Dont do it, that brand is a cheap JB HIFI brand. And that amp has 45W or 40W (cant remember i saw this ages ago but didnt comment) which is the same as any headunit around these days, most are even more at around 50-55W so that amp is basically a waste of money as you'll get the same power output from your headunit to your speakers. Im guessing you will be using two of the channels to bridge the sub, which is only 150W bridged, you might aswell fork out for a better amp with higher bridgeable power as your going no power from that at all. Also 600W sub isnt that powerful, what car do you have? if you have a SMALL car 600W will be ok, if you have anything bigger than a charade or barina or corolla you will want something quite abit stronger.
Not trying to be negative, just letting you know!
If you want my tip, go for Pioneer, Soundstream or Alpine all a bit more dear but you will reap the benefits! Keep us updated on your install!
