Allrihgt, so ive set up our "system" if you wanna call it that in our boat. The only thing is.. I really had no idea what i was doing. It was a ocuple years back and the speakers adn amps seem to work fine. The only thing though is im wanting to upgrade. And in doing so i want to make the best out of the system for the tower speakers, speakers inside the boat and sub. When i get to reading on all of this is seems like jibberish. Im sure im not the only one confused by rms and ohms to certain areas. Stero people can you please straighten out what everything means for me? Thankyou a bunch.
