It was very noticeable in both my lmls. The idle rpm is up around 1100rpm which increases the idle speed by 2-3km/h. If you were towing or loaded it wouldn’t be noticeable.

You can do more mileage per oil change on the diesel so it’s a wash. On the 6.6 the rpms are higher while idling during a regen. You notice when you come to a stop the truck feels like it’s trying to pull through the brakes and the truck moves much quicker at idle speed.

The 6.6L takes 10qts, maybe that’s where he pulled the number from?

Get the Lc2i or a dsp (is go dsp personally). When I added my sub the shop used a basic LOC and it was just “meh”. Not what I expected from a JL 12TW3. I added a gain controller knob to the amp and again it was only a slight improvement. Added a Dayton audio dsp for $200 and it brought the sub to life! Your limited to what the oem stereo puts out as far as signal voltage without some way of turning up the voltage to the amp it. The dsp fixes that and allows you to tune the sub and expand later if you choose to do so.

I hear a noticeable difference with my JL 6x9’s and infinity dash speakers using the rest of the oem system. Less distortion but the timing is off so I just set the balance a bit heavier on the right side to even it out. Wife doesn’t complain so it’s all good. Adding a sub is a must IMO before anything else. The stock Bose one is ok for a stock stereo but sucks if you’ve ever heard a half way decent setup.

Really? Funny because my fronts are 6x9’s

I have a fix 86 but may not end up using it. I picked up a Helix dsp3 and hope it can clean up the incoming signals. If not I’ll go navtv for simplicity. If you’re using a basic LOC for a sub I would highly suggest getting a dsp. You’re missing out on 50% of your bass without it even using a bass knob to try and boost the signal.

Yes iPhone X and no eq. It could be because you have the volume maxed on your phone? With the USB cable anything much passed 1/2-2/3 volume is really loud.

I found the opposite and the sound quality is definitely worse with BT compared to USB.

I didn’t say it doesn’t work, it’s just distracting when I’m trying to make an evasive manoeuvre and I don’t find it to be of any help. If I made a habit of not paying attention then I’d leave it on. I had the seat and the lights off after the first time it did it’s whole thing. My new truck doesn’t have it so it’s a non issue.

Not close at all. It would mostly happen when I’d be avoiding the a hole that cut me off to turn into the parking lot or the street they were about to miss. I’d be changing into the left lane to avoid them and my dashboard would look like a Christmas tree and my ass felt like my wife’s lightsaber was stuck in the seat. Just leave the driving up to me thank you very much.

I’d like to have the HU display and the surround cameras but everything else would be turned off before I left the parking lot so I didn’t order the package. I turned off all that Collision avoidance and lane departure crap in my denali on the trip home as it was nothing but a distraction. Sunroof, yes. I work in the dark and I like having it open with the split back window during warm summer nights.

I have a 19 with the Bose system. You can just swap the speakers but get the connectors from crutchfield or you’ll end up having to cut the factory one off the oem speaker wires. The timing ends up a bit of a mess and the infinity coax’s that I used are way to bright causing me to have the treble turned almost all the way down but it’s manageable and a heck of a lot better. Start with the 6x9’s though as I mentioned, you may not need to change the dash speakers.

3.5’s won’t fit. I had to cut a lot out and they still didn’t fit perfect. Get some 2.5 full range for the dash and better 6x9’s in the door. The 6x9’s made the biggest difference for me. I have the oem Bose stereo, it’s ok for stock but once you upgrade it you see what you’re missing. I’ll be using Morel CCWR 254’s in the new truck but it’ll be a 3 way active setup. After I replaced the speakers the timing was way off so the sound comes from the right corner when you have the L/R balanced and needs to be faded to the right to balance it for the drivers seat. I would recommend starting with a 6x9 that isn’t coax and go from there.

Get a harness made up from [email protected] I got mine in a timely manner and it’s nicely built. I’m not sure how it works with the non-Bose but he can answer your questions.
