Could you guys tell me if I'm going in the right direction. Here's what I plan to power...

2x Morel Tempo
Impedance: 4 ohm
RMS: 80 watt

1x SSA DCON subwoofer
Impedance: dual 4 ohm
RMS: 300 watt

So for my amplifier, I was thinking about getting a 4-channel with a power total of 800w. I would bridge two channels for a total of 400w @ 4ohm for the subwoofer and use the other two channels @ 4ohm with a power of 100w each to power the speakers...

If the above is correct, something like this would work right?
One
Two

I'm open to amp recommendations if those aren't up to par...
Thanks

 

Should work fine. Between those two amps I'd personally go with the HF
