    Re: Troubleshooting DMM not reading voltage

    @mylows10 ; @LBC ; @dunerider650 ;

    Alright guys, I tried it again with the subsonic filter set to 5hz (lowest), LPF set to 400 (highest), bass boost at 0, and gain was at exactly half. I tightened down the DMM's leads into the speaker wire outputs. The head unit was at 50/62, loudness off, no EQ settings, etc. The bass knob was all the way up. I played a 0dB 50hz 192kbps (only bitrate available) sine wave from realmofexcursion.com that I downloaded to my iPhone. I set the DMM to AC volts. Reading = ~ 00.21 volts. What am I doing wrong here!?

    Use a cd. Download the SMD DD-1 disc and use track 1. 40hz at 0db. Burn it and use that. your iphone has to be the problem. It has a volume and gain of it's own.

    My head unit doesnt have a CD player. And I'm using the USB cable with the iPhone, not the 3.5mm jack, so I thought it wouldnt matter?

    I put that realmofexcursion.com file on a flash drive and tried it again. All the same settings as before. Read: ~ 00.29 volts

    yeah, I watched it. I unplugged the 4 channel's rcas (left the mono's in though of course). Loudness was off. All EQ settings were flat. No bass enhancements. I'll try it with a 60hz tone, but I didnt think that part mattered.

    Ok, so I found a different website. I downloaded a 705kbps 60hz sine wave in .wav format. I tried it and I am still getting the same results as before.

    When it's hooked up normally the sub plays the music perfectly fine, so I dont see how it could be an amp related problem.
