Setting the gain correctly

[>>SQL<< 10+ year member]

With my JL Audio amps setting the gain with a DMM is easy as Jl tells you exectly what voltage to set it at.

SO with my new RF amp I downloaded the manual and here are the instructions for setting the gain.

ADJUSTING GAIN

To adjust the gain setting, turn the amplifier gains all the way down (counter-clockwise).Turn the source unit

volume up until distortion is audible and then turn it down a bit until the distortion is inaudible.This will be

about all the way up on most source units. Next, increase the amplifier gain setting until adequate volume is

achieved. Rockford Fosgate source units do not distort, so the volume can be used at maximum setting.

NOTE:Best signal to noise and dynamic range are realized with the gain at minimum. Most users find

adequate gain and volume is achieved at about halfway in the adjustment range.

ok - not real helpful at all.

Amp is a RF T10001BD

Birthsheet is around 1,500 watts

I am running my subs at 1 ohm

What should I do?

to simplify, should I set the gain using the DMM to 1,000 watts (its rated output) or 1,500 watts (its Birthsheet) or somewhere in the middle?

yes I understand all of that.

Just wanting to know if should set to 1,500 or 1,000 or somewhere in the middle.

You can set to the birthsheet, maybe slightly lower.

I think I am going to set it to 1,000 until I feel more comfortable with my Honda's electrical.

You are a smart guy. You always set to the lowest common denominator if you want your equipment to last.

What subs r you running? If the subs will handle it run it a little lower than whats on the birthsheet although you should b good to rated power.

12" Skar VVX's

They are rated at 600 RMS but everyone says they handle much more power.

Youll need some upgrades to run 1500 ie ho alt,wiring.

What of your amp is making the ac voltage before your hu is at the voltage set on the amp?

Ex:

Amp goes to 4v

Hu goes to 5v (supposed unclipped at full volume, benched and at full does 5.5 with my dmm)

Put amp on full 4v and the hu says its putting out 3.2v but the dmm reads that the amp is making full power.

Sqroot (90x4) = 18.9

So simple form amp (set on full 4v) is doing 19.4 at 3.4v from hu.

Is that set alright or should I set the hu lower and match the amp lower to like 3v?

Anybody? Thoughts or explanation why it's like that?

no need to upgrade ho alt for 1500w bro maybe wire and thats maybe.

i been running 5000w at .5 ohms on the amp with stock alt and 2 batteries with no issue for a while, so if you know what your doing your good.

anyways op why nor invest i a DD-1 is super fast and easy plus you will set gains like a pro.
