Great instructable. I took your basic idea but drilled a bunch of holes in a cigar box. I used the same Velleman amp, and put it in the box with a speaker, an ipod and a 9 volt. It came out great. Thanks.

I use two 6v wall warts, You could just use one though, I was kinda geeking out on having two separate amps... but its kind of wasteful two use two inputs.

Very cool. I make a lot of Velleman kits and I have a lot of these boxes lying around. I might make this.

now does this become a stereo by using 2 mono amps? or is it still mono just 6 watt or what , sorries for the noob question im trying to get better at electronics

[joe]

Well you use two separate amps, one for each of the stereo channels. So two mono amps equal one stereo amp. Really really hifi applications use two mono amps for the best sound, this is not hi fi though! Let me know if you have any questions. Thanks, -Joe

ya real high end audiophile equipment and really eccentric equipment like th 200,000 dollar stereo amps and what not for rich people that dont know better. but ya the 2 mono amps does make for great sound. ida prolly went with a rca out insteada speaker out. but to each there own aplication. A+ instructable added to my group and as favorite

Totally, I have two options for you:
The 7w amps from vellemen sound really nice.

Or this stereo kit from velleman that I have and I think it sounds great:

awesome, now that kit does it come with the power supply? and how hard would it be to feed in some extra imputs and put them on a switch?

[joe]

It does not, but your localradioshack has it for $6 radioshack has it for $6! You need a 12v center tap transformer.

It would be easy to add a switch for multiple inputs, you would need a 4 pole switch or for $4 you can this switch from velleman:

This is a great project and instructable. If I ever have some time this is my next project in line!

A boombox in the trash might have a broken antenna or tape deck, missing power cord and leaky batteries... but usually a good loud amp... and speakers too. (Unless roaches are living in it.)
