D800
Please read manual carefully before installation

Thank you for purchasing and using Rebec products. In order to prevent damage to the device and possible injury,
please read this manual carefully and follow all installation steps, so that you can be familiar with each control and
function of the amplifier, and can maximize the performance and characteristics of the amplifier, so Rebec products can
bring you a pleasant listening experience.
This product has been checked for quality before shipment. In order to obtain proper performance and ensure a
comprehensive warranty, it is strongly recommended that the installation of this product be provided by an authorized
Rebec dealer.
installation tips:
• It is forbidden to disassemble and modify the product by yourself. Disassembly and modification of the product by
yourself may cause accidents, fire or electric issues.
• This product is recommended for use in an automotive environment with a DC voltage range of 12-14.4V. If this voltage
range is exceeded, the product may malfunction. • It is recommended to install the power supply and RCA at a distance of
at least 20cm apart from the electronic equipment on the vehicle during the installation process to prevent signal
interference. • Before wiring, be sure to disconnect the cable from the negative battery terminal, otherwise it may cause a
short circuit and cause a fire.
• Do not use the screws and nuts in the brake system during installation and grounding, otherwise the brake system will
fail and cause traffic accidents. • When there is no sound, smoke, etc., please stop using it immediately and contact the
Rebec dealer in your city.
• Protect the cable to prevent damage caused by pulling or cutting and short circuit.
• The volume should be adjusted within the zero limit of distortion.
• In order to get a safe, professional and reliable installation, please hand over the product to the modified service shop
authorized by Rebec and let them install it for you. Warning:
The powerful car audio system can create extremely high sound pressure, similar to the level of real live concerts.
Prolonged exposure to excessive sound pressure may cause hearing loss or loss of hearing. In addition, when you listen
to audio equipment at high volume, driving a car may reduce your attention to road traffic and the intensity of listening to
external sounds, such as horns, warning signals, or emergency vehicles. For the sake of the overall situation and your
own safety, it is recommended to listen to music at an appropriate low volume while driving.

Connector and control unit
① Power terminals
GND Connect to car chassis or battery negative terminal，
REM Connect the amp turn wire on from source
+12V Connect to the positive terminal of the battery. (Remember. Use propriate fuse)
② Speaker terminal ㊀to minus terminal on woofer，㊉ to positive terminal on woofer
③ Adjustment knobs
LOW PASS deside highest frequensy played by amp，SUBSONIC deside lowest frequensu played by amp
BASS BOOSTlevel of bass boost，GAIN INPUT level of amplification, must be matched to source
④ RCA inn and output for bridge mode/ RCA L and R input from source
⑤ N/A
⑥ Status indicators
The blue light is normal, and the red light is protection. If the red light is on, the amplifier may be
overloaded or work abnormally. Stop using it immediately.
note
The subsonic filter (SUBSONIC) is off by default. If you want to use this function, you need to remove the
upper cover of the amplifier and connect the pin to the on state. The schematic diagram is as follows
After removing the upper cover, you can see the words On / Off on the circuit board. The default connection
is Figure a; when using this function, connect the pins to the two pins on the left, as shown in Figure b.
