Hi. Signed up because I'm going crazy. I've done single, dual, and 4 subs before. Never 3 subs and it's been awhile for me too.

I have 3 4ohm subs that I'm trying to wire together and bridge on an amplifier that's 2ohm stable. Guessing it would be a 3ohm or 2.6/2.7ohm from what I've seen... Confused.

Right now I have each dvc subwoofer in series. Would make it 3/8s right? And paralleled all together that would make 8 and 8 is 4ohm on 2 subs... then that 4ohm combo to the last sub series in 8ohm to 6ohm right?? Then bridged would be around 3ohm?

Or am I paralleling them each... 4ohm to 4ohm is 2ohm each speakers then series... (math) first two subs 2ohm to 2ohm series is 4ohm... Series to the last 2ohm is 6ohm?? Then bridged would be 3ohm?

Please help or direct me 🙏

I'm assuming these are right but just making sure these diagrams aren't considering half the ohm load due to bridged or mono amp. I don't want to go below 2ohm.

3x DVC 4 ohm subs

Each individual sub in series would be 8 ohms

Then 3x 8 ohms in parallel would be 2.67 ohms.
Okay... Thank you! But if I'm trying to bridge a 2 channel 2ohm stable amplifier?

Then you'd want to run the 6 ohm setup--> series/series @ 6 ohms. 2 channels that will run at 2 ohms by themselves usually only run 4 ohms bridged (as 1 channel). I would really recommend getting a mono block or just rethinking your system entirely.
