I didn't include any pictures of it all back together because it looks just like it did before I took it apart! The center console fits over the top of my box just like it did over the bose. There's

Or you could do what I did - Sub floor mounted 2.5 cu ft subwoofer box, Alpine Type-R 15", uses a minimum of under seat storage area.
 
The box fit right in front of the fuel tank and after covering it with fiberglass and undercoating it looks almost OEM (and you only see it if you crawl under the truck).
 
Obviously a major fab job including cutting a 12" square hole in the floor but I thought someone might find it interesting.
(hole was framed with 1/4" steel and is much stiffer even with no box mounting than the original 20awg flat steel in this area. Upper and lower box sandwich the frame and clamped with 12 bolts).
Sounds awesome and will massage your brain out if you put on rap music. Funny thing is I'm all about hi fidelity and usually listen to light jazz, but I tend to get carried away with things.

I just read this and am I right to read that you cut a hole in your floor and the box is on the underside of your rig?!? Wow

Yes - I guess its been in there a year now and I've had no problems at all, sounds great and can still store a lot of stuff under the passenger side. I've been hot rodding for years so it was just a typical fab job for me, but I have to say

if you brought it into a custom professional it would be a very expensive project. When its time to sell the truck I will just build a sheetmetal plate and bolt and seal it in you'd never know it was there unless you pulled the back seat out and pulled the carpet up and even then so what ? It will be a 150k mile truck when I sell it and it won't even mattter. I'm super happy with this solution.

 

Here's a pic of the cabinet before it was mounted underneath the truck. You can see it has been shaped to fit around the fuel lines on the frame rail side.

This may well be one of the more impressive things I’ve seen in years. Well done! Best solution award goes to you!

The best thing I ever did for my sound system was install full sound deadening my vehicle, from roof to floor pan. full CLD & LLP doors to floor, during my install I also covered the factory Bose sub with CLD...

 

and sitting in the rear seats, the Bose sub is really pronounced.

I did 3 high power 8s on 2400 rms. They freaking slam for what they are. 

Lifted back seat 2 inches, box is 1.94 cubes net at 33 I think with a 6" aero port

That is a solid box. I did the lift c bracket thing because the downfiring box I have was too to the ground for the excursion of the skars. I think a front firing box would be so much better !

a few days, R&R interior is time consuming, but its far more work to "correctly" install the CLD & Foam &  LLP... but worth it. 

 

also I didn't really show it but the doors are full CLD on the inside skin and inside frame.

Ended up buying the center console box off ebay with the kicker comp 8". I haven't sold my 10" single box that goes under the rear seat yet, but ebay had a 15% off coupon so I decided to buy it. Here's a few pics of the install. I haven't wired it to my amp yet cause I have to remove my backseat to get to it. It was a little hot outside today with a heat index of 108 so I'll finish tomorrow. It took me about an hour and a half to install cause I was taking a few water breaks.
Here's a few pics of the console removed, the stock Bose sub, the new box with 8" sub next to the stock Bose, the 10" sub I removed compared to the others, and the new 8" installed before I put the console back in.42f7e3b4ad8232a97da7487c130bbc63.jpg4e492859dc2316718c9b7a9f9ccd8898.jpg5364e65ad4729206f569de094d742408.jpg3e2cbcd96c831a1522b3241cd33f116e.jpg

Did anyone ever provide dimensions on the simple wood box from OP? 

I would be interested in this as well.  Want to upgrade slightly from what the Bose system gives me and would really prefer to keep the rear under seat space.

Thanks. Sub was $200, Amp was $110 and probably about $50 between wiring accessories and plywood. Total of $360.

I recently finished up my Bose Subwoofer replacement in my 2016 LTZ. I felt the Bose Sub was very underwhelming. I considered the Kicker option made specifically for the Silverado, but didn't want to give up the floor space. After removing the center console and lots of measuring, I came up with a box design to work with the JL Audio 8W3V3-4 8" sub. This sub requires a volume of 0.30 cf. short of making a fiberglass box, I'm convinced there is no way to get any more volume from a box that fits under the center console (with no modifications to it).

 

I added an Alpine MRV-M250 amp to power the sub and mounted it on the back wall next to the factory amp. Also got the remote for the amp which is mounted inside the large storage compartment of the center console.

 

It sounds absolutely amazing, exactly how the factory high end system should sound! You can feel the bass in the seat, something that never happened with the stock sub!

 

Here's a few pictures.

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.

      Seems to be Missing a lot of Updates

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.
