Pelihagen Posted March 19, 2019 Report Share Posted March 19, 2019 Hello, I just bought a 2-Channel amplifier to power my new SPL tweeters. I'm a bit confused on how I should use my DD-1 to set the gain properly though. From the manual: 5. Using included harness, connect DD-1 to output of amplifier. Connect the red harness lead to the Left Speaker (+) terminal, connect the black to Amplifier Ground. (Note: Most multi-channel amplifiers have the signal on Left (+) and Right (-). So I put the positive lead from the DD-1 to the Left Speaker positive, and the negative probe into the negative power connection on the amplifier? Can I just stick it in the 0 gauge negative, like if I were testing voltage with a multimeter? I just had to ask here to be 100% sure, don't wanna blow anything up. 😝 Quote Link to comment Share on other sites More sharing options...
Joshdashef Posted March 19, 2019 Report Share Posted March 19, 2019 Uhh my manual says this "5. Using included harness, connect DD-1 to output of amplifier. Connect the red harness lead to the Left Speaker (+) terminal, connect the black to Left Speaker (-). " Not amplifier ground, I have no clue where you got that from Quote SMD Tool Map (2022): https://www.stevemeadedesigns.com/board/topic/220267-smd-tool-map-2022/ My Port Size Calculator (in progress): https://www.stevemeadedesigns.com/board/topic/217087-port-size-calculator-in-progress/ Common Port Walls for a Slot Port: https://www.stevemeadedesigns.com/board/topic/217076-common-port-walls-why-it-matters-to-your-box/?tab=comments#comment-3240313 Link to comment Share on other sites More sharing options...
