AudiOn19s

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

MAFD2 - assuming you are running passive crossovers on the CDT? What frequency are they crossed at?

You have my attention, I’ve only ever seen a tweeter in the stock location when others have run them in a 3-way configuration. do you feel like you lost upper mids in the 400-1500hz range with those?

All, I have a '21 Sierra with factory Bose. I've added an amp and a pair of 8" subs with a processor which has allowed me to fill out the bottom of the sound stage quite nicely. In doing so I was able to turn down the bass on the rest of the system which actually helped sound quality quite a bit in my opinion. I've done full stereo builds over the years and I'm trying to avoid that here. The current setup is ALMOST where I need it to be to be happy with it but where it's still missing is a bit of clarity and detail up top. I don't need it to be louder, I'm just looking for clarity. I know that ultimately that comes from enough power to drive really good drivers but again trying to find a happy medium here. I believe the dash speakers are the key to rounding out the sound profile I'm after. I'm considering the following: Pioneer TS-A709 - only proper 2 way with dedicated tweeter AudioFrog GS25 Kenwood KFC-X2C I'm curious if anyone has been able to demo these back to back to compare? I see reviews of each of these individually on this board but given there's nowhere I've found to go try to demo them in person I'm curious if anyone here has been able to do the same. I'm honestly leaning towards the GS25's but I worry the factory bose amp won't be able to do them justice...that said they get pretty stellar reviews in the GM truck forums where people have used them. The Pioneer seems like the slam dunk of the bunch but I haven't been the biggest fan of them in the past and worry it's not really going to provide the detail I'm after...just a tweeter to get really high frequencies that will ultimately be fatiguing instead of adding value. I guess I could order all of them and take advantage of return modern return policies but would prefer to avoid that if someone else already has feedback on one vs. the other. Thank you,

Yes, ohio

Bringing this back up for a follow up question. Will the truck go into ad-hoc regen on very long downhill runs like through the mountains? I smelled a little bit of smell on the first regen that smells somewhat alarming...almost like electrical components overheating much less than exhuast or brakes or something like that. I dismissed it as regen. BUT....on a recent 2500 mile round trip I could tell when the truck was in regen on flat ground and never smelled anything in the cabin like i did on the first regen, however when the truck would go downhill for extended periods of time the smell (again best described as electrical fire) was VERY pronounced. and would go away immediately following the decent, almost as if it wasn't really in regen at all. thoughts? **edit** downhill runs were not in tow mode so it wasn't jake brake, and my application of brakes was sparing at best, they were not hot esp with air temps in the 20's and 30's.

Bringing this back up to make sure I understand correctly. you're pulling anything below 150hz or 300hz out of the front 6x9's to clean up the front stage mids and highs but the rear door 6.5's and the center Bose sub are still operating down below that level to adequately supply mid bass frequencies to the total stound stage correct? I bought these to install when I do a t-harness and aftermarket amp / sub install in the back but I don't intend on running my sub above maybe 60hz and want to make sure there's not a hole left in the soundstage after I install them. Thanks,

Would you guys mind showing where you mounted your bass knobs and how you best routed the wires to get it there? on my 08 I had it in the center console open area right in front of the cup holders but I had the whole interior apart already and it wasn’t much effort to run. I’m thinking since I will have the passenger side panels pulled to run power wire I may run the cable for the bass knob back up that path and just try to find a spot under the dash for it. Would love to see what others have come up with.

appreciate the feedback here. Thanks for the input.

I need some input on a new truck purchase. Currently I have a 2007 Sierra SLT with a 6.0L (LY6) and 4l60. I've towed for years with this thing towing race cars on open trailers and it tows perfectly fine at 80 mph without a ton of drama. This year I started towing a smaller, enclosed trailer but the trailer has 7' 6" interior height with an air conditioner on top of it and it's an absolute parachute behind the truck. The truck tows perfectly fine at 70-ish mph but when you get to 75-80 mph it wants to constantly run in 3rd gear and when it's in top gear it is nearly impossible for it to get into converter lock. The thing has 250k miles on it and this is pretty much the last straw for it so I'm searching for new trucks. Trailer weight fully loaded is only 2200 or so lbs so it's not heavy, it's just horribly inefficient from an aero standpoint. Will the modern 8 and or 10 speeds resolve my issues and just lock in in a gear that won't be 3500rpm +? I tend to think the 5.3 with the 8 speed or 10 speed would have enough variables in the gearing to overcome the aero drag issue I'm dealing with, but I wouldn't be opposed to the 6.2 if it's absolutely necessary. So back to the original question. Give me your towing experiences at 80mph with the new trucks. This is pretty much #1 factor in what truck I'll decide to go with.
