Talking velleman 2x 30W k4003 suitable?

Hi. I am making an ipod dock for my GCSE Design Technology. I will be using four X 3 inch cones and 2 X 1 inch tweeters.I have seen the velleman 2x30w KIT and I am wondering if it is suitable. I am probably completely wrong and I am wondering if you have any comments on the 2X30W or any other suggestions for KIT amps that I could use. It also can't be massive because it is only for an ipod dock.

I planning to spend no more than 40 (about $70 US) but still make any comments. I am possibly also considering tubes (I guess there's nothing wrong with them sticking out of the dock )

Thanks vmuch for any advice.
MATT

the Velleman kits work, They tend to use music power in the names though so the "30watt" is really 10watt / channel into 8 ohms.

You will need a power supply and a case, These can be the pricy bits - a bust amp though can provide a good haul of connectors / switches etc - saves a fortune

Good luck with the project

Matt,
I built and use the Velleman kit. I like it quite a bit. It was an easy build and works well. I used this transformer
http://www.parts-express.com/pe/show...number=120-210
and I bought a Velleman K8084 volume/tone control kit. I picked up a nice wooden cigar box from a local smoke shop for the case.
Lots of fun and sounds decent.
Mike

It's based around Philps' TDA2616 chip, which is 2x12W RMS into 8 ohms - this is probably better than most dock kits on the market!

thanks loads for the advice. I guess I'll stick to the 2 x 30W then, and I'll prob get the transformer mikje suggested as well (cheers). But I'm looking for a bit more control than the velleman vol/tone control. Please can anyone suggest any 5-12 band equalizers? (preferred ready made but kits are fine too).

Also, what do I do about splitting up sounds for different cones? do I buy a frequency splitter or something?

Thanks for any advice.
