    So, I'm currently in the process of setting my gains for my 4 channel amp and mono amp. I've been researching on how to properly set your gains using a digital multimeter, and it seems like every forum and website tells you a different way to do it. The SSA forum stood out to me and made the most sense about gain setting, but it still left me with a few questions.

    My first question is should i set my gains for the 4 channel amp first or the mono, or does it even matter?

    When i set my gains for the 4 channel amp i will be using a 0 dB 1000Hz test tone, but what i'm not sure of is what settings should i use for my head unit? A lot of people say to set everything to 0. I'm just not sure.

    Than when i set my gains for the mono amp, how should i set up the head unit. Bass Boost all the way up? And Subwoofer control all the way up? or opposite?

    Also what volume should i have the head unit at when setting the gain?

    odd...

    I've never seen actual resistance measure nominal resistance.

    But even at that reading, wired in parallel should be 2.0-2.1, not 2.5.

    What size wire u usin?

    Try a minimum of 10 awg wire and try to keep the run no longer than 6ft and see if that helps.

    I'm using 12 gauge wire. ii just retested with the coils wired in parallel and im getting exactly 2.0ohm. i dont know why it was reading 2.5 before but things seem fine now.

    thanks for the help

    retest.

    First, touch probes together and see what they read then subtract that from what the coils read.

    I retested each coil this morning. i touched the probes together and i got .1ohm. one read 4.1 ohm which is perfect and the other was reading 4.2, i guess thats ok?

    i have one dual voice coil 4 ohm sub. i wired it to 2 ohm. i checked the resistance with a DMM and the read out i got was 2.5 ohms. is this normal?

    also when setting my gain should i use the formula 500 watts x 2 ohm = sqrt (1000) = 31.62

    or should i do 500 watts x 2.5 ohm???
