Apologies for my tardiness guys, I've been a bit busy doing further research on this.

I need to make some small amendments after reading your posts and doing my further research. It seems I have a wasted band that I chose and that would be the 50Hz band. The speakers response range starts @ 85Hz so anything below that is kind of wasted. Here are the full specs on the speakers (as I know them).



So the new bands are 120Hz, 480Hz, 1kHz, 3kHz, 12kHz (5 band) + 240Hz and 8KHz (7 band). I also realized that an on-off switch is more or less pointless but I will need to keep the volume control.

Radioshack should have a kit for the amp.
As for the equaliser thats a bit more tricky but something like this - http://www.quasarelectronics.com/sma...-equaliser.htm should work ok.

Personally I would take the easier route by finding something that already does what you want (car stereo, or audio seperate) and then remove the parts I want and repackage them.
A look through the RS site didn't reveal any kind of amp kit, only this, which seems a bit under powered and uses 9V.

That link to the Eq is neat, too bad it's mono. It did give me some ideas so I did some further searching to see if I could find something a bit more useful. I did find some links I need to read a bit more completely.

As for repackaging something already available, most everything is either too expensive or has a fair amount of extra crap that I would need to figure out how to get rid of yet keep all the functionality in tact which is kind of beyond my current skillset. I also happen to have beside me a Pyrimid 10 band, 200W Geq (that has now for some inexplicable reason, just crapped out on me[no smoke]) that I could have done this with but when I opened it. . .well. . .lets just say it isn't pretty.

Depth may be an issue for the filtering caps and any reason you want it in your computer?
This is for a portable MP3 server, so the emphasis is on being 100% complete, portable and compact. Normally, I wouldn't bother going this far for something like this because WMP has a pretty decent Eq already and there are a host of third party software Eq's as well but, there is my problem, this isn't going to be a windows system. It's going to be a Ubuntu system and from looking around, there is only 1 half way decent music player that has a Eq built in and it's a bit flaky from the little bit I've been playing with it. During my writing this post, I just discovered another Linux music player (Banshee) that seems a bit better than the one I had found (Audacious) but I still like the idea of doing this via hardware better yet.

In the course of my research, I found this amp that I may have access through a couple local outlets, would this be a better choice? The case I'm using is aluminum so I could substitute that for their heatsink thereby making the unit much smaller for it to be stuck somewhere out of the way.

Anyways; choose an appropriate amp for your speakers. That of course will depend a lot on their nominal load and efficiency. High-efficiency speakers don't necessarily need big amps, but you won't get far with small amps on low-efficiency speakers.
That Scythe is also sitting beside me ATM. With the speakers I'm using, they cut out around 60% knob volume (with WMP and Realtek HD Audio manager cranked up). The unit is also too big (even stripped down) to be of any use.
