Hi all, first post, so please be gentle with me.
I have been doing a lot of reading ready to build my first (of many hopefully) speakers.
I'm looking at building a 2.1 speaker.
My question is, apart from using a 2.1 amplifier.
How would you wire these 3 speakers to a 2 channel amp?
I understand using xovers to separate the spectrum, but would the sub go on the left channel or the right?
Or is there a way to connect across both channels with the sub? or is this only possible if the amp is bridgeable?

The best and easiest route is to run your 2.0 from your main amp and use a sub amp for your .1 subwoofer. These can be very inexpensive and provide the control you're going to want.
An alternate route is to use a 2.1 amplifier, which just combines a subwoofer amp with a full-range amp for the satellites. The Dayton MCA2250 is a pretty good, cheap one, if a little underpowered.
The next best route is to use a dual voice coil subwoofer. In this case, you'd use a passive crossover for each channel. Each crossover would feed a satellite and one coil of the subwoofer. While entirely possible, this option is undesirable because large inductors and capacitors are required, which could end up costing as much as a sub amp that would be much more effective.

Thanks for the reply Dan.
So with the separate amps, the 2 amp inputs would be wired together. Would the sub amp be mono then?

Hi Richard,
The easiest and best way is to use a separate subwoofer amp, and line level inputs. This lets you use DSP on the sub only, while leaving your main speakers as audiophile-clean as possible.
Of course, this is arguable, but if you spend a lot of money on a DAC, you usually don't want to use another digital conversion process in the loop.
Parts Express does sell a 2.1 active plate amp, but the total output is a little limited. Probably best for small desktop systems.
Best,
E

Here is the unit I was thinking about. 50W on the bottom, then 22W on each side.
Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier

This sub with some efficient full range speakers would work with the suggeted 2.1 amp.
Tuba 18 <---This sub is awesome with low powered amps
FaitalPRO 3FE25 3" Professional Full-Range Woofer 8 Ohm <-------These speakers are very efficient

No, with a separate sub amp you don't have to mess with any weird wiring. There are usually accommodations for both line level and speaker level inputs from your main system. If you have line level outputs from your main system, you use those. If not, you run speaker wire from your main amp to the sub amp, in parallel with your main speakers. The R and L signals are combined in the sub amp and the sub is fed a mono amplified signal. It's very straightforward.

Thanks for the replies everyone.
I think I get it now.
The outputs will go to the 1st amp for the main speakers and then either low level or high level outputs to a 2nd amp which would combine the left and right channels and filter out the highs
