I'm using two mono blocks running one pair of speakers and this is
connected to a cdp. The mono blocks have volume controls so there is
no need for a pre amp. I want to add a sub woofer and would like some
advice on connecting it to this setup. Thank you...

If you get a passive sub, then you would just run the speaker wires to the
sub and then from the sub to your current speakers. I can't think of a way
to run a powered sub without also adding a pre-amp.

Are you using separate amps for some sort of audiophile purist
reasons, or because that's what you happened to have lying around?
Once you add a sub bass unit, any idea of accuracy generally flies out
the window, so you might as well add a preamp so at least you can
control it properly :-)

Several higher quality subs (e.g., REL) have high impedance
speaker level inputs on them. You simply connect the speaker
level inputs on the Sub to the speaker output terminals of the
amps (i.e., in parallel with your speakers). You then can adjust
the level and low-pass crossover points on the sub to properly
blend with the main speakers.

I see 3 possibilities:

1 - connect the subwoofer between the amplifiers and the existing
speakers. Most subwoofers have that possibility (speaker level
inputs).

2 - use a Behringer DCX-2496 Ultra-Drive Pro to split the low
frequencies to the subwoofer. It will be easier if you chose
a subwoofer with two line inputs but most subwoofers have that.

3 - More simply, you can buy a universal player (DVD-Audio, SACD)
(for instance the Pioneer DV-575A in Europe or the DV-578 in
the US) which will split the low frequencies to the subwoofer
and connect to your existing amplifiers.
