How should I run my subs?

[brewski 10+ year member]

I have a Rockford 200 watt 4 channel amp and 2 MTX 200watt RMS,4ohm dual voice coil 10 inch subs. I am going to run the amp 3 channels, 2 channels to my door speakers and 1 bridged channel to my subs. My question is, should I run just one of the subs or both subs in series?

Sadly, the amp only has enough power for one sub at a 4ohm mono load, if you series the 2 subs you will have an 8ohm mono load and your power output will be very low.

Hmmm... I was told that if I ran the subs in series off the one channel it would be a 2 ohm load and my amp manual says I shouldn't go below 4 ohm load with the mono channel.

"I was told that if I ran the subs in series off the one channel it would be a 2 ohm load"

No your getting it mixed up, parrallel will give you the 2ohms, series will give you the 8ohms.

Ok, so either way if my amp manual says it shouldn't go below a 4 ohm load on the bridged channel I'm better off running the one 10?

Yep.

Uhhhh, yall are forgetting about series/parallel wiring.

Dual 4ohm subs can be wired for a final impeadance of 4ohms

This way you would have a 4ohm final load for that one channel.
