Does anyone know if the front door speakers (6x9) on the Bose system is full range or not?   I've seen many people upgrading their front door speakers with components or coaxial speakers, so I just bought  a pair of component 6x9 and thinking of mounting the tweeter at the top of the door panel.   I want to see if this will be a plug and play swap, or if I have do to more.

 

If they are not full range, then maybe I can share the signal from the dash speakers for the tweeters?

 

Thanks in advance.

Yup - the front speaker is a full range signal with some slight bass roll off at really high volumes.  If you replace the dash corner speaker with a tweeter, I would recommend an inline crossover or capacitor.  The dash corners are fed with frequencies too low for a tweeter.  If you replace the dash corner with a wideband (like Audiofrog's GS25, it is plug and play and handles 200hz all the way to 20,000hz, safely.

Holy crap! $270 for those GS25 speakers! The dedicated tweeters from them are $400! They better sound amazing for those prices!

I'm sorry, I have to disagree. I just setup my audiocontrol D6. 1200 amp and using the input RTA in the DSP software shows that the door speakers are not full range. I had to "sum" the front door and dash bose signal in order to get a full input signal to work with in my amp. 

 

Currently I'm running the stock door and dash speakers with my 12" subthump box under the rear seat. Next weekend I should be able to treat the doors and get those speakers installed. I'm going with Hertz mid bass in the doors and tweets in the factory dash location. Coaxs in the rear doors.

Also, I have to say the stereo doesn't sound nearly as bad now that the Audiocontrol is running the show. I flattened out the bose peaks with the auto tune feature of the dsp, it's now much more bearable. Can't wait to get these new speakers installed.

Any updates? I have a Crutchfield cart full of Hertz speakers/subs and an Audiocontrol lc5.1300. I don't have Bose, so the truck sounds like hot garbage now.

I just finished my install tonight. Audio control D6 1200, Hertz mpk 6 1/2 components, Hertz Cento 6 1/2 for rear fill, Image Dynamics idq 12 for a sub in a sealed box from subthump. I'm using the D6 to run the mpk tweeters active, mpk components in the front doors and channel 5&6 bridged going to thq idq12. The Cento rear doors are running off a small Infinity amp. 

 

As far as an update for you I can tell you that the front door signal is not full range in the Bose system. With the D6 I'm able to sum the Tweeter and the door signals from the Bose amp and make a full range signal from them combined. It does seem that L series amp has channel summing so you'll just have to set that up and you'll be set. I do believe you might want some sort of DSP down the road since the factory head unit signal is not flat.

Agree just put some JL Component 6x9's in the door, to complement the component 6.5" in the rears and the tweeters DO NOT work, so the signal is not full range.   While the upgrade in the rear was a huge difference because you can now actually hear sound from the rear, the upgrade in the fronts are not as effective w/o the full range.   

 

The bass is definitely tighter and cleaner than the muddy sound of the Bose at high levels, but now when I turn it up the dash speakers start to want to max out.   So Ill be replacing those soon too.   As for the tweeters I mounted in the door, I will just leave them for now, until I spend more time getting a full range signal to the doors.

 

My next upgrade is the kicker factory upgrade kit which I purchased a few weeks ago...no doubt that will give it just enough punch for it to sound fantastic.

Can I ask why you are running your sub on 5/6 rather than your doors on the D6, and then your sub on a mono. Was it just a case of what you had around or was there a specific reason? I'm assuming the D6 1200 allows the Line output to be configured as a sub output or am I incorrect in that assumption? 

 

I'm looking at going with an audio control dsp (maybe dsp/amp) and was gonna run some focal components up front and some 6.5 in the back without any subs, hoping I can get a decently clear signal in that truck. 

 

The autobass feature of the AC DSPs is really what this truck needs, it just gets so damn harsh if the volume is anywhere above 1/3.

I ran the sub off channel 5&6 because I thought it was ample power for the sub and I didn't want to waste the quality AC channels on a set of rear fill speakers. I was wrong, the AC bridged channels were decent but lacking a bit of power for my sub considering the active stage in front. So I pulled the Infiniti amp and replaced it with a pioneer mono block 800 watt amp. Now my sub has plenty of power and the rear fill resides on the AC channels 5&6. Also ended up buying AF tweets and replaced the Hertz tweets on the dash. They were just a bit bright and didn't care for them, the AF's are damn impressive. 

 

The AC DSP amps are good but the software is buggy and the tuning aspect of the software is not very friendly. If I was starting over I probably would've went a different route but it was too late in the game to change. 

 

As for accubass, it works but with a remote bass knob you'll find that it's not needed. I set my amp to turn on the bass level to a reasonable level, actually a bit low. Then when I get in my truck and drive if Im not in a jamming mode I don't find myself having to mess with the knob. If I want to rock some tunes, then I dial it in on each song. Works well. So I've switched accubass off. 

 

As for a good signal, you'll be fine. The stock head unit isn't too bad. Basically I don't exceed 3/4 volume and everything sounds clean. I could see some clipping after 3/4.

Oh and spend the money on treating the doors. The mid bass in my truck is amazing with the sound skins treatment and roadkill surrounds. It's probably the most impressive thing about the truck, but the AF tweets are damn good too.

Audio Frog a bit out of my budget tbh. I was thinking either 6.5/6x9/8 Focal or Infinity components in the front with the tweeter in the stock dash location, and some 6.5 coaxs in the rear doors. Looking at a few different Focal sets. I was leaning toward the 8" or 6x9 for the front for a little more thump, hopefully no needing a sub as I really need the space under the rear seat for tool storage I don't trust putting in the bed/toolbox. If I do, I would only be adding a mini powered solution under the drivers seat anyway, so I'm trying to avoid that. 

 

I'm leaning toward LLJs S.I.K. GX500 kit as it seems to be a good setup for quick SQ upgrade without requiring RTA or getting too out of control with my budget... $620+ for power cabling and wire harness with the 4channel mini amp, then about $400 in auditor series speakers from focal.

I was told that the front door speakers in a refresh Bose Silverado cut off at 5k. Also: sub is 35-70hz, Doors: 40hz to 5k, rears: 200hz to 15k.  It's very strange.

Here are the RTA results from my '23 with Bose where I checked the output signal going to the speakers.  EQ was set to flat on the radio and pink noise was used.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
