Connecting the speakers in series wouldn't stress your amp because it would halve the load anyway. By using resistors you are wasting power unnecessarily. Does your amplifier have a 'mono' switch?
There's no mono switch. I've looked for diagrams showing how to wire in series, but I don't comprehend the diagrams... cuz the diagrams just show a single speaker connection on the back of the amp/receiver... + & -. The diagram then shows two speakers being connected in some way to that + & -.
How do I connect these two full rangers in series to the L & R speaker terminals on the receiver? And then once that's done, how/where do I connect big woofer?

Ok. First off, don't connect the L & R together at any point. What you are wanting to do connecting all three speakers together and to the two channels is not possible, you will damage your amp. Is it really not possible for you to remove the polks speaker?
I see L & R connected together in series... like in the attachment.But as I look at this, I really don't get it. Two speakers attached to just one pair of + & -. WTF?

Seems a shame to give up now. How about you just connect the 15in and one of the 8in in series to one of the outputs of your amp as shown in your diagram and try it through one channel?
So it seems that series and parallel wiring are just for when you are connecting more than one speaker to a pair of + & -, right?
That isn't what I ment but actually it would give you a similar idea to how the H frame would sound and you wouldn't be loosing any power. Go for it!
Ok, what I ment was connecting them in series to just the + and -. But what you suggested is fine to, actually better because you will be using R and L
Or I just figured out that I could connect up the 15" sub and 8" full ranger as a serial connection (but won't it be 16 ohms?), and then connect the other 8" to the other front output as usual. That shouldn't stress the amp out.
Yes you can do that, it will be 16 ohms but that is not a problem for the amplifier it will just be quieter
Thank you for trying to help me out. Is there a way to do this right? I really did not want to have to build much of a crossover. And if 16 ohms is going to quiet things down... well, I don't know if I am OK with that.
How can I keep all this at 6-8 ohms?... which is what my receiver can handle. If I built a second big woofer H-frame, how do I wire it so that both L & R speaker outputs are 8 ohm?

scottjoplin... thanks again.
If I got a receiver that was 4 ohm stable, and had two sets of speaker outs... A & B, and it had an "A+B" switch, couldn't I connect the 8" full rangers to speaker set "A", and then connect the 15"s up to speaker set "B", and then play them together by selecting "A+B"?
Wouldn't that work?

Yep that would be perfect because you can connect all the speakers directly to the amp, wiring in series can sometimes turn out to be a bit of a mess. Also you would be able to switch the subs in and out to compare the difference
This is why crossovers exist. Summing two channels into one driver is done with dual voice coil drivers or with (at least) resistance in series with the single driver type that you want to use. What if you just tried using what you already own, namely a plate amp in your Polk sub which handles this problem and which also has a low frequency reducing capacitor in its satellite speaker outputs? In addition the sub amp has a level control. Why not use it???
