Stupid Question-Mono Amp, More Terminals Than I Expected?

[johnnyyukon]

So my amp arrived  for my single dual coil 12 inch sub and I was expecting 1 negative output and 1 positive.  But there's 2 neg, 2 pos.

I'm guessing that's for the option of powering 2 speakers?  What do I do/use for just the one Subwoofer?  

Thanks, sorry, amatuer.

It's just one channel.  Just two places to connect wires.  Use one, use both, doesn't matter.

If you connect to both pairs of terminals you're wiring parallel.  A 4 ohm sub on each output -- amp sees 2 ohms.

About every mono >500w has two outputs.

Pretty much what he said. The amp is split into a "2 ch amp" internally to offer the buyer/consumer more flexability with multiple subs.
