Will raising the voltage input mess up the x-overs?

[havok_19k 10+ year member]

The voltage input on my amp is nowhere where it should be which is 49 volts(1200watt rms at 2ohms). Its only up about 1/3 of the way. Which sucks because it defeats the purpose of getting that amp in the first place. I mainly listen to rock so the low pass and subsonic filter(if that matters) are adjusted to the voltage its runing now. If I were to raise the voltage to where it should be. Would it mess up the cross-over settings and cause distortion and need to be re-adjusted or would the settings hold?

Thanks alot for the help.

What kind of amp? Are you secure w/ that 1200w @ 2ohm spec? (is that at 14.4v? 12.6? 17v?)

I don't think gain settings will affect x-overs.

It's a Phoenix Gold RSD1200.1. 1200RMS at 2ohms. I'm almost 100% sure that it isn't rated at 14volts but I'll call and double check with PG as soon as they open for business for the day.

this is not the purpose of an amp.....gain shouldnt be used as a volume knob.....

1/3rd is a safe measure to have your gain set.....use the output voltage from your head unit instead.....the higher you raise that gain is the more liable you will be in experiencing engine noise....do you have a preamp by the way????

Unless otherwise specified (like w/ JL amps), I always assume power ratings to be at 14.4v. I always adjust my gains to anything from 12.6v (to be safe) to 13.8v.

So, what voltage are you getting out of the amplifier?

I have a Mustang with the premium Mach 460 and I used a line output convterter so I couldn't really adjust the output voltage from my headunit. But yea, I was gonna turn it down a bit after I got it to 49volts to be safe anyways.

Well I just talked to Mr. Phoenix Gold and he said that the amp is rated at 1200RMS at 14.4 and that if I were to turn the gain up to 49Hz the low-pass will hold up and wouldn't need re-adjusting and that the LPL44 is a gain adjuster and not a bass booster, which was another question that I had but didn't ask on here. So if my bass is so loud that it drowns out my highs then I could turn it down. Or set up the main one to where it doesnt drown out my highs but and turn up the remote knob when some clown pulls up next to me thinkin his craps the best in the world..... Thanks for all the help!

I would set the gains on your amp with your remote gain set to max. Then you back down the remote gain to achieve proper SQ. And, as you said, you can crank it back up if you want to show off.

The main thing is that you don't want to be able to turn up the remote gain so high to introduce clipping... that's why you set it to max, then adjust the regular gain on the amp to 49v.

Yea.. That's what I was gonna do. Thanks man.
