   4x 45W or 2x 90W, yes :) Or 2x45W + 1x90W for a 2.1 setup.
You can change the output configuration in the software. The tools also shows how to wire the speakers if you want to combine two channels to one.

	Right so the channels are bridgable I guess? So either 4 x 35w or 2 x 70w bridged? That's bloody marvelous. Shut up and take my money

	One more question. So am I understanding correctly that the maximum output of any 1 channel is 45w (rms?)? Is there any possibility that you might produce a unit with say 2 x 100w channels and 2 x 45w channels? Would allow for some extra oomph for 2 way hi-low projects =)

	Yes, you can link them wirelessly in a master/slave configuration with TrueWirelessStereo. If you connect your mobile with one of the speakers, press the TWS button on both, they will link and music will play from both.

	That looks like a great solution for 12v rigs! Pretty keen to buy one in the future (when I get back to box building)

	That should be possible, the MPPT point is 17.2V and maximum input voltage is 28V. The charging current is by default 1A, so it would just pull as much as it needs for that 1A charge current. You can not 'overload' it by giving it too much power. I can modify it to a maximum of 4A if that is needed.

	Looks great and very useful. However, I have 100W solar panels (~18VDC (Voc) at ~ 5 Amps. Would connecting your circuit to this panel destroy the circuit? Maybe I should get multiple circuits, lol.
