Is the Big 3 necessary?

[SpiderX1016 10+ year member]

I have an Audiopipe AP1500.

I checked battery voltage at idle with gain all the way down. 13.8V

I checked battery voltage at idle with gain knob at 3/4. 13.8V (with spikes of around .2V)

I checked battery voltage at 1,500RPM with gain down. 14.2V

I checked battery voltage at 2,000RPM with gain knob at 3/4. 14.18V

So, Is the big 3 really necessary?

The lights never dim even if I put the gain knob at max. I might as well do the big 3 but I was just wondering.

Gain knob at max??? oh boy....

two questions, do you know how to set a gain? and do you have a load/what impedance.

he might've just been testing to see if the lights would dim...maybe.

Ok... I meant Remote Gain Knob.

answer other question please.

2 Subs (4 ohm DVC) at 1 ohm.

do the big 3

if you aren't dimming with 1500 watts I don't think you're getting the full draw, any batts in the back or anything?

Nope, everything is stock.

Power wire and ground wire to the amp are 4 gauge. I set the Gain at 31.62VAC or just a little lower than that.

at 1 ohm that's just under 1000 watts so after box rise you aren't even running 1000.

someone correct me if that's wrong but the chart is SQRT of RMS x Impedance = Voltage so I used Voltage x Impedance^2

hmm, I only used 1,000W X 1 (1 ohm) = 1,000 then I got the square root of that, 31.62VAC.

So I would need an Amp Clamp to calculate Box Rise? Then take that resistance and set the Gain again?

you don't really need to know for sure what your rise is, but now it makes sense why you don't really dim, but do the big 3.

Is it ok to leave the gain like it is? Cause I'm fine with it.
