I just did this, thanks to your video and article you posted, and I cannot believe what a difference it made. I hadn't even realized that I was even missing out on anything. My door speakers are now all pushing base which makes the experience even better! I'm amazed! Thank you again for the time you take to do these videos. :) It is very much appreciated!
Glad it helped!
This is amazing. I got a Bose amp from an SUV and I want to add it to my 2002 Chevy Astro Van. This has been very helpful in showing there are many ways to add a aftermarket amp and using the stock speaker wirers! Thanks for making this video!
thanks for watching
Thanks man for this video. I just sat down and did mine just gotta go out and install it. Huge thanks
Thanks your video saved me from blowing my after market amp. Now my system thumps like it should.
Thanks for watching!
Just did this to an 01 tahoe non bose. Fixed my no sound issue.
I did this a couple weeks ago in a 2001 Tahoe. Worked like a charm. Thanks
thanks so much for watching!
Don’t u have to bypass the amp just to play any music at all when putting in a new head unit ....???
Had a 2002 Yukon before
Wouldn’t play nothin
Thanks for sharing it, this will be easily for my new subwoofer install and aftermarket stereo
Thanks for the information! Keep up the good work! Ill be watching!
So glad to help!
Quick, concise video. Fantastic! 👍
Tahoesteve, i just did this bypass after watching the video!
Now i need better speakers hahaha
(I listen to metal) very easy. Only took me 20min.
Thank you for also explaining how to still use the back tweeters and factory amp/sub!!
I love everything about my 01 LT, but the sound system definitly wasnt impressive..till now!
Nice work! I've been listening to Hard Rock/Metal/Thrash since the 80's so I understand the need for a good sound system. Thanks for watching.
Thanks so much it worked great awesome step via step my Tahoe sounds amazing with the amps now I see roll off effect is gone I have more control of sound and can crank it thanks Tahoe Steve
Glad it helped
What ive learned with most car manufacturers is that it doesnt matter what features they put in your car the wireing is ussually there to plug into them so taking that into concideration if you find a truck without the bose sound system chances are there is a factory bypass plugged into the cross over plug and you wouldnt have to go threw this but its very interesting in case you cant find one in a junk yard you can still get it done
Thanks man I've been so confused about why my front speakers were so low ive replaced the speakers twice lol really appreciate it
Glad to help!
I never comment on anything but this is EXACTLY what I was looking for!awesome instructional video
Awesome, thank you!
This worked for me thanks alot 💯
Glad I could help
As for those wanting to buy the harness O'Reillys sells the harnesses that will work. The harness is the same. But the pins inside are not. The one I bought didn't have enough pins in it so I bought two (2) harnesses so that I would have enough pins. And it worked beautifully.
thanks man. I did it without buying the clip.
jes1kbs2002 jk
How did you do it man im going crazy with mine
Do your steering wheel controls still work for the aftermarket radio?
Metra also has a 70-2054 kit it is the 24 and 8 pin harness for those that want to bypass both.
When you say both, what do you mean. This video shows amp bypass. What else can I bypass.
They sell a bypass now online pre-made, its marketed for an 01 Monte Carlo but I read that it worked for an 02 Tahoe. Ordered it and will find out soon, it ranges from $8- $15
It worked perfectly, if I could post a photo I would. It was advertised as an amp bypass for an impala/monte Carlo and came prewired, didn't have to do any modifications. It was pretty much plug and play for my 02 Yukon, amp was in the same spot as this video
Metra 70-2021 bypass work the same way and save time thanks in advance keep up the good work and videos
Thanx for your help
And that was the easy one
Thanks for watch
😎👍
Thanks for watching
SO you are using the factory speaker wires? I have a 2001 Tahoe which has the same exact system. All the speakers quit working except the rear 3" pillar speakers. I am wanting to install an aftermarket head unit but I don't want to run all new speaker wires because of this factory amp. SO I can hook the new head unit up with the wiring harnesss from Crutchfield then do the bypass thing you just did with the Metra harness and I should be good?
Great video brother.
many thanks!
Love your videos 😎😎keep it up..
By the way
I'm Tahoe Victor 😂😂
Hey Tahoe Victor. Keep me posted on what you do to your Tahoe.
Is it gonna be the same diagram for the 2000 tahoe no bose. But plug says needs to be a metra 70-2021???
I was looking at your video and I’m trying to see how do you get your feedback from your aunt from bypass in a factory amp
so i have a 08 Trailblazer ss with bose, i installed a W4400NEX pioneer double din. my question is can i reuse the pre-existing speaker wire and cut the clips off the oem amp and just run some speed wire to the location that i want my new amp to be from the speaker wire that was connected to the old bose amp ? i want to have two separate amps one for voice and 1 for subs, thanks.
So if I just cut the harness and find the power and signal and ground and hook it straight up to the head unit I should be good right the power isn't coming from the amp is it? what I mean is the original power doesn't go to the amp first and then it branches off from the amp?
Awesome video and thanks for making it and posting it. So would these two Metra kits be what I need for my 2002 Suburban 1500 LT with standard radio not the Bose?
Hey instead up splicing wires to bypass the factory amp, you can unplug that same 24 pin harness from the amp and plug the aftermarket radio / new harness directly into the same harness you just spliced or bypassed
what do you mean?
Which kit?
From the factory amp in the dashboard. Same 24 pin harness is used on the back of the radio as on the factory amp. Hard to find it in there
Nice job, thank you
Thanks for watching!
Doing this will you still have balance fader and sub lev er l controll on the radio?
Can you explain how the speed wire goes into the stock wires
Why is the amp still plugged in? Would anything change if you unplugged it?
My factory amp makes a white noise.
Sitting down to do this now. I depinned my harness and I don’t see it being possible with the 70-2002. I need a total of 16 pin ends and I only have 12 plus the red mess which is all y’d into eachother. Even if I dissected that I’d only have 15... am I missing something here?
Steve... Thank you for this tutorial! I'm working on it now. Question for you.. Using a sony dsx-gs80 hu and plan on hooking my 8" sub to it. Where are the wires for that sub? On the amplifier? And do you know if I can bridge rear channel on a hu to this sub or do I need to just use channel 3?
I'm not 100% sure how it was originally wired to the sub. I added an aftermarket amp and sub and wired them directly and did the amp bypass.
Thanks for the video, great guide! You can also use the Metra 70-2021 as well if you don't want to DIY the wiring. I'm not 100% sure if it would kill the rear sub/tweeters but I am getting ready to install a new headunit in my 02 suburban and may have to give it a try.
appreciate the comment.
How did the 70-2021 work out with your install. I have a new head to put in and want to bypass the amp...
@@michaelgracephotography8308 Worked good, all the speakers still worked including the sub. I replaced the OEM speakers with Infinity Ref and a pioneer shallow mount sub.
@@draconis112 I've ordered what I need, can't wait.
Thanks for the tip!!! 👍🏻👍🏻👍🏻
EVH 🎸🤙🏻
EVH forever! Anytime
All of my speakers cut off around 30 of I turn it down to around 26 to 28 they come back on would the bypass work for my truck or should I replace the amp 01 tahoe
How do you do it on a bose amp on a 2004 chevy silverado 1500
Thank you very great idea work for me
Thanks so much for watching
Same slots on the 16 pin connectors? How many wires there 16. Red, yellow, black, blue, then all the other speaker + wires only. What’s the pin slots?
Do i need to have an amp working on the door speaker in order for this to work?
When doing this does your factory sub still work
Only one speaker work in my car and that's on the right side. The 2 backspeakers just went out I'm trying to hook up 2 new apps and 412 speakers, and the last 2 back ones went out. Now I'm trying to make sure all my speakers are working on all 4 doors and the extra 2 went back to deep pillars and not the on the internet. That's showing me how to make my 2 back door speaker's work and the D pillar speaker's work.
What if I just install the stereo without this bypass? Would I just no get sound on door speakers? Or would I just no get lows?
I have a 2000 GMC yukon, my rear tweeters just stopped working, could it be the factory Amp be the issue?
I know this is an old post so I may not get a reply, but im about to bypass the factory amp also and had a question. Did you have to use a 4 channel amp to send signals to the amp using the RCA and speed wire? As in RCA's to give the sub sound signal and speed wire for the door speakers? And if so do you have to splice the harness coming off the radio? thanks for the video!
Sure you figured out by now but just in case LOL. If you are installing a sub only and have factory Hu you run a proper and that matches as close in rms not peak to you sub so sub handles 600 rms at 2 ohm then try and find a ame with a rms of 600 watts rms is steady power what it outputs like 1200 watt doesn't matter as much as rms in all speaker installs. Then your run the RCA and Renate wire which is what I assume your referencing as the speed wire. That goes into the back of Hu they make adapter for stuck headuncts called line convert out I think,, basically extra part I0 connect your rea and remote wire non of you already have aftermarket hardest which I wou ld get first for any upgrade you went need the loc it will have RCA and remote wire connect on radio harness already. Same goes for door speakers get a 4 channel run set of RCA and remote wire to headunit and then speaker wire goes from amp to each door speaker. You have a +/- wire going to each and that's how gu run aftermarket speakers and amp. You can also get a five channel amp, which will give you the same concept except you only have to run one set of RCA’s and remote wire(speed wire). There are other configurations and I’m pretty sure you can buy RCA wires to run directly in some head units and amplifiers. I’m sure there’s other tips in anyone will correct me if I’m wrong, but this is just a general explanation. Also, you will have to run your power wire and ground wire for the amp obviously but I didn’t mention that. Hopefully you were able to figure it out either way.
.
Great video! !! Thank you so much! One question, I have tag that the speakers are 2 ohm on these factory systems. Had that been a problem for you? Most head units are 4 ohm
It was not a problem for me, but I can't say for sure, all my stuff was 4 ohm. Hopefully someone else will chime in...
Hey man will these work for my 1999 Tahoe classic truck two of my fronts are working but my back is not please let me know thank you
At least your watching a video of Alex Lifeson, one of the most underrated guitar players in the MOST underrated band.
Is this the same for a 2011 Ltz extended Silverado?
I have a 2001 tahoe would be fine if I just cutt the blue and white wire that plays the factory sub. So it won't distort my own subs?
Good info dose that for 04 Tahoe z71 with Bose system I had tapped in to that to put in my aux plug
i dont think it will work if you have a Bose system. hopefully someone who knows for sure will chime in
Do you know where
The amp is at on a 2002 silverado ext cab?
How do I connect an external switch? How do we connect the Wi-Fi from the radio to the switch?
great video! thanks.. i have an 03 suburban that the OEM head unit (6 changer CD) with bose speakers. the speakers lose output but the head unit remains powered. hitting bumps or something intermittent cause it to go on and off. The ding ding ding door lock functions is also silenced when this happens. ARGH! I have heard it could be a bad ground in the A column but now that you have shown me there is a separate amp i am thinking it is related to that because like i said the sound out put is affected but the head unit remains on all the time. Any ideas or insight? thanks so much!
I also have a problem like that bro I hit a bump once and now it starts playing for like 2 minutes and then I lose power
Yeah even though I only hooked up power in the ground signal still plugged it into the factory harness there's no way around that so it is still running through the factory amp I just can't get it right I thought that my 12 sub was blown but after thinking about it ,it's just being double fed .. getting very frustrated iv hooked up lot I'm systems in this one is the hardest by far
Will this work for a 2006 chevy trailblazer
Hey AVT. SO I put in a kenwood HU. And 4 pioneer 6.5 in the 4 doors. Wired up the HU to the factory harness. Jumped the blue/white wire to the pink in the 10 pin. Got audio. I know these speakers are great sounding but they sound so low. Is that because I'm going through the stock amp? I found the amp and unplugged it and yep no audio. Figured that. Any way all I want is my door speakers to work. I'm not putting in a sub. Which setup should I use? The one you did? I ask because you said you didn't care if your rear speakers worked. Just not sure. If it is how you did then I may just pair the wires together. Can you advise? Great vids btw.
My setup assumes a second 5 channel amp so it would not apply to you (unless I missed somewhere that you do have a second amp). When i said i did not care if my "rear" speakers worked, I was referring to the tiny tweeters in the way back (D piller). I was not referring to the rear door speakers. Those do work. Hope that helped
Did you have to use any pins from another harness? Or did the 70-2002 harness have enough pins?
this harness had exactly the right amount of pins
Question. Why can't you run the speed wire to the plug on the amp? plug it into the plug at the amp instead of the plug behind the stereo?? And how may channels does the amp ave to run those speakers??
If you are installing an aftermarket amp, you can run speedwire to the amp, or rerun your speaker wires directly to the amp. I have a 5 channel amp. One for each speaker and a subwoofer.
Will this work in a 2004 Escalade? I thought the box behind the glove compartment controlled the satellite radio functions?
not sure, but i am leaning towards no. you probably have Bose and 2003+ (for Tahoe at least) are different than my 2002
If i comepletely bypass my factory amp will my aftermarket stereo alone be enough to power my door speakers? Or should i still use the factory amp for the door speakers and my aftermarket amp for my subs.
Depends on the new head unit. I'd prob go with one or the other based on installation time/effort rather than performance if the difference is only trivial. You'd have to be more specific about your factory and new equipment if you wanted to get a specific answer though. Good luck on your project!
Hello Steve my name is walter I love your video, question if I bypass my factor amp! Do I need to get a cross over so I can use my tweeters? Because I want to replace all my speakers also. What's the best way for me to do this, and get the best sound.
there are mid-tweeter combo speakers that come with crossovers that you can plug and play.
Is this the same process for a 2003 silverado luxury bose amplifier? Im trying to bypass amp to install aftermarket amplifier.
i don't think so!
I have the same radio in my 03 Tahoe
Are you matching the positive and negative inputs with the positive and negative outputs?
You should sell these connections/ I definitely would buy buy for the bypass, use the vids and the product to get paid
I have a parasitic draw off that thing from Onstar...when I unplug everything...draw goes away...but I lose speakers...is that plug above it the onstar? can I leave just the speakers plugged in?
I'm not sure, someone else???
So..in response to one question you said yes your factory sub still works, then later you say it only powers the four door speakers. Which is it? I want to do this to keep the factory sub yet use the new head unit to power the four door speakers.
If done right, it can be reversed so the factory amp will work. However, once you apply the mod, the point is to use a better aftermarket amp.
You mention ur sub worked at the end of ur video with just using the Metra 70-2002 is that correct?
@Edgar - In my situation, I have an aftermarket sub plugged DIRECTLY into the aftermarket amp. In this case, you do NOT need anything besides the Metra 70-2002. Keep in mind that the D Piller tweeters will not work though.
IF you have an aftemarket amp and your sub is NOT wired directly to the amp, then you will need both harnesses as described on www.savagehomeautomation.com/projects/bypass-factory-ampcrossover-in-2002-chevy-tahoe.html.
Will this fix my issue on my '07 hummer H2? Added a after market amp and subwoofer...amp powers on but no audio....all my wiring are good...even my ground is good and bolted tight...still no audio through my woofer
no. 99 to 02 only.
Just wire nut your speaker wires to the wires coming from your aftermarket deck. much easier for us who dont like doing pins
Can i do this without getting an aftermarket amp?
Whats the top plug for? if you disconnect the bottom one what purpouse does the top plug serve?
those are the wires that go to the sub and rear pillar speakers I believe.
Do you know if a Tahoe or Denali amplifier fits a 02 Silverado trying to get better boom boom with my factory set up
Solid possibility but not 100% sure
I got it and found speaker wires and run them to a 4 channel amp but the radio turn on and say it miswired
Hello, do you sell this setup for my 02 chevy silverado 2500hd 4 door crew cab? Or is this something I can maybe figure out myself? Also does my truck come with this factory amp setup like the 02 avalanche? Thanks.....
the point of the video is so you can follow along and just do it.
Does this bypass work for the bose factory amp in my 98 infinity q45 , with the Metra 70-2002?
I have heard that it does not, but not 100% sure.
Is there a way to connect the back pillar speakers and sub?
Yeah, you can wire in a second harness as well that plugs into the amp to make the tweeters, D pillar speakers, and stock sub work as well. That was the first diagram he showed in the video.
Metra 70-2021 is the part number for one already made $13.26 as of Jan 2023. Not full proof. Gotta swap a couple wires around but apparently works.
With stock radio?
@@danielduncan8345 yeah I still have the stock radio in. I might make a video on it. So when I do I’ll send it.
So your saying installing that part , with stock radio , you will have sound out of door speaking ?
@@danielduncan8345 all 4 door speakers work yes. It’s wired the same way he stated in the video that he’s using
Hey, when using the Metra 70-2021, how does it effect the sub and rear d pillar speakers? Thanks for sharing btw!
Do u have to pull the pins? Can i just splice the wires to the pins without pulling them out?
That's what I'm going to try. I don't see why it wouldn't work.
Guud Shitt goin try that kuul bro
Peace be upon you, brother and friend, I am one of your followers. I would like to connect Salvador Radio 2001 to an external converter. How is the connection done because the external visa is available to the doctors? How do I know the hot and cold of the speakers?
I’ve talked to you before. But now I’ve replaced all door speakers and they sound great but when I turn up volume high they start to distort and crackle. I imagine it’s because I had the Bose system so I’m thinking the Bose amp is putting two much power to the speakers. Because I have a 200 watt double din deck now not factory. If I disconnect the amp will that solve my problem at high volume? And if so can I just disconnect it totally or do I have to bypass like you did
I don't know because mine was not Bose to start with. Hopefully someone will chime in.
Connect blue w/ white line wire to your red 12+ and it will bypass,well it worked for my 06tahoe and 10.1 android head unit. May be diff for your vehicle
What harness did you use to install the screen. I tried using a scosche gmo2b radio harness but powers up just no sound....2001 yukon, anythoughts
Dis you ever figure out the issue? I have a 2001 that is givin me some no sound problems
@@TrailingSkies27 i ended up giving up on all the harness and repin harness recommendations, and i honestly just ran new speaker wires to ech of the doors...
Where can i get acc 12v b+ on a 2007 chevy suburban on the harness has a red single wire apart. Thank you
no clue - try Googling it
This amp bypass was awesome. But they actually make a harness already for that. It’s the metra 70-2021. Plug and play. I just did one 2min ago on a 2002 Tahoe
U just saved me so much time thank u good sir
@@danielkruckenberg9882 np at all. 👍
Me too been working on this damn thing for three days now
Everywhere says it’s the 2000-2001 Monte Carlo/impala is that the correct one?
@@randymurdock2547 the harness? Oh what do you mean?
I have a 03 Chevy Avalanche 1500 with Bose. Will this same diagram work for my truck?
No
So I could run speaker wires from new radio down to that connector. That would solve all my issues because the 03 Bose amp only has two channels to the amplifier and does some digital fade?
My question is how did you make the double din fit? Did you just use the newer bezel and it fit perfect? I have an 01 Tahoe and wanting to get rid of stick radio but I know those are only a din and a half
The aftermarket bezel made it very easy as it fit perfectly.
Where did you find the aftermarket one from? I’ve heard the ones from the newer Tahoe’s fit like the 2004 to 2006 but I haven’t tried it
@@fmman5on Got mine at a local car stereo store.
@@fmman5on The 04-06 Bezel trim does work and is cheaper to get than the aftermarket dash trim.
Do you know if I could do that with my 2015 Dodge challenger with alpine 6 speaker system with built in amplifier? Everywhere I see they want you to buy a PAC Audio amp pro for like 375.00.
You have to use the pac piece to even get signal on that. Just spend the money and do it right the first time. So easy to use and works well, ive done many of them.
If I go this way, can I just wire a normal amp and sub in the back, bypassing having to get a speedwire and 5 channel amp? Planning to upgrade my 02' tahoe and hoping I can get away with a new head unit, amp, and sub. Thank you!
My plan is to physically remove the amp. Maybe even go far as removing the wiring.
I’m doing a full system in my 03 with Bose.
I’m gonna trace and label each speaker wire. And tap in them thru the back of the radio. Or if not I’ll just tap into them from the factory amp location. I’m gonna put the amp under the passenger seat anyways. So I’ll need a short run from my speed wires to the harness at the amp. I’m not tryin to revert to stock anytime soon. Lol Bose is nice. But much nicer set ups out there. It is a bit dated. It’s time for an upgrade.
Let me know what route you took. I plan on doing a full upgrade. So I’ll let you know how it goes.
@@Username-ng8jy I ended up getting a 2010 tahoe with Bose and put another amp and a 12’ sub into it, so I went a seperate way
@@nateweiner8890 ah ok man. That’s cool man. Hope you enjoy the ride.
I got an 2003 I got earlier this year. With the holidays coming up. And free time. I’m finally fucking with my tahoe. Just got my tranny rebuilt with sonnax shift kit corvette servo and upgraded converter.
Got carpet on order. And need to repair my headliner. I got a wood steering wheel I’m refinishing. Black Friday deals popped up so I’m ordering my sound equipment.
I have a 02 chevy tahoe and i want put a voice amp should i run new wires o use the one that it have
do you mean to the speakers?
Thanks Tom hanks
Chevy wiring is like a box of chocolates.
You never know if your gonna give up or not. My harness only had 15 pins all together. Did you have to make another?
Does the factory sub work with bypassing the amp my friends tahoe the stock sub doesnt work at all atm
No. My install involved replacing with an aftermarket sub and amp and wiring the 2 together directly
Hey quick question, so my doing this bypass would it cut the power to the amp? I’m asking this because I’m having my amp stay on and kill my battery.
Did you figure this out? My battery has been dead 2 days in a row after full charges.
Nicolas Brown yes It did I bought this bypass from amazon for like 10$ my problems was that my amp was staying not turning off, I recommend pulling the amp fuse if it fixes the problems buy the bypass, it’s cheaper than a used amp and it sounds 10x much better without it
