FI BTL 12, Fully Loaded. Clicking sound on High notes. Whats going on?

[ChevyFI69 0]

Runnin an AQ2200d, Alpine 9584 head unit, tuned in a 2.2 Cubic foot box to 31 htz. The clicking noise only occurs on a sudden knock of bass & Is repetitive in fast bass lines but only in high notes. In low notes it does perfect. Whats goin on?

i had this same problem with my fosgate power hx2 on a saz1500. from the conclusion i came too it was from getting the coil to hot to soon. after hours n hours on multiple days of playing with my amp gains i finally got it to stop

[ChevyFI69 0]

Im guessing i need to turn the Gain down some then. It doesnt do it right when the sub plays. So its making some sense now. lol. I should turn the gain down & not up? right?

[NDMstang65 403]

You've got some interference in there some where..some how.

Speakers just do what the amp tells them to do..

[ChevyFI69 0]

So where should i start? by turning the amps gain down? the bass boost is completely off. BIG 3 is donw on the 105 amp alternator & Running an optima red top under the hood & A HC800 In the back. Where the world to i need to start?

[NDMstang65 403]

Is your RCA and power wire ran on opposite sides?

Turn the gain down and see what it does..

[ChevyFI69 0]

yeah. theyre on oppostie sides. like i said man it only does it on high note. like on dorrough wired to the t. the fast knocks of bass it does it. sounds like its breaking lol. Imma turn the gain down & see what it does.

[NDMstang65 403]

Another thought..

How high is high? Where do you have your crossover set?

[ChevyFI69 0]

Im gonna say around 45 htz. & im not sure about the crossover bro. Where should it be set at?

[NDMstang65 403]

On your amplifier it should be low passed at around 70Hz or so..

[ChevyFI69 0]

alright. ill be sure to set that. It doesnt do it first when the speaker comes on though. only about 5 mintues into playing time. like it gets hot & Starts to do it..

I'd set the lpf to around 80hz

[NDMstang65 403]

Sounds like you are clipping the piss out of it to me. Have you smelled coil?

[ChevyFI69 0]

No coil smell at all. It only does it when the speaker heats up.

[ssh 924]

No coil smell at all. It only does it when the speaker heats up.

even if you put your nose in the port?

lol well of course then. But i mean the amps set perfect & it only does it when the speaker heats up! ughhh i need someone to tune it for me lol

I agree with Nick, it sounds like your clipping it. Depending on how much clipping is present, will affect the time it takes for the driver to heat up. Did you set your lpf to somewhere around 80hz?

And subsonic filter is set where? and gains set be ear?

Is your RCA and power wire ran on opposite sides?...

[ChevyFI69 0]

The power wire & RCA wires are ran on the opposite sides. The power wire running down the driver side & The rcas down the passenger side.

[ChevyFI69 0]

Im gonna go in today & get everything set. where should the subsonic be set?

You're not supposed to smell heated coils.

I said that because it's a myth, you can't get noise interference that way.

It's probably burning off excess glue, nothing bad there.

[SubSam 21]

Could maybe be a simpler problem... sounds dumb but how well is the driver secured to the baffle? If its not bolted in I've heard some funny frequency-specific sounds come from stripped thread screw holes and small gaps around the surround. Tee nuts + teflon tape never fails in that manner.

I'm just trying to think outside the box... no pun intended

[tejcurrent 13]

My first thought was make sure it's secured properly. If your box is single baffle or not braced screws can break or the sub can come loose. Also if there's even a slight gap where the sub isn't seated properly air can escape at louder volumes and make awful noises. I'd check that first. If not that definitely look at your amp settings.
