Connecting Car Speakers To PC 2.1 System?

Most solid state amps are fine with 4z loads. The only exception is anything old with an output transformer (early-mid 60s). Some home audio recievers from the "silver" era don't really care for 4z loads, but they'll still run....just with increased heat dissapation and increased distortion.
For my MAME'r I just used a cheap old car EQ-booster thing rated around 10w/ch. The EQ section was noisy and didn't work well, so I bypassed it and ran signal straight to the output IC in the manner suggested by the chip's datasheet. Works fine and doesn't generate much heat. Before that I had a rack mount broadcast power amp in there and it just ran too hot for my liking. I think it wasn't designed to be operated sideways instead of the normal flat orientation, so heat from the pwr transformer/output section was building up inside the chassis.
All you guys sticking a big subwoofer in yer cabs might wanna take note that HDD's don't like a big magnet too close to them....they are magnetic media and you can erase the contents by having a large magnet in close proximity.

I'd hope yer using a 5w wirewound and not a half watt carbon film for that. They do make a nice fuse tho....

Dude....buddy....holmes....they go down to less than an ohm at half watt. This ain't my first rodeo...
