INSTALLATION

Disconnect negative battery terminal
Place terminal in a secure position so that it won’t accidentally contact the negative battery post
Run Cables
Properly route power, speaker and RCA cables through the vehicle.
Mount Amplifier
Choose a mounting location that will provide adequate air ventilation. Mount the amplifier to a secure surface. Do not mount the amplifier upside down.
Chassis Ground
The chassis ground connection is critical to the performance of the amplifier. Choose a location that is close to the amplifier. Completely scrape away the paint and use a nut and bolt if possible. DO NOT USE AN EXISTING FACTORY BOLT!
Negative Power Connection
Attach the chassis ground cable to the amplifier negative terminal. It is important to make sure this connection is very tight.
Remote Turn-on Connection
Attach the remote tur on wire to the amplifier remote output of the source unit
Positive Power Connection
Attach the main power cable to the amplifier +12V. The cable must run directly to the battery and be properly fused and be very tight.
Signal Input Connection
Connect the RCA cables to the INPUT connectors.
Level Control
Tum the LEVEL control completely counter-clockwise to minimum.
Speaker Connections
Using spade terminals, connect the speaker cables (o the speaker output connectors. Follow the diagram below that best fits your speaker configuration.
Positive Battery Connection
Connect the power cable to the positive battery terminal. The power cable must be fused within 18 inches of the battery Lerma. Be prepared to disarm your vehicle’s alarm and to enter your radio / source unit code.
Re-connect Negative Battery Terminal
Re-connect the negative battery terminal making sure it is securely tightened

SETUP

(A] Mode
Switch to route input signal stores pective amplifier channels. (B) Crossover
To set up the crossover for the required use of the amplifier.
LPF(8P)-Only |ow frequencies will be reproduced with subsonic filter FULL- Entire frequency range will be reproduced.
HPF-Only mid/high frequencies will be reproduced.

(C)High pass Adjustment
High frequency HPF filter FRONT. The regulator can change the frequency of the high frequency filter.
X1/X20 – factor conversion switch. It allows for an X20 fold increase in shear on the high frequency filter. In the X1 mode, the filtering ~ range is 12HZ- 250Hz.In X20 mode, it is 250Hz 10 5000Hz. (D] Low pass Adjustment

Low frequency LPF filter FRONT. The regulator can change the frequency of the low-frequency filter,
X1/X10 – factor conversion switch. It allows for an X10 fold increase in shear on the low frequency filter. In the X1 mode, the filtering range is 50Hz to 500Hz.In X10 mode, it is 500Hz to 5000Hz

(E) Bass Boost
The BASS BOOST or BASS EQ control will increase the output at 45Hz for more pronounced bass. Exercise caution.
Increase the level in small amounts unti distortion is noticed, then back off alible.

(F) Subsonic
This controller allows you to filter low frequencies in a range between 10Hz and 50Hz. This function reduces the mechanical Xmax and raises the Capacity of the connected subwoofer.

(G) High Input
Head units without RCA pre-amplifier output signal, can be connected using the high-level input to connect the speaker output of the head unit directly. If used, the amplifier turns on automatically (auto-on feature). The remote input of the power supply terminal remains unused Important note: light-level and RCA inputs should never be used simultaneously! This may cause serious damage to the amplifier.

(H) Remote Level Control
Some models include a bass remote. Avoid adjusting the bass remote while operating vehicle.

(I) Master & Slave Wiring
Strapping TWO $2-A2200.1 Amplifiers When Strapping two $2-A2200.1 amplifiers, the minimum speaker Impedance is 2ohms:

(J)Level Setting
This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit.
THIS IS NOT A VOLUME CONTROL!

If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).
Tum on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or *0″ adjustment. Make sure that the green LED on
the end of the amplifier is illuminated.
Playa clean musical selection of which you are very familiar. CD is preferred Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.
Increase the amplifier level (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.

CONNECTION METHODS

The minimum permissible load impedance at the output of the amplifier is 2 ohm for full rang amp and 1 ohm for mono-block amp. Use these formulas to aciculate the load impedance of various types of connections
SUBWOOFERS WIRING DIAGRAMS
Serial connection
Total impedance = Sub 1+ QSub2+ QSub3…
Parallel connection
SCHEMES OF ENABLING THE LOAD OF THE SUBWOOFER
In any case do not expose the amplifier to the loads lower than specified by the manufacturer. Use these schematics to calculate load impedance of different connection types.
Voice coils 1+1, 2+2, 4+4 Ohm The subwoofer has voice coil D1, D2 or D4.
