the factory subwoofer in my pilot has started rattling and it sounds terrible. What would you recommenced? Any way to fix the rattling? Or Aftermarket sub and amp? Are there any aftermarket subs that will fit in the enclosure area of the factory sub? Also is there a way for me to just disconnect the factory sub at the back of the head unit? I love my bass but it’s just ruining the sound right now, so better to disconnect completely.

Looking in the service manual linked at the main page here, it appears there is a 14 pin connector B with 7 wires on the head unit which has the rear sub +/- in it. Maybe it could be de-pinned.

I have been wondering if there is a way to take these to line level and then into a small amp I could replace the woofer with my own unit. Like through a PAC SNI-35 or something.

Just figured out that the rattle is actually coming from this piece to the left of the subwoofer. Glad to know my sub itself isn’t broken, thank god. But this big armrest / plastic cup holder thing is rattling against the plastic piece being it. If I grab it tightly with my hands and pull it away from the wall I can make the rattling noise stop. Not sure how to make it stop though without holding it

Good find. I like this video from a fellow Piloteer because, as he says, no endless talking.

So for your subwoofer rattling you've got two options:
  1. Practice turning your bass controls down on every song you play just before the bass drops, for example after "and the forests will echo with laughter" on Stairway to Heaven.
  2. Pull the panel out as shown in the video, stuff some sound dampening material in there and when you put it back together make sure you don't have any screws loose. :p

Mine did the same thing in my 2004 soon after I bought it, and they replaced the subwoofer

i have a 2004 LX. I was impressed by the bass
Of the stock subwoofer! My friend has a 2019 c-class Benz and I know my stereo sounds way better than hers!! So I was curious myself what Honda has back there. So I did the research if there was some kind of aftermarket option because I didn’t want to have a box mounted in the back at all I wanted it to appear completely stock. Turns out that every car audio makes a subwoofer for stock locations it’s called
“Shallow Slim” mounted subwoofer and we have a 10” inch subwoofer. You have to take out the small seat in the 3rd row to access the subwoofer in fact the whole panel needs to be removed that’s why temporary taking that little to remove the panel. Turns out that all out speakers including the subwoofers are all made by Alpine, A 50 watt Alpine! So I decided on the Kicker’s CompVT 10” inch Shallow slim subwoofer that Max power is 750 watts. So Any 500 watt mono block amp will work. I installed my amp inside the storage compartment In the back to hide the amp as well. Some might say “there’s no air flow inside the compartment to keep in cool” so I had this genius idea one day and bought my amp it’s own 2 Laptop Cooler! One for the bottom and the second I drilled out a few tiny little holes on the lid then I mounted the second on the compartments lid

Considering I'm halfway through my own stereo upgrade, wanted to share some knowledge.



The factory subwoofer is an Alpine 50W (Max) 10" Subwoofer @ 2ohm.


The inside of the subwoofer/fender cavity (Towards the Hatch):

The inside of the subwoofer/fender cavity (Looking Down):

The inside of the subwoofer/fender cavity (Looking towards the front of the vehicle):

And here you can see the XM Computer mounted on the inside of the fender.


After applying some Kilmat sound deadening.

The most annoying thing in order to remove the rear side panel is the Pillar Panels, on 06-08 models (due to airbags), they use a special clip, that requires you to hit it with a mallet in order to break it. So make sure to pick up at least 2 before starting down this path.

The special clip's Part Number is 91561-SJD-003. Local dealership wants about $5 for each one. Otherwise you can order some via Bernardi ($2.70 each), or you can get 10 from Amazon for $16.99

Here is the inside of the subwoofer cavity (looking towards the front)

As for subwoofer selection, you'll want one that is "Shallow Mount" as you only have a tad less than 4" of clearance to work with. For my case I'm replacing the factory subwoofer with a Infinity Reference REF1000S, which is on sale from Amazon for $89.00. It has a 200W RMS rating, adjustable 2ohm or 4ohm load switch (so I could run it off the factory deck by switching it to 2ohm). It is also designed for Open/Infinite Baffle setups, but thankfully the subwoofer cavity appears to be sealed pretty well, so it will simply the equivalent of a very large (mostly) sealed box. As I am installing an aftermarket deck also, will need and be placing my amplifier under the passenger seat where the factory Nav system would be.

Want to see more of my install? Check out my thread here.
