a second way to help to add one of these on the end of your sub cable, if your sub sill take a left and right input. it give a little bit better response for a very minor investment (technically you're giving the sub more signal, so for the same level of volume you set on the sub, you get a little more volume). they make a cheaper one, but it wasn't showing in on-line stock, so you might ask your local dealer.
