I just got two speakers and a subwoofer, but no amp/head unit (no sure of the term). I'm looking to build one from scratch. I don't need it to play CDs or even have a volume control, I'll be hooking these up to my computer. It just has to supply enough power so I can use the system.
This is the exact system here - **broken link removed**
That one has the head unit, I just have the two speakers and amp as pictured here http://i14.tinypic.com/66vhdg0.jpg
The speakers are unmarked except for a sticker that claims the speaker system impedance rating is 6 ohms. Luckily, because RadioShack sells the product, the user guide and technical specifications are online **broken link removed**
I know how speakers and headphones work. The wires leading out of them look like this http://i8.tinypic.com/4lqe9vr.jpg
I'm going to convert the bare wires into phono (RCA) plugs. That'll make it easier to disconnect them from the amp. I know what all the bare wires are for, but why does the sub have an additional wire with phono plug running out of it? Is it just to supply more power to the sub? Perhaps the sub has a built in amp? I'll have to take it apart and check.
Anyways, what I need is a a circuit diagram. It needs to have a 1/8 jack so I can run an audio cable from my computer to the amp. Coming out of the amp it needs two phono jacks for the left and right speaker, and two phono jacks for the sub. The diagram can have other connections, it doesn't matter. I can figure how to substitute a phono jack instead.
What I'm having trouble doing is boosting the power. From what I know right now, I can receive the audio from the 1/8 jack, split the two channels, and send each one to their respective phono jack. I guess for amp, rather then sending it to the phono jack, I'd have to send it to a transistor switch and that does something and now I'm lost...
I need to boost the power and I need to figure wtf I'm doing with the sub (convert the stereo to mono and feed the whole thing into the sub?). A complete diagram would be really nice, but just a diagram to boost the power and a little advice on the sub is all I need. I'm not sure what the watt rating is. According the RadioShack, its 400watt total (125watt per channels x2). Maybe someone could look at the specs and tell me whats up.
As far as the circuit, I looked through these two sections

http://www.discovercircuits.com/A/au-audio.htm
But I'm not really sure what to look for
Well, now that I've taken up this much of your time, any help?
