A few questions i really need help with
1. Would this "diagram" above work?
2. What specifications of speakers would i need (eg how many watts or ohms etc?)
3. Do i need some kind of amplifier? 4. Will it be loud enough or do i need to install a battery pack for power or something?
I would really appreciate any help from anyone.. thanks!
Ipods and MP3 players are designed to drive earbuds that have an impedance of about 35Ω; they wont drive 4Ω or 8Ω speakers; they might drive small 16Ω or higher impedance speakers if you can find some at low volume.
Cheapest way: go to a garage sale where someone is selling "powered" computer speakers. That would have everything you need, including a small stereo amplifier which usually operates from a 9-12V plug-in wall wart. It even has the 1/8" stereo jack to plug directly into Ipod. I have bought a set of small computer speakers for $1.
I remember years back, there were these FLAT speakers that you attached to the wall, and it made the WALL the "speaker"
If you are trying to "Feel the bass" you are out of luck...Unless you use an air pillow. In that case, I would open up a $1 set of ear buds and connect the drivers to the pillow.
I would use a, say, 12 volt battery pack (8 AAs) and a simple amplifier circuit (you may be able to modify the powered computer speakers to run on batteries--it depends on their voltage, current draw, and whether it requires AC or DC).

The powered computer speakers that I have used internally run on about 9V to 12V so you could connect a battery pack in place of the wall-wart. Observe polarity...
