I have my ipod connected to my car stereo but the sound doesn't use my subs. Does that make sense? I have a pioneer deh p9300 connected to an 300W pionner amp that pushes 2 10" RF subs. When I listen to the radio or a cd I can hear the music using the subs but when I use my ipod it doesn't use the subs, just the regular car speakers. I have my ipod hooked up through the aux input using a cd-rb10 adapter cable. I have my ipod set to bass boost but there is no bass coming out of my sub. What can I do to fix this?
