Important Safety Instructions
2
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.
8. Do not install near any heat sources such as muers, silencers, exhaust
pipes, or other apparatus (including ampliers) that produce heat.
9. WARNING: Improper installation may lead to permanent injury or death.
Installation of the apparatus must be done with great care by qualied
personnel, to prevent damage to fuel lines, power and other electrical
wiring, hydraulic brake lines, and other systems, that might compromise
vehicle safety.
10. Provide +12V and Ground wiring of sucient size to ensure adequate
current to the amplier. For the LC-1.1500 this means 0 to 2 gauge wire.
11. Use rubber grommets to protect wiring whenever passing wires through
metal openings or bulkheads.
12. Only use attachments/accessories specied by the manufacturer.
13. Refer all servicing to qualied service personnel. Servicing is required
when the apparatus has been damaged in any way, such as the power input terminals are damaged, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
14. This apparatus shall not be exposed to dripping or splashing, and no
object lled with liquids, shall be placed on the apparatus.
15. Fuses shall be replaced only with the correct type and fuse value, and
only when the apparatus is powered o.
16. Exposure to high sound pressure levels may lead to permanent hearing
loss. Take every precaution to protect your hearing.
The lightning ash with arrowhead symbol within an equilateral
triangle is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure, that may be of
sucient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to
alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
Caution: to reduce the risk of electric shock, do
not disassemble the apparatus, other than to
remove the top panel to access the controls.
There are no user-serviceable parts inside. Refer
servicing to qualied personnel.
Recycling notice: If the time comes and this apparatus has fullled
its destiny, do not throw it out into the trash. It has to be carefully
recycled for the good of mankind, by a facility specially equipped
for the safe recycling of electronic apparatii. Please contact your
local or state recycling leaders for assistance in locating a suitable
nearby recycling facility. Or, contact us and we might be able to
repair it for you.

1. Fuses 40A – Replace the fuses only with the exact same style
and Ampere rating. Disconnect 12V power before changing or
inspecting the fuses.
2. Power Input Terminal +12V – This screw terminal connects to
the +12V battery binding post of the vehicle. Use quality insulated
wiring of the recommended wire gauge, such as wire gauge 2 or
thicker. Thinner wire may cause an overheating hazard due to the
large currents involved.
3. Remote Power Input Terminal – This screw terminal connects
to the 12V remote trigger output of some head units. When the
head unit is turned on, then the LC-1.1500 amplier will turn on.
Alternatively, you can use the GTO feature of the amplier so it
will turn on when an audio signal is detected at the speaker-level
or line-level inputs.

4. Power Input Terminal Ground – This screw terminal connects to
a good ground connection on the vehicle.
5. Speaker-Level Inputs – The LC-1.1500 amplier is supplied with
a standard 4-conductor plug that allows for easy installation and
removal. The speaker-level output from ampliers and factory
installed radios can connect here, so the LC-1.1500 will receive
the audio signals and do its subwoofer thing. The left and right
audio signals are summed internally to produce a mono subwoofer signal. Make sure that you follow the plus and minus polarity
markings on the LC-1.1500 and match it to the polarity of the
speaker wiring. Do not use the RCA Line-level inputs if you are
using the speaker-level inputs.

6. RCA Analog Line-Level Inputs – The line-level output from the
head unit or factory installed radios can connect here, so the
LC-1.1500 will receive the line-level audio signals. The left and
right signals are summed internally to produce a mono subwoofer
signal. Do not use the speaker-level inputs if you are using the
RCA line-level inputs.
7. Remote Control Connector – This connects to the optional ACR-1
remote control and allows you to remotely control the output
level.
8. Speaker-Level Output Terminals – These screw terminals connect with speaker wire to the subwoofer, or multiple subwoofers.
Make sure that the average combined speaker impedance does
not dip below 2 Ohm. The LC-1.1500 has four connections (2 plus
and 2 minus).
