If your sedan has a speaker in the rear deck, it should be straight forward. I had a sub&amp installed in my ES with 12V feed directly from the battery, and it was sensing off of a rear speaker with splice into a wire there through the trunk. Amp was mounted to the back of the rear seat and sub sat in the trunk...

Otherwise if it is like hatch, with speakers only in doors w dash tweeters, I will be tapping into the rear door speaker wires most likely under the seats...

 

hello, just wondering.Where did you run the power through the firewall? I will be installing an amp next weekend and trying to see the best location to run the power through. Thank you

 

Have you looked at a electrical wiring diagram?

 

Well the car is so new I haven't seen much material about it. I had to take off the door paneling to determine the speaker size. No place online has indicated those dimensions.

I did some testing with the factory radio to determine which plugs controlled what so I know which one outputs audio.

Something new with 20s at least in the sedan body is that there are no longer rear deck speakers, just a hole for the JBL subwoofer when you go with the audio plus package.

 

I had to take off the door paneling

oh wow you did that to spanking new car...and you did it w/o published service info ?
The lock actuator in my old Acura went out and from the service manual it looked like a big pain-in-the-neck job to pull open the panel so I didn't bother with it.

 

Today I installed a sub into mine - hello bass (aka base )!!! The wires in the B-pillar are pink and purple for the speaker if you want to use them for audio sensing...

 

How long and how much work did it take you roughly, some company’s tryna charge me 900 cad bucks to install my 2subs and amp in my 19 corolla hatch , seems a little steep but I don’t know much about car audio

 

Good to hear. I'm getting ready to just replace the rear doors today. Easiest thing to do at this point. I find not many of the wires match color wise to anything from the radio. Truly maddening.

 

EDIT --
Removed previous message to avoid confusion for other members.

Incorrectly indicated polarity of rear door speaker wires.

To correct, violet is + and pink is -. My speaker clip had a mark on pink input to indicate negative.

 

So the rear door speaker wire are as following a light purple coating with a pink line for + and dark purple for -.

The other way around: violet is "+" and pink is "-"

 

So I did end up upgrading my audio, well I paid someone to do the work an it took them a lot of troubleshooting and research to figure out how to work with the front speakers. Stuck with the factory radio. Easiest option at this point.

They made the splice after the bluetooth/phone modules. There's a series of connectors the front speaker wires go through. They got the schematics but they were not so accurate.

JL speakers all around and sw
Kenwood Excelon amp
Kicker Front Row DSP

I'm pretty satisfied but for my personal taste I'm going to adjust some of the crossovers. Just too much low-end spectrum for my tastes with the music I listen to.

 

 

Check out tacotunes.com they make a complete color coded harness that plugs into the back of your factory stereo and hass 11foot lead wires so you can wire in subs and amps without having to cut into you factory harness or wires on ur new car!!! i just did it with my 2020 corolla sedan!!! its simple and easy ifneed to goo back to stock for warranty purposes it simple just un plugging the harness. Ull have to look up the 2020 camry harness wich will also work for the 2020 corolla sedan

 

In the process of upgrading my system. I also got my head-unit speaker harness and tweeter/door speaker harnesses from them. Still have to confirm if the door speaker harness is compatible.

 

i was a little peeved when i noticed no rear speakers but you have rear speak controls. i'm fairly pleased with the sound it produces i would like a little more bass and certainly more sound in the rear for the passengers, although that isn't a deal breakers since that is like 1% of the time. i talked to an audio shop they wanted 1k for a replacement. and i'm not about to pull my new car apart. im not nearly as brave as you sir.

 

Here you go

 

Thanks, and this works well in your Corolla 2020?

 

it's very strange I was talking to tacotunes support and nobody can tell me if that harness works with the Corolla 2020, but if it worked in your car I believe you

 

Srry it took so long to answer I forgot the harness model number from tacotubes but it was for the 2020 camry and it works great in my 2020 corolla sedan door speakers subs sounds good aNd didnt have to cut into anyof my factory wires so itll be easy to go back to stock

¡Hola a todos!

Recientemente me robaron el 09 S, así que compré un 2020 SE.

He separado parte del tablero para verificar la situación del audio y no puedo identificar los cables.

Desde el mazo de cables del altavoz tiene dos púrpuras y rosas, luego una serie de púrpuras claras con rayas: *****, verde, amarillo y azul.

Los parlantes de las puertas tienen un tamaño de 6.5.

Solo busco más información ya que estoy interesado en un amplificador y altavoces del mercado de accesorios mientras conserva la radio de fábrica. Siéntase libre de compartir el descubrimiento de audio aquí.
[/CITAR]Hola amigo ya sabes cuáles son los colores de los cables de los altavoces traseros ?

 

Both rear speakers are purple(+) and pink(-), it changes to Lavender/Purple stripe(+) and Lavender/Pink stripe(-) at the speakers. RL uses pins 3 & 8 and RR uses pins 4 & 9 on the head-unit speaker connector (black 10 pin connector). For reference, pin1 FR+ (Lavender/Yellow stripe) and pin6 FR- (Lavender/Black stripe).

Hoy instalé un submarino en el mío: ¡hola bajo (también conocido como base : geek: )! Los cables en el pilar B son de color rosa y púrpura para el altavoz si desea utilizarlos para la detección de audio ...

Hala amigo me puedes decir el color de los cables de los altavoces e las puertas trasera de un Corolla SE 2020

Luis porque no usas el Harness que yo estoy comprado en Tacotunes.com, asi no tienes que identificar nada solo lo conectas y ya, de alli sacas los cables que van al amplificador, mira el hilo de la converzacion mas arriba

 

Ambos altavoces traseros son púrpura (+) y rosa (-), cambia a la banda de lavanda / púrpura (+) y lalavanda / rayas rosas (-) en los altavoces. RL utiliza los pines 3 y 8 y RR utiliza los pines 4 y 9 en el conector del altavoz de la unidad de cabeza (conector ***** de 10 pines). Como referencia, pin1 FR+ (lavender/raya amarilla) y pin6 FR- (lavender/black stripe).

 

Luisportillo22, I don’t speak Spanish but I’m trying to help with the aid of an online translator.

 

Hi i need same info for the front spikers 2019 Toyota Corolla hatchback pasanger side is not work anymore im getting crazy looking why the spiker is not work but everything is fine i look something weird maybe is the problem a purple cable lake went something is getting too hot bud im getting crazy

 

I was wondering if anyone know the power output for our corolla stock head unit. I am thinking just to upgrade the speakers first to see if there will be an improvement over the stock speakers. But I need these output number so that I can buy the right speakers . Thanks.

 

18W RMS unclipped output at volume 45. Only measured the front outputs, rears are around -8db. 1khz at 0db test signal, same results at 50hz.

 

I have read somewhere that it is 4x18W.

 

Really? 4x18W, really? No wonder they don't sound that good. I don't think it will make any difference if I only replace the speakers I guess. Thanks very much for the info.

 

I wouldn`t bother changing only speakers. You will need an amp for good result. But in any case we are limited with quality of headunit, it is really strange to me that there aren`t any plug and play aftermarket replacements yet...

 

I've seen a few Alpine head units look exactly the same style as our corolla unit, but I am not quite sure if they plug &play replacements and they are quite expensive. But I also like our head unit as they have volume knob control that most of the aftermarket don't.

I think I have to get an amp and speakers installed by the car stereo shop. They told me it costs $450 AUD just for the installation of the speakers, it costs more than the cost of the speakers

 

Anyone have a picture of the radio wiring diagram for the 2020 toyota corolla se (without jbl)?, im wanting to install the JL Audio Line Output Converter, but i dont know which 2 wires I can splice into to get the +12v (positive) and the remote out..

 

Battery power (pin 4) is the wire opposite to the ground wire (white with black stripe, pin 1). The remote out is used to turn on the equipment downstream of the LOC. The LOC uses signal sense to turn the unit on.

 

Do you know the color of remote wire (ignition wire)? thank You

 

To my knowledge there's 2 places to run the power through.

Steering column under the master cylinder and on the passenger side where the ECU sits.
