I wan't to see what happens if I plug my computer into my speaker cab, but it doesn't sound like a very good idea. My cab is a 1x12, 120 watts, 16 ohms. I have no idea what the ohms output on my computer is and I have to plug a dummy jack into my cab for this to work. Is this a bad idea?

I don't think you'll damage anything, but I'm pretty sure it will 1. Sound like crap 2. Be really quiet. 3. Both.

Well thats a stupid idea as it wont make any sound worth hearing and its probably going to break something.

I know it wont sound good, I just really want to try it.

Your computer's speaker out is designed for active speakers. It's impedance is in the thousands of ohms. It is probably protected, so you won't have to worry about frying it like you would with a mismatched guitar amp, but you just won't get any volume at all. You need some kind of amplifier between the computer's output and the speaker.

The ouput from your PC will not be enough to drive the cab. Worst case you might overload your soundcard getting anything out of the speaker.

I'm not going to do it. I was just curious if it would even work. Stupid idea is stupid.

Depending on the inputs to the amp, it might work. I do it all the time on a baby amp, but it has a "CD" input made just for that. If it doesn't have that, then you will most likely not have the power to drive the amp at all. You could run it through a pedal first for a little boost. But for the cost of a computer sound card and an amp.... maybe not a good idea.

what cab do you have?

But, yeah... Your computer speakers have a built-in amplifier. That's standard fare. Which would, of course, be why it does work with a combo that has auxiliary inputs.

We all know you could blow a speaker by overpowering it. But what a lot of people don't realize is you can destroy a speaker by underpowering it as well...

Grrrrrrr I THOUGHT I read on the Eminence website that underpowering a speaker could cause damage, but I can't find that article now...

I know it's not the same, but I've hooked up my laptop to a combo amp and it works just fine... sounds better than most conventional PC speakers too.

I could see how using an underpowered amp could cause damage. This would be because an underpowered amp driven into clipping would increase the actual power above it's rated power and possibly damage the speaker.
