hey hey big pimpin,word nucka word, foe shezzy. " edit " IMO just stick with the 2400bd if you do not want to upgrade your electrical system right away,,, it would be benificial to atleast to the big 3. I think the 2400 would be plenty for 2 12" l7's it will most likely put out around 1800-2000 watts wired / tuned correctly....
