    2muchbass is correct....

    first off - MONO block. MONO meaning ONE.

    if it has 2 channels, it only means there are 2 sets of terminals where you can connect speakers, both internally connected to one output.

    MONO blocks can have one OR two channels. it doesnt matter, its a monoblock.

    edit: and Kaezoo is also correct because the specs on the site would suggest it was a 2 channel amp

    All mono car amplifiers have 2-channel inputs, because many head units only have 2-channel outputs. This allows you to use the amplifier with a head unit's front or rear outputs or a 2-channel non-fader output, rather than just a mono subwoofer output. The input signals are summed into a single channel at the amplifier.

    If the amp only had a single input, and you wanted to use it with a head unit that only had a 2-channel pre-amp output, then you'd be stuck connecting to either the left or right channel or you'd need to find another way to sum the channels before connecting the amp.

    It's also very common for a mono amp to have two sets of speaker terminals, because they're often used to drive multiple subs.

    Edit: looking at the Sony amplifier specifically, I believe there's incorrect information on Sony's web site. While it does say it's a mono amp, the power specs are clearly for a 2-channel amp, and the picture appears to show left and right speaker outputs with a "bridged" diagram. I believe the amp you're looking at is a 2-channel amp, not a mono amp. http://www.sony.co.in/product/xm-gtx60212

    It might support to know what amp you are dealing with. Actual 2500w 2 channel amps are just about non-existant, however quite a lot of more cost-effective manufacturers will advertise VERY inflated peak scores like that. The boss cx1250 for illustration has a 1250x2 max ranking, but simplest makes use of a 60A fuse indicating is genuine vigour output is someplace round 600w rms or 300w rms per channel. 90+% of the time a pair of excessive vigour subwoofers can be run with a mono (1 channel) amp. Some thing just like the hifonics hfi1500d, for illustration, produces 1500w rms at 1 ohm giving a pair of dual 4 ohm voice coil subs 750w rms each and every.

    The amp has one one input (left and right) and one output for bridging purposes, the reason there are four terminal instead of two is because usually when using a larger amp, you tend you use lower gauge wire, and it sometimes becomes a problem if you try to run two woofer on the amp. Not because the amp cannot drive it, more as in space for the cables to connect to the amp... so many manufacturers make a four terminal connections on the outside but effectively they are joined on the inside so it is mono just with a different connection block. Hope this helps. Goodluck

    It means you dont have to splice/cram a bunch of wires into one terminal. You can use the second set of terminals to run multiple subwoofers. The 2 "Channels" are as one, internally connected, an extention of the first set of terminals. Thats all it is.

    Actually walmeis, it only has one input and one output. Its a mono block amp...

    You too are wrong Dr + mrs bears face. It only has one (1) input and one (1) output. It even shows it in the picture if you google it...

    It means that the amp can accept left & right inputs from your stereo, and use both of them to produce a mono subwoofer output when configured in that way. It's not an old model, and it's not very unusual.
