gains up, sub not pounding

[dennis09x 10+ year member]

So i got a stetsom 2k6d and a re xxx 12" new model wired to 4 ohms. So possibly ~2100 watts or so. Gains are all the way up on the amp and the HU eq is all zero.

Only way i can get ANY real thump is if i turn the HU sub level up (which i believe is just a built in gain knob).When i do turn the level up to high, the clipping light comes on, on the amp.

2 runs of 4 gauge to the rear, 100 amp alt.

The amp has 4 gauge for power input and i have a deka batt up front and kinetik 2400 in the rear.

Voltage shows drop from 14.3 to 12.7 at volume 28/35 (no bass boost) with slight clipping on musical highs on late night tip. Pretty good output at that level, but horribly low output below 20/35 without bass boost.

And horribly low output on any other song that isn't super bass heavy (rock, pop, metal) without bass boost up.

gonna go buy a DMM and check some shiz.

any advice on what to check, where to start, any solutions...etc...

thanks for taking the time to read and any help you can give me...thank you.

HU sub level must be up.. Turn the gains down, set everything on your HU, then set the gains on the amp with a DMM.

recheck all your settings and make sure the coils are wired correctly

yeah if your sub out isnt all the way up then ur not getting full voltage from the preouts, its not the same as adjusting the bass on your HU

you have to max out every setting on your HU and amp to hear anything

also try grounding your amp to your gas tank

yes but with the gains all the way up.....you shouldnt need the full voltage from HU sub out

Do you have a subwoofer setting on the HU? And why not 1/0 wire with that kind of power?

nvm u dont get it

I know, ill be looking into the wire as the problem. cause max consumption for AWG 4 gauge is 60 amps, and this thing can draw 140 amps on high music. Would lack of power cause a clipping signal? i thought all it would do would put it into protect...

So you dont understand why having the gain maxed on the amp could cause a clipped signal..?

Is there any reason you think you need the gain all the way up?

Just set your gains with a dmm...

did you read anything? or just post based on title?

so, put the HU sub level up ( it can go from -15 to +15) to +15, put gain down. Set EQ. Then set Amp with DMM. Then turn down sub level???
