yeah 240 watts of sphincter power. Whenever you buy car audio, you get what you pay for. I bet if you hook that legacy amp up to a meter it would probably only register about 50 watts TOTAL, if your lucky. Take my advice, stay clear of that amp and buy yourself something descent. If you look around I'm sure you can find an amp for 100.00 that will out perform that legacy in every aspect by far. If you need some help let me know; I've had many competition systems and I'de be glad to give you "GOOD" advice. As far as hooking up the sub once the amp is allready installed, all you have to do is connect the speaker wire to it; very easy. You might as well just wait untill you have the sub because hooking the amp up without it is serving no pupose cause your door speakers are allready running of your head unit. So when you get both then go to the shop, they won't charge you any extra to hhok the sub up. If they do, they are trying to rape you.
