I\'m planning on 8, If it works, clarity and control, its right on the limit though so may end up at 2,
At 8 Ohms the amp would just cruse, hardly get hot but will be wound rite up.
As for the Jaycar amps I have not personally had much to do with them, however I would not go there myself, I have to be able to back up products I work with if that makes sense,
Funny story, supposedly fusion come out of the same factory as sound magnus, I haven\'t looked much into it however.
1 ohm is close to a dead short, While It may run down that low I have seen plenty of 1Ohm Stable amps die with constant use, comp use e.t.c fine, crank as much as you can, but think about it as a sub moves the Ohm\'s change, a 4 Ohm sub may vary between 2 to 6 Ohms, where do you expect 1Ohm load to go.
