I have an MA15D4 sub woofer. I got it from a co worker that no longer works with me and said to keep it. I was wondering what kind of amp i can run on it. its a dual 4ohm at 400 watt. how far would you guys think i could push it?

All I can tell you is, If you push it too hard only once, you can not take it back.

Depends on how heavy it is, if you are going up hill or not, whether or not it is in a shopping cart, what kind of physical shape you are in....

You can push it 'till it don't go no mo'. 
You can push it all the way to 400 watts. What kind of question is this?  It's a 400 watt woofer, what kind of answer were you expecting? ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

i know he bought it, i was there. It was when circuit city was falling, he went in and got it for real cheap like 80 dollars.
ive tried to look for an amp for it. i can find ones that are like 350 watt at 2 ohm but nothing 400 i can find 450 watt but not 400 watt. do you think it can got to 450 or 500?

No, you are not in the wrong section, but the ratings on a woofer are there to tell you how far you can "push it". They aren't just arbitrary numbers, they mean "this is how much power you can apply to the voice coil(s) of this woofer".
I would suggest a mono amplifier rated at 400 watts into either 2 ohms if you wire the voice coils in parallel or (conveniently) 400 watts into 8 ohms, if you wire the voice coils in series. A stereo amplifier rated somewhere around 150 to 200 watts per channel into 4 ohms would also work. Bridged into the 8 ohm load of the two voice coils wired in series, this would give you between 300 and 400 watts.
You could also use an amplifier rated around 300 watts into 4 ohms, and only run one voice coil, leaving two of the terminals disconnected.

You most certainly can ask anything you need to, just expect some rather odd answers at the same time. Hang around the site, there is lots to learn even from some of us with a rather odd sense of humour.

why push it to the limit. why not just enjoy it.. it is so much better to have sound quality then ghetto base that shakes the car next door.. my 2 cents
