i'm not sure what you'd be happy with but i sugest shopping around for used amps cause you won't spend as much and as long as they work you'll be good.
i got oe speakers a 12 pioneer 200\500 watt sub(if found on garbage day 4 years ago it had a crack in it) that works great and a pheonix gold 500watt amp together it sound like i paid alot of money for my system but i actally paid $10 bucks they guy thought the amp was broken

the remote connection was damaged the radio is an el kameleon my wife bought that $100 it was on sale.
just keep you eyes open and you might find a good deal.
