Default Buzzing 2011 Speakers

Anyone have their dealer give an opinion on these terrible stock speakers and/or door panels? I was just curious because I have never heard such terribleness in speakers before. Would Dynomatting solve the issue? Possibly placing rubber o-rings between the speakers and the door? Every note is like buzz, buzz, buzz, even with the bass set to neutral. My friends '02 WRX sounds light years better. What gives?

I rarely have vibration in the speakers. How loud and what style music are you listening to? Might try getting the stock Subwoofer to clean out the speakers.

I think it's the door panels buzzing. I dropped the bass to -4db. Less buzz, especially with the trance/house I like to listen to.

So a negative bass setting is the solution? That's crazy talk. Mine were buzzing on Bob Seger's Night Moves for crying out loud.

My door buzzes with the stock '11 STi speakers. It's definitely the door/something in the door, not blown speakers. That said, all of it is being ripped out for some nice Hertz Mille gear and sound dampener, at which point I have a feeling I'm going to be hunting a lot of buzzing down with foam tape. If you're staying stock, pull the door apart and start finding what's rattling/buzzing, and fix it.

Orrrrr, take it back to the dealer, and have them fix the rattle. It's a new car, it shouldn't rattle. It's under warranty, get the dealer to fix it.

Some people have reported that their speakers weren't even bolted in to the door baskets. I'd check that, however, there is some resonance within the door panels and small strips of foam tape or 6"x6" strategic squares of butyl sound deadening will help. No need to coat the entire door unless you want to drive a library.

You still gotta pull the door panels to get to the speakers and install they rubbery butyl rings right?

I agree, use that warranty to it's fullest.

Yeah take it to the dealer unless that is a HUGE pain.

If you aren't upgrading, there is zero reason for YOU to deal with fixing a problem on a brand new car.

It's the door rattles, not the speakers. The speakers in my 2011 premium model are actually pretty decent, but I'm changing them out for some more bass and to take care of the rattles at the same time (dynamat type product but cheaper). Got tomorrow off for Veteran's Day so gonna hang out in the garage and have quality time with the WRX

IF the dealer does not solve the issue. Purchase some Ensolite and line the space between the door card and the steel of the door. This should stop your buzzing if it is coming from the door card.

According to people on IWSTI the problem is that a wire was not attached to it's clip properly and that was making the noise. They had the dealership fix it in both doors and now the noise is gone.

The dealer fixed a buzzing in my older forester under warranty. They pulled the door panel off and cut a slit in the weatherproofing which seemed to fix it. Im not one to use my passenger window until it drys off so the slit wasnt a big deal. If it was my driver side window I would think twice since sometimes I have to open the window in rain at drive throughs.

I'll post more details later, because I'm only halfway done with my speaker installs. I installed the front door speakers yesterday and it was pretty easy. I installed Polk dB651's. They came with a plastic adapter/ring that actually screwed right onto the OEM spacers, I didn't have to fabricate wooden spacers so that was a relief. Here's the deal with the buzzing door panels. Take out the white plastic baffles - there are two of them in each door (big one inside the door itself, the other one attached to the door panel). They are absolutely useless and I just tossed mine in the trash. Without them, there is no difference in road noise whatsoever, and rattles are completely banished. So far, the Polks are much louder, with more bass and crisper sound than the stock speakers (which really aren't that bad, they are probably better than what most $27k cars come with). I used a little bit of Fat Mat (cheaper alternative to Dynamat) - real sparingly, just to keep some of the wire harnesses from rattling, but you probably don't even need to use any sound absorbing material at all. Just trust me and toss out the white baffles.

I actually did almost the same yesterday and today. I tore out my OEM speakers (which are HORRIBLE compared to your Premium trim level models, just look at the crappy thing in the pictures below) and installed the Polk db6501's. I bought the sail pods from Subaru for the stock tweeter mounting housing, which took some cutting and jury rigging to get to work with the Polk tweeter. I bought some Dynamat for cheap ($55 for the door kit) and put one large sheet on the bottom half, opting to cover the white baffle instead of taking it out. I could have used less of it, but I had a ton of it I wasn't going to use anywhere else, so I just choose to do around 50% coverage on the top half, and 25% on the inner door, and then went around for phantom rattles. One annoying source or rattle that took me forever to figure out was the white square grommets for the door panel screws. After I covered those in Dynamat, they stopped rattling as well. I also bought some vinyl foam tape for covering areas where wires would come into contact with the door, and to fix the annoying A-Pillar popping over potholes and road humps.

So there is a difference in base vs premium trim levels? I have a 2011 premium and have bad rattles in the doors and the very back panel by the rear window. That things rattles even at low RPMs. VERY ANNOYING.

Do you have a sedan?

This has happened since 2008 WRX Sedan. Here is the fix:

1) Go out and buy painters rags (small rags from home depot, etc) or tear up an old shirt, but the rags are thicker.
2) Open your trunk and hit underneath the shelf and you will start to hear a vibrating noise.
3) Underneath the shelf there is a circle opening in the middle. Stuff rags inside it, a few of them.
4) Again hit the under section and it should sound muffled.
5) If not muffled enough, find other openings and stuff them too.
6) Go inside the car at the back seat.
7) Fold down the rear driver side seat and you will see on the right side the plastic shelf can be lifted from the metal of the car by the latch. Lift that a few mm and stuff (a kitchen knife works well) with rags.
8) Open the anchor latches at the top of the shelf and stuff the perimeter of the latches with rags.

I found that doing all of this fixes the rattle 99.9%. Now the only time you will hear a noise is on those highway pre-toll booth grooves which shake the whole car.

Reif,

Open up your door panels and remove the white plastic baffles (see my previous post). I'm going to try Snow Drift's fix to the rear package shelf next - mine is also rattling. Yes the premium models have better speakers. I will attach pics of them soon.
