    The HELIX AAC.3 HP is a high-to-low voltage converter that taps a genuine speaker-level signal from a factory amplifier's output and converts it into a clean, adjustable preamp-level signal for an aftermarket amplifier or DSP — letting you add proper aftermarket power to an OEM system without replacing the factory head unit or amp. Its ADEP.3P circuit bypasses the factory amplifier's speaker-load diagnostics so the OEM system doesn't flag a fault when its output is tapped, while also cutting the current the factory amp has to deliver by up to 70%, which keeps heat and load down at the source. The "HP" (High Power) rating reflects its input handling — up to 25V / 155W at 4Ω, well above a standard high-low converter — which is what separates it from the standard HELIX AAC.3, rated to 16V, and makes it the one to reach for on higher-powered factory systems.
