Newb here - Help with a project

Hi all.

So I'm pretty new to speaker building and everything it entails. I've been reading up on it, trying to figure some stuff out, but need some help.

So I basically want to create let's say a box that two 7" woofers, two tweeters and a crossover units that will mainly act as a speaker system with a headphone jack to plug into iPods, etc. Now I've found some projects on instructables for speakers that are built to plug into receivers, but I don't want to do that. So can I convert the speaker wires into the headphone jack?

So I'm wondering what kind of power source I can use so I can have full power of the speakers while plugged into a source through a headphone jack, and how I would go about doing that.

Any help would be awesome. And I haven't decided on the parts I'm gonna get yet, so I might need help on that later too, making sure the woofers, tweeters, and crossover will work together. I want to create a semi-high-quality system with good components.

Thanks!!!

So it sounds like an amp is what I'm looking for. I may actually buy a set of Dayton 6.5" 2-way bookshelf speakers and pull em apart and put t-amp between them. The speakers say they handle 40 watts and 8 ohms. Would a Sonic Impact 5066 15-Watt amp work? It says it's compatible with any standard 8 ohm or 4 ohm shelf speakers up to 20 watts. Thanks for the help

Do you know if that has a 3.5mm mini-jack input?
