Like the title says...

I am in need of help in wiring up 2 10" Memphis Sclass dual voice coil subs in a SuperCrewSound enclosure. I noticed that there are 2 external terminal jacks. One per speaker. I also noticed that there is a piece of MDF that divides the two sides of the enclosure inside, so running wires from speaker to speaker won't work.

I am looking to do this wiring setup, but am concerned about wiring in the enclosure.

See the following attachment to see how my setup is. Can someone connect the dots for me to see how I should wire it up? Should I drill a hole in the dividing piece of MDF inside the enclosure so I can run wires from one side to the other? Am I going to only use one external terminal jack? Or Both?

Thanks for the help. All of the wiring diagrams I've found don't show how they are setup in enclosures.

I don't have an answer to your question but a question for you. Where did you buy your subs?

Just bridge at the amp:

Well, that's easy enough. The subs are 300W at 4 ohms, and the amp is 600W at 4 ohms, so this setup will give 300W to each sub at 4 ohms, correct?

I assumed the subs are 4 ohm DVC from the pic in your first post.

Each sub has two 4 ohm voice coils, in my drawing those are wired in series, which makes each sub:
4 ohms + 4 ohms = 8 ohms

By connecting both subs to the amp in parallel, you effectively half the impedance:

1/(1/8 ohms + 1/8 ohms) = 4 ohms

As long as both subs present the same impedance, they will get equal power. In this case 300 W RMS each.

Fantastic. Thanks for the clarification. Yes, they are DVC subs.

I used to be big in live sound, but over the years, I've forgotten a lot of the knowledge. This is helping bring that back, a bit.

You could drill a hole and run a wire through the hole to each sub. Then seal up with silicone around the wire or bridge at amp.
