I am not getting good sub response at all from the factory sub/amp combo. I have a 2011 22ssv and I believe it a 10" woofer sealed box under the drivers helm and is a on a 700.5 kicker amp. Was hoping to swap the sub with a JL W3 an see how it sounds. I am not looking for crazy bass but the setup from the factory provides almost no bass at all. Any suggestions?
