Raised my gain a lil and dam

i always had my amp gain set to about 25% up, becuase i was always afriad sence i always here of people blowing thier shit up setting gain to high. but i was feeling a lil riskey today and decided to crank that mofo up a lil to about 65%, cus thier still under warrenty. and holy shit my head was about to explode //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif now im tempted to put it up even higher, this a bad idea? i know yall will yell at me if i do... i tryed reading your guy's gain turotial, but it confuses the hell out of me.. whats the average amplifer gain set to about? i just wanted to tell you all my story, and that my head really hurts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif peace!!

i wouldnt do that anymore...some gain knobs are a lot more sensitive than others, and you're really risking your shit by doing that. post your amps RMS wattage and how many ohms they're running at, and i'm someone here would be more than happy to tell you what to set your gains at.

head unit is deh-1400 2 volt pre-outs

subs are 4, 4ohm subs wired to 1 ohm.

amp is directed 1500d pushing 1200rms at 1 ohm

thanks!!

follow jl's tutorial or set it at 2v on your amp if youre gonna be sloppy about it. just remember gain doesnt equal volume control.

god i feel retarded lol, first off my amp has no volts on it, it just says gain, second i tryed reading jl tutorial, but dont know how many volts to set it at, and i do have a volt meter... and im not any good at match so if somone cold tell me that would be cool...

Sqrt(Power*Resistance) = Voltage

its easy dude...

turn your gain to 0

turn your hu up about 80%

start turnin the gain up till it starts distorting

k so when my gain is set, do i keep the bass eq, loud, etc off? and keep it on flat?

This is basically how I set my gains. Sometimes I'll use a test tone cd.

Here's another thought to add. Since you say that your amp doesn't have gain markings and that you don't know much about setting gains, it's possible that where your amps previous settings were may have been equal to around 4 volts. (just an example) If your hu is 2 volts, then your previous setting would have made your output quieter. Turning up the gain MAY have put it closer to 2 volts which would match the hu. (Which is one of the main purpose of the gain anyway.)

That would help explain your dramatic increase in sound. If your speakers aren't distorting, then great. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

sometimes its hard to hear distortion. i just matched my hu's voltage on the amp and turned it down a lil more just for safety.

So how would you know you matchted the hu's voltage and the amp?

Set it to 35 volts
