Quick Start
1. It only takes a few steps to get your LC-1.1500 amplifier up and
running!
2. Undo the +12V and Ground connections to the car battery
before making any connections to the amplifier.
3. When making connections, designate red RCA plugs as right,
and designate white, black, or grey plugs as left. This is a good
idea for all signal connections made in your audio system. The
key is consistency. Stick with the same color coding and you’ll
reduce possible problems.
4. Use quality interconnect cables. We know from experience that
really cheap cables can cause a multitude of problems. They
tend to break inside or corrode, causing a loss of signal or hum.
They also have poor shielding.
5. Connect the +12V input terminal of the unit to the +12V termi-
nal of the vehicle battery. Use 2 gauge insulated wire or thicker.
6. Connect the Ground terminal of the unit to the chassis of the
vehicle. Use 2 gauge insulated wire or thicker.
7. Connect the remote power terminal of the unit to the remote
turn-on switch of your source unit. Alternatively, you can skip
this connection and use the GTO Signal sensing which is ex-
plained later in this manual.
8. Connect your audio inputs to the unit – either speaker-level or
line-level RCA… not both.
9. Run the optional ACR-1 remote to the front of the vehicle to
adjust the bass level on the fly.
10. Connect your subwoofer (2 Ohms minimum load).
11. When all connections are made, reconnect the vehicle battery.
12. Adjust your input source gain using the Patent Pending MILC.
This will indicate if the incoming audio signals are clipping.
13. Set the LC-1.1500 crossover to the frequency recommended by
the subwoofer manufacturer.
14. The optional ACR-1 adjusts the overall output level.
15. Enjoy the drive!
