BYD Custom Stereo - Part 2 - Connecting Amp And Speakers

[@BluntUnicorns]

I quite like the fact that BYD added a concentric twist to the audio cables in the factory loom. Nice touch. I like your workmanship. I could say more, but would hate for my commentary to be perceived as criticism. You have a good understanding of what you're doing.

[@Wayne-Grincais]

Love your work Paul, Im at that stage where I am thinking, do I jump into an EV yet or not. your video's have almost talked me into the BYD. Thanks for sharing your work and knowledge with us.

[@TallPaulTech]

Well I'll say this, the BYD Seal has been pretty straight forward and logical as far as it's put together. It doesn't look like they're trying to do everything themselves and reinvent the wheel like Tesla. Also, given that pretty much everything is made in China, I don't know why people are getting upset about a car made there.

[@crispin.]

Haha ace videos and quality workmanship! Greetings from London. Love the fact you've got a 24 bit/96 kHz quality DSP and you could stream 24-bit lossless ha ... that's gunna sound better than most peoples front rooms lol

[@TallPaulTech]

Indeed it does. I honestly think a lot of people don't know what quality can be if they've never heard it.

[@TallPaulTech]

I got the car a month ago today.

[@yhakult]

Possible to still use steering wheel controls?

[@stewartlanghorne7598]

Where do you find the pin outs for speaker info ? Trying to find some for byd dolphin speakers

[@TallPaulTech]

I pulled the plug out of the amp and tested which speakers they went to, as I showed in another video.

[@theonlywayisrecords4980]

Could you kindly share the cable colours and polarity on what’s pos or neg for the phase. It’s just I attempted today and had to use a 9v battery to pin the cables to work out what speaker is what but unsure on if the stripped cable is the negative and the solid colour is positive like on standard speaker cables. Thanks

[@TallPaulTech]

Don't use a 9v! Check out my other video where I went all through the colours

[@theonlywayisrecords4980]

@ can you send me a link please, also dose the tweeters require a additional amplifier or can they be run inline with the door speakers or will I need to make a crossover for the tweeters or do they have a cap installed. Regards

[@felixthecat1672]

"Slanty" Classic.

[@OutOfSync382]

If you put some load in the 5v output on the PC power supply, the power in the 12v output will increase. Nice work!

[@MrKennethho8181977]

May I ask where can found the ACC / REM signal from BYD Seal?

[@TallPaulTech]

From the fuse box. Check my dashcam video

[@KieranShort]

Ahh it makes sense now what you're doing with the stock speaker wiring and also feeding in some of the factory audio as an option into the head unit - to mix in the incessant blips if you need to (for whatever reason). I love that you installed the head unit underneath the passenger seat, that's a real dead space in most cars. Is there more room there for other gear?

[@TallPaulTech]

You mean the back seat. That's all I plan on going there.

[@KieranShort]

@@TallPaulTech sorry, yeah, back seat... it's been a long day.

[@deserialized]

Stupid question - but for a average user - what if the speakers are just fine but the problem is the amplifier. So if you just upgrade the amplifier and increase the related fuse. What do you think about that if I do not want to touch the existing wring too much? I am mostly worried about the output volume rather than the quality of the system.

[@TallPaulTech]

It's probably actually a problem with the factory source to begin with.

[@jamesc7400]

I have not done anything like that for many years. As things keep changing, just wondering if an installation like this affects the warranty of the car at all.

[@TallPaulTech]

It's a stereo.

[@iNireus]

Will you be super glueing the TosLink as with road vibration the TosLink connectors are bound to fall out? They do in my home if knocked though they are ancient

[@theonlywayisrecords4980]

Honestly thanks for the videos they have helped so much in gathering information and given me more confidence in doing a similar install. Probably an unknown question but how many amps do you think you could pull on the DC converter. I’m hoping it’s more than 100amps at least 😅

[@TallPaulTech]

I don't even that that much in total fuses on the amps, and they are powerful. I put the 10 Farad capacitor in there though, let's not forget that.

[@lelopissetti]

Hey, how are you? Have you done any project to the BYD Song Plus model 2025? If so, any problems/interferences with the noise canceller? (If yes, how did you solve it?). I'm in Brazil, done some changes to and Alpine system, but we are having trouble with the noise canceller.

[@TallPaulTech]

I've only worked on my own car. Have you put an Alpine system in yours too? I'd like to see it

[@lelopissetti]

@@TallPaulTech once we are abble to solve the problem within the noise canceller, I'll send you a video :)

[@felipepersona]

Congratulations on the project! One question, do you know how many liters the original subwoofer box holds?

[@marcsaispas5496]

Hi from France…great video….

[@TallPaulTech]

You're up early

[@rolly4x4]

An easy way to tell the polarity is flick a 9v battery across the terminals. If the speaker cone jumps out the positive and negative are right, if the cone jumps inwards they are the wrong way round.

[@TallPaulTech]

That's a bit extreme... wouldn't need a 9 volt. Anyway, that would require me pulling the doors apart, at which point I'd be able to see the cable visually anyway.

[@KieranShort]

Yep, I did work experience in 1992 in a car audio place and they did the 9v battery trick so that's what I do. It's so easy.

[@TheAVJedi]

A better, less damaging to the speakers method is to use the tone generator from an F-Set. Like you would use in UTP cable tracing.

[@rolly4x4]

@@TallPaulTech can be done with an AA or AAA too, just a bit easier to see the cone jump with a 9V.

[@rolly4x4]

@@TheAVJedi I have never damaged a speaker with this method over 30 years or so of installing car audio.

[@erbutsludge]

Crimp vs solder. Crimps take up a lot of space and doesn’t look neat but could be staggered to take up less space. Solder can look better and compact but can be brittle if subjected to movement/vibration. I worked on systems with removable panels, we were constantly repairing the soldered joints. Soldered joints need to be completely demobilised in some way otherwise you might need to repair later. Just my experience.

[@TallPaulTech]

Soldered joints are fine really, as all of the electronics in the car are held on by solder. The main problem with solder is for heavy components, which you'll notice usually have glue over them. Cable to cable won't be a problem. As I said in the video I just used crimps for a quick and easy to get it running for now until my heatshrink arrives.

[@Kieran28]

Nice job! I’d find a way to bypass the screen with a pi, you could have full control then

[@TallPaulTech]

Believe me, that thought has been on my mind since day one

[@gijskummeling]

Thanks for all the work and showing us! Maybe I missed something, but how do you drive 12 speakers (that were originally present) with an 8-channel output; and drive 2 subs with the M1D which is 1 channel? Was wondering which furthermore amplifier you would recommend if one is more fan of class ab sound?

[@TallPaulTech]

The centre dash speaker and back parcel speakers are useless, so they're out of the equation. 8 channel amp for 4 doors, mono for the subs.... the real subs. The box for them is looking good, and there'll be a video on them and the amps soon enough.

[@gijskummeling]

thanks, that's good to keep in mind. Might take my own Seal for the upgrade to a garage, not as much a handyman as you are. Will stay tuned regarding the amps!@@TallPaulTech

[@cromulentparty]

The stock speakers are Dynaudio?

[@gijskummeling]

yep

[@alessandrocannarile]

Hi man. Nice videos. Love what you are doing for the community. Few questions: Name of the apps showing in the videos? (meteo tv...) When you are using the hilvl from stock stereo the volume is lower or not? I am looking for a similar solution but i want to keep stock sub and stock speakers in general (also center and rear speakers) I want to add/swap only an ampli. What do you think will be the best solution for this job? Audison forza m12.14 (stock sub will be underpowered?) Audison forza 8 channel with some bridging since it lack 4 channel? (maybe in combo with stock ampli?) Really looking for your help mate :)

[@iNireus]

Nice one.

[@czLochy]

Ahahah, I love everything about this, amazing job mate, really like this mod, cool as all fuck!

[@TallPaulTech]

It goes alright

[@No_soup_for_you]

Go da Propellerheads! Decksandrumsandrockandroll’s a great album.

I don't know about the whole album, but that track for sure.

@@TallPaulTechBeing a music man, it’d be right up your alley. 👍

[@henvan8737]

A silly question, did you perform these sort of mods on your Tesla.

[@TallPaulTech]

I assume you did not watch the video

[@TradieTrev]

Very tidy! You'd get a job as an auto sparky any day of the week but you'd vomit at the pay packet.

[@TallPaulTech]

I'm going to eventually solder and heatshrink those cables. As you can see, it's far from done. I have to come up with a creative frame to house the 2 amps and capacitor on the right there.

[@jarnokylander490]

As Homer Simpson said it: If it's worth doing, its worth over doing! I just love your attitude and workmanship. I also chuckled when you mentioned raspberry pie...😂😊

[@TallPaulTech]

The Raspberry 3.14159... Gotta have a go at these things

[@AZ-hj8ym]

Will you add solor panel on your car. That would be much more fun to watch!

[@Cybernetic_Systems]

The 90’s called, they want your subs back! 😂 Great work tho mate, those BYD noises sucked hard!

[@AnarchyEnsues]

Ludicrous feed KZbin channel who reviews ev cars in Australia, he asked byd, and they said you will be able to disable all the "driver aids" and it will save your settings in a coming update, allegedly it was all for ancap, but I think it was just bad programming, as iv got a new cars that are both 5 stars and they remember your driving aid setting.

[@familyplans3788]

People really moan about how you cut speaker wires ? I'm sure there are forums they can join to help them with their problem

[@TallPaulTech]

Mate... it's sad out there!

[@henvan8737]

Great video but looks an expensive mod.

[@tcpnetworks]

I cringed when you butt connected.... But it's your car - so I'll stay out of it.
