Even then its still not a good idea, due to the natural variance of the amp outputs conflicting in the sub. Even if they are the identical amps they won't be putting out identical signals. Better off building a box with two subs and running them off seperate amps if you want to use up two amps your have a something, or buying a bigger amp. If you ran two amps into two subs in a bass reflex box it would pretty much sound like one signal.

You would have to bridge the amps together but then the total ohm load will change and if you do not match the resistance right, you may have a very unpleasant outcome.
I know that kicker amps can be bridged together, but other brands might not be able to handle it as well.
It is always better to have a bigger amp that you can wire a few different ways to drop or increase power
and ohm load. I have a MTX 1500D and i have used for a few different setups from one 15" Directed to my
current setup of 2 10" Kicker L7's

this is wat i wanna see how i can hook them up better. i have 2 amps and 2 subs.
right now the wireing is set to one amp briged + DVC sub at 8 ohm. i have no clue how much power subs getting from amp at 8ohm. it dont say anywhere.
SONY 12"
Sony amp
i was think this but the two amps at the end?
or amp at 2 ch. 2ohm 200 rms. one ch. to one coil in one sub other ch. other coil in sub. same with other amp. i thinking both amps at 2 ohm 200+200=400rms for each?
thanks for the help already. i would ask other places but i know there is a bunch of smart ppl here so ill ask here first

If you are using both subs are you going to wire them in a series circuit or a parrallel circuit. This matters alot cause you ohm load can vary a lot with DVC woofers.
If you have 1 DVC woofer with each voice coil being 4 ohms and you run a parrallel circuit then the final ohm load is 2 ohms.
If you have two DVC subs with voice coils being 4 ohms wired parrallel then your final ohm load is 1 ohm. only 10% of Amplifiers out there can handle anything below two ohms, and if you do run high wattage at low ohms i hope that your power wire from your battery is around the size of 1 or 0 guage.
According to the info you gave on your amp, and if your subs are DVC 4 ohm coils then i would wire each subs two coils together in a series circuit then wire the two subs together in a parrellel circuit.
What kind of woofers do you have do you know what ohm the voice coils are that is key piece of information!!!
