IS there anyone that knows how to do this? Im kind of disappointed with the bass in my Goat, (yes, ive turned off all distortion/speed dependent volume) and the only thing I can think of is adding a sub. So I got this Sony XM2002-GTR 2 Channel amp that was in my Ion (up until I crashed it), and I want to hook up a single 12 in the GTO. Any kind of help would kick ass.
