Bundle contents

This kit combines a 4‑gauge copper amplifier wiring set rated for 1200 W with an AudioControl LC1i two‑channel line‑output converter. It is aimed at installers adding an aftermarket amplifier to a factory head unit. The converter provides active speaker‑level and line‑level inputs with selectable impedance matching. A compact coozy is also included for small‑tool storage.

Factory‑radio upgrade

The LC1i replaces a basic passive LOC by delivering up to 9.5 Vrms preamp output and ±12 dB gain control. Its GTO™ signal‑sensing and audio‑sense turn‑on eliminate the need for a separate remote wire. The jump is worth it when the factory radio lacks RCA outputs or when the installer needs 40 Vrms speaker‑level handling and 20 kΩ/60 Ω/20 kΩ load selection.

Installation checklist

Verify that the vehicle’s speaker wires can supply up to 40 Vrms per channel and that the amplifier accepts a 150 Ω preamp source. Confirm 12 V accessory power for the converter’s 120 mA draw and the always‑active remote output. Ensure the 4‑gauge power and ground cables can reach the battery and chassis ground points without excessive length.

Questions about this item

What size power cable and fuse does the included wiring kit provide for a 1200 W amplifier install?

The kit supplies 4-gauge copper power and ground wire rated for 1200 W, a matching 4-gauge fuse holder, and all ring terminals needed for the battery and amplifier connections.

How do I set the LC1i load-selection switch for my factory speaker wires, and what mistake should I avoid?

Match the switch to your head-unit impedance — choose 20, 60 or 20 kΩ — and do not leave it on the default 20 kΩ setting if your factory system is lower impedance, or the converter will not activate properly.

When should I expect to replace the in-line fuse or check the LC1i ground-isolation switch?

Inspect the 4-gauge fuse holder annually or after any short-circuit event; the LC1i ground-isolation switch only needs toggling if you hear alternator whine after the initial install.
