Our take on the HELIX PP-AC28 Plug and Play Harness by Crutchfield's 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 stock radio and speakers, inserting the HELIX PP52DSP or PP82DSP signal processor into the chain. Each 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, along with a built-in amplifier that boosts performance up a notch or two. You'll enjoy focused, clear, and powerfully moving music from your car's factory radio. Warranty: 60 days.
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.

Why Shop With Us?10 Reasons.
Overview: This vehicle specific harness makes adding select Helix amplifier/digital signal processors 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 much easier (supplies the P-DSP with a speaker level signal input, power, and ground). Please confirm compatibility using the Crutchfield Vehicle Selector.
