Title: 8 ohm speakers to PC
Post by: urbecrisch on May 17, 2007, 08:27:45 pm

I'm maming a CAB that originally came with 2 8ohm speakers which were connected to the PCB board.  Since I've removed the PCB board and will be using a PC to rum Mame:

Is it possible to connect the 2 8ohm speakers to my PC audio?

If so, how?

Thanks.

If you have an  PC with a sound card with an amp built in you can connect direct but with most on board sound you will require an audio amp.

So if my audio inputs are on board to the MB I don't have a built in amp.  Are there any audio amps that you can suggest (cheap) that I can use for my PC?

Try an old stereo system amplifier.

There are many options available

The prefered method is to make your own from the insides of a 2.0 or 2.1 pc speaker set.
or you can

Use a home stereo amp from thrift shop.

Hit the garage sale scene and find a pair of computer speakers cheap. I have found several pair this year any where from .25 cents to $2.00.

I found this tutorial that looks good. Are there any other good step-by-step websites anyone can refer me to?  Also, is this speaker hack as easy as it looks?  Thanks.

It is as easy as it looks.   There are a few things to consider.

1.  The mod you are looking at uses a set of speakers with a remote volume contol.  If you do not get a remote volume control you will have to hack your amplifier board to remote mount the volume pot or have it accessable in your cabinet.

2.  Oscar contols (mirror) has a mod to add a remote volume control that does not require changes to the amp.
