Nevertooloud427 Posted April 12, 2019 Report Posted April 12, 2019 So I’m getting no output from my subwoofers. Brand new pioneer deck and brand new audiopipe 2k. I have 2 d4 12s wired to 1 ohm and that’s what it reads at the amp when the car is off. But when I turn the car on it reads -2 or -3ohms so that’s obviously why I just don’t know what to do I’ve tried everything. Tried 3 diff sets of rcas
Mike4068 Posted April 12, 2019 Report Posted April 12, 2019 You'll get a negative reading when there is power in the circuit. Not sure why your subs aren't playing.
slowfkncar Posted April 12, 2019 Report Posted April 12, 2019 Some solid state amps are known to shunt/energize the outputs when turned on. your subwoofers total impedance is 1 ohm, if you aren't sure then unplug your woofers from the amp and measure impedance again. Make sure your getting signal through the rca's, if you absolutely cant get any sound and your woofers/wires/signal checks out, it points to the amp.
Joshdashef Posted April 12, 2019 Report Posted April 12, 2019 When you take resistance measurements there should be no load present. if it shows up fine with the speaker terminal outputs disconnected your fine man SMD Tool Map (2024): https://www.stevemeadedesigns.com/board/topic/226545-smd-tool-map-2024/ Great Box Bracing Examples: https://www.stevemeadedesigns.com/board/topic/202148-best-way-to-brace-a-box/?do=findComment&comment=3055002
Joshdashef Posted April 12, 2019 Report Posted April 12, 2019 Just thought of this. I was moving my amps around and bumped the master slave switch so instead of master it was set to slave. No output at all until I realized after almost shitting bricks that all I had to do was set it to master SMD Tool Map (2024): https://www.stevemeadedesigns.com/board/topic/226545-smd-tool-map-2024/ Great Box Bracing Examples: https://www.stevemeadedesigns.com/board/topic/202148-best-way-to-brace-a-box/?do=findComment&comment=3055002
Nevertooloud427 Posted April 14, 2019 Author Report Posted April 14, 2019 Really? That’s interesting.. so if there’s power in the circuit thats Why it will read negative. I don’t get why my subs won’t play then? Literally if I turn the bass knob from nothing to full I can feel the subs get power more as I go up and stop when it’s off so I feel like There getting signal, but no output at all

Was a satisfying fix and bass session afterwards lol Build Log: http://www.stevemeadedesigns.com/board/topic/152954-1998-plymouth-neon-updates/
