INTRODUCTION
Power Acoustik amplifiers provide high-performance sound reinforcement for your
mobile audio equipment. Its versatility enables compatibility with optional Equalizers,
Frequency Dividing Crossover Networks, and other audio processors in a customized
system. The Multi-Mode bridging capabilities allow flexibility in hosting several different
speaker configurations.
To achieve optimum performance, it is highly recommended that you read this
Owners Manual before beginning installation.
WARNING
High powered audio systems in a vehicle are capable of generating "Live Concert"
high levels of sound pressure. Continued exposure to excessively high volume sound
levels may cause hearing loss or damage. Also, operation of a motor vehicle while
listening to audio equipment at high volume levels may impair your ability to hear
external sounds such as; horns, warning signals, or emergency vehicles, thus
contributing to a potential traffic hazard. In the interest of safety, Power Acoustik
recommends listening at lower volume levels while driving.

Before beginning the installation, consider the following:
1. Do you plan to add additional mobile electronics equipment in the future?
If you plan to expand your system by adding other components sometime in the
future, ensure adequate space is left and cooling requirements are met.
2. Should you use high or low level inputs?
Your Amplifier has been designed to accept Low-Level(Pre-Amp outputs from your
radio) source signal. If your radio/source is equipped with Pre-Amp outputs, it is
possible to utilize them to drive the Amplifier and the 2 front speakers. Then, use the
built-in power of your radio to drive the 2 rear speakers.
3. Are your components matched?
The RMS power rating of your speaker(s) must be equal or greater than the RMS
power rating of your amplifier. Your speaker(s) also must be 2 - 8 Ohms impedance
for stable amplifier operation. Impedance information is normally printed on the
speaker basket or magnet.
4. Where will the amplifier be installed?
Consider both the length of your leads, and routing when determining the mounting
location. It is best to run power and RCA wiring on opposite sides of the vehicle to
prevent induced noise. Pre-amp input jacks require a length of high quality shielded
male to male RCA patch cord.

CONNECTING THE POWER (Fig.1,2)
CAUTION:
AS A PRECAUTION, DISCONNECT THE POWER WIRE FROM THE BATTERY WHILE MAKING THE
POWER AND GROUND CONNECTIONS TO THE AMPLIFIER.
4/8 GAUGE(Thicker if planning for additional Amplifiers) wire is recommended for
both the power and ground wires. 12 Gauge, for the remote turn-on wire. Both
types are available at most Mobile Audio Dealers or Installation Shop.
(1) Ground :To Vehicle Chassis
To avoid unwanted ignition noise caused by ground loop, it is essential that the
Amplifier be grounded to a clean, bare, metal surface of the vehicle's Chassis
NOTE :
GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT. (1 METER).
(2) +12 Volt(Fused) Constant Power:To Battery (+)
Due to the power requirements of the Amplifier, this connection should be made
directly to the positive (+) terminal of battery. For safety measures, install an in-line
Fuse Holder (not included) as close to the battery positive (+) terminal as
possible with an ampere rating; not to exceed total value of fuses in Amp.
(3) Remote Turn-On Input: To remote turn-on output of Car Stereo
This Amplifier is turned "ON" remotely when the vehicle's stereo is turned "ON".
NOTE :
IF YOUR RADIO DOES NOT HAVE A +12 VOLT OUTPUT LEAD WHEN THE RADIO IS TURNED ON, THE "REMOTE"
TERMINAL ON THE AMPLIFIER CAN BE CONNECTED TO VEHICLE'S ACCESSORY CIRCUIT THAT IS LIVE WHEN THE
KEY IS "ON".

CONTROL FUNCTIONS
1. RCA input jacks
These RCA input jacks are for use with source units that have RCA or Line level
outputs. A source unit with a minimum level of 200mV is required for proper operation.
The use of high quality twisted pair cables is recommended to decrease the possibility
of radiated noise entering the system.
2. GAIN Control
The level control will match the amplifiers sensitivity to the source units signal voltage.
The Operating range is 200mV minimum to 6V maximum.
CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be
damaged.
3. Full pass x-over switch
When the switch is in the "Full" position, the full range is bypassed.
4. Low pass x-over switch
When the switch is in the "LPF" position, frequencies lower than the low pass frequency
setting are passed.
4.1 Low pass x-over frequency control
This control is used to select the desired low pass x-over frequency.
BAMF800/2, 1250/2, 1800/2, 2200/2, 2600/2, 1200/4, 1600/4 : The frequency can be
adjusted between 30Hz and 250Hz.
BAMF2000/1D, 4000/1D, 55001D : The frequency can be adjusted between 40Hz and
200Hz.
5. High pass x-over switch
When the switch is in the "HPF" position, frequencies higher than the high pass
frequency setting are passed.
5.1 High pass x-over frequency control
This control is used to select the desired high pass x-over frequency.
BAMF800/2, 1250/2, 1800/2, 2200/2, 2600/2, 1200/4, 1600/4 : The frequency can be
adjusted between 50Hz and 500Hz.
6.Bass EQ
BAMF800/2, 1250/2, 1800/2, 2200/2, 2600/2, 1200/4, 1600/4 : The boost can be
adjusted between 0dB to12dB.
BAMF2000/1D, 4000/1D, 55001D : The boost can be adjusted between 0dB to 18dB.
7. Auxiliary outputs
The Auxiliary outputs offer Power Acoustik amplifiers easy, unlimited system expansion.
Route RCA's from the line out of the first amplifier to the line input of a second
amplifier when using a single source output.

CONTROL FUNCTIONS
8. SUBSONIC
BAMF1250/2, 1800/2, 22200/2, 2600/2 : The frequency can be adjusted between 15Hz
and 50Hz.
BAMF2000/1D, 4000/1D, 5500/1D : The frequency can be adjusted between 20Hz and
50Hz.
9. REMOTE
Controls the subwoofer amplifier gain, from a remote location for ease of adjustment
during listening.
Warning: Do not connect a level control knob from other manufacturers to the Remote Sub Level
Control of any amplifier. Even though the connectors fit properly, the control knob and connector
pin positions may be different and the amplifier will be damaged.
10. PHASE
0°or180° selectable for switching the phase of the output to the woofer.
11. MASTER/SLAVE MODE[BAMF2000/1D, 4000/1D, 5500/1D]
Controls whether the amplifier is a slave or master when connected in combined
amplifier configurations. (Refer to the Master Mode section of this guide.)
All of the controls will be adjusted by the "Master" amplifier.
-Slave mode : To be switched " Slave mode" when linking one amplifier with another
amplifier.
-Master mode : To be switched " Master mode" when only using this single amplifier.
12. INPUT MODE
Selects 2, 3 or 4 channel operation(FIG. 1)
13. GND
Connect this terminal directly to the sheet metal chassis of the vehicle, using the
shortest wire necessary to make this connection. Always use wire of the same gauge
or larger than the (+)12 volt power wire. The chassis connection point should be
scraped free of paint and dirt. Use only quality crimped and/or soldered connectors
at both ends of this wire.
Warning : Do not connect this terminal directly to the vehicle battery ground terminal or any other
factory ground points.
14. Remote Turn On
This terminal turns on the amplifier when (+)12 volt is applied to it. Connect it to the
remote turn on lead of the head unit or signal source.
15. (+)12 Volt Power
Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of
the vehicle battery or the positive terminal of an isolated audio system battery.
Warning: Always protect this power wire by installing a fuse or circuit breaker of the appropriate
size within 12 inches of the battery terminal connection.
