properly setting gains is jus a waste of time //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif lol

into speaker wire terminals. make sure they are secure. turn DMM to the red voltage thing (atleast it is on mine) and turn the gains till u get the proper voltage output.

im having problems....i put the black lead in the neg speaker terminal and red in the positive terminal.....and then i play a 0 db 50 hz tone and i'm getting a reading of about a hundred somethin that fluctuates all over the place and doesnt change when i turn the gain knob......anyone know what the problem is?....and also what range do u put the meter on.....theres 1000, 200, 20, 2000m, and 200m

Did you set it for AC voltage?

Set the range to around two whole digits, if it's not auto-ranging...

Something wrong with the DMM? This is weird.

 

[walkychalky 10+ year member]

ok...well my dumbass was using dc...so i set it to ac and i got the gain set up.....but how i do i set the ssf and lpf?.....how do i measure where they're set?

i usually ahve a shop set-up my amps when i get a fresh install so ive never done this b4....and since im simply swappin out amps i dont wanna take it to a shop

If yer good, use your ears and common sense to calibrate your system.

SSF

ported? near min. because the lowest is 15Hz.

Sealed? don't need it.

LPF

set it until it stops sounding boomy.

 

[walkychalky 10+ year member]

im ported n tuned to 32 Hz so should i just keep it min?....is there any way to measure what its set at?

 

[DBfan187 5,000+ posts]

play a 32Hz test tone @ a low volume, turn it up until you it starts fading away.
