9500 subs come in either single 4 ohm or dual 4 ohm (see https://www.mtxaudio.com/caraudio/products/subwoofers/thunder9500.cfm). So..the best you can do is use the DVC 4 ohm and wire parallel to 2 ohms. The Memphis amp will output into a 2 ohm load, which will be about 600 watts to each sub (see https://www.memphiscaraudio.com/products/details.asp?cat=&id=66&p=2).

If you want to get 1000 watts to each sub with the two amps, you will have to choose a sub that is available with a DVC 2 ohm voice coil configuration.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Since the day when someone decided he wanted to run two thousand watts for subwoofers. posted_image

Any time you make a change in your system you are opening a whole new can of worms. The can you open with a doubling of power will be one that will take some time and effort (and $$$$) to get through.

...and your Memphis amps will have hookup instructions.
