Will a kicker dx 200.4 amplifier run 2 sub woofers of 1200w - MGX

It will push them for abot two min then get so hot its going to shut of and you should get a amp that can push the RMS of the speakers so you don't damage anything!

Give me the specs of the speakers like 4/8 ohms and max power rating.

Also give me how many channels in AMP at what "ohms" and the smallest load it can drive, like say 2 ohms and the powers at each,

It's a 1200w sub-woofer 4 ohms
The amp is 4 channel
200.. 4
200 on per channel

Yout amp manual is here: http://www.kicker.com/sites/default/files/2008%20DX%20200-4%204in1%20a01.pdf

Says 100 W x 2 at 4 ohms in mono mode, so yes it's OK.

Set crossover to LO.

That means I won't get enough output right?

I tried playing it on mono
Its getting too hot
And den shut of for 15 min and red light appears n again starts with the green light

That's 200 watts divided by 4 you are only putting 100 watts to each sub witch will damage both your amp working it so hard and your subs starving them of power that they need
