Help with gain on Orion 2500d.

[Weece 10+ year member]

Well my problem is my amp plays fine, but i have to crank the amp past 3/4 before i even get any output out of it. I mean it seems like im still getting the 2500 watts but i have to crank it all the way up almost to get that output on a 15" xxx.......i didnt think i would have to crank the gain that much to get output. ANyways i have a optima yellow top battery and stock alt on a 2001 yukon. So im just wondering if its because my amp is getting enough amps from the alternator? Still need to do the big 3 also >

how your electrical system is surviving is beyond me, but did you set the gains using a dmm or by ear?

I used a dmm ....... but im still wondering why i have to crank the Gain almost to full to get the voltage im suppose to have. It was also very hard to set because barely even touch the gain and it jumps like no other.

what voltage is your deck? if it's a 2 volt deck and only puts out 1.5 volts rms or so you'll have to turn it up to match them.

Deck is a 5volt preout. And ive played around with every setting there is on the deck and still have to crank the gain on the amp....im just worried if this is going to hurt the amp over time, but ya my electrical system is barely hangning on....so i plan on ordering like a 250a alt pretty soon.

how many volts you getting at the amp? if it's only 11 volts or someting then you'll have to crank the gain higher to get 2500 watts

i also noticed that you have to play with the other setting by the gain. i had the same problem till i adjusted the high pass and the other nob(can't remember what it's called).

Im getting about 14.2 volts, so i shouldnt have to crank the gain.....but i do to get the full 2500watts.

Maybe check the pre amp voltage at the amp.

intelli Q???

panasonic 5v?

If thats the case it doesn't surprise me.

If you need to turn up the gain, you need to turn up the gain... thats what its there for. This assumes you set the xover and such properly, of course.

At last, we agree! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

You are not going to harm the amplifier unless you are turning the gain pass the clipping threshold, if it isnt doing what it should at 1/2 gain, then turn it up with no harm done...

as long as it's not clipping, the amp won't get hurt

^ beat me to it...

How is the sub wired?

It shouldnt make a difference since the drivers are disconnected when you are reading the output, so the resistance will not play a part on the amplifier.
