Our take on the Helix PP-SC4 by Crutchfield's Buck Pomerantz
You've decided to upgrade your car's factory audio system with a Helix Plug and Play system. Good move, but don't forget the bass. The PP-SC4 cable connects the Helix PP50DSP processor to a Helix Blue B ONE sub amplifier, allowing you to power large subs. The cable is 15.75 feet (4.8 meters) long, so you can place your amp in almost any convenient location.
You also have the option of using Helix's compact PP7E subwoofer in a Plug and Play upgrade installation. This PP-SC4 cable is included with that subwoofer, so, in that case, you would only need to order this cable if you needed a replacement. Warranty: 1 year.
What's in the Box:
- PP-SC 4 cable with proprietary 8-pin plugs on both ends
Helix PP-SC4 Reviews
Overview: The PP-SC 4 cable connects the subwoofer output port on the PP50 DSP plug and play digital signal processor/amplifier to the speaker-level input port on the B ONE blue subwoofer amplifier. It's also the same cable that's included with the PP 7E subwoofer, so it can be used as a replacement for that unit.
