I dont think he is going to gain much if anything just doing a sub swap. Give us the box specs, or its net volume and tuned at what? To keep the same box you need to find a sub that best fits that box size (sub that plays best in the volume you have) or its time to upgrade to a different box (which you dont want to do) I know first hand the 95 subs are SICK! So is the jugg didnt HEAR to the ear much difference, but you swap to a pair and its like light and day, either way you look at it you will probably need more power to get where you want to be, and thats not much battery power for a system of that caliber you need battery power to keep your voltage up so your amp performs as you want it to...
