Aragon 2002 Pre amp to a Monitor Audio subwoofer


I have never used a sub with this setup but am doing so now. Can I use a 2 male to 1 female Y adaptor on my preamp out and run a single RCA to the subwoofer?
Or do I need to run 2 RCA's out? I know it is a monaural signal. My Monitor sub does have 2 inputs - but if can can use one RCA - that be be mu choice.

Thanks

I can't find any reference to such a preamp. Are you sure you got the model right?


I thought the Aragon 2002 is a stereo power amplifier, No?
DO NOT use a 2 male to 1 female Y adaptor on preamp out and run a single RCA to the subwoofer, IT WILL DAMAGE THE PREAMP!

Connecting a preamp and power amp to a subwoofer:

Or use a pair of RCA ’Y’ adapter on L and R output of the preamp:

use 2 pair of RCA interconnect cable, one pair to power amp inputs, another pair to subwoofer line inputs.

Sorry - The power amp is the 2002. The pre-amp is an Aragon 24K. Hope this helps. Thanks for all the help!
I am assuming there are two pre outs,   run one pair to the amp and a pair to the sub.  You really dont want to tie the left and right preouts to each other .  Let the sub's crossover sum to mono.
If the pre has a single pair two "Y" adapters are required for each channel.   Connect left and right to the sub just as you would any other component.
