    help: i got no power from this Bossv900acp. my Wife kia sorento. I have connected all wires to the metra harness and still nothing but 1 red beep from this radio.

  2. Comedian Joel Cooper on August 22, 2020 at 9:06 pm

    The wires connected by butt connectors are not meant to be pulled apart with your strength. They are used to make a connection and constant contact. There is not a wire even with your soldering that can’t be pulled apart. But who is taking the time to sit there and out of curiosity and pull their wires apart? That’s dumb. Lol.. Other than that terrible demonstration the video gave good wiring instructions.

    I have two amps, and one subwoofer, and two sets of RCA cables coming from them to be connected to my Clarion DXZ468RMP, which has 6 RCA cables, (3 sets of two), 1 set has black wires, and the other is grey wire, I think that the set with red wires are for an Aux connection, Where do I plug the RCAs from my Ground Zero GZIA2239HPX, and where do I plug the RCAs, from my Cadence Xenith? The RCAs from the radio have red and white connectors.

    Hi how do aftermarket steering wheel audio controls dodge caravan android

  21. adrianjaimes14 on August 22, 2020 at 9:20 pm

    So umm when is that much force applied to a wire on a regular day?

  22. ZerokillerOppel1 on August 22, 2020 at 9:21 pm

    The electricians at my work use heat shrink tubing which has a soldering joint built in. When they use the heat gun the 2 wire ends are automatically waterproofed and soldered at the same time. The tubing is transparent so the connection can be checked.

  23. Romila Robert on August 22, 2020 at 9:21 pm

    I like the video. Thank you for making me to understand so much. I have an question: Why in my aftermarket navigation appears 2 pink wires with tag : Key1 and Key2 ? Thank you.

    imagine finishing soldering them all up only to find out that you forgot to slip in some shrink tube.XD

  43. Juan Miguel Silva on August 22, 2020 at 9:49 pm

    Good stuff 🙂

  44. mrtrek64 on August 22, 2020 at 9:50 pm

    I’m going to be installing a BOSS Audio Systems BV9386NV in my Ford ECO 250 van. This is my first radio so please don’t laugh::) Thank you for this excellent video.
    EDIT: Nevermind…So I have to purchase an aftermarket Ford eco harness which is a female connector. After I unplug the connector from the old radio I then plug it right into my female aftermarket harness. Match my wires with the harness for my new radio and then solder or crimp and then plug into my new radio. As you showed the soldering can be done on a bence and not in the car.

  45. Zack Benefiel on August 22, 2020 at 9:52 pm

    Hey I have a 2000 jeep cherokee sport can u help explain my harness forme colors and uses plz

  47. itolond on August 22, 2020 at 9:56 pm

    Mate – I am building a new loom on custom build car (no data bus) – I have no head unit yet but leaning to double din apple play pioneer unit. the AMp is a MB Quart NA540.6 Nautic Amplifier, 6-Channel 540-Watt and I have run RCA cables to the dash area. I also have DKMUS Universal ISO Car Radio Wire Cable Wiring Harness Stereo Adapter Connectors. What to best practice here, do splice in th e RCA to the ISO connector, get adaptors or should use the loom plugs with the head unit? ( was hoping to get wires sorted and then choose a head unit)
