I'm needing to connect a subwoofer to a stereo receiver that doesn't have a subwoofer output.
I know the most obvious way of connecting it is to use high-level (speaker) cables (ie speaker cables from receiver to sub, then speaker cables from the sub to the main speakers), thereby ensuring the sub manages the crossover between it and the main speakers as well.
But... can I use the pre-out of the receiver to drive the sub as well? The problem here is that it the pre-out is necessarily paired with a main-in, and is currently looped (ie, designed to allow the insertion of an equaliser or to use an external power amp). I was wondering if I used a Y-connector on each channel, thereby ensuring the pre-out/main-in connectors are still looped while also providing additional RCA outs (one per channel) to run to the sub (which has stereo RCA inputs).
So... 1. would this work and, if so, 2. which option (using speaker connections or the hybrid line-level connections) would be superior in terms of sound?
If useful, the receiver is a Marantz SR4320, and the sub is a Veoldyne CHT-R10
Many thanks for any advice...
