Well my other option was to go with a 15 Mojo running off of a Soundstream 4k, but that would take up a tremendous amount of space and I really DON'T want to have to get another battery put in. I'm not too knowledgeable for the higher end setups (I currently have two 8's running off of an 1800 watt amp), but I want to make the space that I do use make the most noise for me, lol.
