Merely addressing the impedance matching aspect.
The amp is 2 Ohm stable which means it will handle speaker impedances of 2 Ohms upwards.
Dual 4 Ohm coils can be paralleled hence presenting a 2 Ohm load, so that is fine.
A second 2 Ohm (paralleled 4 Ohm) would have to be on another output else wired in series (2 paralleled with 2 - 1 Ohm; 2 series with 2 = 2+2 = 4 Ohm).
Beware of mixing specs. The amp uses "peak" power which could mean anything.
The speakers quote RMS power which is fine. (Music Power should simply be twice the RMS power.)
Personally I stay away from stuff that does not provide RMS ratings, though I might consider Music Power if certain that is 2xRMS, and maybe Peak Power if they define wtf that is in relation to RMS.
And I would probably avoid amps that have higher outputs with higher input supply voltages - eg, if 14.4V output is higher than 13.8V etc - ie, if a high-power amp looks like a resistive load, forget it.
But others are far better at providing performance comments.
