How can i cheaply make a headunit tester? All i need to be able to do is check RCAs, power up, and speakers. Is there one i can just buy, or a cheap DIY way?

still curious if there is any way to do this?
The thing you need is an AC to DC power supply... radio shack.. to power the head unit, then into conventional little bookshelf speakers for speaker level leads or RCA out to an integrated amp or receiver or plain power amp to check your rca outs... Here's a thread where it's actually done...

That is if you're "testing" by listening I guess... I imagine alternatively you could run a signal from the rca's or speaker level outs to a scope as well if so inclined... Listening would work for me. :)
Looks like this might be the supply he used... http://www.radioshack.com/product/index.jsp?productId=2103961&cp=&sr=1&origkw=dc+power+supply&kw=dc+power+supply&parentPage=search
