class d amp with possibility to connect subwoofer

A single sub?

I would stump up the extra cash and get a minidsp 2x4 and the amp of your choice with separate power supply.
With that you are open to a lot more possibilities in the future as we all get twitchy eventually!

I'm sorry I cant recomend an amp as I have three tpa3116 2.1 boards and none are worth the bother tho I'm sure good ones do exist.

minidsp 2x4 price is 100$ - I will consider that, but I think that for 100$ or more I might find some better amp with pre-out for sub.
