Can my M50 run this?

I'm wondering what kind of sub I can run with my M50 once she's all new again... Back in the day I ran 2 kicker solo-barics... But I'm sure things have since changed..

If not, is there a recommended sub to work well with the M50?

you could run the m50 @3ohms mono but those kinda subs need loads of power and i think the m50 will struggle a little, m100 yes. i would go for a more efficiant design like idq for example.

Could I dedicate my M44 to the sub and use the M50 to run the components? Not sure how / if the M44 can be setup to run a single sub (dual voice coil)...
What about the infinity kappa perfect 12dvq?
I'd like to use either a JBL or Infinity sub (discounted prices)..

I ran my M50 for years on a Xmax 10" - works like a charm

The M50 will put out ~245 watts RMS at 4 ohms mono. That particular sub is designed for 700+ watts RMS. You may not get full potential out of the sub do to under powering it.

Best using the M44 for your sub front and rear speakers each bridged on a voicecoil and us the M50 on your components.
You will have 100 watt per voicecoil at 2 Ohm.
Iff you do so, use a mono signal to the amp and before hooking up the sub level the gains off each channel with a multimeter to be sure they are exactly the same.
Off course you have to filter the sub before the M44 and you cannot use the sub out then.

Agreed. I had been using small 8" sub the last 8 years or so. In the last year, in playing with current normal sized subs, I have quickly found out that today subs need a lot more power than the 'back in the day subs'.

what kind of sound are you wanting?
a rsd10 is a good choice for sq...a pair of ryval 12's would get nice and loud...

I'm not looking to rattle the neighbors windows... just some crisp bass with depth. If I can do it with a 10" that's fine too.
And, since I can get a good deal on harman products, I'd prefer a JBL or Infinity sub.
And, I'd like to power my system including 6.5" components, 6.5" coaxles and sub with my M50 and M44 amp. Infinity and JBL both make dual voice coil subs if that helps get some power out of my amps..

i don't think the DVC would benefit you because the m50 should be ran at 4ohms bridged
i don't have any experience with either JBL or Infinity subs...

At 4 ohms bridged it's rated at 200 WRMS.
So I shoud look for a sub rated at 200WRMS (not peak)?

just to chime in also....that sub would be a huge waste of money if all you have is an m50 to throw on it.

yessir.
it doesn't have to be exact. you could go as far as to run a Kappa series
of the manufacturer's you chose you should be fine running the infinity reference and kappa, or the GTO series for JBL.
i haven't ran any of those subs before so i dint really have much more input then that
