• --High-power operation can bring you wonderful in-car entertainment and listening enjoyment.
• --Light weight, convenient and easy to install. With switch, the volume can be adjusted.

Feature:
Six large capacitors, the release power is more stable.
Install:
1. Speaker connection: The amplifier board has a nice red and black wire to solder on. 4-8 ohm 100-150W woofer or full-range speakers can be used (red pickup +, black pickup - 4 ohm 8-12 inch 45-core 100-170 magnetic woofer is recommended).
2. Power connection:
A. If the car has a CD player: GND, the vehicle power supply is negative, the 12V power supply is connected to the positive pole of the car, and the REM CD player is connected to the control line (so the CD player can directly control the opening and closing of the subwoofer amplifier).
B. If the car does not have a CD player: GND is connected to the negative power supply of the car, +12V and REM are connected together, which is the positive 12V car power supply (12V can also be an indirect power supply with REM switch control amplifier switching function).
C. If it is directly connected to the battery: GND is connected to the negative pole of the battery, +12V and 12V REM, and then connected to the positive pole of the battery at the same time.

There are three places to pay attention to when installing the power amplifier:
1: To connect the power supply (+12V), you must connect the positive pole of the battery. You can’t just find a positive line on the car to connect it, otherwise the car circuit will be burned, and it will be a tragedy!
2: The GND interface must be connected to the negative pole, and it can also be grounded.
3: The middle interface of the three interfaces connected to the power line is the control line REM, start testing the machine and directly test with +12V! Then find the ACC control line interface wiring on the CD. When wiring, be careful not to touch the ground on the car. Carefully wrap the exposed parts with electrical tape, otherwise it will cause a short circuit. Burn out the machine.
