for christmas and my birthday i got a bunch of money and decided i would like to start learning about car systems. i started looking around tonight and seen some jl w3 12". subs // i read that a 2 channel amp would power 2 speakers and 1 sub. i was wondering if this is correct?and if a 4 channel amp would power 2 subs? what are some perfect amps that would power these 2 subs?
