Im not quite sure what model I have but its a kicker L5 in a bassworx ported box. Its in a vert so I may need a sealed box aswell for the 12" L5. Anyway I need an amp that matches this subwoofer......Im not sure if its 1,2,4,8 ohms though, is their a way to find this out? Anyway Im looking for 650+ RMS as that is what Ive been told the power rating is for the L5.....Looking for used amp if possible, please state make and model along with specs and price. Thanks in advance.
