Thank you for all the input but i just want to make sure because I know some amps cant be linked can my Rockford be linked 2 another Rockford 325.1 when I buy it?

Yes it can

Thanks alot guys big help

one more way of doing this would be to pick up a cap, run your main wire in to it then split down to two smaller wires on the other side of the cap, thats how i did mine. Its may not b the most cost efficant way but now i cant keep a watch on the voltage going to my amps
