I have a 4 channel amp powering a dual voice coil sub. It works.

I used to run a dual 4 ohm voice coil sub with a 4 channel amp, it was a 12" Bazooka P. Miller series and an old school MTX Pro504, actually worked pretty **** good.

One thing though, that 4 channel amp is gonna work pretty hard since it's running a sub and the lowest impedance it can handle so it'll get hot. My MTX overheated a few times while bumping Ghetto D.

A class D mono subwoofer amp is a better choice but hey if you already have the 4 channel laying around then I don't see why not.

Not only will it get hot its ***** alot more juice then a class d.

I've ran a pair of IXL10's off of a Cadence 4 channel when I didn't have a true sub amp to use...worked just fine.

So much fail in here. What the OP is doing is perfectly fine. You could run only one coil, and leave the other coil unpowered and the sub would be fine. Exact gain matching doesn't matter. The voice coils are pushing in the same direction not apart from one another.
