Amp & Subwoofer Installation:

You asked—we delivered.
This is the ultimate plug-and-play Alpine 8-Speaker, Amplifier, and Subwoofer upgrade for your non-amplified 2010–2024 Toyota 4Runner. This powerhouse kit includes the Alpine KTP-445U 4-Channel Amplifier, PWE-S8 8" powered subwoofer (with a custom under-passenger seat bracket), and Alpine’s next-gen S-Series speakers—including massive 8" front door speakers for deeper bass and fuller midrange.

Whether you're running the factory head unit or any aftermarket stereo, this bundle is designed for one thing: easy, professional-grade installation without the professional price tag. Our R&D team has engineered every detail to make this a true drop-in solution—no cutting, splicing, or wiring guesswork needed.

JBL Amplified or Non-JBL Amplified?

  • JBL Amplified: If your door speakers have a JBL logo, you do have a JBL system (this kit will not work for you).
  • Non-JBL: No JBL logo? You’re good to go—this kit is made for you.

What’s in the Plug & Play Bundle?

Each system is hand-prepped by the Trail Grid Pro team at our Frederick, Maryland facility. Every connection is pre-wired, soldered, shrink-wrapped, and Tesa-taped for the cleanest install possible. The harnesses are built with length and layout optimized for your 4Runner. Here’s exactly what you’ll receive:

  • Alpine KTP-445U 4-Channel Amplifier
  • Alpine PWE-S8 8" Powered Subwoofer
  • Custom mounting bracket for under-passenger-seat amp + sub install
  • Alpine Bass Control Knob
  • Alpine S2-S80C 8" + 3" Component System (Dash + Front Doors)
  • Alpine S2-S65 6.5" Coaxial Speakers (Rear Doors + Rear Hatch)
  • All required speaker adapters, pre-sized for a seamless fit
  • Plug & Play wiring harnesses to amplify speakers using factory wiring
  • Radio connectors pre-wired, soldered, and shrink-wrapped
  • Pre-attached fork terminals, ring terminals, and wire ferrules for plug-in-ready installation
  • Amp/Sub harness lengths to mount everything under the front passenger seat
  • 10x zip ties and 1x 10mm bolt
