Looking at the specs, that amp is badly underpowered.
Per channel into 4 Ohms: 55W RMS x 4 (14.4V at Ƈ% THD+N)
Per channel into 2 Ohms: 85W RMS x 4 (14.4V at Ƈ% THD+N)
Bridged 4 Ohms: 170W RMS x 2 (14.4V at Ƈ% THD+N)
With those speakers, you want 100W RMS @ 4 Ohms per channel (so 2) for the splits, and 300W RMS @ 4 Ohms for the sub. You're better off getting two amps IMO, one mono amp that can supply the sub and either a 2ch for the splits or 4ch (probably better, so you can bridge, or expand to include rear speakers).
If you wire it all up, it'll work fine. But once you start putting load on it, the amp will struggle (things like clipping). Imagine a standard fuel pump supplying fuel to a boosted engine.
