More and more aftermarket amplifier installations depend on using the factory amp's powered outputs for its inputs. AudioControl's LC2i PRO line output converter takes amplified speaker-level signals and converts them into high-quality preamp signals that can then be fed to another processor, a full-range amplifier, or your subwoofer amp.

AudioControl's LC7i 6-channel line output converter (LOC) with bass restoration 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 LC7i accepts speaker-level signals, so you can use it with just about any setup, even high-powered amplified systems.

Aftermarket amplifiers and DSP sound processors need clean and strong input signals, whether they come from a receiver's RCA outputs or a factory amp's speaker outputs. AudioControl's LC1i line output converter can produce up to 9.5 volts of preamp-level output in either case, acting as a line driver using its RCA inputs or as a line output converter using the speaker-level inputs.

AudioControl's LC6i 6-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.

AudioControl created the Overdrive Plus line driver to ensure that your amp sees the cleanest signal possible. Many modern car stereos boast 4- and 5-volt preamp outputs, but they're rated at full output. Turn your stereo to a normal listening level, send the signal through a 20-foot cable, and your amps may end up with just a couple of volts. The Overdrive Plus solves this problem by boosting the signal from your car stereo, and it also allows you to control your amp's level from the front seat with an optional remote.

AudioControl's Matrix Plus 6-channel line driver will ensure that your sound processors and power amplifiers receive strong, clean signals to perform their best. Many car receivers boast 4- and 5-volt preamp outputs, but that's at full power. Turn it down to a normal volume level, send the signal through fifteen feet of RCA cabling, and your amps may end up with just a couple of volts — not enough for good clean amplification. Enter the Matrix Plus.

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

We're encountering more and more instances where the factory stereo system in a vehicle can't be replaced or bypassed, so any aftermarket amps and processors have to use the speaker wiring in order to get signal. We've also found that not all wires carry a full-range signal — high frequencies go to tweeters, midrange sounds may go to door speakers, and low frequencies go to a factory subwoofer — making it pretty complicated to access a full-range signal for your aftermarket system.
