Thread: Good site to learn about car audio?

I'm looking for a site that can give me a better understanding of car audio. There's a lot of terms that I've heard, and kind of know what they mean, but I don't know how it exactly works. Such as: bridged amps, the effects of wiring in parallel/series, ect. I know a little about how ohms affect the wattage and resistance, and things like that. Does anyone know any sites that explain things step by step, preferably with pictures/diagrams?

Thanks
