Too much Bass, mega rattle!

[Pritchard]

Since fitting my new gear im a little disappointed, in the sub. not because its weak, but now the vibration is just too much, that it outplays the speakers.

if i turn the sub right down, so thats its kicking out much less bass than the BOSE, i can still hear a really bad rattle.

annoying.

obviously, something has gone rye since the install.

 

so, iv spent a good hour today in daylight on all fours on the passenger and drivers seats looking around for all the possible loose plastics and found qute a bit that looked like potential rattle hotspots.

 

iv just been to my local park and ride to turn up some bass - and it 've pinpointed almost all, if not all, of the rattles to one spot: the sub enclosure.

 

so the Pioneer sub it fitted where the BOSE was. there are 2 main rattles, firstly the plastic cover (the big A3 sized piece with BOSE badge. )

and secondly, the entire sheet of metal.

 

if i take off the cover, and then push with my hands on the flat metal surface around the sub, it stops. all rattles, gone.

 

 

anyone else had this issue? somehow i dont think dynamat will cure this one, i need to apply quite a bit of pressure to make it stop.

 

 

i have searched this subforum for vibrations, vibration, and rattles, but i cant see anyone else complaining of this.

 

bad install?

Try tightening the bolts that hold the metal plate in place, might be as simple as that

[Grundy]

Change the amp settings?

This is why I think a lot of people who upgrade their sub, put it in a new location due to the plastics.

but it alldaboutdat bass boutdat bass, no treble!!!

ah, i didnt realise that plate was detachable. that could well be what it is.

 

i'm which case I will remove it and re-apply tighter with some soft sponge in the contact points. see if that doest the trick.

Does anyone know of a how-to to remove the plastics from that area? Or can advise me on a step by step?

i dont want to start breaking clips or anything.

 

thanks in advance.

You virtually need to remove most of the plastics just to expose the plate

[BulletMagnet]

Here's a guide how to get to it from across the pond (read it in front of a mirror )

Move the the to its own enclosure in the boot. The stock location is unpleasant when you have more bass as it kicks in the back of the drivers seat.

[BulletMagnet]

I like the bass kick in the back, saves me buying a Mercedes S-Class with massage seats

[Wasso]

Nothing wrong with a bit of tight bass in your back.

 

I've got 600wrms on tap but my sub is only 300, so my gain is right down. So tempted to upgrade.

[spursmaddave]

A Zed isn't the greatest for mega bass or SQ due to the roadhouse and poor build, lots of rattles & buzzes... just crank it up and forget about getting it perfect

[Pritchard]

i am afraid I cant turn it up and forget about it. the rattle literally outplays the speakers. its that bad.

 

at very, very low sub gain (i.e, its set to like -20db on the headunit) its so low that i cannot feel the bass at all while driving. but my speakers are blarring out loud tunes. and yet all i can hear is rattle rattle rattle from the sub enclosure area.

 

 

i'll try and get a video of it later, not sure how well a mic will pick up the noises but ill try and upload.

As stated in my earlier post, the OEM sub enclose is crap for an aftermarket sub. Seen various threads about people recommending putting in the boot.

Video isn't going to help us track down the rattle, you will either need to

- Track down where the rattle is coming from

- Remove the plastics and mod the housing to accompany the sub

- Tweak the Amp settings

[AliveBoy]

chuck the sub in the boot, there's a reason 90% of people do it, get an under strut brace enclosure and it will look smart, sound great and you won't lose too much boot space

[Wasso]

Or do what I have (well Octet had done) as I bought his kit.

 

Get the OEM Bose Plastic Facia - cut the centre piece out. Cover it with Speaker cloth. No more rattles.

[BulletMagnet]

Or do what I did and stick a Bazooka Tube in the OEM location

[Stutopia]

If you tighten everything up and it's still resonating, might it be worth dynamatting the shizzle out of the whole space?

[un1eash]

Under strut is the way forward...

Not sure if this will help mate but i run the same set up and it bugged me no end when i installed it and had rattles in the end i removed the lot and Dynamated all the sub area and the metal around it

it removed all the rattles and made it sound 100 times better i also Dynamated the doors ect with what i had left over and it just made the whole system sound better
