Connect stripped ends of the red/black speaker wire from the amplifier's
BASS
output to the
corresponding spring loaded terminals on the Dayton Audio DCS165-4 6-1/2" Classic Subwoofer. Place
driver in opening and secure in place using 8 x #8 x 3/4" Deep Thread Pan Head Screws being careful
not to strip out the holes (a power drill is not recommended).

Prepare the passive radiator by removing the screw in the center of the mass plug on the back of
the passive radiator. Add 4 X 1-1/2" fender washers to the screw and replace in the back of the radiator.
Secure tightly in place. The added mass on the radiator can be adjusted to your preference.
Tip:
Less
mass will have more punch to the bass response in the 50 to 70 Hz range, but sacrifice lower
frequencies. More mass can extend the bass response with less output in the 50 to 80 Hz range. We find
that 4 washers is the best compromise.

Finally, place the passive radiator in the opening in the back of the enclosure and secure in place
using 5 x #6 x 3/4" Deep Thread Pan Head Screws being careful not to strip out the holes (a power drill
is not recommended).
36)
Plug the 15 VDC 4A AC Adapter Power Supply into the DC jack on the back of the enclosure
allow a full 24 hours for the initial charge. Tip: The initial charge can be done before installing the
battery charger board by plugging the power supply directly into the battery charger board.
