I was in electronic express yesterday looking for a fuse holder, ad I saw that they had L7s. So you could drop by there and have a listen.well all things being equal this sub will most likely have the most output compared to other subs of the same price range/class ... you can always goto circuit city and listen to the L5's, but remember that you sub is the next step up so imagine it just a lil bit louder or see if the employee's will let you clip the hell out of (the ones where i live dotn give a shit whta we do LOL)
