OK, I have the box with the woofers from a Klipsch ProMedia Ultra 5.1 system, no amplifier. I'm thinking I'll fill the hole in the back with a nice piece of stainless steel. Then use a Pyle PT-2400 amp (mono mode) to drive it. (The amp's B outputs will be used to drive some DIY shakers when I get to that point.)

So, the whole thing will be: A/V Rec sub out > Pyle amp > Sub (and shakers).

Does anyone see anything wrong with the basic concept?

Do you think I'd be better off driving the subs in series, with the amp bridged, or individually, unbridged? The voice coils are 6 ohm impedance, and Pyle said the amp wouldn't be happy driving a 3 ohm load. So it's series, or individual.

Thoughts?

Generally, I don't like bridging down an amplifier more than I have to. A bridged amplifier runs a lot higher distortion, always. It has less headroom, more risk of clipping... In short, it's a sub-optimal solution.

Running it in 2 channels into 2 voice coils will have the same overall power as bridged into the voice coils in series, and will allow the amp to remain more stable. Win-win, in my books.

For Home Theater (not continuous use, like for music) use, the amp should be stable enough to run the voice coils in parallel, it'll put out a lot more power that way, but as a cost in clarity. Not worth it, IMO.

OK, thank you for your reply Supra, that was approximately my thinking too, but I thought I'd ask anyway. I'm not afraid or unable to learn, but it generally takes a big stick to pound it in far enough to make it stick. (It helps if you tie me down with some speaker cable first. )
