OP here. Nice looking build L1nk3d! I too am curious about your LC2i. I just used the line level into the Alpine Amp and I think it sounds really good.... but, now I'm curious!!

 

I would be willing to make some more boxes but am a bit hesitant because as L1nk3d said, it's a very snug fit. I would hate to send one to someone and then it turns out to be 1/4" too long for them! L1nk3d, did you fasten yours to the truck or just relying on the snug fit to keep it in place?

 

Someone asked about rattles and shakes... I don't notice anything unless I turn it up fairly dramatically or if I have some loose change or an empty soda can in the center console area. I wouldn't be concerned about it!

I imagine the line level inputs are fine. Like I said I didn't have the pigtail so I just went that route. It does complicate the 'tuning' but I think your going to get a cleaner signal in the long run. The level matching and bass roll off compensation is what sold me. I still need to tune mine a little more because the bass knob is very sensitive turning it 1 degree yields a huge increase in base, not gradual like I would expect.

 

I was going to weld up some brackets but I ended up just drilling a couple holes for the bolt size in the front bottom to 'align' the box, the the center console just keeps in there. Its so snug the brackets would have been overkill.

 

If I build another one I learned enough to make it fit better I think. But, yes, I too am concerned about sending it to someone and having it be so tight and them not being able to figure out how to get it to fit. I think the design needs a little refinement before I can produce these with confidence.

 

 

I've heard some rattling on VERY bass heavy tracks at very specific frequencies, but for normal listening to rock country pop r&b most hiphop, you won't get that. Keys, change, pens, anything loose in the console is going to rattle. My son left an empty caprisun pouch and IT rattled, but, if your putting subs in your car you should already expect that. Right?

 

I'm going to be addressing any panels that rattle separately, GM is known for that so it's an issue. My exhaust makes certain things rattle too so it's not a big deal for me.

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 t

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

Could either of you touch on how this gets wired up? Is there any issues with it integrating will the rest of the bose setup? I thought I remember reading something about a chiming issue when adding a sub to the bose system

I haven't had any issues. The LC2i or speaker level inputs get patched into the sub output from the bose amp so it should already filter out unwanted freqs. I have had the door chime on while listening to music and haven't noticed any anomalies.

 

There is a good YouTube video on where to patch it in. Its a Blue wire with grey stripe and Grey with Black stripe for sub out. It matches the connection at the factory sub.

 

Power, and ground are also easy. Power is a little hard to get through the firewall but if you take your time and follow what others have done it's the hardest part of the install.

Does the design use all (or practically all) of the available space? How much for a box?

Yes mine does, all of it. The center console is ON the box snug, If I can I'm going to make it have a few mm between the console and the box. I don't like that it's that snug.

 

I am interested in this box. PM me if either of you are going to make a few. Thanks.

 

If there is that much interested here is what I'll do.

 

I'll use the extra material I have to refine my fitment make sure it's reasonable, and post new pics. Basically I want the center console to fit perfectly for you, I had to work at it to get everything back together just right. Then I'll put a few out and see what everyone thinks. If there is more interest I can take more orders.

 

Just to be upfront with everyone I'm traveling for work on Sunday and will be gone a week, so the earliest I'll be able to get started building these would be 3/10. Maybe sooner but realistically it would be that weekend. I'll get the second version made this week if there is interested which it seems like there is.

 

Once I've refined the design I'd sell them for $200, seems to be the going rate for an empty custom stealth box these days. I have no idea what shipping would be because I haven't weighed the box yet and I'd need your ZIP to calculate it.

 

If you are interested in me building you one of these send me a PM with your ZIP.

 

I'll need 5 people to be serious about it though, which it seems like there is already so just PM me and we'll work the deals. We can do Square Cash, Venmo, or PayPal. 50% down to cover materials and the balance before shipping. I prefer square cash but if you're more comfortable with Paypal that's fine.

 

The only other stipulations would be speaker type and that I can only guarantee it to fit the 2014 Sierra 1500 Crew Cab with bucket seats and the Bose subwoofer. If you don't have that truck buy at your own risk. I imagine any 2014-2017 with bucket seats and the center console will have the space but I can't make any guarantees around that.

 

One additional note is that I did have to trim the bottom part of the dash, it looks like there were mounting points for plastic panels in the trucks that didn't have the center console. I couldn't tell from andreej's pictures but it looked like he did the same thing. If you look at my pics you can see the part that I trimmed just above the box. It serves no function in my truck and won't affect the structural integrity of the truck, or your ability to revert to the stock sub.

 

Only fits:

  • 2014 Sierra 1500 Crew Cab with bucket seats and the Bose subwoofer
  • JL Audio 8W3v3-4 8" Subwoofer

Includes

  • Custom Box, glued and screwed.
  • Gold plated speaker terminal
  • Black Rubberized coating. (carpet won't fit)

 

I may update the design with brackets if the fitment requires it after I rebuild it.

 

 

P.S.

andreej, if you want first dibs on the sales, just say so, I don't want to step on your toes since you did this first. I just used your idea and guessed at the measurements. I don't know how to mention users without quoting so hopefully you see this.

 

 

I'll make a separate post with the people who have asked so far because I think there were already five. First come first serve an all.

Well thank you for taking the time and effort to take pics... second.... how much for a box shipped to California...

 

I too would want a box made and shipped to California!

That's 2 buddy, better setup shop! :)

 

Pm me a price shipped for one. I might get rid of my under seat box.

It looks like these are the interested parties so far. If there are more I'm down to build more. Just see my post above and PM me to confirm interest.

I haven't pulled my console yet. But as tight as it sounds would a layer of sound deadening on the inside of the console with 3-4 layers of fiberglass be an easier fix? As I said, have yet to remove the console.

Help with what?

 

I would like to get some sound deadening inside the center console, but there just isn't the room with the box I have now. (maximized internal air space).

 

I'm not sure what the fiberglass would do, unless you were considering molding an enclosure out of that directing to the center console, which would be pretty badass but I'd be concerned about additional vibration in the center console.

 

I think having some air space (1/8 - 1/16 inch) and sound deadening between the box and the sub would eliminate any rattles and possibly improve sound quality.

Have any general measurements of the box size? I'm thinking of sticking an underseat unit under mine and getting rid of the box behind the passenger seat but I don't feel like yanking my console out to measure, lol!

Yes, I was thinking a molded fiberglass box with a layer or two of dampening material to help isolate it from the console. New born at home so not much free time. Maybe this weekend I'll pull the console and see what I think. I have quite a bit of experience with fiberglass boxes.

That would be cool. If you have the skills you could elliminate the side pockets on the console (which I never use anyway), and get some additional internal volume. Dress it up eith some vinyl on the side, even port the enclosure if thats your thing...

Or go all out and make your own console, not my console but a shop near me that posted on their webpage. I still think the OP's box is the best idea to keep the stock look.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Does your dealer charge you for the tire rotation on top of the oil change price ?. I haven't had any service work done at my dealer yet other than when I brought it back soon after owning it to have the front end aligned to correct the steering wheel being off center a bit. Oh they called me at least twice hounding me to bring it in for an oil change and pushing a 300.00 package of oil change and tire rotation and whatever other quick simplistic checks they would do. Only going off of what a friend gets charged for his half ton for the basic oil change and its the same amount of oil as the L8T holds, it was about 150.00. Once one buys a set of tires from most shops these days or so I believe, they will do free tire rotations and some do free tire balancing as well as free tire repairs.    Certainly doing a tire rotation is no five minute job, and definitely not at home but because I run a set of winter tires on their own wheels, I swap them at home and its a one tire at a time deal because of the tire season swap although I jack up the rear and do it and drop it back down and then raise the front and do them and coordinate the tire rotation into that process for both sets of tires. I am using a floor jack though and if I need to raise both ends at once I use a couple sets of jack stands to have all four tires off the ground. I use either an air impact or battery impact and have electric impact as well so no shortage there of easy methods to spin the lug nuts, and then retorquing the lug nuts. None of it goes quick though but my wages are cheap though ... zero. I live an hour out of town, its easier just to do things like that myself than waste a bunch of time in town and having to make an appointment and probably a special trip and sit there at the tire shop waiting for them to get my vehicle in and get it done and not screw something up in the process.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.

      Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like

      Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.

      GM discontinuing interior parts on a 5YO vehicle??

      By Z45 · Posted

      Very often the part number on the trim part is just for the vendor order/assembly plant and will not show up in the parts system.  They won't make a bunch of extra parts that were not ordered. Keep in mind, lots of these parts were made to be "just in time" parts meaning they were dedicated to a vehicles ordered and sequenced for assembly.       Also, trim parts will often say, paint to match.
