2014 - 2021 Toyota Tundra 4 Channel Amp Install

Parts used linked in the description below!
Watch a full tutorial as a 2016 Toyota Tundra will have a 4 Channel Amplifier Installed. We will be using the stock CD/Radio Stereo of which will be removed to allow access to speaker outputs in order to our wiring providing signal to the amplifier without use of an aftermarket radio.
NOTE: Our Tundra was not equipped with the factory JBL sound system, however, there was a small door speaker amplifier under the passenger front seat which was removed.
This video applies to Toyota Tundra models for years 2014, 2015, 2016, 2017, 2018, 2019, 2020, and 2021. This video also includes dash trim removal, complete amplifier wiring instructions, complete installation, and testing.

If you have JBL, you either need to manually bypass the harness or still use the Non-JBL Bypass harness above and re-pin the harness manually to match the output to each speaker. Here is a link to the forum where you can identify where each wire goes to: www.tundras.co...
If you don't have JBL or the SR5 amplifier under the seat, no bypass harness is required, just a simple T harness used in the video required if retaining the factory radio.

Thanks!Your videos helped me wire my 2015 Tundra. I ran into a few minor issues, but was able to correct them easily. The smaller male connector that goes into the radio was keyed differently but I just cut out the piece that was blocking it with a razor. The other harnesses for the plug and play hookups didn’t come with the extra wires for hookups for subs so I just soldered in new leads color for color with the extra 9 conductor cable I had. I wasn’t able to find pins and not too savy on finding car parts. Otherwise I would have just pulled the pins and cut and re crimped them with the extra leads. Other than that install went well. I really appreciate the help keep up the great videos.

[@ProvoBeastAudio]

Thank you!

[@julianjiron8085]

Hey thanks for the content you make!!! I have an aftermarket headunit. Im trying to wrap my head around the bypass you did in the video. Because i have a aftermarket headunit i would just run rca to amp then send signal to the door speakers using the already installed toyota wiring.... i think. Currently i have the amp bypassed because it did not work with the android head unit i installed. My question is why not just use the signal wires coming from the radio in the harness underneath the passanger seat to the amp's input then running the amp output to the speaker using the harness underneath the passenger seat? It does not make sense to me but im ignorant and dont know enough to understand why you need to do a bypass and make a new harness. Im just seeking to understand.

[@camoore]

Great series of videos!! Just finished my install and wanted to mention that the factory amp in my 2021 tundra needed a larger piece of ABS plastic. 16" was too short.

[@welshtexas1]

Did you use the T-harness recommended in the parts list? My understanding is this one does not fit the 2021 non jbl stereo.

[@camoore]

@@welshtexas1 Not sure if you found an answer or not, but you have to use a different harness. I emailed @ProvoBeastAudio and they sent me the correct info for my 2021 tundra non JBL.

[@Just_The_Average_Dude]

If I have an aftermarket head unit, how do I connect the 9wire? Will I have to splice it into the factory side of the radio harness? Also, could I just splice the factory amp input wire into the high-level input to the new amp and then the factory output to the new amps output? We went with a dasiata head unit and are struggling to connect the CT amp and bypass the factory amp.

The “new harness adapters” from Red Wolf do not fit the 2014 tundra. This route is a total wash if you’re depending on the harnesses listed. I have the 2014 SR5 Crew Max. Non JBL…with small amp under the passenger side seat.

Hello how about the rear channel on this toyota. there is usually very little bass on the rear channel. how do you solve it? if you have an amplifier, only the sound is amplified, but still a little bass in the back. ?please help

[@ctGONZOles]

The AX-DSP-TY2 did appear to be ideal for this setup. I’m looking to do both the 4 channel setup with a sub amp. Does the alternative Toyota T harness linked in description do the exact same thing? The connections don’t even look the same. The smaller male end on the alternative appears to be missing two wires (orange/extra green I think) but maybe those aren’t needed to get the signal to sub LOC/amp? Also can the center dash speaker bridge both the front L&R? Thanks!

[@gmiller10304]

@provobeastaudio hello, really enjoy your videos! can I use RCA's to go from the head unit, Alpine iLX-W650 with front, rear and sub RCA outputs to a CT-800.5D? is there a disadvantage to using RCA's? thanks! Gerrit

[@Swindy1794]

How could you not want a DSP?

[@purplerandy]

Why do you make another harness to go from the radio down to the amp if you have already bypassed the original amp wiring. Sorry I have watched this video 10 times trying to draw out a diagram of what harness goes where and I get lost. One end plugs into the radio so where is the signal coming from the radio or after the bypass loop that goes back up to behind the radio?

[@user-he1id9hl6z]

I am thinking about upgrading my system, but am confused about what channel amp I need. What is throwing me off is the center speaker in the dash. Was wanting to run 4 Kicker KSS670's, and replacing with a Kicker KSC350 for the center, and running a dual 10" 1,600W sub set. Do I get a 5 channel amp with a mono? Just not sure. Trying to figure this out on my own. Any input is very much appreciated!

[@juliomoto70]

How Is Alternative T harness connected? Just plug and play? Witch cables from the harness goes to the Amp input? Can you specify how to connect the complete harness?

[@gamescube]

It’ll be great if you help me out. I install the same way you did but the only difference is that I have LOC 4 channel and same stock radio. Biggest problem I’m having is static noise coming from all speaker. I even bought those noise canceling filter out but still resolved my static/buzz noise

[@ProvoBeastAudio]

Send us a message on facebook / instagram and i can assist.

[@alfredolovesruby]

Do you need both harness for the amp bypass and the t harness so under seat amp has the same wires that goes back to the radio rigth getting the signal from there instead of running the t harness will work or be better

[@jorgebadillo8755]

Question here so i just wanna upgrade the amp and door speakers easy enough but ive heard like u mentioned its mids and lows at the door i want a full rane threeway speaker will i have that singnal at the amp harnes coming from the headunit ive heard the headunit has the “filter” so no and ive heard the amp has the “filter” so yes u can wich is it ?

[@WCxColosus]

It would just be easier to buy an amp that can take high inputs, then you wire the radio inputs to the high inputs of the amp. Then you wire the outputs, these are wires going to the speakers, and wire them to the oupts of the amp. Saves time pulling the radio out. Also if you have a amp that dosent have high inputs then you can a LC7i but this is the more expensive route.

[@user-ho6xs4hc6v]

Hello sir I hope you can help me im doing the same install and I made my t harness and im not getting power to my head unit when I connect I didn't connect the constant or ground but I connected the 12v what is it that im missing? Thanks in advance

[@newlifely7849]

You should make these and sell them.

[@IPACA9]

Was the center channel still functioning after this?

[@juliomoto70]

Now the amp is powering all seven speakers? The four doors speakers, the two dash corner speakers and the center dash speaker also?

[@ProvoBeastAudio]

Factory non JBL amp only powers door speakers 6x9 and 6.5". all tweeters (3 dash, rear doors) are powered directly by the radio.

[@juliomoto70]

Thanks But the new amp will power all speakers or just the speakers doors?

[@ProvoBeastAudio]

@@juliomoto70 All speakers as we bypassed the factory amp wiring.

[@joelmunoz8899]

@@ProvoBeastAudio this does not make sense. You should show the wiring for the tweeters behind the radio. Some components speakers run a bigger crossover for both the door speakers and tweeters. I’m just confused that you didn’t show the separate wiring for the tweeters?

[@ProvoBeastAudio]

@@joelmunoz8899 It's because we we sent our amplified signal back into the main harness behind the radio, not at the amp bypass. We didn't run new wiring for tweeters (see that video linked in the description). This ensures all speakers receive the amplified signal equally. Our new aftermarket tweeters have an inline crossover, so no separate crossover was needed. It would make a lot more sense for you if you saw the front door speaker install video linked in the description of this video.

[@olivergalman7319]

I bought the AX-DSP-TY2 and it doesn't fit my plugs behind my stock stereo. Can you help me out please!

Do I have to do anything different if I have the JBL system?

[@DC-kl2ce]

Super informative, thank you! What would i need to do differently with the harness (if anything) if i am installing a 5 channel amp to be able to run the subs as well? (everything off one amp) Thank you in advance.

[@ProvoBeastAudio]

If your 5 channel amp can simply just take 4 channels of input (sub snags signal from the other 4 channels), you can use everything linked in the description.

Thanks I found the video i was loo at your website and it say that y’all can prepare the harness for $49.99 …and another question if I get a Tesla edition radio do I still need a harness to connect an amp with subwoofers ?

[@ProvoBeastAudio]

Yes, we can assemble your harnesses if you ship them to us. You will still need an amp kit to install an amp and sub to any vehicle. The only difference is you won’t need a line out converter as the new radio will have a sub output.

[@Barloshdz]

Quick question would I have to still bypass my oem amplifier even if I have an aftermarket radio? Just looking to install a 4 channel just like you man. Nice video btw

[@ProvoBeastAudio]

Yes, the only difference is you would run RCA cables from the radio to the new amplifier. For your audio out, just use the bypass harness we used to loop in all your speakers, and use a run of the 9 conductor cable up to your main wiring harness behind the radio, disconnect your radio speaker outputs, and connect in your new speaker 9 conductor cable to the wiring harness adapter.

Amp powers all door and dash speakers. If you went with a 5 channel amp, it can also power a sub. If you want more details, send us a message on facebook or instagram and we can help.

[@garrettray7784]

How much of this process would change if i were to buy and install an aftermarket head unit?

[@ProvoBeastAudio]

Instead of a T harness, you would run RCA cables from your aftermarket radio to the amplifier, then your 9 wire from the amp to the radio harness adapter that connects into the vehicle. Then simply cap off the speaker wire outputs from the aftermarket radio.

[@whimcreations8888]

If you upgrade your amplifier to an aftermarket amplifier. Do you have to upgrade the wire going to the speakers to handle the amplifier output?

[@ProvoBeastAudio]

Depends on how much power you are pushing. Generally Toyota has copper wiring running thoughout, and they can handle up to 100w RMS over that 18 gauge copper run. So any more power than 100w, you will need to run new wiring.
