  1. I was once considering doing something like this, and here's what I'd do:

    - Two separate amps, or a two/4channel.

    - Build two separate enclosures, or 1 enclosure with two totally separate (sealed from each other) chambers

    - One for the SA 12(s), with the recommended airspace, tuned to ~20 Hz

    - One for the SA 8(s), with the recommended airspace, tuned to ~40-50Hz

    - Make sure that the low pass on the Amp for the SA 12(s) are at or slightly below the tuning frequency for the SA 8 enclosure

    - Make sure the High pass (Or subsonic) on the amp for the SA 8(s) are at the same frequency it's at for the SA 12(s) low pass

    - Adjust the Low pass for the SA 8(s) to meet the High pass (or subsonic) for your Mids amp, and adjust them both higher/lower (but still matching) until you feel that it sound right with your components.

    You might have to make some adjustments to your gain to get the SA 8(s) and SA 12(s) to sound even, but you should have a relatively flat response from <20Hz to whatever you set the SA 8(s) low pass to.

  2. Yeah, for daily. Tlines essentially free air the sub so you want to stick below or at the highest the rms of the sub so you don't bottom it out.

    I would stick with a good amp with an rms of half the subs rms to be safe, but if you want to go higher take note of what volume it seems the sub is starting to stress and don't go above that volume or turn the gain down.
