ok well im going to be ordering a couple stinger fans for my false floor. I dont really know anything about these, i just understand the concept that one pushes air under and one pulls it out. So obviously I need two, do you think I will need any more? It will be a JL 300/4 and a Kicker kx 1200.1.
Do you guys know how to wire them? They say they are 12volt fans so I assume I can just hook them up to my dist. block or something, but it looks like they have two wires coming from them, do they need to be grounded or something?
anyways heres the link to the ones ill be buying

Pretty much anything that is electically powered needs to be grounded. You might wanna tap into the remote turn on lead for the power wire so that they turn on when your amp does. Or you could wire a switch to them.
Its up to you.

alrighty so the other wire is for grounding

If you wanted to, you could put both fans on one side. It may be easier to hook up that way.

I would do the push pull concept. If you can put one fan on one side of the enclosure and the other fan on the other side would be best. That way you know the air will flow all the way across the amps. As for the turn on, check your local electronic store and they should have and adjustable thermostat. I had one conected in my last stereo mounted to the bottom of my sub amp. All I had to do was dril a hole in the botton of my amp rack and use 2 rubber groments to adjust the height so the sencor touched the amp. Worked really well, and only ran when the amps had been on for a few min and started to get warm.

A couple of things. first not sure which ones you are looking at, but you should get the crossflow fans, they flow much more air and are very efficient. As far as wiring, if you are running any more than 2 amplifiers, you need to wire a relay into your turn-on lead so that you don't run the risk of burning up your decks turn-on circuit. Especially if you are going to run a set of fans, the added amperage could burn it up. It's worth the extra protection.

these are normal 80mm PC case fans.
they have an arrow stamped onto the fan casing to show blade direction and air flow direction.
wire to ground and 12VDC.
install fans with one sucking air in, one blowing it out.
all done.

The cross flow fans would be so much better, but are way more expensive.
You can just get PC case fans as Kiki said. Or better yet pick up 4-6 7K RPM PC chip fans....hehe

if you go that route, I'd suggest you use 120mm fans, and add a resistor to drop voltage for the fans to 7VDC.
they'll be MUCH quieter while still moving a lot of air, when compared with those high-RPM black-label fans. Those things howl like banshees.

Oooohhhh soooo true. I like to go by the CFM # and the noise output.
