Hi  I am soo stumped on how to wire this Adire Audio Maelstrom Dual Voice Coil Sub.

I have the 250W parts express plate amp that's four ohm.

I think the Sub is four ohms too.   Can i get a link to a wiring schematic?  Adire Audio isn't around anymore.

Thanks!

According to the driver specs it is a dual 8 ohm voice coil.

If you have two 8 ohm voice coils, how would you get 4 ohms from that?  Look at what happens when you parallel and series connect two 8 ohm resistors and you will find your answer.  Once you have the answer then connect the amp to the result.

My (highly fallible) recollection is that the Maelstrom came with either dual 8-ohm voice coils, or dual 4-ohm voice coils.

If you have dual 8-ohm voice coils, wire them in parallel to get 4 ohms.  The red wire from your plate amp goes to both of the + inputs on the sub, and the black wire from your plate amp goes to both of the - inputs on the sub.

If you have dual 4-ohm voice coils, wire them in series to get 8 ohms (the alternative is in parallel, but that would give you a 2-ohm load and cook your amp).   The red wire goes to a + input.  Then use a jumper wire to connect the - input next to where the red wire is to the other + input.  Then the black wire goes to the other - input.

If you don't know, wire them in series for now. At least that way you won't cook your amp.

Can you get a measurement on that woofer?  Even a DC resistance is better than nothing.  Until you know what you are dealing with, I agree with Duke that you better run the voice coils in series to protect your amp.
