wuzzzer Posted December 30, 2023 Share Posted December 30, 2023 Your sub doesn’t have high level inputs so you’ll need to get some kind of box that converts high level inputs to RCA outputs. Quote Link to comment Share on other sites More sharing options...
1MoreFord Posted December 30, 2023 Share Posted December 30, 2023 What amp/receiver do you have? Is it lacking subwoofer pre-outs? Quote Link to comment Share on other sites More sharing options...
babadono Posted December 30, 2023 Share Posted December 30, 2023 Can you say voltage divider? I am going to guess at 10k input impedance(cannot find a spec) so try 100k in series with the input. Quote Link to comment Share on other sites More sharing options...

pnort Posted December 30, 2023 Share Posted December 30, 2023 rather than tapping amp output, consider tapping the crossover's bass output. Quote Link to comment Share on other sites More sharing options...
babadono Posted December 30, 2023 Share Posted December 30, 2023 This commercially available product claims to do what you need: https://russound.com/products/audio-systems/multi-room-controllers/expansion-devices/adp-1-2-speaker-to-line-level-adapter#product_images it is basically a voltage divider. It has such high values of resistance that it will not change the load seen by your amp. You will then have to use the Low Pass control on the sub to limit the frequencies to the sub. And the volume control of course. Personally I would just build my own, but that's just me. Quote Link to comment Share on other sites More sharing options...
