Rear Subwoofer

Hey look what I found!

Appears to be a horrible paper cone 8” / 2 ohm woofer. Going to attempt to replace it with another 2 ohm with a high sensitivity and see if it helps at all.

Have a JL 12” in a flat box going into the cargo cutout, but would prefer to just use this if passible.

How much clearance for the back of the woofer?

would this work with a 5.3:" depth:

My bad - The mounting depth is only 2.66" for the Rockford Fosgate P3SD2-8 8" Dual 2-Ohm Punch Series Shallow Mount Car Subwoofer.

Optimized for both sealed and vented enclosures {Sealed (Vb): 0.25 cu. ft. (7.0 Liters) / Vented (Vb): 0.75 cu. ft. (21.2 Liters) / Mounting Depth: 2.66 in. (67.5 mm) / Cutout Diameter: 7.13 in. (181.0 mm)}

Finally had a chance to post a pic of the finished product. Hid the amp in the space that the factory “sub” was in. 12” slim JL box fits perfectly in cargo cutout. Sounds amazing.




Juuust fit - used Velcro to attach on the bottom so I could remove if we need to.

Barely fits but it does.


Bass knob mounted under parking brake. Juuuuust fit.

How do you secure the JL box inside the cargo hold ?

It’s quite heavy and fits rather snugly. Added Velcro to the bottom as well to add some additional grip.

do you get a lot of rattle from the storage compartment cover? Or did you just leave that off?

Nicely done! I have a quick question for you. Where did you get the input for your amp? I'm assuming you used the two wires from the stock sub, but what did you use to lower the input to preamp levels to then feed into your amp?

I have that same subwoofer (had it in my last car), and I'd like to reuse it. I'd need to buy an amp since I left the amp in my last car since I didn't feel like ripping everything out.

My main concern is how to best to feed the subwoofer signal into the amp. Can you explain how you did it?

You need a line out converter. Something like this would do the trick - https://www.bestbuy.com/site/audioco...lack/5873400.p

Yup it’s this sub - https://www.crutchfield.com/S-pM2ebH...112LG-TW3.html

After having it for a bit - I don’t enjoy it as much as a more standard rear firing sub with a larger enclosure, but it’s excellent for the limited space that it takes up.

Thanks for the info, I was jus looking at couple of powered sub from Crutchfield, one sealed and one ported, according to the their tech the ported will sound better but the problem is both are out of stock.

Be real careful on the dimensions - the one I have baaaaarely fits.

I’d prefer the separate sub/amp setup but I see the appeal of a combined.

Saving for sale some day. I’m sure you can buy one from a third party Acura parts reseller.

Hi Joe,
The Sub I choose with built in amp won't fit the space, I think I will go with your set up but when you say you don't enjoy it as much, could you please explain what's wrong with this setup, is it too much bass ?

Yeah its really good for the space/cost.

Compared to a more traditional (larger) sub enclosure, the bass isn't quite as tight and you don't feel it quite as much.

If I didn't need the 3rd row as much - I'd definitely go with a more traditional enclosure with more volume in the box.

I found a fuse under the drivers side dash that say Active Noise Canceling, I think removing this fuse might work

Did you ever get a fix to the ANC problem? I'm thinking of upgrading my system in a similar way.

I got the Tech package so no sound camera and mine work fine, maybe you can rewire the camera to another power source so you can remove the ANC fuse, I am also curious cause usually camera and ANC should have their own fuse.

Hi - Bumping this thread to see if anyone can tell me how to remove the carpeted subwoofer baffle/cover. I tried to pry it off with a trim removal tool but it’s not budging and I don’t want to break any clips. Thanks for any tips on where I should pry to get this baffle off. Thanks.

You need just disconnect ANC and you’ll be fine
