not sure if this is the right area to post this, but...
i want to make a portable retro style 'boom box' with a single 10" Hawthorne Audio Silver Iris driver, that accepts a 3.5mm input from a portable DAB/ Ipod etc. just needs a volume control and a single output to the speaker.
anyone know of any cheapish Mono Battery amps, preferably in a kit or something 😀
any ideas?

The specs on that speaker show that it can handle 150 watts (http://www.hawthorneaudio.com/drivers.htm). I'm not sure that you'll be able to drive it as a boom box with a battery powered amp. Perhaps I've misunderstood your post.

That has *nothing* to do with it. That is a high efficiency driver, it is actually a great choice for a low powered amp application.
Back to the original question, you can make a decent battery amp out of several of the National amp chips, but of course there are plenty of kits too. Do you prefer kit or scratchbuilt?
Any reason you can't use a T-amp or a tripath based kit and parallel the channels? It would save a lot of battery for you.
My first boombox was a mono one built around this amp:
It's $15 from www.brinck.dk (it's the BR320, and is 17watts mono into 3 Ohm @ 14V) but I'm sure you easily find another kit cheaper, or just bird's nest one.
My boombox since evolved into this:

An externally hosted image should be here but it was not working when we last tested it.

I'm wanting to do something similar. Basically, the idea is to make a luggable boombox-type-thing.
The starting point is going to be a JBL Control 1 (4 ohm, 150w rms). I'd then like to squeeze a class-d (class-t?) amp module and a lithium polymer (so 11.1v or 14.8v) pack inside the speaker case.
As I understand it, tripath amps cant be bridged. Anyone have any recommendations for amp modules?

I should probably stress that I am by no means experienced in working with electronics so a nice ready built module is definitely preferable 🙂
It's not actually a single driver. For full range, it seems that they turn it into a coaxial by mating it to an HF driver with a crossover. Since you can't bridge a Tripath, you could use one channel to drive the LF and the other to drive the HF with an PLLXO at the inputs.
