is on and no voltage when the unit is off.

Note: If your head unit provides preamp outputs it will have remote wire. If your

radio provides only high-level outputs, it may not have a remote wire. If you will

be using the high level outputs from your head unit, you do not need to connect

the remote output. The speaker level inputs will sense voltage on the speaker

wires and BP112 will turn itself on. If you are using only lin-level (RCA) inputs,

you must connect the remote wire to the BP112.

Input Connections:

Note: BP112 is equipped with two line level (RCA) inputs and four high level

inputs. Any combination of high-level and speaker-level inputs may be used to

provide nonfading bass when connected to a head unit with four outputs.

Head units with dedicated subwoofer outputs (line level): Connect the

subwoofer output form the head unit to line-level inputs.

Head units with four line-level (RCA) outputs:

Connect the four high-level outputs to the four high-level inputs on the BP112.

Power-Supply Connections

Positive: Connect a wire (at least 12-gauge)

between the vehicles +(positive) battery

terminal and the "+12V" connection on BP112

amplifier. You must install a fuse holder with a

50-75A fuse, within 18" of the battery. Route

the power wire through a grommet in the

vehicle's firewall. If there is not factory

grommet available, you must install one.

Negative: Connect a wire (at least 12-gauge)

between the -(ground) connection on BP112

amplifier and a bare metal surface near the

mounting location. You may need to scrape

away some paint from the metal surface to

insure a good connection. Use a screw and a

lock (star) washer.

Remote: Connect a wire (usually blue)

between the remote terminal on BP112 and

the remote output wire on the back of your

head unit (deck). This wire should provide

between +5VDC and +12VDC when the unit

TUNING BP112

BP112 provides several controls that simplify sonic integration with virtually any

vehicle's unique acoustic properties. Please read the following section carefully

to familiarize yourself with the function of each control.

Controls

Level: The Level control is a rotary knob on the panel with the electrical

connections. This switch will line match the voltage of your head unit, which will

deliver high sound quality and performance.

Bass Boost: BP112's interaction with the acoustics of your vehicle may produce

a peak or dip in BP112's response. For the vast majority of vehicles, these peaks

or dips occur at about 40Hz — around the frequency of a low bass guitar note.

Use this control to correct that peak or dip. Adjustment between –6dB and +3dB

is possible. Although response without any sharp peaks or dips is technically

correct, you may choose the position that best suits your taste.

LPF: The low-pass filter, blocks unwanted high frequencies to allow cleaner low-

frequencies.

Gain Control / Remote Gain: This control will adjust the input sensitivity of

BP112. Use this control to adjust the relative volume (loudness) of BP112 with

respect to the other speakers in the vehicle. To use the remote gain control you

must set the main gain to it's max level, then adjust the remote gain to your

preference. Note: If the main gain is not set to max then it will limit the usability of

the remote gain. Also be sure to make sure that your system is turned OFF while

executing this process, so that you do not damage your amplifier or subwoofer.

Subsonic: BP112's interaction with the acoustics of your vehicle may produce a

peak or dip in BP112's response. For the vast majority of vehicles, these peaks or

dips occur at about 40Hz — around the frequency of a low bass guitar note. Use

this control to correct that peak or dip. Adjustment between –6dB and +3dB is

possible. Although response without any sharp peaks or dips is technically

correct, you may choose the position that best suits your taste.
