I know there are some double cab owners interested in sub boxes for their trucks. I didn't like the pre-built Silverado boxes I've found online, though I did like the look of the JL Audio stealthbox but couldn't see spending a grand for and enclosure with two 10's.

 

Here's the one I built over the weekend for my truck78ff048d79fa13af66f1e4e1dbde520a.jpg. It's constructed from MDF for the top and sides and fibreglass for the floor/sides. it's approximately .65 cubic ft. per side.

 

I have two JL Audio 10W1v3's in it and its powered by the sub channel of a JL Audio RD900/5 5 channel amp.

That is a good looking box. Is it a sealed enclosure? I look forward to getting a little time to build me one. Seeing this one gives me hope for my system. I have an amp wiring kit on order. Hopefully I am right behind you.

Great work! I love JL audio equipment. My first silverado was an extended cab that I turned the rear bench into buckets, and built a painted enclosure in between with two JL audio 12w6v2 subs, and JL door speakers, in bed amp rack with a TV, headrest tv's, and in dash DVD. Then I got married, had kids, and that hobby ended lol.

10's facing up don't get absorbed by firing into the seat? I have the factory underseat storage bin, am considering taking one side and converting it to a sub enclosure. SImiliar idea, I would make a baffle to mount the sub cut out to fit the shape of the bin then fiberglass reinforce the bin. Way the bin is molded, down firing would be difficult to accomplish without completely cutting out the bottom. Facing up makes it a lot easier to install.

Thank you, and I know all about getting married and selling off the toys. In my case it was a 70 ss big block Chevelle.

I didn't even make it to my wedding. I sold my 95 corvette when my first daughter was born.

I am inspired to go the same route. Mdf top and sides and fiberglass bottom. I don't really know how to calculate the size I need so I am going as big as will fit then maybe fill with shipping peanuts to get an idea of the air space inside.

 

What did you do OP to figure your air space? Some calculations then a guess?

I went with one 12"tw3-d4. The box is unfinished , of course, but it hits hard at this point. I worked on this box a couple hours a day for 4 days. Spent a lot of the time deciding which shallow sub to go with or if I could fit a full sized 12". I had to have a 12 and it has to be as small as possible in the floor board. I want it to be finished with an exterior gloss black so it's off to my body shop buddy for that.

 

Thanks to the OP for the post. I wasn't really thinking about a fiberglass box when I started this build.

Your sub so hitting the bottom of the seat. Which in time will start wearing a hole on the surrounding and you'll get an annoying sound that sounds like a or leaking. If you are able to lift the seat I suggest put doing it. It's also checking out the sub not allowing it to travel freely

I located it under the seat so that I can add the 12"grill from jl. Going to get it today. It is tight under there but with the speaker grill I think it has a chance. It's a trade off, but I wanted a 12" at all cost and I didn't want it taking up to much of the back seat floor space too.

Grill should be fine then. Thought you were going to leave it like that

Well the grill does and doesn't work. It works and protects the sub but when I sit in the back seat I can feel the grill buckle inward then pop back out when I get up.

I didn't realize how much of the 12" JL TW3 sub was above the mounting line. It is more than other shallows. Because of this it is very tight so I am going to use my router and cut out 1/4" for the sub and see if that will work.

This isn't an issue with no one in the back or with my little girls but if I or another grown up sits back there it might bend the grill. I am still trying to perfect this issue. Other than that my custom box with sub hits, HARD!!!

 

The box is unfinished, I will be painting it black.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      By Core-Lokt · Posted

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
