Thanx for the replies. I think I'll try it. I have an XS5100 up front, and 3 Deka 9a31s in the back with an upgraded alternator, so I think it will b okay voltage wise, I just didnt know if it would clip the amps. This is really my only drastic change left 2 do to get that extra 4 db, but hell, who aint needin 4 more db?!
