8-channel line output converter for adding outboard amps to your factory audio system (Gray)
Our take on the AudioControl LC8 by Crutchfield's Zak Billmeier
AudioControl's LC8 processor allows you to add aftermarket amps, speakers, and subs to your factory radio, so you can enjoy better sound without losing factory features. It accepts speaker-level signals from your factory radio or amplifier, so you can use it with any system.
Inputs and outputs
The LC8 features eight speaker-level inputs that let you connect amplified signals, including multi-wire cables from Bose® and other premium factory systems up to 400 watts. The LC8 sums all the signals you send it, even if they're actively crossed over by your factory system, so you get a strong, full-range signal for your processors and amps. The LC8 features eight RCA preamp outputs that'll handle anything up to a multi-channel mobile theater system.
Level matching is a breeze
AudioControl couldn't make it much easier to set up your system. Just set your factory stereo to about 3/4 of its maximum volume, and turn the output level controls of the LC8 until the "Maximized" light begins to flicker. Adjust the gain controls on your amps and you're done. You've just matched your levels, so you can count on getting maximum performance and minimum noise from your amp setup.
The optional dash-mount subwoofer controller allows you to adjust the level of your sub channel on the go. The speaker-level inputs sense incoming signals and turn on the LC8, while a built-in 12-volt trigger tells your amps or other gear to turn on.

Speaker Input: The speaker level inputs are compatible with nearly any factory stereo system, even most Bose systems. There are 4 pair of inputs that will accommodate up to 400 watts.
Channel Summing: The LC8 has the ability to sum together multiple input channels (4, 6, or 8) from the factory source unit into 2 channels. This is handy when the factory system has multiple, actively crossed-over signals sent from the OEM source unit or amplifier(s). For example, in some vehicles there is an actively crossed-over tweeter, midrange, and woofer all in the front of the vehicle. The LC8 lets you take all of those signals and sum them together to get a high-quality, full-range, pre-amp signal without the use of any additional cables or hardware.
AutoMode Inputs: When there is no signal present at the channel 4 input, the channel 3 input automatically feeds the channel 3 and channel 4 outputs.
Output Level: The +/- 12 dB output level allows you to adjust the head unit's voltage to the top of your amp's input range; up to 9.5 volts RMS. Each of the four pair of RCA outputs has its own level adjustment.
Auto Turn-on: The main speaker level input has a signal sensing circuit; the unit turns on when there's a speaker level input signal and turns off when the signal disappears.
Remote Output: The +12 volt DC remote output will trigger an amp to turn on whenever the LC8 is on. The remote's maximum current output is 1 amp.
Optional Sub Level Control: With the addition of an optional wired remote (item number 161LC8R), you can easily adjust the output level of channel 4, often used for a subwoofer.
Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.
Terminal Blocks: The power/ground/remote in/remote out terminal and the speaker level input terminals are removable; the wiring is attached to the block, then the block is plugged into the LC8. The terminal blocks will accommodate wire up to 12 gauge.
