Hi everyone,
I need some help with wiring my 6x Rockford Fosgate T1S1-12 custom cabinets. I plan to wire them in series (2 banks of 3), but I'm a bit stuck. Each cabinet has 2 speakon jacks and seems to have a bridge inside, but I bought them used and have no idea how they were set up previously.
Ideally, I want to run a single cable to the first sub and use jumpers to connect the other two. If anyone has any advice or can point me in the right direction, that would be most appreciated!
I’ve attached pictures of the current wiring inside the cabinets.
Thanks
Steve

Thanks @AllenB - Understood.
Reference the image from what I will call Jack A I have a standard -/+ coming from amp, + red goes to driver.
The bridge is the white cable which connects - from Jack A - to + on Jack B, Jack B - goes to driver.
All the subs are wired like this.
My hope is I can wire them with jumpers in 2 banks of 3 for a 3 ohm load.
Amp is a NX3000D.

I'm not seeing the inside shot.. but from your description it seems the "bridge" as described isn't bridged, but needs to be for one sub to work. In other words you could loop others in that way?
Are you asking for a description of how to make cables for it? Consider connecting the bridgeable connector to the next sub and that to the next, using a bridge on the last one. If in doubt, draw it out and post what you have.
Your choices of equally powering the six 1ohm speakers with your amp are three speakers in series (1 ohm + 1 ohm + 1 ohm =3ohms per amp side, or all six in series for a 6 ohm load, using the amp in bridge mono.
The NX3000D is rated for 2 x 1500 Watts @ 2 Ohms, 2 x 900 Watts @ 4 Ohms or 3000 Watts into 4 Ohms bridge, so you the speakers would get about 400 watts peak in either configuration.
Try drawing this out and see if the Google AI awnswer to "wiring three speakers each using using two Speakon chassis connectors in series" looks correct:
Amplifier to Speaker 1: Connect the amplifier's positive (+) and negative (-) outputs to the 1+ and 1- pins of the first Speakon connector on Speaker 1, respectively.
Speaker 1 to Speaker 2: Connect the 2+ pin of the second Speakon connector on Speaker 1 to the 1+ pin of the first Speakon connector on Speaker 2. Connect the 2- pin of the second Speakon connector on Speaker 1 to the 1- pin of the first Speakon connector on Speaker 2.
Speaker 2 to Speaker 3: Connect the 2+ pin of the second Speakon connector on Speaker 2 to the 1+ pin of the first Speakon connector on Speaker 3. Connect the 2- pin of the second Speakon connector on Speaker 2 to the 1- pin of the first Speakon connector on Speaker 3.
Sounds complicated..
Rather than using so many connectors, I'd probably just do the series connections on the three connectors that go to the cabinets with the fourth going to one side of the amplifier.
