Well I got a good bit done today. No sound yet that will come tomorrow. I will fix the photos later doing this on my phone.

You think that is enough clearance for the sub? That looks like the RF p3 shallow sub which I owned in a 10". I cracked the cone on mine because of that very reason.

 

I guess I am looking at a regular cab there. That is exactly how I cracked mine in my old Tacoma single cab. Don't underestimate the excursion of that sub.

 

I guess I don't know how to quote with pictures.

I think putting up your build and some pix would help someone that might be just looking for ideas. It never hurts to share   Great job by the way, if you're happy with your work, then it's all goo

Don't feel either of these locations have sufficient space for a good musical sounding enclosure. Under rear seat will have enough space for a properly sized and tuned enclosure.

I think you are right. It's good for sure when the seats are down but in the up position it's close. I'm going to see if I can shift the seats forward some may be able to get half a inch. Since this first box is a test run to see if the .37 cu ft works for this set up I can always trim the box down another half a inch where the sub is and increase the depth outside of the sub. For now the plan is to turn it down when the seats are up.

That is one thing I like about my jl shallow over the fosgate shallow. No vent hole on the magnet. It can be mounted right up against the mdf. I put some dynamat there first but still.

Ok so here is the latest update. Got everything up and running today. It sound good adds good deep bass and really helps the sound quality. I'm thinking it could be better with some fill in the box and I may try a JL sub at some point. Also found out I have a leak behind the drivers seat. Carpet was soaked. I will add some pictures in a little.

I was very happy with my RF p3 in my Toyota. Even after I cracked it I taped it with aluminum tape real well and it hit just as hard.

I was very close to going with the Mtx shallow sub then the kenwood shallow as I was trying to keep the cost down. Then I decided that I would look at the JL and I somehow convinced myself to spend the money for it.

I love it and it hits but I have decided that I am going to build a full length under rear seat ported enclosure for it. It sounds great but my sealed box has its limits. I think it has maybe .6-.8 cu ft. I am thinking if I give that JL a cubic ft or more in a ported enclosure than it will take it to that next level.

I have a wife and 3 daughters so I was lucky to find the time to build my mdf/fiberglass enclosure. Hopefully I will get it built in the next few days. If so I will post a little write up with some pics.

I look forward to seeing that. I just went out and changed the phase on it because something just didn't sound right. I'm sure glad I did whole different sub now. Amazing what happenes when sine waves cancel each other out.........kinda like what what you get in the 6.2l with bose. I feel you on finding time. I have a expecting wife with out first and a huge dog so for me this project was all about not taking any space from the truck and I think it really worked out well. Btw this box is 32Lx12Hx3D outside dimentions with 1/2inch mdf. So I think with the sub it comes out to .31cu ft.

Going to be doing the sound mat behind the sub and amp tomorrow. Then I can start putting the stock sound dampening back in. Sure is noticeably louder with out it. I also have some poly fill for the sub box but over all I am very happy with the set up. The fact that it used up no space from the normal cab area is the best part for me. Does anyone have any interest on a actual build post on this vs some pictures with not much info?

I'm interested because I have a storage bin under the rear seat of my double cab and have no where to put a sub until I came across this post. I was even considering just putting a bazooka tube, standing up in the middle of the floor of the back seat since I rarely ever have anyone back there let alone 3 people.

Just Curious,

 

Has anybody every tried this system?

 

 

I did look into that before building my own box. Im sure it sounds great it was just somewhat out of my price range for the project.

never mind was able to save the pics and turn them around on the computer. I'm wondering if the rear wall is the same on the double cabs ?

      MPG at 600 miles

      By Chuck FB · Posted

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.

      We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
