This unit is for vehicles with a 12-volt battery
and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the bat-
tery voltage.

•

To avoid shorts in the electrical system, be sure
to disconnect the ≠ battery cable before begin-
ning installation.

•

Refer to the owner’s manual for details on con-
necting the power amp and other units, then
make connections correctly.

•

Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around them where they lie against metal parts.

•

Route and secure all wiring so it cannot touch
any moving parts, such as the gear shift, hand-
brake and seat rails. Do not route wiring in
places that get hot, such as near the heater outlet.
If the insulation of the wiring melts or gets torn,
there is a danger of the wiring short-circuiting to
the vehicle body.

•

Don’t pass the yellow lead through a hole into
the engine compartment to connect to the bat-
tery. This will damage the lead insulation and
cause a very dangerous short.

•

Do not shorten any leads. If you do, the protec-
tion circuit may fail to work when it should.

•

Never feed power to other equipment by cutting
the insulation of the power supply lead of the
unit and tapping into the lead. The current capac-
ity of the lead will be exceeded, causing over-
heating.

•

When replacing fuse, be sure to only use a fuse
of the rating prescribed on the fuse holder.

•

Since a unique BPTL circuit is employed, never
wire so the speaker leads are directly grounded
or the left and right ≠ speaker leads are com-
mon.

•

If the RCA pin jack on the unit will not be used,
do not remove the caps attached to the end of the
connector.

•

Speakers connected to this unit must be high-
power with minimum rating of 50 W and imped-
ance of 4 to 8 ohms. Connecting speakers with
output and/or impedance values other than those
noted here may result in the speakers
catching fire, emitting smoke or becoming dam-
aged.

•

When connecting tweeters, please confirm the
tweeter’s usable frequency range. When you set
the cut-off frequency, set higher than the lowest
usable frequency of the tweeter.
