Any recommendations for a DIY speaker circuit?

I want to make a DIY speaker circuit WITH MY OWN CHOSEN COMPONENTS NOT A SPEAKER KIT. I would like…
1)the volume to be controlled via a knob
2) to have an on/off switch/button
3) and to be connected to my iPhone via a separate cable.
I would just like some recommendations for a speaker circuit with these things in (preferably from someone with experience) but anyone who thinks they know what they are doing can feel free to answer as well.

Added (1). I want it to be a working iPod dock please

Do you just want to make a circuit, or do you want to make a working iPod dock (speakers, amplifier, crossovers, input board, etc.)?

Your wanting to make a pair of self powered monitors or speakers. Not to discourage anyone from wanting to learn or build and design loudspeakers but honestly its a very complex process and takes a tremendous amount of knowledge and experience to build and design a speak that will sound good. Not to mention typically when designing from scratch there's some trial and error, prototypes and testing to get the final version right. Not to mention your wanting to build self powered speakers on top of that.

How much time and money do you have to learn to build speakers? You might want to read some books like the Speaker Design Cookbook which will give you a idea what is involved.

Honestly it would be cheaper to just buy something made, but if your wanting to learn then kudos to you.

  • Where do I buy cheap IPhone 5 cases for DIY? I want to decorate some Iphone cases, but I don't know where to find cheap, plastic, white or black cases.
  • Where can i find solid iphone cases for DIY cases? I don't want them in bulk because i don't want to spend that much, as i'm just starting. But i can't find simply solid colored cases! I've found clear but no cheap hard plastic snap on cases. White or Black is fine too!
  • Where Can I Buy Clear iPhone 4 Cases For My DIY Cases? I'm kind of scared to order some because of the reviews I see on how the case gets scratched in the mail, or its hard to take off. But I wanted to know if there was a store wear I could go buy the case. Where I stay we don't have a hobby lobby and I know they have some. If you ordered some clear cases from a website and you were happy with it, please give me the link.
