Default Newby's question about dual coil driver with plate amp

I am trying to build my first subwoofer. I have got a 300+ watt (rms at 4 ohm) plate amp and a TC sounds 1000 12" driver.

http://www.tcsounds.com/tc1000.htm

But I might have made a mistake when perchasing the driver. It is a dual 4 ohm voice coil. I know I should find another 2-channel power amp to work with this driver to meet the specs. But I wonder if I can still use the plate amp drive the dual coil driver since it is already there. And how to connect them?

Thanks in advance.

You can still do it. If your amp is stable at 2 ohms, wire the coils in parallel. If not wire them in series.

Well, my suggestion is if you're not sure your amp can work stable at 2ohms loaded, just wire your bass driver units in series.

From the looks of it no, it cannot handle 2-ohms. Just wire it in series for a total of 8-ohms, which is within the recommended impedence range.

Question how to wire?

I have an old M&K V2-B 12" sealed sub that blew its circuit board. M&K went under in February while holding my circuit board for repairs. Great timing, eh?

So, I found a vendor (ApexJr.) who picked up some surplus M&K sub amps (with higher wattage than the original), and I bought one.

Once I started to test the amp before installing it, I realized that the woofer is a dual voice coil. Incidentally, I hooked up the leads to one (side?) of the woofer and tested it to be sure I hadn't blown the woofer. It pushed fine, so I'm happy about that.

My question: since my amp only has one set of leads, is it bad/wrong/ill-advised to just hook up the single +/- leads to the woofer? What are the other options? Are there DVC amps, or just two amps for a DVD? Help!

As far as I can tell, my original M&K amp appeared to have two sets of leads rather than two discrete amps.

Sorry I'm so dumb, but I could really use some help so I don't destroy what's left of a great old subwoofer.

Thanks,
Phil
