Hi All, First time poster. I am having a hard time finding either a place to have an Amp plate checked out (repair) or finding how to just buy a new plate for my R-112SW. I'm having a slight (annoying) hum in it and its overly loud at times. It still works but not correctly, when I disconnect the hum goes away. I have another Brand new R-112SW connect to the same sub cable and no hum so it has to be this sub Amp. Any help on a good place to contact would be much appreciated. I'm in the Plano, TX area so some place close would be good. Can anyone help me decipher my S/N. Like how old this may be. S/N 106070014520230. Thanks. KN.
