Seadoc Posted January 1, 2023 Share Posted January 1, 2023 Need a little advice on connecting 2 subs to an amp with no sub connections. Speaker connections A & B will be for front and rear. My new/old woodshop stereo. Pics attached for clarification. AMP = Yamaha A-1020 Subwoofer 1 = Yamaha SW-4 Subwoofer 2 = Klipsch R-120SW Quote Link to comment Share on other sites More sharing options...
billybob Posted January 1, 2023 Share Posted January 1, 2023 Yes, see the amp has pre-outs. 1 Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted January 1, 2023 Share Posted January 1, 2023 Depending on how that Yamaha is configured you might have to run an RCA cable into each sub and back again, which is why the Yamaha has those jumpers in its Accessory send and receive pre-amp section. Since your subs only have pre-amp ins, here’s options for you: - Get two RCA y splitters, connect each to the Send portion of your receiver. Connect one side of one of the splitters to the input of one sub and the other cable to one of the Receive inputs on your Yamaha. Do the same with the other sub. Or - Get new subs that have both pre-amp inputs and outputs. Connect the subs inputs to the Send portion of your receiver and connect the subs outputs to the Receive portion of your receiver. Or - Get a new (used) receiver with a dedicated sub output. Or - Just use the one sub you have that has high level inputs and outputs and connect one of your pairs of speakers to that. 1 Quote Link to comment Share on other sites More sharing options...
