Our take on the HELIX EPC5 Easy Plug Cable

by Buck Pomerantz

Plug a sonic upgrade into your car's system directly

Here's a way to upgrade your factory stereo without cutting any wires or losing features like your steering wheel audio controls. First you plug a HELIX vehicle-specific adapter harness into your car's audio system. Then, this 5-meter (16.4') EPC5 cable allows you to connect a HELIX Blue B ONE, B TWO, or B FOUR amplifier directly into your factory system, adding the impact and detail that only an outboard amp can provide.

You can also use this EPC5 cable to connect a HELIX P-DSP signal processor to your system, giving you extensive control over the overall sound. Warranty: 60 days.

Note: You must identify your vehicle to order a HELIX EPC5 Plug and Play cable online if you want the correct vehicle-specific harness. Or, if you prefer, call an Advisor at 1-888-955-6000 to make sure you get the harness that works in your vehicle.

Crutchfield Customer Review (What's this?)
Paid for a professional install. This harness along with the vehicle specific harness was used to hook up a Helix 4 channel amp. Sound quality was terrible. Had to change to a high/low convertor then use RCA cables to the amp which greatly improved the sound. Had to "eat" the cost of this as everything was imbedded in the floor and would have cost extra to remove. Sadly, Crutchfield technical support was lacking. Technician said I ordered wrong harness, but product information disputed his statement.
Easy hookup to factory head unit
Engine noise, poor sound quality.

  • I have a 00 Eldorado with Bose, is there any way to get aftermarket head unit and subs without rewiring everything. [ Lemarr   Feb 26, 2014 ]
  • Thanks for your question Mitchell. Please contact an Advisor by phone or chat to discuss adding speakers to your vehicle. They will be able to help figure out what adapters and/or wiring you will need to accomplish this. [ Jeff Staff  Dec 16, 2013 ]
