I currently have a DIY box i made 1 year ago using a Stryke audio AV15 ported ina 3 cubic foot box. I am using the rhythmik amp with it. My q is i want something more powerful than this setup. I almost jumped on the bandwagon of the JL Fathom F113, but man 3300.00 is allot of money for Bass... What is a better sub than what i have? I was thinking a tumult and the 1200w plate amp. What do you guys think?
