Hey can he hook me up with some white?

Anyway turn off bass boost and find out what your HU preout voltage is.

If its 4v around 1/4 gain if its 2v around 1/2 but no more.

hes always been skinny as ****, he comes over here sometime like ill find him when i get home from school and that ***** sleeps from then untill the next day sometime, whats his deal yo is it the dude hes livin with

let me guess you also had loud on?

and how did your eq look?

 

[Trey803 5,000+ posts]

no its his dirty nig-nog neighbors that think they are rappers he's been hangin out with

i just set it at what i thought was right, it goes like this
gain= around 3/4

db boost or soemthin like that= the same as gain around 3/4

low pass filter= 50 or 60

sub sonic filter= 30 to 35 maybe somehwere like 33

Dude, even with 2 volt preout. Take a look at your gain knob, all the way to the left is typically a 8v-5v input all the way to the right is typically 0.2v. So think about it, your telling your amp to compensate for something like a 1v-.8v input voltage. NOT GOOD.

Bass boost is a waste of time, all it does is boost a certain frequency range usually around 45hz witha 12db slope. That slope also throws some phasing issues into your subs.

If you have a ported box, set the subsonic somewhere around the port tuning frequency, if you have sealed, set it at 20hz. AND set your LPF at 75-80!!! Cross your mids at 80. Basically with a 65hz LPF setting on the subs, you are counting on your front end to take care of 65 and UP, unless you are running a 3 way active front end, don't count on it.

did you set it with a DMM or just randomly set it there?

IMO setting with a DMM doesnt do ****.

you are entitled to your opinion, but I set mine on heavy sustained music and it has done beautifully.

nothing is better than actual numbers. If I am playing music and set gains with a dmm and the heaviest music I listen too, then the only more accurate way would be with a scope(which will still be off depending on what your signal is.

i have no idea hes beeing stupid, i guess that is why hes been sayin like he doesnt feel good, do you know how much he does it. and yea i have a davd player now not the pioneer

I'll argue with him. How many people know their TRUE output of their amps, cause all these people with Hifonics are setting with a DMM and not taking into account the way Hifonics rates their Amps? Do they really see

Also, are people setting them with just a DMM? Or are you using a test tone? What sensitivity was your test tone recorded at? How do you know the amp still isn't clipping? Are you going to trust the Manufacturer to tell you when it clips? I wouldn't.

Unless you are using the PROPER test tone, and a O-scope. This little "set it with a DMM boner" is worthless.

yall say a multi meter as in like a just a voltage meter? i have a few on them

Dude, music is dynamic, you will NEVER avoid clipping/get potential from the amp while playing music.

all an o-scope will tell you is when the output signal begins to clip. It has the same flaws as the dmm method, but the dmm will tell you what the output is in A perfect situation.

dynamic yes. but why set gains on a tone when music will never reach that signal level????

if you use a heavy sustain bass note from actual music, then you know you are at the limits.

edit: and then WTF is the point of having a woofer if you aren't going to play music

What flaws are those? Amps are rated with a Tone, so if you put a tone on it, and use a O-scope, you know where Clipping is.

Music will almost NEVER push a amp into clipping if you use a tone to set the gains. It may for a millisecond but that's the nature of music, it's constantly changing.

 

[dennit469 10+ year member]

well **** all i was sayin is ti was burning haha nothin about it sounding bad or sounding maxed out, it sounds very good and not maxxed out, its also in a ported box if that help, not a very good box cause i made it but its decent

oscope will be the most accurate

Okay, but you people are arguing that with a DMM you are setting them to precision. "You can't argue with physics" well, you aren't using flawless methods. 100 bucks says one day you put a song in there that hits harder than that one. It doesn't have to be a continuous beat, but it just has to hit harder in parts.

You can't possibly tell me that you know the frequency of your "song" will affect the other sub bass frequencies properly.

Also, what bout a front end amp? Am I gonna put a song in my 3 front stage amps that will play a continuous voice? or drum constantly playing.

I'm just saying, unless you set your gains with a DMM alll the way, using all the proper methods, you might as well not bother. you will either over drive your amp, or never get to hear it play it's potential.

you set your gains with a tone and see if your system is balanced. setting with a 0db tone as most tell you is ridiculous seeing as music will never reach 0db signal. if you to it this way, then the amp will never put out the rated power.

the flaws I speak of is that the input signal will change over music and both the dmm and scope depend on that input signal level to determine voltage(dmm) and clipping(scope)
