I have a Sony Xplod (yeah I know, I got it off of a friend for cheap) deck and new Pioneer speakers and a new JL sub. I don't have subwoofer controls or anything of the sort... just bass controls. Right now I am having issues with the bass. To get bass out of my sub that I like, I have to turn off the bass out of my speakers so I don't blow them, but then it sounds as if the sound is coming out of the rear speakers even though it is coming out of the front also. I guess what I am saying is it is not loud enough (inside speakers). Should I turn the gain down on my sub? Would getting an external equalizer be okay, or should I just buy a new deck with subwoofer controls?
