Our take on the Helix PP-AC75 Plug and Play Harness

by Buck Pomerantz

The Helix Plug and Play system

A Helix Plug and Play system will make a dramatic improvement in your vehicle's stock audio system — very cool news if you lease your vehicle or don't want to remove your factory radio.

The system starts with this vehicle-specific adapter harness that plugs in between your car's receiver and speakers, inserting the Helix PP50DSP signal processor into the chain. The processor uses a program developed specifically for your vehicle to transform your system, using sophisticated equalization and time alignment to compensate for the weaknesses in your factory speakers. You'll enjoy focused, clear, and powerfully moving music from your car's factory radio. Warranty: 1 year.

Note: This Helix harness plugs in between your vehicle's factory radio and speakers, so it will not work in a premium sound system equipped with a factory amplifier.

Overview: This vehicle specific harness makes adding the HELIX PP50 DSP amplifier/digital signal processor (item number 975PP50DSP, sold separately) to a compatible vehicle a plug & play solution. It can also be combined with the EPC5 Easy Plug Cable (item number 975EPC5, sold separately) to make installing the P-DSP digital signal processor (item number 975PDSP, sold separately) much easier (supplies the P-DSP with a speaker level signal input, power, and ground). Please confirm compatibility using the Crutchfield Vehicle Selector.
