What you need: Rotary cutting tool, hand tools and installation time for modifying the soundbar. MB Quart’s service bulletin warns that the original connector can supply only low frequencies. A 3.5-inch-connector adapter may be needed; a summing interface and amplifier are recommended for full-range performance. Confirm included harness revision before installation.
