Which Pre-amps Will Allow Two Subs

McIntosh preamps have 3 outputs as well.

First Sound Presence Deluxe Mk II has two sets of outputs as well...

The Pass Labs X0.2 have two pairs of variable XLR and two pairs of variable RCA. All usable at the same time with its single volume control or remote. The Pass X1 and X2.5 have one pair of each type that are variable.

I use my X0.2 with multiple amps and will use it with active crossovers eventually. Works simply and flawlessly.

It should be easy to use the RCA connectors for the Subs on any of the units. Remember that on preamps, the RCA outputs will have a lower output than the XLR, but almost all amplified subs have output controls on them to compensate for this little bit of difference.

Also if you ever run a Theater preamp through it, all three of these have a unity gain pass through for that purpose.

Hope that helps.

To answer a question, I guess I'm looking at the subs as a left right channel thingy (technical enough). To everyone else, thank you so much. I have one of those 300b amps with a volume control. My speakers are not full range as they are single driver crossoverless design. So the next tier of additions will be a pre-amp, followed by a subwoofer. But since I was going to get one sub, shouldn't I make sure I get the ability to run two given that so many claim that 2 is noticably better than one?
