Overview

Our take on the Helix PP7E Compact Sub

Helix makes the PP7E subwoofer to deliver great bass when you upgrade your vehicle's factory sound system with a PP50DSP or PP52DSP processor and amplifier. The PP7E rocks with twin 7" subs in a vented enclosure that's compact enough to fit in most vehicles, yet strong enough to broadcast some impressive bass.

Proprietary cable included

The PP7E comes with a 15.75-foot PP-SC4 cable that connects the sub to your PP50DSP or PP52DSP processor. You'll need the cable to connect this enclosure, since its two subs contain four separate voice coils, each powered by its own amp channel in the processor.

The Helix PP7E subwoofer works with the PP50DSP
processor and a vehicle-specific harness (not shown).

I love this sub, it offers clear sound and is so easy to install. I love the fact that the specialized cable keeps the power and audio neat and clean looking.

Features

Overview: The PP 7E subwoofer is designed as an easy addition to the HELIX PP50 DSP plug and play digital signal processor/amplifier. The included PP-SC 4 cable connects the proprietary input terminal on the PP 7E to the subwoofer port on the PP50 DSP. The PP50 DSP powers the PP 7E subwoofer and is required for its use.

Driver Size: HELIX describes the size of the two subwoofers as 7" on their web site and on a sticker on the back of the enclosure. On the packing box they are described as 6-1/2". The speakers' frame diameter is similar to 6-3/4" car speakers.

Impedance: Both subwoofers have dual 2Ω voice coils. Each of the four voice coils is wired separately to the proprietary Molex input terminal.

I do not have specifics on the damage to the sub I'm afraid. Our scratch and dent items have some type of minor cosmetic damage, nothing that would affect the products performance, and the items come with the full manufactures warranty. [ Krissy  Jun 13, 2015 ]  Staff
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Krissy  Mar 31, 2014 ]  Staff
