One transformer for multiple amps?
I'd like to build a six-channel amp with three of these kits. Do I need a separate transformer for each amp or will a single transformer suffice for supplying current to each amp?
The Velleman 30 watt amp kit requires only 12 volts and 2 amps to perform within it's specifications. If you desire to run multiple amplifiers, you can buy or build a large power supply and power multiples. If you power supply was 10 amps output then you could power 5 amplifier kits.Good Luck

Can this product run off a motorcycle battery?thanks
It would probably need a pair of them at least. You would stack the batteries in a series string and tie the center to ground. Otherwise it would work. The power would be reduced somewhat. For full power you would need about 33 volts DC, round about. I'd also suggest you take a closer look at some of the other amplifier modules, this one is a bit too minimalistic for my tastes.

Do you sell something to power this amp?
Yeah, I think I found the part you need. (see below),Any 2x12V or 24vct transformer should do.

I just ordered 2 Dayton ND90's. I have read conflicting info on this amp output (not on this site), can these speakers handle this amp's output?
Yes, the ND90s should do just fine with this amplifier.

Can we bridge two channels into mono to support more power?
No, this unit is not designed to operate in a bridged mode. Doing so would most likely damage the unit, and void the warranty.
