rCadeGaming:
Is this a driving cab?  If so, just leaving the seat on casters is not a good idea.  When you go to stomp on the brakes you'll kick yourself away from the screen.  If you're using the casters to allow yourself to roll into the machine after sitting down, why not use the car seat's adjusting function, which locks in place?

DrakeTungsten:

Yes, it's a driving cab. The pedals are on the same MDF sheet that the seat is on, so there is no possibility of pushing myself away from anything. The seat/pedals platform is on casters only so it would be easier to make any gross adjustments to the distance between the monitor/steering wheel and the driver, and for initial installation. I do indeed make smaller adjustments with the car seat's mechanism.

don't feed them frequencies they aren't designed to reproduce. make sure you enable an LPF and/or adjust the cutoff down to around (or even under) 80hz. no sense pushing frequencies above that to them since they won't be reproducing them. all you'll be doing is heating up your voicecoil.

I do this with the crossover, right? I wasn't sure if the crossover works with the speaker-level input/output. It describes the speaker level input/output as a pass-through, which "sums" both channels to grab the necessary lower frequencies for the woofer.

Aaaaah.  From your previous post, it sounded like it was just the seat by itself.  Makes sense now.

Fursphere:
I have one of those shakers in my driving cab.  Works pretty good.  I used a different amp though.

I have been considering adding a second shaker, just to REALLY make it shake.  :)   

My computer is on the ground new to my cabinet, isolated from the vibrations - because I too was worried about killing my HDD.

yes, it should pull out unneeded frequencies out regardless of which input is used. all the speaker level input is, is a couple of resistors in line to bring the input voltage from speaker level (basically a 26db attenuator) to line level that inputs it to the amplifier.

if you are going to use a computer, you may as well grab yourself a soundblaster audigy or the likes for $20, it'll have filtered sub output you can control with the computer.

the dial on the left is your crossover frequency and the right is the gain control.
