Just remember to add another battery or two, nothing worse than jamming all day and then no juice to go home. I put 4 8.8's and two 10" subs. It's loud and thumps. But the Jl sound is crystal clear. I did fry an ecu on my Smartcraft 200's after jamming all day at the sandbar and them trying to crank and go home. Was a long slow single engine idle back.
