source unit with a minimum output of 200mV is required for proper operation. However, this input
will accept levels up to 6Vrms.
12. LINE OUT (RCA) Jacks
RCA style output jacks allow for a signal to be sent to other amplifiers in a daisy-chain configuration.
Only one Remote Bass Control can be used when multiple bass amplifiers are connected.
13. +BATT (Power Input Connection)
This terminal is the main power input for the amplifier and must be connected directly to the positive
(+) terminal of the car battery.
14. GND (Ground Input Connection)
A good quality ground is required for your
X-Treme
D Class amplifier to operate at peak
performance. A short length of cable the same gauge as your power cable should be used to
attach the ground terminal directly to the chassis of the vehicle. cable.
15. REMOTE (Remote Input Connection)
All Xtreme amplifiers can be turned on by applying 12 Volts to this terminal. This can be found on
the rear of the source unit in the form of an electric antenna output, or a remote output. If this is
not available you can wire to the ACC position on the key. A 1 mm2 wire is sufficient to run the
REMOTE.
16. SPEAKER Terminals
As shown in the wiring diagrams, be sure to observe speaker polarity through the system and
speaker impedance. This specially tooled terminal is designed to accommodate up to 8 gauge
speaker wire.
CAUTION :
Do Not Bridge the speaker outputs on these D Class models, this is already a Mono output!
WIRING AND CONNECTIONS
***
WARNING
***
Disconnect the negative (-) battery terminal before you start any wiring work! The power
supply of your car audio system must be disconnected until the entire wiring installation
is completed.
Your
X-Treme
D Class amp will draw large levels of current, so use the largest gauge
power/ground cable as possible. Using too small of power cable can result in unnecessary over-
heating of the amplifier, distortion at high volume levels and might even cause the thermal
protection circuitry to shut-off the amplifier.
