01

INPUT

Connect RCA output cables from the headunit to
EUPHORIA XPERT amplifiers’ RCA Input

GAIN (6V ~ 0.2V)

Matching the output voltage of the headunit‘s RCA
line-outs to EUPHORIA XPERT amplifiers’ input section.

HIGH PASS FILTER

Controls the High Pass Crossover point for the speaker
outputs.

LOW PASS FILTER

Controls the Low Pass Crossover point for the speaker
outputs.

+12V (POWER CONNECTION)

This must be connected to the fuse positive terminal
(+12V) of the battery.
Recommended wire is 4 gauge or thicker.
Check the battery voltage.

GND (GROUND CONNECTION)

It is connected to the negative or ground cables of
the vehicle.
Recommended wire is 4 gauge or thicker.

REM (REMOTE)

It is connected to switched +12V with a trigger cable
coming from the head unit.

SPEAKER OUTPUTS

It connects amplifier’s terminal to subwoofer
speakers or full range speakers.
Minimum speaker wire is 12 gauge

POWER & PROTECTION INDICATOR

Power LED - Green-lit shows normal operation.
Protect LED - RED-lit shows general malfunction,
faulty connection or thermal protection.

3. INSTALLATION

In case you install the amplifier by yourself, please read owner’s manual very carefully before your installation
Please take all steps into consideration or, you can have DB Drive or DB Research’s authorized dealer to check
installation and set your car audio systems.

3-1. MOUNTING PREPARATION

Disconnect the negative ( - ) battery cable before mounting your amplifier or making any connections. Check
the battery and alternator ground ( - ) connections. Make sure they are properly connected and free of
corrosion before selecting a mounting location. Please take some concerns into consideration with cooling
efficiency and safety.

3-2. MOUNTING PREPARATION

The EX4 amplifier uses a specially designed heat radiation heatsink to avoid excessive heat from circuitry.
But for better heat dissipation, it is good to find the mounting location where you can install
vertically with the heatsink fins and better air flow around heatsink.
For the safety, You have to find a dry and well ventilated location and make sure any cables and drilling car
equipment are not interfere with mounting location. Be sure the mounting location and drilling of pilot cables
will not present a harzard to any cables, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle
systems or components.

3-3. +12V, GND, REM CONNECTION.

12V ( POWER CONNECTION )

Before mounting amplifier, disconnect the negative ( - ) wire from battery to protect any accidential damage to

m. EK4 amplifier requires at least the use of 4 gauge wiring for all power connections.

Connect the power cables to power terminal labeled as +12V. EX4 Amplifier is not internally fused and
require external fusing.

In order to install external fuses, connect one end of fuse holder to the power cable and the other end of
fuse holder to positive battery within 18in of the same cable gauge. This fuse location will protect the system
and the vehicle against the possibility of a short circuit in the power cable.
Be sure to use fuses and fuse holders adequate for the current draw application.
