I decided to redo the gain setting on my saz3000 without using bass boost. Sub is audiopulse axis

I started to set it using a DMM on ac volts along with an ac clamp meter

first run gain was at min and i got 31.7 volts and 12.89 amps = 408 watts??

second run higher gain-- 79.8 V, 24 A = 1915 watts

another higher gain-- 83.4 V, 25.3 A = 2110 watts

another higher gain-- 84.8 V, 26 A = 2204 watts

after that run the amp shut off.

I checked how much more gain i had and i was amost max. so i turned off the amp, tried it again and i could see/hear clipping

so i got confused 2204 watts and clipping, I got my WT3 woofer tester and did an impedence curve. My clamp meter has an AC current range of 50-60hz so i was testin with a 55hz tone, so i looked at the curve at 55hz and it was 3.1..ohms

This got me thinking should i only be trying to get about 1200watts since its 3.1 ohms?

I decided to turn the gain down below where i could see definite clipping, continued playin and i could smell a smell, not very back coil burning smell, but it was still there. The amp was still cold too.

Before I got ready to post is saw a sticky about gain setting, it was saying multiply rms wattage and resistance of the sub and take the square root to get the voltage output at the speaker terminal, Sqrt(3000x1)=~55V

So that way says 55V. i was getti 84.8 V. So this means definite clipping, right?

all testing was done with a 200amp alt reved to 2k and 2 kinetik 1800s voltage dropped to 12.6 at lowest

so now i have a few questions?

Can i only use tones between 50-60hz if my clamp meter only does between that range?

Should i have factored in teh 3.1 ohms into my first way of setting the gain?

Should i just use the second way "Sqrt(rms x resistance)" to find set my gain?

2204 watts @ 3.26 ohms on your highest power level... yep, you are getting some clipping

From 50-60 Hz your clamp is probably most accurate as it was designed for home AC measurements.

IMO... just set the gains by ear - you have a pretty low distortion woofer, you will probably hear the amp clipping when it does.

I notice somethin today.

Before when i tried to reset the gains with out the use of a bass boost (it was set at half) i just unplugged the remote knob from the cord and went about reseting it. There is a comp today so i plugged it back in just incase i needed to use it, but once i plugged it it and adjusted it to zero. now there is no bass. then i turned it back up to half and unplugged it. and its like there bass boost has a memory of where the remote knob was at even when its unplugged? Is that right?

also its making me think i may have messed up the boost. Like if i set the gain with no boost. and plug in the remote knob with it at half boost, then turn down the remote knob. so now its like i have negative boost. If you can understand my explination.

edit: i played with it again and it seems to just have a memory of where it was. if i turn it down to zero with it unplugged and plug it back in it goes to zero. so no negative boost either. But should it have a memory like that

isn't the knob a remote gain knob?

yes it is

ok..me feel dumb now

lol its all good. once you have your gain set plug the knob in with it all the way up and you shouldnt notice a change. The knob isnt ment for you to get louder but for you to be able to turn it down

i see now. i just alway see ppl calling it a bass knob so bass boost was stuck in my head

most are. sundown and a few other select companies utalize the remote gain knob... in theory it sounds sorta stupid to be able to adjust your gain on the fly but if its a reduction knob like on the sundown it makes perfect sense and honestly could save alot of subs if utilized over a bass boost knob, it just only works as a reduction techinque which shouldn't be an issue in most cases since you would adjust your settings with the "bass boost knob" turned up

i usually dont touch it and just use the eq settings on my deck
