Tuning a crossfire vr4000d

Just wanted to make sure everything is right. I'm running 2 15" hdc3. 2000 watts a piece. I checked the gain with my dmm.

my settings go like:

lpf in on

crossover frequency is about 135 hz

subsonic is on

subsonic is set to about 35 hz

and my lpf is set at about 100hz

does this look right. I think my lpf should be lower. I have a constant 13-14.4 volts and its still good at full tilt. Subs sound alittle peaky and at volume around 35-40 I am still smelling the glue on the subs.

 
yeah I will lower my llpf to 80.

the box is tuned to 37.77 hz, so should I still lower the crossover frequency?

Why would the subs still be smelling to at higher volume?

 
$1 a watt rule
yes sir....I'll even give it to ya for .50 cents a watt....//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

and thats at 12 volts:D....if you want to run at 14 volts, add 20% to the bill

the sub smells? Could be excess glue burning off. Lower your SSF to around 25 or so, that would probably work.

37.77x0.75=28.375

try 28

I gotcha....is thats the formula to set the ssf? Subs were just reconed so it is possible...no scratching:D

is there anywhere good to look for tuning amps? tutorial?
