Bass Boost Frequency Control
You can select a bass boost frequency from 40 to 120 Hz with the bass boost control.
Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound
Cut Off Frequency Control for LPF
You can select a cut off frequency from 40 to 240 Hz.
CAUTION
•Disconnect the negative (–) terminal of the battery to avoid the risk of short-circuit and damage to the unit.
•Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around it where they lie against metal parts.
•Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body.
•Make sure that wires will not interfere with mov- ing parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism.
•Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. The current capacity of the wire will be exceeded, causing overheating.
•Never replace the fuse with one of greater value or rating than the original fuse. Use of an improp- er fuse could result in overheating and smoke and could cause damage to the product and injury including burns.

Battery
Ground wire (sold separately)
The ground wires must be same size as the battery wire.
Connect to metal body or chassis.
Battery wire (sold separately) For the wire size, see the “Connecting the Power Terminal” section. The battery wire, the ground wire and the optional direct ground wire must be same size.
After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery.

MODE SELECT Switch
You can select amplifier’s sync mode from MASTER, SYNC and SYNC INV. For the position of the MODE SELECT switch, see the “Connecting the Speaker Wires” section.
Power Indicator
The power indicator lights when the power is switched on.
• This unit is for vehicles with a 12-volt battery and |
negative grounding. Before installing it in a recre- |
ational vehicle, truck or bus, check the battery |
voltage. |
• If the car stereo is kept on for a long time while |
the engine is at rest or idling, the battery may go |
dead. Turn the car stereo off when the engine is at |
rest or idling. |
• If the system remote control wire of the amplifier |
is connected to the power terminal through the |
ignition switch (12 V DC), the amplifier will |
always be on when the ignition is on— regardless |
of whether the car stereo is on or off. Because of |
this, the battery could go dead if the engine is at |
rest or idling. |
• DO NOT connect a subwoofer with a lower |
impedance than specified in the “Connecting the |
Unit” section. Amplifier damage, smoke, and |
input and an impedance 4 Ω, or 2: a subwoofer |
with a 1,000 W or larger nominal input and an |
impedance 2 Ω. If the nominal input and imped- |
ance are out of the above ranges, the subwoofer |
may catch fire, emit smoke or become damaged. |
• Install and route the separately sold battery wire |
as far away as possible from the speaker wires. |
Install and route the separately sold battery wire, |
ground wire, speaker wires and the amplifier as |
far away as possible from the antenna, antenna |
cable and tuner. |
• Cords for this product and those for other prod- |
ucts may be different colors even if they have the |
same function. When connecting this product to |
another product, refer to the supplied Installation |
manuals of both products and connect cords that |
have the same function. |
Optional direct ground wire (sold separately) When chassis ground- ing is not sufficient, direct grounding should be used. The wire size should be same size as the bat- tery wire.

Bass Boost Level Control
Bass boost level control can boost the level around the frequency selected by the bass boost frequency control from 0 to 12 dB.
Subsonic Select Switch
The subsonic filter cuts inaudible fre- quencies below 20 Hz to eliminate unwanted vibrations and minimize power loss.
overheating could result from a non-specified con- |
nection. The amplifier surface could also become |
hot to the touch and minor burns could result. |

System remote control wire (sold separately)
Connect the male terminal of this wire to the system remote control termi- nal of the car stereo (SYSTEM REMOTE CONTROL). The female termi- nal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male ter- minal to the power terminal through the ignition switch.
