Hello all,
I took electronics in ’89, but I still remember a lot, and still know how to solder. That being said, what I want to do is build a cheap circuit board for my car. The purpose is so that I play audio from my laptop over my car stereo speakers. What I imagine as the final product is a stereo cable from my laptop to a stereo connector on a circuit board. From there I will need to amplify the signal to play over the car stereo speakers. I will control the output with my laptop. My speakers are stock so I only need 4 to 8 watts. I plan to splice all the speaker wires coming out from my car stereo, and soldering them to the circuit board. From there, there will be some kind of auto-switch that will automatically switch to my laptop input when a signal is detected, and then switch back to car stereo when signal is absent. Cool huh. This sounds like it will be a lot of fun, and hope it won’t set me back any further than about $20. Your help will be greatly appreciated. Thanks.
Paul
