can 2 amps power 1 set of subs?

This may be a stupid question but I thought I'd still ask.

Can you wire 2 amps into one set of subs?  I have 2 different amps(one Sony and one Blaupunkt) that together would make 700W RMS and 2 dual 4 ohm voice coil  Calarion subs,  can I wire both amps into these subs?

ive never heard of this but i want to know If i can use both amps before I sell one.

                                                                            Thanks for any help

List the equipment you are asking about.  The forum doesn't know whether these two amps are similar, different types or what. 

• If they are both class D mono amps, go ahead and put a parallel-wired sub onto each one. 
• If they are different types of amps, pick the one that is appropriate for your needs and use it only.  See https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=42
• And, if they are both two-channel amps, series-wire each sub and bridge one sub per amp.

Thanks for the help. sorry I didn't include all the information.

There both 2 channel amps, and both are stable at 4ohm bridged.  So with my dual 4ohm voice coil subs I wouldn't be able to use both amps because of the ohm load.

I think I'll stick with the 400W and call it good.
