Description


Install Bay brand icon

Authorized dealer

Overview:

Simplify your install with this all-in-one solution.
This 20-foot, 9-conductor wire from Install Bay makes amp and speaker installations much cleaner and easier. With nine individually jacketed 18-gauge wires bundled in a tough PVC outer jacket, this cable is designed to handle multiple tasks in one easy run — saving you time and effort.

Versatile Use Cases:

  • Adding a 4-channel amp? Use this wire to send speaker-level output back to the radio location for connection to factory speaker wires.
  • Replacing your head unit? It’s perfect for bypassing a factory amp by routing speaker signals directly from your new stereo.
  • Installing an amp in a remote location? This cable lets you run speaker-level signals and a remote turn-on wire from your factory head unit with ease.

Built for Installers:

  • Color-coded to match standard aftermarket wiring for easy identification
  • Oxygen-free, tin-plated copper conductors for improved reliability and reduced oxidation
  • One clean cable handles four speaker channels and a remote turn-on lead

Key Features:

  • 20 ft. 9-conductor, 18 AWG wire
  • Durable outer PVC jacket
  • Includes 4-channel speaker wires and remote turn-on wire in a single jacketed cable
  • Individually jacketed, color-coded conductors
  • Ideal for OEM integration and custom installs
  • Compatible with most vehicles
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Easy to use

Good, quality, design and flexible.

By JMR on December 30, 2025 Checkmark Icon Verified purchase

Great speaker/remote all-in-one cable!!

This cable is great if you're using for door speakers running no more than 100 rms watt & needing a remote turn on wire. Cable is flexible for most applications, may not be for sharp curves; but worth it. The only thing I did not like is the foam wrapping around the remote wire(blue), unsure the reason for it.
