2015 Silverado Dash speaker wiring

Good morning all,

I have a 2015 silverado crew cab with 8" mylink. Non-bose.

 

I have the 2 Metra harnesses on the way to create a T-harness behind the head unit so I don't have to cut factory wiring.

 

I'm wanting to install my focal components with an amp and crossovers. Ideally I'm wanting to use the factory door speaker wire. I've read that there is a harness in each kick panel that splits the wire from the head unit out to the door and the dash speakers.

 

Would I just be OK to run new wire from the cross overs to the new tweeters in the dash? Disconnecting the factory dash speakers and removing them. Then use the factory door wire for the replacement door speakers?

 

Or do I need to cut / disconnect something in the kick panels? I didn't know if there was a factory crossover somewhere in the kick panel / dash for the factory dash speakers.

 

Does anyone have any pictures with the kick panels off and the split between the door and dash speakers?

Where the front splits, don't know, it may be in the kick panels, but certainly removing them should give easy access to feeding new wires up to the dash.

This is how I plan on bypassing the front wiring. Run a nine wire from and to the metra connectors. I'll be pulling the front wires before the go back to the fa Tory harness which will bypass the kickpanel wiring. Then I can run the wires from the nine wire to a crossover and to the doors and dash.

That's basically my plan as well. I'll be running 9-wire to a JL Audio Cleansweep. Then over to an amp and the crossovers. 9-wire from the crossovers back up into the dash area. I'm hoping to use the factory door wire for the woofer and run a new wire from the crossovers to the new tweeters. I'm just hoping when I unplug the factory dash speaker there isn't anything else inline with the door speaker wire, as I know they are tied together somewhere.

I was just reading on that clean sweep. I get the premise of its job but curious if it is needed in the truck. I know you can turn off the volume adjustment so you have to turn the volume up or down and not let the truck have control. Also the small 3 band eq has much to be desired. I'd really be interested to hear how this thing works. Will u be wiring this in from the get go or after an amp and speakers to see if it made a difference?

I'll be using it from the get go, I already had it from my old Impala. I'm not sure how bad the stock signal is, but I like being able to start with a flat EQ, as factory head units tend to be tuned for the stock speakers even if you set the EQ to flat on the touchscreen. I won't be using the JL volume control, I'll be using the truck volume control. I just watched this video last night as a refresher because it's been 6 years since I had the cleansweep in use. Excellent video (but a tad long)

OK...you suck. Lol. Just watched it and see its not all about auto volume control. Maybe this is the reason the rear doors sound low and flat from the get go. I wonder if when you add this you will have a problem like the Lincoln premium stereo. That would suck. I'm assuming if you have the Bose you'll have that problem but the non Bose should just need the clean sweep. Also found it nice you are still able to utilize the low mid and high adjustments for eq as limited as they are. When you did your impala, was the sound quality and difference audible? Sucks now cause I'm interested in this and the wife will tell me to find a cliff real quick lol. I was looking on their site but seems this is an old product. What would be today's equivalent to this from jl or any other brand?

Lol, it will take me probably a few months to get everything installed. Life is busy busy right now. Once it's in I'll listen to it with it enabled and disabled, but I imagine you will already be done by then. I'm guessing that:

http://www.jlaudio.com/fix-82-car-audio-oem-integration-98100is there replacement for the Cleansweep, but ouch on the price! I'm not sure of any other brands as I haven't looked around since I already had this one. On the Impala it sounded pretty good. Eventually I replaced the entire Head Unit with DVD playback and screens in the head rest etc... but that was an '06 impala that didn't have all the fancy touch panels and stuff stock. My Silverado is non-bose. I've read that it's full range out of the head unit to all 4 doors and dash. I don't have a separate sub, so I don't believe I'll need the signal sum unit from that video.

Also, has anyone hooked up a 2015 - Non-bose to an RTA with the EQ set flat? I don't have an RTA or I would. I'd be interested to see the stock curve.

Yea this would be a very last addition. Is this essentially a DSP. I see crutchfield has the lc6i. Not sure if this is in the same boat or not. Once I get the front door and dash replaced I'll see how it sounds. Just took a ride and it really is missing the highs even w the eq cult tilt on the highband

Hey guys. Did anyone figure out what the wiring is to the dash speakers? I disconnected my front stock speakers, and the dash speakers stopped working. I'm wondering if there is some kind of loop that I broke, or if I somehow blew the dash speakers. Any help would be appreciated.

Don't think the front speakers are wired in series, I tried running just the doors (without dash speakers), worked fine. Both dash and doors are fed from one output off the head unit.

Grn, do u know what ohms the front are. Not sure if I asked before. Assuming if wired parallel maybe 8 ohms to get a 4 ohm total. I measured the rear speakers and they are 4 ohms. Unless they are 4 ohms in parallel and have some sort of resistor in line to bring them back to 4 ohm

Got it. Thanks. I think I might have just blown the speaker. I'll check it out!

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
