World's smallest 4-channel line output converter

The Axxess AXLOC4M-150 is a universal factory integration device that converts speaker-level signals to pre-amp outputs for aftermarket amplifiers. It accepts four channels of input at up to 150 watts per channel continuous power. Adjustable gain potentiometers on each channel allow precise output matching. The unit is designed for DIY installers adding amplifiers to factory audio systems.

12-volt signal sense with crossover correction

The built-in 12-volt signal sensing circuit powers the converter on automatically when the factory radio turns on. Input circuitry corrects the crossover distortion typical of standard line output converters. A 6:1 high-to-low step-down ratio reduces signal voltage cleanly. The design handles 150 watts per channel continuously without overheating during normal operation.

Compact universal fit for tight installations

Its miniature chassis fits behind dash panels or in confined spaces where larger converters cannot go. Four-channel input suits front and rear speaker pairs from a single factory head unit. No external turn-on lead is required thanks to the DC offset detection. The converter frees up RCA outputs for amplifier connection while preserving factory wiring integrity.

Questions about this item

How do I wire the AXLOC4M-150 into my factory speaker leads and where is the gain adjustment?

Connect each of the four high-level inputs to the corresponding speaker wires, then use the 12-volt signal-sense wire for remote turn-on; adjust each channel's output level with its onboard potentiometer.

What maintenance will the AXLOC4M-150 need over time?

No scheduled maintenance is required; periodically check that the gain pots remain at the desired setting and that all wiring connections stay tight.

At what power level does the AXLOC4M-150 hit its thermal limit during continuous play?

The converter is rated for 150 watts per channel continuous input without overheating.
