I have 2 mono amplifiers of the same kind and I have a dual 2 ohm sub. Is it possible to put each voice coil to each amp without hurting sub?

Gainmatching hurting the subs is an absolute myth.. I still don't know who made that one up....

You can drive one coil with 100 watts and one coil with 200 watts... It doesn't matter, all power is additive if in phase....

If it isn't in phase you have combining loss, and this also doesn't hurt anything. Period.

You don't need anything fancy to do this, if you want, play a test tone and just make sure the voltage from each amplifier's output is the same. It could be any tone, at any frequency at any level, that part is arbitrary....

And the only reason you would match the amplifier's output is to be sure one doesn't run out of steam before the other....

If it isn't an impedance matching issue, strapping two amplifiers together will never give you the same performance as running them unstrapped. Any time you bridge (strap) two channels (amplifiers) together you cut the amplifier's dampening ability in half.... Other small, but noticable performance reductions may happen.

The ONLY time you should ever strap amplifiers is if your loudspeaker impedance is too high to get the power you want from the amplifiers when operated independantly... I think alot of people missunderstand this....
