Remote Juice Control (B2.350.1 Only); Using Passive Crossovers - Lightning Audio Bolt B2.150.2 User Manual

REMOTE JUICE CONTROL (B2.350.1 Only)

Mounting and installation
1. Find a location, either under the dash or near
the center console, that gives easy access to
the remote.
2. Using the screws supplied, install the remote.
3. Route the cable for the remote and connect to
both the remote and amplifier.

USING PASSIVE CROSSOVERS

A passive crossover is a circuit that
uses capacitors and/or coils and is
placed on speaker leads between the
amplifier and speaker. The crossover
delegates a specific range of
frequencies to the speaker for
optimum driver performance. A
crossover network can perform one of
three functions: High-Pass
(capacitors), Low-Pass (inductors or
coils) and Bandpass (combination of
capacitor and coil).
The most commonly used passive
crossover networks are 6dB/octave
systems. These are easy to construct
and require one component per filter.
Placing this filter in series with the
circuit will reduce power to the
speaker by 6dB/octave above or
below the crossover point depending
on whether it is a high-pass or low-
pass filter. More complex systems
such as 12dB/octave or 18dB/octave
can cause impedance problems if not
professionally designed.
Passive crossovers are directly
dependent upon the speaker's
impedance and component value for
accuracy. When passive crossover
components are used in multiple
speaker systems, the crossover's
effect on the overall impedance should
be taken into consideration along with
the speaker's impedance when
determining amplifier loads.
