Sub Question. One higher quality sub or two lesser quality? (Rythmik vs HSU)

I see two speaker outputs on the Dayton. How does that work to drive 4 subs?

2 on each wired in series?

Hello mapman,

     It's actually 2 pairs of speaker outputs on the Dayton sub amp.  I have a front pair of subs connected to the top pair of outputs and the other pair of subs connected to the bottom pair of outputs.
     The connection method of the AK Swarm and Debra systems' subs are also a bit unique as all 4 subs are connected in series/parallel  configuration.

As I read it the two outputs are already in parallel and connecting two subs to each directly would result in 4 in parallel which would could result in loads 2 ohms or less with nominal 8 ohm subs. Two in series to each would seem like a better idea?

Cornwalls are super efficient, so what Brian said makes sense.  I've never felt like they tried to upsell me when I've talked to them.  Did he make a recommendation for your situation?  I'd reach out to the guys at SVS and see what they suggest also.

Sorry I didn't go into detail.  

With one amp and four 4-ohm subs, the connection configuration is series/parallel, resulting in a 4 ohm load.  

With two amps there are several possibilities, but we never ask the amps to drive a load they're not rated for.
