hi There, greetings to Denmark!
No, only in Offer with Soundsystem Pro you got the Wires (and of course the Sub
). In normal System the Speakers are amped from the Headunit. In Soundsystem Pro the Speakers are amped by the Amplifier in the Subwoofer!
There are 2 different Wiring-Kits. You can order the whole wiring Kit for Soundsystem Pro with Sub by your Fiat-Dealer.
My Meanings are that ist too expensive and too much work on this little extra Sub.
