First of all, I've been away for away and its good to be back. It looks like I missed a very annoying troll, so at least I have good timing.

Anyway, my birthday is nearing, and I believe I will be getting a new guitar amp. I just have one question: If an amplifier has a wattage of 2x30 watts, does that mean each speaker pumps out 30 watts, or that the amp actually produces 60? I can't seem to find anyone who knows. I'm looking at the one in the Behringer V-Tone line. Help would be appreciated.

Yup.

The amp is rated at 30 watts per channel, two channels. Therefore, assuming it has two speakers, they get 30 watts each.

That amp has 2 internal 10" speakers, so you don't need to worry about actually matching impedences or bridging channels. So yes, it puts out 60 watts of sound altogether, via 30 at each channel.

Hehe, 60 watts, I have a 500 Watt and a 700 Watt amplifier in my dorm room to power my speakers and subs.

And you are not deaf yet? I wish i had a bigger amp. Not quite as big as yours but one with more effects and stuff. Right now i only have a 15watt Ibanez.

I have a 30 watt fender champion and it works well for me.

I will be as soon as I fix the connection between my subs and my amp. FYI, it's a 700 Watt Rockford Fosgate 2-channel amp (700S model), and 2 Image Dynamics IDQ12 D4 V2 subwoofers. Apparently, with a 1000 Watt amp these things will do around 145 decibels in a car (sealed box) so I figure I should easily be getting 115 decibels (concert speaker volume level) in my room.

Get a 30 watt Peavy. Or hey, There are these off-brand amps they have at FYE for $60. They pump out more volume than my buddy's 60 watt Crate.

So basically it's as loud as a 60 watt amp right? I was never sure whether 2 speakers each producing 30 watts would be as loud as a single speaker producing 60. And although it may look like it, I'm not entirely infatuated with volume, this thing has a huge range of different sounds it can produce too. I'm just still not sure about that one fact.

All other things being equal, two speakers at 30w RMS will be the same volume as one speaker at 60w RMS.

The above assumes that all speakers are optimally boxed, all speakers are equally efficient, all speakers are being driven at the power level they were designed for, all speakers are the same size, and that all amps are actually producing the equivalent RMS power levels.

All these things don't happen very often in real life though so you should make your decision based on reviews or actually listening to the equipment yourself.
