Mach 500 second sub

Is there a way to add a second sub to the Mach 500 without splicing wires? in the included picture, there seems to be a place on the amps for a secondary input, but if anyone has any information about adding a second sub, especially detailed instructions, that would be very helpful as I'm pretty new to this. the sub I'm putting in is an Alpine SWR-1223D 12" Dual 2 ohm Type-R Subwoofer. Specs:
Peak: 1800 watts
RMS: 300-600 watts
Frequency response: 24-200 Hz
Sensitivity: 83 dB

I currently have all of the the mach 500 stock speakers, and a Kenwood DNX571HD HU. I would prefer to not have to buy a new power amp, but if it is absolutely necessary, please tell me. Even if so, if you could suggest what kind, and give some further instructions for installation, that would be much appreciated. Thank you in advance

Mixing subs is never a good idea unless they have very close T/S Parameters IMO

Unless the Mach sub is gonna be crossed over and used as a midbass driver.

I mean, yeah, as long as both speakers are being utilized. Any advice on how to wire it that way?

I believe the Mach amps are 4 ohm(s) and is probably not 2 ohm stable(I am having a hard time verifying the info on it) so, I do not think what you are attempting to do will be stable for the mach amp. AKA blown fets(inside the amp)are in your future. Much of what I've read is not to attempt to modify the Mach system. If you are not satisfied with it, pull it out and put something else in it's place.

The sub you have noted can be wired at 1 ohm or 4 ohm.

It does not work with the Mach system.
