    i recently had an amp installed and shortly there after i noticed a cloud of smoke inside my car. the smoke smells bad, like burned goat shit, and makes you want to puke. the smoke is coming from my car stereo, not the amp. the installers tried to blame my LED bulbs but i told them the lights only turn on when i open the door and thats for a few seconds at a time. i replaced the bulbs with OE bulbs and the smell of burning wires is still there. what is causing something to obviously overheat?

    Good video straight to the point you just got a new subscriber

  3. Kappawaii on January 18, 2021 at 5:28 pm

    So I bought 4 speakers and I want to get an amp for them but idk what wattage I need and if I need to get a converter as well. I also got a stronger subwoofer 2,000 peak power but idk what amp I should get with it.

  4. Arun Amul on January 18, 2021 at 5:28 pm

    I have 1000 watts class AB amplifier. What wiring gauge i should use and fuse capacity

  5. c0uchsl0uch00 on January 18, 2021 at 5:29 pm

    If im going with 0awg power & ground is it manditory/necessary that i do the BIG 3 with 0 guage or can i skip that part?

  6. Corey portelli on January 18, 2021 at 5:29 pm

    I love you videos, you do such a good job with them.
    I live in Melbourne Australia and am putting a car stereo in my car, I am using your videos as a bible.
    Thanks for shearing your knowledge.

  7. Paul the Car Whisperer on January 18, 2021 at 5:29 pm

    How do you know what size wire to use to run to the speakers?

  8. Real N on January 18, 2021 at 5:30 pm

    Question can you connect a universal bass knob with a stock head unit? Thank you

  9. Dan Cosmin Marza on January 18, 2021 at 5:31 pm

    have you used bnc to rca cables ??

  10. Anthony Gutierrez on January 18, 2021 at 5:31 pm

    I use jumping cabels to my power n grown…100% copper..

  11. DLAROC on January 18, 2021 at 5:33 pm

    Is it ok if my power wire is 8 gauge but my ground wire is 10 gauge regular wire i bought at AutoZone? The 8 gauge ground that came with my kit wasnt long enough.

  12. Joe Paul on January 18, 2021 at 5:37 pm

    Hello Mark , my name is Joe . Wanted to thanks you for such informative videos . I am 60 years young and have installed many of my own systems , but I have to say watching your videos has awakened me to many new routes to go . Thanks much for all your videos and hard work . God Bless you and your business .

  13. George orge Orge on January 18, 2021 at 5:38 pm

    Sir do you have size box in 10inch subwoofer speaker?pls…help me…

  14. Ricky Ruvalcaba on January 18, 2021 at 5:38 pm

    Do you need a better head unit to have better quality and louder sound for your subwoofer and amp?? I have a stock head unit currently

  15. IndyStreetRacer on January 18, 2021 at 5:40 pm

    I’d like to know what other single strand types of wire you use. Like what you use for remote turn ons.

  16. Ian Summers on January 18, 2021 at 5:40 pm

    A thought on the power wires you showed in those kits…

    In any conductor, excess positive or negative charge accumulates at and distributes itself across the surface of the conductor so that charge density is nearly uniform. This is because like charges are repellant (and unlike charges tend to pair off and neutralize). So the point being, in any sort of conductive object, positive or negative charge will travel along the outer surface. This includes electrons traveling (i.e. "current"). In simpler terms, current travels on the outside surface of your wires. Where I’m going with this, is that if you have a tinned wire…the resistance of that wire is largely going to be determined by the plating. So oxygen free copper, versus regular copper, whatever… the resistivity is predominantly dictated by the plating on the wire. I haven’t looked up the resistivity of different metals to say concretely, but I would hazard a guess that your best value is to not worry that much about what sort of copper it is, and just buy the absolute fattest wire you can reasonably afford (provided that girth is metal, not insulation). Only once I was down to zero gauge wire would I worry about alloy at all, and even then, only if I was some sort of SPL competitor trying to wring every last dB out of my amps. Your ROI of money and attention is bigger elsewhere IMO.

    Theory is one thing, but actually getting to see you apply knowledge to create these systems is really great. Thank you for sharing your considerable fabrication skills and knowledge with all of us. I am learning a lot about installation methods, materials and best practices from your videos.

    Hello There. I do planing use 4 channel 720W amp but using 4ohm speakers so its 4x60w – 240W not 720W at 2ohm do I have to use 720w or 240W to calculate what wire to use? same think for my mono 320w amp for sub 320W or 150W bridged at 4ohm both AB class – Thanks!!

  18. Bob Riddle on January 18, 2021 at 5:41 pm

    That covers it good Mark, that much info won’t come from a question or two when just starting out.

  19. Oscar Alvarez on January 18, 2021 at 5:41 pm

    You should check out heat shrink by ray chem, it has adhesive inside the tube to seal it

  25. Orven Harry Panem on January 18, 2021 at 5:53 pm

    Sir can you help me. What would be the best fix speaker wire gauge for my 70wattsx4 class ab speaker and 250 class ab mono amp? It will be fit on a hatch back type car. Your input will be a big help. Thank you in advance.

  26. Nikkil Alexander on January 18, 2021 at 5:54 pm

    Hi Mark, I’m a great fan of your videos. I got a lot of important tips from your videos. Thank you.
    I’m going to start a new project for my car. Got an amplifier "sony xm-n1004" and speckers "sony Xsgs1621C". I live in Italy and I’m having a lot of difficulties to find the right gauge ofc wires. Can you give me any tips for my project please.

  27. Richard Garcia on January 18, 2021 at 5:54 pm

    Will poor quality RCA reduce the loudness of my system, if so how much of an effect?

  28. Eric Chavez on January 18, 2021 at 5:54 pm

    can you do a video on how to 3 remote wires or the best way to do this?

  29. Hayder_jz on January 18, 2021 at 5:55 pm

    Thanks god for the plenty copper available in my country’s ground, main wire 4 meters for 10$ usd

  30. pritish0071 on January 18, 2021 at 5:58 pm

    Hi, could you please suggest what awg wire is good for speakers.. 14 awg or will 16 awg do!!

  31. Carl Rodin Mannerstål on January 18, 2021 at 5:59 pm

    Will one of these kits work if i have 2 diskants 4 6 inches and 2 12" subwoofers with one 3500 amplifier and one 600 amplifier??

  32. Christopher Gott on January 18, 2021 at 6:00 pm

    I just got my shipment from KNU today and I wanted to give people a heads up. I ordered 12ga. speaker wire for the doors and rear, and 8ga. for my subs. I got the Karma SS line and they’re freaking HUUUUGE, LOL. The 8ga. is damn near the size of 1/0 welding cable. I have NO clue how I’m going to get the 12 ga. wire through the drivers side door. It’s close to 4 ga. wire in size and I have an ’03 Taurus that has the stupid hard plastic cylinder for a boot. Mark, you owned a Taurus, what size speaker wire did you use for the doors and how did you get it through? Thanks Mark, and for everyone else, the wire looks and feels solid as hell and has a very L-A-R-G-E diameter.

  33. Hennessy * on January 18, 2021 at 6:03 pm

    Is there a correct way to connect and amplifier and 2 subwoofers ( I don’t know much ) local shop simply splice from the rear deck speaker ? …

  34. C-J Watson on January 18, 2021 at 6:03 pm

    Such a helpful video, thank you for posting it.

  35. Daime Tosado on January 18, 2021 at 6:04 pm

    I would like to see how to do speaker rings step by step with simple tools I’m starting to install my new system and back in the day I bought everything already made now I want to it myself…….thank you for all the info I could say I’m updated now love your channel.

  41. victoor10 on January 18, 2021 at 6:11 pm

    I know one of your sponsors is knukonceptz. So can you pls answer this question. Is the kolossus fleks kable 1/0 gauge better than the NVX 1/0 gauge ?

  42. 33Megaman on January 18, 2021 at 6:12 pm

    Could you are have done a door speaker installation with the cone and without the cone witch one is the best Thank you

  43. Luis Medina on January 18, 2021 at 6:12 pm

    So I don’t need 0 gauge after a distribution block? Wouldn’t that create a bottle neck??

  44. dblr3000 on January 18, 2021 at 6:12 pm

    How about making a video about when we should use high end RCA cables and if they’re worth the money?

  45. Yasir Mahmood on January 18, 2021 at 6:14 pm

    I have 4 speaker – tweeters, 1 amplifier and 1 subwoofer in my car. I need to upgrade the wiring.
    Which is the best wring you recommend for best quality and protection (specially the guage)?
    And for my knowledge, for my above setup, will I be needing only 3 of 4 things you mentioned:
    1. One Fuse for protection.
    2. Power Wiring between Battery and Amp and for ground wiring.
    3. Amplifier to Speakers wiring.

  46. popdkem13 on January 18, 2021 at 6:14 pm

    I appreciate everything thank you

  47. COREY MFL on January 18, 2021 at 6:14 pm
