If you are like many people who like the look and features of their factory-installed source unit, but feel your system overall is lacking power and bass, we have good news. The LC8i has high-impedance speaker level inputs that allow it to accept amplified signals (up to 400 watts per channel) from most factory-installed source units (even Bose) and output a high-quality pre-amp signal via standard RCA connectors. This will allow you to add better-quality amplifiers, processors and speakers while keeping the convenience features of your factory-installed source unit. Unlike inexpensive speaker-level and line-output converters available, the LC8i offers high sound quality.
A set of auxiliary RCA inputs connects the audio signal of an iPod or other stereo source into the system through the LC8i. Tapping the included LC8i remote knob will change from Main input to the Aux inputs and tapping again will change the knob function from subwoofer level control to auxiliary volume control.
Most factory-installed source units lack the pre-amp features that make it easy to upgrade with really good-sounding, performance after-market products. One of those key features is a 12-volt trigger that will turn on devices like the LC8i and your external amplifiers. Therefore, we have equipped your LC8i with our unique GTO™ (Great Turn On) Signal sensing inputs. Once the GTO™ inputs of your LC8i detects a speaker level signal on its main inputs, it powers up. When the speaker-level signal goes away, your LC8i will automatically turn-off. Optionally, you can defeat the GTO™ with an internal jumper and use the +12-volt trigger (Remote In) which is also provided.
Since you will be using an external amplifier and processor in your system, you will need the ability to “trigger” or turn-on these devices (a romantic dinner and drinks won’t quite work here). Your LC8i has a high current 12-volt output trigger (labeled Remote Out) that will provide a 12-volt output to trigger these remote devices, when the LC8i is powered up. Please note that this output is not to be used as the main power for these devices.
The LC8i has the capability to combine together multiple (2, 4, 6, or 8) input signals from the factory source unit into 2 channels. This is particularly handy when using the LC8i with a factory system that has multiple, actively crossed over signals being sent from an 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 LC8i 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.
Sometimes in life (and car audio) we need more outputs than inputs. Therefore we have equipped your LC8i with an AutoMode input that takes the channel 3 (rear) input signal and automatically feeds it to the channel 4 outputs to drive a subwoofer amp and crossover, when there is no signal present on the channel 4 inputs. This means your LC8i will accept two input channels and give you four output channels. Or it can accept four input channels and give you six output channels…or it can accept six and give you eight!! It stops at eight by the way. Optionally, you can bypass the AutoMode, with an internal jumper, for certain custom installations.

A very unique dash mount control is provided with the LC8i. This is a multi-function control, and serves to let the user choose between the Main input (factory head unit) and the Auxiliary input (iPod, satellite radio, or other source). The remote also serves to control the Channel 4 (subwoofer) output level. When you are using the Auxiliary input the remote will independently control either the Aux Volume or the Channel 4 (subwoofer) output level.
