Advice on how to control my sub volume?
I just installed a Pioneer Dmh-a245bt and to my dismay it doesn't seem to have any sub volume controls. It has cutoff for the sub, loudness and bass boost and of course equalizer. I don't use the loudness or bass boost options and it's pretty inconvenient to turn the bass frequencies up and down through the equalizer all the time. It seems like the only way for me to adjust the sub volume is with the level knob on the amp which is both annoying to have to go to my trunk each time and also since it's gain control it's not really supposed to be used as a volume knob.
Am I missing something? Is there a hidden way to enable sub controls? There aren't many options in the menu and I've checked everywhere. Is there anything I can do other than installing a new head unit? Returning my current one is not an option unfortunately.
