Thanks for your question. These wonderful sounding headphones are not self amplified.

I'm fairly certain this requires a line-in, non-amplified input. It has an internal amp.

The subwoofer itself is passive, but the channel for the subwoofer is amplified from the main unit. Therefore, you will get plenty of sound out of it with this system, but the sub will not work as a stand-alone self-amplified subwoofer.

No. It is strictly an amplifier unit that requires another source, like an MP3 player.

I plugged mine up to the back of my CB and it was loud enough to hear it at a redlight, 2 cars over with windows up. Haven't tried an amplifier to it.

As far as I know, no. This is a portable, rechargeable, battery amp. Other than that, it functions just like a regular amp.

This is not an amplifier. It takes the amplified sound and distributes it over speaker wire. so the inputs and outputs are just screw down terminals.

No. This unit has no amplifier. It is designed to be installed in a rack system or used with a home theater system so an external amp is necessary.

need an amp of some sort. Be careful - not "these!" Unless things have changed this is not for a pair. When I purchased it was for one speaker only. I just read the other guys response and I have no idea what he is talking about. These are ABSOLUTELY not self amplified.

Yes. Its the Aux setting. You can also plug your phone or iPod into it with an aux cord and play your own music that way

Hi Doug,The portable unit is fairly self-contained. You'd probably need some kind of pre-amp.

No. it is speakers, amp, and a plug in port where you plug in your own music source, such as phone,Mp3, xm using usb

No it is not an amplifier. It only splits the signal to the speakers allowing four sets of speakers from a single source.

It has an optical input. As long as your amplifier has an optical output, that is the best way to go.

Yes. The output can be connected with any amplified device, like computer speakers.

I am afraid the answer is no. This is a pre-amplifier, therefore it does NOT amplify the source. In fact, in my experience, it even weakens a bit the source signal (which I think it should not do either, but it happens). Otherwise, it is an excellent device, solid construction and well featured. Hope this helps.
