Okay, I'm looking for one of these or something like it to control my Sub. Anyone care to give me the proper name and where I might find one that plugs into the RCA output? Yes...a NOOB Question!...Sorry.....
maybe something like this: http://www.sounddomain.com/sku/COUXM2 it's got a sub level control on itare you thinking of maybe an external crossover that has a subwoofer level control on it or an equalizer? there are also head units with sub level control.
