Quick electrical question...and a few more

Easy way to find out the current draw... What's the amp fused for? 5 amp fuse? 10 amp fuse? 30, 60 amp?

It will give you a worst case scenario for draw, but bank on at least 1/2 the fused rate.

My car amp is fused 50 amps, but will consistently draw 35 when driven hard. So they bump it up a bit to be sure. Its gonna blow them if the output gets dead shorted anyways.

Danny_galaga-lol...I know seems overkill but I have very little room and am worried about overheating with all the electronics inside so 2 input fans and 2 output fans-

No digital amp? 420 watt is ridiculous, you can drive a small concert with that. So you either have a small feet-heater in your car, you are deaf, or you use the lowest of the lowest db/watt speakers you could find.
I have a battery-powered T-amp, that does 15 watt max, yet on my 90db/watt 2 tower-speakers they fill up the whole living room with clear 100+ dB.

On Topic:
What system is in the bartop?
A hacked laptop can be vented passively with ease.
And for the bricks: they are on purpose 1-2m from the unit they feed. A built in PSU is shielded, these plastic bricks are often not inside the gadgets because of EM interference. It will probably work, but it might bring troubles.

Cenobyte:

I think 4 fans is overkill too. I recently built a Weecade (with TFT, which gives off less heat than a conventional monitor) and all I have is one fan on the CPU. I had the thing running for a couple of evenings and everything stayed nice & cool.
