Bass Roll Off?

[kb1824]

Goodmorning Guys,

I have a 2016.5 Mazda Cx-5. I noticed this since I got the vehicle but never really pursued any insight into this, well now I am. When I increase the volume on the headunit, the bass rolls off or should I say it completely gets dampened or erased. Thus, the higher the volume the lower the bass. Why is that?

Also how can I correct this, is there a specific setting I should use on the equalizer to get the maximum bass or so out of the headunit when the volume is completely maxed out?

That's Bose for ya! They do some strange things with their hardware.

Turning off center point makes the bass seem more pronounced.

Yeah, turn off CenterPoint. In my opinion it hurts the soundstage.

This. Turn off centerpoint

Also, FWIW, I stuffed the subwoofer with denim insulation and plugged the port to eliminate the 'boominess" (one note bass). This wont help with bass output but the bass will sound better.

The roll off is actually evident in many factory systems too. Same thing with the '16 Civic I traded in. I also turned off centerpoint and modded the subwoofer. Both really help the output.

This is a DIY guide that details how to reduce the "muddy" bass from the Bose subwoofer mounted in the spare tire. This fix has been done by many others on this forum (originally jgriffter, followed by PTguy, jmeitz, Zoom49, greggmischenko, and others). I recently did the same mod, and I just...

Where is this Center Point, is it in the equalizer settings?

Hey Guys, the other question I have is, as stated before my head unit is non bose. I have a sub and amp connected using the PAC AOEM-MAZ2, however should I have connected the RCA to the front speakers or the rears? I connected to the rear speakers but most of my signal I believe is coming through the front, as explained before, when the volume increases most of the bass is gone and all sound mainly comes through the front, hence my subwoofer doesnt really thump as it should. Maybe if I connected the module to the front speakers, I would get more output from the subwoofer.

What do you guys think?

CenterPoint is a Bose thing, no Bose, no CenterPoint.

@kb1824 check your fader settings make sure you haven't manually decreased the volume on the rear channel. As far as I know there is no power different front to rear if the stereo is set to the center.

Thank you, I will check

factory systems have a roll off to protect their speakers from blowing. That low end can build and become harmful cause its so dynamic.

I’m swapping my system for kickers and keeping the stock head unit (I retrofitted for CarPlay), so I’m getting a LC7i to help bring back that low end. I would recommend it. And if you haven’t, an amplifier for your speaks! I’m grabbing the kicker key200.4
