Has anyone specifically upgraded just the sub in the factory enclosure? Do not want to lose any of my under seat storage. I have a few 6.5 subs that I have been very impressed with in the past and think with more power and a better sub it could be a great setup.

I tapped the existing Bose sub's wiring to provide a signal for an aftermarket amp.

But I did not replace or even touch the factory Bose amp. All the original Bose equipment was left in place and functions normally.

I simply added an additional Fosgate amp & Fosgate 10" sub to give the system more low end.

how did you determine which wires were for your sub? I have a 2016 silverado with bose and on my bose amp under the backseat the wires are a different color than yours in the location you tied into. Maybe mine is different because i have a version without a sub? im not sure if i have a sub or not

Do you have a factory amp bolted to the rear of the cab? Curious if the bench seat Bose gets an amp without sub.

how do you determine if you have a sub or not with your bose system? i have a 2016 silverado with bose, ive found the amp but have no clue where a sub would be located

It is under the center console if your truck has one. If you have a jump seat you have the 6 speaker Bose with no subwoofer.

Added a RF P3S-1x10 P3 sub with a RF PBR300x1 amp in a regular cab truck. Sub sits right behind the seats and the amp sits right next to the sub. Tapped the B pillar speakers for the speaker level inputs on the amp. Sounds great, and relatively inexpensive at 300 bucks for the whole deal. If anyone has questions feel free to DM me!

Did you run the amp to any other speakers, or just the sub? I have a 14 rcsb and no one makes a kit that they say fits. I contacted Kicker already... I installed kicker 40CS6934 6x9 3-way, and still have the 40CS44 4'' 2-way speakers to install. I ask because with my factory radio I cannot hear out of the rear speakers and wasnt sure where to tap in. I thought about tapping in with a LOC behind the radio and running RCA to the rear... can you still fold up the center consul?

Does anyone know the wires for the bose front door speakers without a console, I am guessing those are the best ones to tap into for adding a Sub.

so i dont have a factory sub for my bose. i ended up tapping into my front door speakers for my line out converter. everything works except for my front door speakers lol. sub hits hard but those front door speakers sound super muffled. i also tried messing with the settings on my amp and nothing fixed it.

I wonder if anyone has put an RTA on the stock signals. I can only imagine that the Bose system has some form of DSP going on. I am imagining the the sub signal most are taping is limited, more than likely a subsonic filter and probably a pretty low xover point so tapping that would probably limit the upper bass fz in the aftermarket subs. I saw a post in this thread where someone mentioned the rear signals were not all that clean. Taping the front would pick up the chime and any voices that come through the system. I don't care how high pitched the chime and clicker may be some of that will transmit to the sub channel. I'm just trying to figure out which channels to tap for the cleanest signal without getting into signal summing. I'm thinking for a sub the rear L+R would be the best using an Lc2i.

There is a Silverado build on a mobile audio forum where they did an RTA and they recommended using the rear speakers for the SUB LOC. It had the exact RTA as the Bose Subwoofer in the console.

I pulled 4ga through the grommet on drivers side it wasn't easy by any means. I unscrewed the relay box from the inside of the cab which roped a bit that and lots of lube!!!

 

If anyone is looking for a great sub I just bought a JL Audio 10 TW3 2 ohm wedge box. It fit under the seat tucks back in and you can't even see it's there. It's a great sounding sub. JL has rewritten the book on shallow mount subs. I have it on a little 5 Chanel alpine amp that 60x4 and 350 rms to the sub. No need for a custom box I could fit 3 of these subs under my rear seat, but 1 is enough to shake everything in my truck to the point you can't see out the rear view mirror. Very happy.

 

While I'm talking up JL I'm loving my 6.5 C5 components there so smooth. I chose them over focal poly glass and I'm enjoying them!

 

IS that in a double cab or crew? Thinking about doing the same thing in my double

Does anyone know the wire colors for the rear speakers, Bose w/sub? Also can the rear speakers wires be tapped at the Bose amp?

If you have the RPO UQA, this is the wire diagram, BOSE w/sub. I'm in the process of adding a sub to my 2017 Silverado DC, and I'm going to tap into the Sub -/+, and will try it with/without an LOC(LC2i).

Bumping this thread. Anyone build a full length sub box for a single woofer? All the premade ones are only around .7cf and I'd like one for around 1.3cf.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
