Wiring/music equipment question: I have a fairly cheap 30WVox guitar amplifier with a phone/line out jack on the back. When I plug something into the jack, sounds stops coming from the amp's speaker and starts coming out of whatever I plugged in instead. However, I would like it if the sound would come out of both at the same time. How easy or difficult would it be to rewire the amp so that it works this way? I'm good with a soldering iron, but not too great with circuit analysis.

I built this mini guitar amp based on this circuit. But I used a 4 watt speaker rather than the 8 watts specified. What are the consequences of that change? [more inside]

My car stereo was recently stolen. Since all I used it for was to route my mp3 player through the RCA in's, and since I've been kicking myself to start doing some DIY electronics projects, I'd like to make my own amp rather then buy a new stereo. What would I need to do this project myself? [more inside]
