Add amps to your factory system and play music from your phone
AudioControl's LC8i 8-channel line output converter (LOC) allows you to add aftermarket amps, speakers, and subs to your car's factory radio, so you can enjoy better and more powerful sound without losing climate controls, voice-activated functions, or other built-in factory features. The LC8i accepts speaker-level signals, so you can use it with just about any setup, even high-powered amplified systems.
Now you can plug your music into the system
The LC8i features RCA auxiliary inputs, with an independent volume control, so you can play music through the system from whatever portable source you own via its headphone jack and an adapter cable (not included).
Summing
The LC8i sums its input signals together, even if they've been crossed over for tweeters, mids, and subs by the factory system. That way, you can count on a strong, smooth, full-range signal for your processors and amps. The LC8i features eight RCA preamp outputs that'll handle a 4-way system using tweeters, mid-high speakers, mid-low drivers, and subwoofers.
Level-matching with an LED indicator
AudioControl makes it easy: set your factory stereo to about 3/4 maximum volume, turn the output level control of the LC8i until the "Maximized" light begins to flicker, then adjust the gain controls on your amps and you're done. You've level-matched the output of your receiver to the amplifier's input, so you can count on getting maximum performance and minimum noise from your system.
Convenience
The included dash-mounted wired remote allows you to adjust the volume of the auxiliary channel and bass while you're on the go. The speaker-level inputs sense incoming signals and turn on the LC8i, while a built-in 12-volt trigger turns on your amps as well. If your factory system only has channels for highs, mids, and lows, for example, AutoMode™ will create the output you can use for your subwoofers.
