Fairly dissapointed.. help plz

[imaspaceguy90 10+ year member]

My setup is a

Power acoustik 2100d

a 15" Re Mt

and 0 guage wiring

and a pansonic HU

a 3cuft box tuned to 32hz

and the big 3

I hooked everything up, and it sounded pretty good but im fairly dissapointed that its not really that loud. I know the Mt wont give full potential til laobut 3000w but ive bdogs ols setup with a SX hybrid and i think it was a lil louder than my MT.

I think one of the reason is because i am having trouble tuning my amp. I tried setting my gain using an a/c voltemeter but the meter never went above 2.0v never got to the 63 volts i calculated. Can anyone give me any advice on setting these 3 knobs on my amp?

subsonic (below audible) should be set around 20-25hz, depending on what you can not audibly hear anymore. Freq, just set it all the way up, play some rap with some deeper vocals, and turn the knob back a tad past where vocals aren't heard anymore through the sub (generally what I do). Then just set your gains alongside your head unit's volume, there is a gain setting tutorial on this site, so that should help.

no, you should estimate where about 60-80hz is and put it there for the frequency knob.

i tried folowing the tutorial but my a/c voltmeter wont register it, i should be gettin 64v with a 35hz tone, but im only reading around 2v, i have the voltmenter set to Volts-AC

How much port area do you have? You should have got a 12" with the room you have....

mmKay...

The subsonic should be like a half-octave below the tuning frequency of your enclosure to prevent overexcursion below the driver's playable range (which is dictated by the box).

Subbass becomes localized around 80Hz. Anything above that and you'll easily tell where the substage reproduction is coming from. Where is your front stage high-passed at? You're going to be looking for the point where your substage complements you midbass and the rest but not overlapping it dramatically or missing a big frequency gap between the midbass and the substage.

My $0.02.
