Hey,
I am new to this home theatre stuff....I got a question for ya.

I have a Jvc RX-5032 5.1 receiver and at the back of it, it has the subwoofer output, is that the same as a pre-out of a head unit in the car and only puts out 2 - 4 volts?

I'm not the best to answer a tech question like this but I think you are right. According to the manual of my Aiwa AV 95, the sub out is 5 volts. I believe the signal bypasses the amp just as in a car stereo. Gene

Yup - it'a a pre-out to take to a subwoofer, that usually has it's own built-in amp.

Not exactly. There are subs without amps. These are called "passive" subs meaning they need an external amp. Usually you would plug the front speaker wires from your receiver into the back of a passive sub and it's internal crossovers would then be used to split the signal and send them to the correct speakers. These type of subs are used with the in-expensive HTIB's.
