I am totally new to the car audio scene. My sound has always been from the engine. :-) But, with the daily driver being a 2.2 S-10 now, I am starting to mess with the audio. Just a few real beginner questions. - 2 ohm vrs. 4 ohm. One 'better' than the other? I assume the 2 ohm will draw more from the amp? - dual voice coils. What is a voice coil? And whats the deal with dual? thats all I really see advertised. I will bring out some more questions as they come up and I dont find the answers. Thanks Ken H.
