I just installed this unit in my van. I choose 2 way, since I only have 6 speakers and no sub. What's weird is that this setting seems to cut all the bass out of the rear 6x9 speakers. I was checking the fader and balance to make sure I had the speakers wired correctly, and when I faded to just the back speakers, I realized they were just playing highs. All the lows seem to be from the front door and dash speakers. Is this normal? I was wondering why it seemed like the cymbals were behind me.
