Volt/Ohm Meter
Wire strippers
Wire crimpers
Wire cutters
#2 Phillips screwdriver
Battery post wrench

1/8" diameter heatshrink tubing
Assorted connectors
Adequate Length—Red 1/0 AWGPower Wire
Adequate Length—Remote Turn-on Wire
Adequate Length—Black 1/0 AWG Grounding Wire
11. RCA Input Jacks – These pro-audio panel mount RCA jacks provide an easy connection for signal level
input.They are nickel-plated to resist the signal degradation caused by corrosion.Their design reduces the
stress created to internal boards when RCA cables are connected or disconnected.
12. Infrasonic Filter – A 28Hz High Pass filter designed to prevent frequencies below the audio range
from being applied to the subwoofer from the amplifier. Consequently improving subwoofer
performance and power handling, particularly in vented enclosures.
13. Gain Control – The input gain control is preset to match the output of most source units. It can be
adjusted to match output levels from a variety of source units.
14. Variable Crossover – Is a built-in 24dB/octave Butterworth filter with a crossover point variable
from 35Hz to 250Hz.The crossover is set to Low-Pass (LP).
15. Mode Switch – Used to set the amplifier between single, for single amplifier use, and Master or Slave
for when connecting multiple bd amplifiers together.The first amplifier in the series being set as
Master and the subsequent amplifiers being set as Slave.This allows one gain, crossover, infrasonic
filter and bass boost setting for all slaved amplifiers.
NOTE:
Gain on the Slave amplifier allows for fine tuning adjustment.
16. Phase Switch – Used when bridging two bd amplifiers together using a bd Sync cable to phase one
amplifier 180° from the other when driving a common load.
17. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-chaining an additional
amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier
location.
18. Remote Terminal – This heavy duty, nickel-plated wire connector will accept wire sizes from
8 AWG to 16 AWG.This terminal is used to remotely turn-on and turn-off the amplifier when
+12V DC is applied.
19. Power Terminals – The power and ground connectors on the amplifier are nickel-plated and will
accommodate up to 1/0 AWG wire maximizing the input current capability of the amplifier.
