Everybody wants to have a nice, crisp, clear home theater surround system. There are two problems with this: The cheap ones involve a lot of wiring and work and take up a lot of space. The ones that don't take up a lot of space can cost hundreds of dollars.
I have come up with a cheap solution that is compact, almost completely wire free, and makes use of those old 1970s portable Stereo Radio Cassette Recorders gathering dust in the garage.
Step 1: Gathering the Materials
> FM Transmitter (one for wireless headphones might work)
> 2+ Portable Stereos with FM Tuner
> 3.5mm Stereo Auxiliary Cable [or] Red/White Cables (Depending on the Output on the device and the Input on the transmitter)
Step 2: Set It Up
The FM tranmitter I happen to be using has an Aux IN and an Audio OUT, which is essential to this working. To start, you will need to find an empty radio station (no sound or constant static) on your FM tuner. When you have found one, tune your FM Stereos and your transmitter to that station. Most transmitters have a signal radius of acout 15-30 feet.
Step 3: Make the Connections
This step is a little bit self-explanatory. You will need to connect your audio source to the Aux. IN on your transmitter. All of the connections are shown in the schematic below.
