Why is my sub making this noise

[ThxOne Premium Member]

Ok I will do I need to turn off subsonic and low pass filter.

No but set the low pass to about 80hz

And set the subsonic 2-3hz below the box tuning.

I am using my factory stereo with a passive line out converter and I am using a skar IX-12 and I am over powering it by 100 watts

x2 on trying to avoid using anything like bass boost.

What kind of LOC do you have? You might want to get a LOC that's powered that has a gain on it. Does your passive LOC have any kind of gain on it? How many channels from the radio are feeding into the LOC?

Do you have any tips for properly tuning my amplifier

Turn it down once it starts making noises like that.

You may have already mechanically broken that woofer.

I would start off by visually inspecting the sub. Play those same songs while looking, listening, and feeling the box and sub. I have fixed a few boxes that became loose that sounded just like yours. On another occasion it was a loose magnet that sounded like that.

The Dayton Audio sub I’m running will make that noise when I over drive the sub also. Your pushing it past it’s mechanical limit. It sounds like metal rattling on metal….because it is. You’re probably pushing too much power to it and also sending a clipped signal to it. That’s the death rattle. You should be panicking to rush and turn down the volume any time you hear a sub doing that. I almost broke my leg running for the gain knob when my Dayton made this sound.

My Bl sounded exactly like that when the spider came off the basket. It only became loud when pushed hard and it was loud. Coil tap was different... Sharper more metallic.

Id bet its one of the 2.

Hard to tell on a cell speaker.

I was over powering it and turned off the bass boost and it is not making the noise thank you for all of y’all’s help

This is exactly the type of thing that causes a person to upgrade. Turning down the bass solved the problem. So….What sub are you going to get next?

Thinking about a Rockford P3 or P2

Id run a S.Qubed sub for the money or an American bass

American Bass is legit at a reasonable price.

Anytime a subwoofer makes noise like that, it’s due to something either hitting the cone (leads etc), coil bottoming out, failure of a glue joint (spider, cone, coil to cone etc) etc. Seems to me this is a perfect excuse to upgrade!
