Wire in Series or Parallel?

Differences in the two? Is it just the ohmage?

depends on what your amp is stable at

You mean AG 750. It is stable to 2 ohm stereo 4 ohm mono.

Go here for your manual:

Click on products, scroll down to heritage and click on your amp.

Yes, that one. I make that mistake all the time.

According to JL, series is 4ohm... so I need to wire in series (2 subs) into the mono (bridged) output, correct?

What subs do you have?

Parallel is both + together and both - together. The math is
(R1 X R2) divided by (R1 + R2)
so if you had 4 ohm subs it would be:
(4x4) divided by (4+4) = 2

Series is the + from the amp going to the + of sub 1 then the - of sub 1 feeding the + of sub 2 then the - of sub 2 going to the - of the amp. The math is just to add the ohms up (R1 + R2) so two 4 ohm subs in series would be a single 8 ohm load.

Since your amp is good for 2 ohms stereo or 4 ohm mono you cant go with any ohm LOWER than those.

If you have two 8ohm subs then wire them in parallel for a 4 ohm total load (R1 x R2 / R1 + R2)

If you have two 4 ohm subs then run the amp in stereo for two 4 ohm loads or wire them in series for a single 8 ohm load (R1 + R2).

If you have two 2 ohm subs then run the amp in stereo for two 2 ohm loads or wire them in series for a single 4 ohm load (R1 + R2).

If you have two dual 4 ohm voice coil subs then wire each sub in series (for two 8 ohm subs) then wire the two subs together in parallel for a single 4 ohm load (R1 x R2 / R1 + R2 = P1 and R3 x R4 / R3 + R4 = P2. P1 X P2 / P1 + P2)

If you have two dual 2 ohm voice coil subs then wire each sub in series (for two 4 ohm subs) then run the amp in stereo for two 4 ohm total loads (R1 x R2 / R1 + R2).

If you have two dual 8 ohm voice coil subs then wire each sub in paralell for (for two 4 ohm subs) then run the amp in stereo for two 4 ohm total loads (R1 x R2 / R1 + R2).

series parallel

wire the voice coils on each sub in series then wire the subs in parallel for 6 ohms.... or you can wire each sub parallel then run it in stereo with each sub @ 3ohms since your amp is stable in stereo @ 2

Those are dual 6 ohm subs. Wire them in series and you will get a 6 ohm final impedance. Or you can wire each sub parallel (individual), then run each sub to a channel (stereo).

Do you have an amp for your speakers? If so, what is it?

EDIT: Well, styx beat me to it.
