amp shuts off

Chances are the amp has one or more shorted output transistors.   Do you have a digital camera and a digital meter?

yes i have a digital camera,and can get a volt meter,do you just need a pic of the board,nothing on it has any sign of burns.but what are the pics needed any close ups of any certain part.and what do i check with meter and what should it read

ok idiot (no pun intended) i went out and hooked it up and the protection light popped on and the wire fell out so i put it back in and it wasnt on,hooked it to the subs and its got sound but i turned the gain,bass boost down,but im not able to turn it up at the moment,i did turn it up half way for a few sec.and sounds fine,so my question besides my others could my fuses be weak so before it pops them it goes in protection mode.or its got a bass boost on with the dbs on it,gain,and crossover,..im not sure what ohms my speakers are or my amp if its putting to much of a load.thanx for any and all information

Is it a 2 channel amplifier?  Is it bridged on the 2 speakers?  If yes to both questions, you really need to find out more about your speakers.  Or if that is not possible, connect one speaker to each channel of the amplifier.   You can not bridge the amp into a load less than 4 ohms.

the MTX subs are discontinued i can find some info about it the 1most helpfull and this is my acual set up box and all.it says its 2ohm,but what im wondering is it says 100-400 rms does that mean it can hold 400 rms or is it a 100.100 watts dont seem like alot of power...the website i found any info is http://www.crutchfield.com/p_236RT12X2D/MTX-Road-Thunder-RT12X2D.html?tp=112&tab=morephotos&pi=1&display=L.my amp is 1 channel and my subs are wired together to one terminal amp seems fine don't know what ohm the amp is ill check.i have hooked amps and radios and subs up before,ive just never knew that the ohms were important to match up.if you could sum it all up with last post i leave you alone,thanx a mill.
