Bass dosent wobble

When i turn it to the 200 top left, at first it was at 2.0 when 0 gain. As I turned the gain up to full blast. The reading was 5.0

Than it started going negative, than it started to read 0 no matter what, that I turned it off than turned it on. It got up to about 15.2. Now it is 0 out again.

Lpf is at 80h,

i tried 50hz tune got nothing, turned to 60 hz tune it made a little difference in the DMM.

Somethin is clearly wrong here

where are your probes plugged into?

The amp is bridged, so I plugged the positive dmm wire to the positive output where my speaker wires were. Than I put the negative to the negative output on the amp. And screwed them down with the allan wrench

U need both probes in speaker outputs ..u mean u have black probe in neg on amp or neg speaker imput

The dmm is connected straight to the amp.. Negative probe to negative out put. Pos to pos.. Basically I disconnected the speaker wire from my sub to my amp and left the wire still connected to the SUB terminals. Than put the probes in the same spots where the speaker wire was leaving from the amp

Is your lpf turned up to accept the 60htz tone

His low pass is at 80

Lpf is 80 hz, just went out there to try again and took this pic of the set up (building a rack soon)

I turned the gain up all the way on the 200 setting and it for once. Stayed at a 20.6 and didnt move (like it did all the other times) Im looking for 34.5 , if bridged the amp is 600 RMS so 600*2 = 1200

SQ is about 34.5 .. So each sub is getting 300 rms.. Or should I do 300*2 =600 SQ = 24.4

When I put the gain at half way. It shoots down to a 6.8

I'm thinking something isn't turned up that should be. Do you have a sub volume on your head unit that increases by. Decibels? If so, turn that all the way up

buy skar, problem solved. then your bass will wobble.

If you are talking about the SUB option, I do have that. But when my subs are on, I don't use the sub option because I thought it was the same as bass boost and people say not to use bass boost?

Will turning the sub option on the HU up, make the volts from my amp turn up as well?

wait, you keep looking for 34.5, what ohm load? 34.5 @ 1 ohm is 1200w, does that amp even put out 1200?

I think ur looking for twice the voltage u should be ...turn sub output on deck all the way up this will let match ur output without cranking up the volume

im looking for 2 ohms.. 600 RMS bridged. 600*2 =1200 SR = 34.5 but im not sure if I should do 600 *2 or 300*2 because each sub will see 300 RMS but together the amp is putting out 600RMS
