I also need help choosing a head unit. Any help is appreciated. By the way this is my first time with a system so thanks again with all your help.
