INSTALLATION
1. PLAN THE INSTALLATION
Before you go any further with the installation of the amplifier, map out the system
and the necessary wiring. Your work will be simplified if you have a plan of
attack. Consider all electrical requirements, as well as physical, such as amplifier
ventilation and availability of space.
2. SELECT OPERATING MODES (on underside)
The configuration switches are accessible by removing the plugs on the
underside of the amplifier. They allow you to determine the operating
configuration of the amplifier, including:
5 or 3 channels of input (via bridging)
normal (High Power) or low impedance (High Current) operation with the
subwoofer channel
number of channels of input to drive the amplifier
crossover activation for the subwoofer, front, and rear channels
A. Stereo/Bridged Mono (see System Diagrams #1 - 4)
Each pair of the 4 channels rated at 25 watts each (12 volts) can be bridged
mono. If running either pair of channels in mono, be sure to set the switch for the
appropriate pair to "mono."

Crossover Settings
Each pair of the 4 channels rated at 25 watts each (12 volts) can be set to
operate either full range or high pass. To use the built-in high pass
crossover, select high pass. If you are using the mono channel full range or
with an external crossover, select bypass.
STEREO

The mono channel can be set to operate either full range or low pass. To
use the low pass crossover, select low pass; to operate the channel up to
400 Hz (for use with an external crossover), select bypass.
C. High Power/High Current (mono channel)
The mono channel can be set to operate in either high power or high current
mode. Select the mode of operation as follows:
1 Ohm or higher
less than 1 Ohm
The REFERENCE405 subwoofer channel is designed to drive extremely low
impedances. Be sure that the High Power/High Current switch is in the
appropriate setting for best performance and maximum reliability.
D. Inputs (see System Diagrams #I - 4)
All five channels of the REFERENCE405 can be driven with 2,4, or 6 channels of
input. If your head unit has one or two pairs of outputs, you can drive all 5
channels of the amplifier.

NOTE: Channels I & 2 are not listed. These channels must a/ways receive input
in order for operation of all 5 channels.
3. LOCATION OF THE AMPLIFIER
When mounting the amplifier, it should be securely mounted to either a panel in
the vehicle or an amp board or rack that is securely mounted to the vehicle. The
mounting location should be either in the passenger compartment or in the trunk
of the vehicle, away from moisture, stray or moving objects, and major electrical
components (electric motors, fuel pumps, etc.). To provide adequate ventilation,
mount the amplifier so there are at least 2 inches of freely circulating air above
and to the sides of it.
4. MOUNTING OF THE AMPLIFIER
1. Using the amplifier as a template, mark the mounting surface.
2. Remove the amplifier and drill the holes.
3. Mount the amplifier to the surface using the provided hardware.

Untuk speaker pintu 4+subwoofer 1 Diagram pemasangan nya gimana ?
To install the Soundstream Reference 405 amplifier with 4 door speakers and 1 subwoofer, follow these steps:
1. Power and Ground Wiring:
- Use high-quality, low-loss power and ground cables.
- Connect a 4-gauge power cable from the battery to the amplifier.
- Ground the amplifier securely to the vehicle chassis.
2. Speaker Wiring:
- Channels 1 and 2: Connect to the front door speakers.
- Channels 3 and 4: Connect to the rear door speakers.
- Channel 5 (subwoofer channel): Connect to the subwoofer.
3. Speaker Output Mode Selection:
- Ensure channels 1-4 are set to operate in stereo mode for full-range sound.
- Set the subwoofer channel to low-pass mode.
4. Bass Control and Frequency Adjustment:
- Use the Hawkins Bass Control to tailor the subwoofer response.
- Adjust the frequency and boost settings as needed.
5. Testing and Final Adjustments:
- Play test audio and adjust gain levels for balanced output.
- Fine-tune crossover settings to match speaker specifications.
- Ensure all connections are secure and free of distortion.
This setup ensures optimal performance from the Reference 405 with 4 door speakers and a subwoofer.
