use two 4 ohm single coils subs, or two 2+2 ohm DVC subs
that will present a 2 ohm load to the amp.

if the amp is rated for, say, 500 watts RMS @ 2 ohms x 1 channel, that'll mean each sub will get 250 watts.

are 2+2 ohm DVC subs the same as 4 ohm? how would those be wired up to a mono?

yes, 2+2 ohm DVC (dual voice coil) which gives a total resistance of 4ohms, is basically the same thing as 4 ohm SVC (single voice coil) (someone correct me if I am wrong bc I am also fairly new to audio)

Dual Voice Coil (DVC) subs give different wiring options. For example, a 2+2ohm Dual Voice Coil sub can be wired in parallel (positive from amp goes to the positives of each voice coil, negative does the same.) This creates a 1 ohm load from EACH sub. Or, you can wire the voice coils in a series configuration (amp's positive goes to positive of voice coil #1, amp's negative to the negative of voice coil#2, then, negative of voice coil#1 goes to positive of voice coil #2.) If you're confused, here's a site with visual diagrams. ring.html

What subs would people suggest for the MTX 421D mono amp? I would prefer using two 10" subs.

I have 2 10" rockford fosgate hx2's in the back of my single cab f-150. Since they are a dvc subwoofer at at 4 ohms each, what would be the best amp to use?? and how should i wire them??

comp vr and kx400.1 is a nice lil combo. you need to have a 4 ohm DVC or a 2 ohm SVC sub to get the 400 watts rms from the amp, in order to get a 2 ohm load to the amp.
