2021 Sierra elevation crew cab BOSE question

 

I added a T-harness, sub amp and sub to my truck when I first got it to enhance the listening experience. I'm ready to go further with the front stage. This is not an unlimited budget build, but I'd like to do a proper helix DSP as part of this mix and have already purchased AudioFrog GS690's and GS25...the GS25's are actually already in the truck on the stock bose amp for now and while they made a small improvement, like most said here it wasn't drastic. I'm on the fence of adding a tweeter and doing full active 3-way front stage vs. 2

 

My question is in regards to the rear door speakers.   I've read stuff online where people built the whole front sound stage up and tuned it with the DSP and left whatever rear door speaker they chose running off the stock Bose amp.  Does that really work out?  If you're setting phase and timing and the whole 9 yards on the full front stage but not the rear does it negatively effect the listening experience?  I know it's mainly rear fill only but should it still also be processed by the DSP?   I ask because 4-6 channels of DSP and amplification is significantly cheaper than 8 so if I can get away with running full 3-ways up front and leave all the rear door stuff on the OEM Bose for fill then great.  If it's necessary for it to also be on the DSP and amplified for the best result then I need to re-think my plans.

 

Anyhow, looking to hear from those who have gone through a similar decision set and what your opinion is on factory Bose rear fill vs. DSP and amplified rear fill.  Either way not going to put an exotic speaker back there probably Morel 6.5 coax or AudioFrog entry level G62.

 

Thanks in advance.,

Andy

I went full active with an 8 (7 used) channel DSP. Either DSP the rear channels or disconnect them.

 

I have kids who regularly ride in the back, so getting some semblance of quality sound back there for them was pretty high up on my priority list. If I wasn't concerned about passengers, I'd be comfortable disconnecting the rears and just running the fronts to save some money. Leaving the rear speakers in place and unprocessed isn't a great option, as the OEM system needed some serious EQ to remove the BOSE flavor so that there wasn't a weird mid-heavy presence with the Pioneer TS-D65F's I put in. Adjusting the timing wasn't as critical with kids, but the stock setup wasn't set up for a driver-centric image to begin with.

Don't overlook audisons new forza line. Really good amps that can be bridged. I'm digging my GB10, GB25 and Gs690 setup. I have GS60s but their just filling space currently.

 

More than a few suggest dumping the rear and going 3 way upfront. Using the rears correctly, takes alot more effort for a very little return. Esp in our trucks as the cabin isn't that big.

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
