The simplest way to put this, is; you know how some subs have the high pass & in/outs to send signal passively to active sub, and then continue on to speakers?
Ok, now, is there any way to do that with a Dayton SPA500? It does not have outs or a high pass - so I know I cannot do it directly from the sub... but, is there something I could build or buy that would allow for the same type of function as described above?

I have a couple SPA500's laying around and would like to utilize one for "Zone 3" ... where I run speaker wire to my zone 3 speakers from the receiver. There is no way to preamp out to Zone 3, so I need to do it at the Speaker Wire level. Can I put RCA's on the Speaker wires, and splice off of them with a Harrison Labs FMOD in-line Crossover? :scratch:

Thanks for any and all assistance and guidance!

What you need is a "high level" (speaker) input to "low level" (line/RCA) converter. Yes, some plate sub amps have them built in, but not the SPA500. Something like this

This looks right, except of the wattage limitations... What about a Speaker Switcher... Would it work to send the full signal to the Subwoofers rca inputs and just use the subwoofer crossover?

80w rms (more peak) is plenty unless you're running a night club in Zone 3.

For?

Yes. However keep in mind that you main speakers in the zone would also be fed a full range signal from the receiver.
