Wiring for 1 SVC 2 Ohm SUBS:

Wiring for 2 SVC 2 Ohm SUBS:

Features:

  • Rockville W15K5S2 K5 Series 15" 2-Ohm Car Subwoofer
  • Peak Power Handling: 2000 Watts
  • Program Power Handling: 1000 Watts
  • CEA Rated RMS Power Handling: 500 Watts
  • 2.5" 4-Layer Black Aluminum Voice Coils Wound with OFC (100% Copper) Wire
  • The wire we use to wind the voice coil is imported from Japan which is way better quality than the standard China wire
  • 60 Oz High Quality Magnet
  • Cast Iron Basket With Black Sanded Finish
  • Fiber Reinforced Ultra Stiff Black Non-Pressed Paper Cone – This cone is very efficient which makes the speaker sound louder even without requiring a lot of power to push it
  • Thick Foam Surround Provides Incredible Sound Quality With Minimal Distortion
  • Blue Stitching Cone Reinforcement Ensures Long Life
  • Paper Dust cap is light weight and efficient helping the sub to play louder even if your amp is not so powerful
  • Chrome-Plated Binding Post Terminals - These are the best terminals on the market and they accept any gauge wire
  • Impedance: Single 2-Ohm Voice Coils
  • Vented Hole on T-yoke Enhances Heat Dissipation
  • Rubber Boot Magnet Covers Make the Woofer Look Nice and Protects the Magnet
  • Mounting Gasket with Rockville branding looks great and Makes it Easy To Mount the Subwoofer Air-Tight
  • High BL Magnetic Motor Gap
  • We use the highest grade black glue that handles extremely high temperatures which allows our woofer to handle even more power than they are rated
  • Cutout Diameter: 13.85 inches
  • Mounting Depth: 5.98 inches
