what the heck, here goes- subs can produce voice sounds but shouldn't. subs are made to boom. if you are feeding voice frequencies into it, you are wasting power, because your inside speakers are supposed to be playing your higher frequencies. a crossover, as mentioned above, directs the right frequencies to the right speakers. a high pass crossover allows frequencies hiigher than its set point to pass, and a low pass cossover allows frequencies below its set point to pass. a combination of the two, allowing a narrow range of frequencies to pass, is called a band pass.

you can place subs in a trunk because low frequencies are omni-directional. however, to hear higher frequencies you need to be inline with the actual driver (speaker), so even if voices were coming out of your sub, you wouldn't hear them.

inside your car, speakers are paired left/right. front left/right and rear left/right. the sound front to rear is the same, but there are different sounds coming from your left and right speakers, so you would never run 1 speaker, it would be in pairs. you could get away with only using fronts, as you sit in the front.

the common way to send information from your head unit to your amp is via an rca, or patch cable. just like the 3 cables to hook up vcr's or video games (the red white and yellow ones) without the yellow. yellow is video. you will still need power, ground, and a remote turn on lead for your amp. The turn on lead also comes from your head unit.

I really like crutchfields for buying audio equipment. name brand stuff, excellent customer service, great shipping and you can learn tons from their little tutorials.

anything else?
