    What type (brand) noise suppressor do you recommend?

  2. gamer 123 on September 23, 2021 at 12:07 am

    I connected my stereo but it heats up from the back. Any advice?

  3. Arthur Miller on September 23, 2021 at 12:09 am

    Thank you very good I like

  4. T W on September 23, 2021 at 12:09 am

    Ok, that was a pretty shitty explanation on how to make connections without soldering. You showed 3 coloured tubes… and did nothing to explain how they work or how to use them. Not helpful.

  5. Glenn Smith on September 23, 2021 at 12:10 am

    I was hoping to learn about steering controls and the wire colours for this.

  6. MANTIS on September 23, 2021 at 12:11 am

    So I bought an adapter for the aftermarket stereo but it doesn’t say accessory. What do I do now?

  7. Isaac 84 on September 23, 2021 at 12:12 am

    Hey guys! I have an aftermarket radio installed and don’t have power in the factory amp/subwoofer. Any thoughts on the solution? Speakers work but not amplified subwoofer.

  8. Joe Foss on September 23, 2021 at 12:13 am

    I am simply trying to take a junk-yard radio from a 2014 Explorer and put it in my police 2014 Explorer and make it work. I changed the mounting Brkts, but when I plugged it in it would not tune or change frequencies and there was no audio. Seems that the cable plugs-in OK to the police car cable but will not tune and there is no audio. What do I need to make this swap work?

  9. vvv dog on September 23, 2021 at 12:14 am

    nice work i do the same thing

  10. Kimberly Sadler on September 23, 2021 at 12:16 am

    How do I bypass the camera wires (“front camera” and “back camera”) I got the boss bv755b but I don’t have a camera yet.

  11. Rick Peou on September 23, 2021 at 12:17 am

    hi there i’ve got the clarion XC2410 amp just wondering where can i connect the blue cable to please

  12. James Bates on September 23, 2021 at 12:19 am

    I’m seeing more availablity of more advanced interfaces in the USA compared to the UK ..Your Maestro Rr system and our connects2.

  13. Kyle Maldonado on September 23, 2021 at 12:19 am

    My 93 ranger has illumination and dimmer wires but the aftermarket unit I bought doesn’t can I just tape them off? I also have a radio ground and chassis ground can I connect them and attach to the single aftermarket ground wire?

  14. William P. on September 23, 2021 at 12:21 am

    Does anyone know where the factory amp is for a 2017 sentra? Ive checked everywhere literalmente

  15. Dan Desjardins on September 23, 2021 at 12:21 am

    Good video but what do I do imy interface has orange but my pioneer stereo doesn’t will that effect anything

  16. Zack Rozelle on September 23, 2021 at 12:21 am

    hi I’m having a problem with a Boss Audio amplifier, I put it in my truck and it has the rock, class,flat,pop, and eq off settings. When I have it in every setting but eq off all 4 speakers work, but when I have it in eq off only the drivers side works, could you tell me what’s wrong.

  17. tturi2 on September 23, 2021 at 12:21 am

    What about pinning it all to a matching number of pins connector?

  18. Mujahid Ahmad on September 23, 2021 at 12:23 am

    Nicely explained. 👍👍

  19. Ted Tremendous on September 23, 2021 at 12:24 am

    Great Video! Is there any point to taping the wires? I never have before, they will not be seen so not really needed right?

  20. Arthur Miller on September 23, 2021 at 12:25 am

    I do like tips on crimping the wires with the butt connectors I’ve never liked butt connectors because it’s very hard to get a very tight connection with them I know it can be done but it’s not always easy and you got to have good crimpers too I like that trick and been in the wire I never thought about that very good

  21. Dublin Vid's on September 23, 2021 at 12:27 am

    Hello,
    I installed aftermarket radio in my VW Golf TDI 2008, I am having one issue, Before installation of new radio the bass and sound was very good in Original old radio, but when i installed new aftermarket radio the Bass is not good i think factory amplifier is not working with new radio, i replaced it with old one and the old one is working perfect but i want to use new one, can you please help me with cabling, i think i did something wrong while cabling. one blue wire i connect with radio antenna. Please any suggestion.

  22. Jim McCarron on September 23, 2021 at 12:27 am

    Don’t suppose you know how to connect a ducatto van to a seicane media unit there’s no instructions with it and can’t get any help from the company

  23. Mauricio Salmoran on September 23, 2021 at 12:28 am

    Soldering is absolutely not needed in 99.99% of cases. You are actually much more likely to end up soldering incorrectly than any properly installed crimping. Soldering is a somewhat difficult skill with needed equipment to hold the wires, as shown in the video, and doing it wrong could lead to sharp edges that could tear through electrical tape and short circuit your system. Your stereo stays strongly connected to your dash there won’t be any pulling so why even act like this would be an issue? For the majority of you reading this save yourself the trouble DO NOT SOLDER and twist your wires then use a single end crimp. It will not come apart and will save you much time and stress. Bonus points get proper crimps from your local car stereo store not the cheap Walmart versions shown in the video. If you bought the stereo from them there’s a good chance they will throw them in for free.

  26. Arthur Miller on September 23, 2021 at 12:35 am

    Wow very good I like how you take the time to to explain everything that’s the reason why a lot of YouTube videos are not any good because they leave out a lot of information this is very good I really like it thank you

    Just let yall know, soldering is overkill. You can twist the wires then heat shrink and your good.

  30. Davin D'Amico on September 23, 2021 at 12:38 am

    Hello, nice video and all, but where is the ignition wire supposed to connect to now that databus turns on the unit?

  31. boodah808 on September 23, 2021 at 12:39 am

    If my stock stereo doesn’t have rca input plugs in the back is there an interface device that connects to the stock stereo and I could plug my rca cables in there?Because I’m trying to install my subwoofers but my stock stereo doesn’t have a spot to plug in the rca cables and remote wire,I have a 2018 Camry de and it’s hard to find stereos for that model

  32. 1blairw on September 23, 2021 at 12:39 am

    I connected yellow (constant) to yellow and red to red wires, like every other stereo I’ve had, but an Alpine UTE93 drains the battery overnight. What can be done in such a case?

  43. turbocut on September 23, 2021 at 12:53 am

    Legend !

  44. aReal Nigga on September 23, 2021 at 12:54 am

  46. Endoe Kronic on September 23, 2021 at 12:58 am
