the fifth channel on my amp is rated at 350rms at 4ohms, so im looking for a good 10" sq sub around that power. its going into a 2012 jeep wrangler. space is not a major issue as i intend to put the box in the back and just strap it down so i can take it out anytime i need to. price range is around 150 but flexable. also im not sure if i want to go ported or sealed, i listen to a wide variety of music so im assuming sealed would be better?
