the wet sound set up or sound pack three has two rev 410's and 6 wet sounds SW650's in boats it has one syn6 and one syn4 to power all of it.
i believe the syn4 is use just for the tower and the syn6 for the in boats.
So how underpowered is this system. and how would you set it up/change it to make it the best. weather it takes adding an amp or what
