DMM can put you in the right ball park, other than that you need a o scope or DD1 to truly know

Google is your friend. An oscope or digital multimeter will let you set you're gains, and at 2 volts hu id use one to set gains.

There are plenty of tutorials out there on how to set gains.

Other than that use unclipped undistorted volume level, no bass boosts, and be easy on your gains if you don't use one of those instruments.

A dmm is safer than oscope if you don't know what your doing in my opinion, but either way, listen as you tune with those instruments because your speakers could distort or your system could clip before your reach the desired instrument reading.

I don't use any headunit settings I leave everything default my treble at 0 my bass at 0 and my sub volume at 7 is all default and how do I match my volts on my amp to match the headunit and what the hell is my sub sonic for mine reads 55hz to 155hz I ain't touched it to kno what it do and I keep my low pass at 40 do I need to bring it up on my subs

 

[calebkhill 10+ year member]

Low pass needs to be at 80hz.

Sub sonic you can leave at 55hz.

As far as matching voltage your going to need a dmm bro.

As to your question about sub sonic filters..... Read this.

CONsealer gasket hides mounting screws and provides an airtight seal

Yea put low pass 80hz, subsonic around 45hz, don't use the bass knob, your amp and subs have plenty of power without it.

Setting your gains is important. If you don't be careful you could blow those speakers.

Sub sonic around 45 ??? lol thats cutting out all the frequencies that matter ...good rule of thumb is 5htz below box tuning..i set mine at 24

No way too know his box tuning. And whether its ported or sealed matters.

I was saying 45 to be safe. He could stand to go lower though

Ok whe u say don't use bass knob do I turn it down and disconnect it or leave it turned up and turn it down not the amp

Go to YouTube and look up xksdle it's my channel and its a bass video and it shows my box

He means the bass boost on the amp ..not the gain control knob itself....

 

[calebkhill 10+ year member]

@NASTY08IMPALA;

The gain control knob mix/Max depends on the level set at the amp right? I've never used one.
