Reconnect the amplifier connector to the amplifier.
Connect the white two-pin connector of the adaptor harness to the white two-pin connector of the
subwoofer harness.
There are two lower subwoofer brackets provided depending on the wheelbase of the vehicle. For
Tahoe/Yukon use the longer bracket. For Suburban/Yukon XL use the shorter bracket. Determine the
lower subwoofer bracket needed and attach it to the subwoofer using the supplied nut and bolt as shown
in Fig 22
Note: The lower subwoofer bracket should overlap the bracket attached to the
subwoofer as shown. The nut should be installed on the side closest to the
subwoofer. Leave the nut and bolt slightly loose so the lower bracket can
slide.
Remove the nut that secures the jack bracket indicated in Fig 23
Pull the factory wire harness slightly away from the metal in order for the subwoofer upper bracket to pass
under the factory wire harness. Fig 24
Hold the subwoofer at about a 45 degree angle and slide the lower subwoofer bracket over the jack stud.
