    Car: VW Transporter - <2004

    Iv just bought this didt look to see if wires were included looks like there not right?. So will need to buy speaker wires and amp wiring separately yeah?
    Thanks Marion

    Answer: 
    hi,

    this would require an amplifier and a wiring kit as it doesnt come with those, we would recommend something like the JWTRU81 for the speaker wires.
