What do you mean by a sub. output ? Do you mean an output that passes only low frequencies ? I've never heard of this though I guess it could exist. Is it for music or HT ?
Some subs (REL) are connected to the speaker terminals, so all integrated amps would qualify. Some subs only connect to pre-out (RCA or XLR) so you'd need an integrated amp with pre-out (which most have these days).
