hey everyone i have a quick question. i have to sub amps. i bought another one cuz i thought the one was dead and i tired it again with a diff fuse and it works again. the old one is a 120watt one and the new one i baught is a 150watt one. i would like to know if i can link them. the one has a input and output and the other one has just an imput. they both have high and low level input and out-puts. thanks for the help, Eric
