quick easy mono sub amp question

[2000Sportdriver]

Yes I searched, got a little bit of direction.
Just posting this question for clarity.

I want a mono ( or bridged stereo ) amp to run a single 10' sub.

I DO NOT want to rock the world with this. Just enough to fill the cabin is fine with me. The crutial point is this, I am going to be mounting it in the quarter panel since I have no other locations avalible.
I will be instaling a 12v computer fan and some vents, either way I want a amp that is very cool running.

$200.00 or less. What is a good quality amp that meets this criteria ?

Thanks for all your kind and helpful responces.

I think Alpine has a mono for about $100.00.

I dont know about how cool it runs though

i had a crossfire that performed well for the money... BMF600D: 150 watts x 1 at 4 ohms, 300 at 2 ohms, and 600 at one.
