just to be sure i did it the right way...

HU settings to zero (loud bass/sub...all that crap)

HU volume to 3/4 (which is 30 for mine)

All knobs on the amp all the way down.

Play a bass heavy song (three 6- posse song)

Turn the gain knob until distortion is heard- back of a touch till it disappears.

It's the enclosure. Yank that X out of it and build a new one asap. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

would poly-fill work the same? i don't wanna drive nails thru my box if i can help it.

Polyfil is used when the box is too small. It 'tricks' the sub into thinking the box is bigger than it really is.

I definitely agree that you should put the Type X in a 2 cu ft sealed box. You will probably get less stink from it that way, but only because you won't have fumes coming out of the vent. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
The smell could be a little residual glue melting off, or it could be a sign of too much power -- which is definitely possible with your gain setting method.

2 cubes sealed is way too big for an X sub, IMO. Way too big...

Either purchase (or borrow) some fancy *** equipment or turn your gains down a tad more once you hear audible distortion -- keep in mind that audible distortion with a subwoofer comes at a considerably higher level than with front stage speakers -- so instead of backing the gain off a touch, you may need to back it off two touches.
Or, you could just set the gains so that the sub is balanced with the rest of the system -- but I realize that a balanced system probably isn't your goal here...

why does my 2000wmax 1000wrms 9512 have no problem with max gain on this amp, but the x is bein a little ***** at halfway? i don't even turn up the HU past 20.

edit: not even halfway...

i like my bass low, and this sub i know will do it. actually it has, but i smelled that shit and it scared the fck outta me so i dont even have the sub on anymore. i'm not so much lookin for a balanced system. i want it to knock me outta my seat when i turn it up. what kinda tools are you referring to?

set it with a nice DMM to 1100w, and problem solved. USe a 50 or 60 hz test tone, and set it.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
