If your amp is internally bridging the 2 channels then it sounds like you are running them in parallel which results in a ~2.4 ohm load.
BTW to continue beating on a dead horse...try not to mix subs. An angel dies every time someone does it.
Added: Lower impedance means more current which means more heat potentially worsening your problem.... Also I feel the need to state that mixed subs can work....if you put in the time, effort, and have the extraordinary amount of knowledge to pull it off correctly and even then it's more common in Home Theater where environmental variables are easier to anticipate/control, but for 99.9999% of people in car audio it's a bad idea unless you just want to try and get more air moving.
We've been discussing this in my build-planning thread. I have settled on a single good 12" sub (maybe a JL 12W0v3-4) for the good system, in an optimized box I'm building myself. Before learning more, I was thinking of emphasizing different aspects with two different subs, as my build largely focuses on SQ. For now, with this practice system, I'm just playing around and experimenting. I unplugged the 8", just running the 12", and the volume and intensity dropped. When I plugged it back in, it seemed twice as powerful and was more filling (I don't know all the actual terminology yet). If anything, the bass does seem more de-localized with just the 12", but it's still pretty encompassing with both. Even with the more intense combination, the bass is still very smooth and mellow. I'm sure there are aspects I'm overlooking. I've tried several different locations and think I've found the best spots for this temporary combo that will hopefully seem novice by the time I apply the knowledge I'm learning here and elsewhere to better components.
It's funny that you mention 'moving air' because that little 8" actually 'puffs' on my rear view mirror decorations from the back seat, blowing them with each beat.
