Learn how to install a dual 10" loaded subwoofer enclosure under the rear seat of your Chevy Silverado or GMC Sierra for a powerful audio upgrade.
Quick Answer
Installing a dual 10" loaded subwoofer enclosure under the rear seat of your Chevy Silverado or GMC Sierra is straightforward with the right fit and a few basic tools.
Why a Dedicated Enclosure Matters
A pre-loaded enclosure like the AudioControl TXGM19D10 is engineered to fit perfectly beneath the rear seat of 2019+ Chevy Silverado and GMC Sierra trucks. This eliminates guesswork with dimensions and ensures the subwoofers are matched to the enclosure volume for optimal performance.
Tools You’ll Need
Gather a socket set, wire cutters, a screwdriver, and a torque wrench. You’ll also need a power drill if your truck lacks pre-threaded mounting holes. Have speaker wire and RCA cables on hand for the amplifier connection.
Installation Steps
- Disconnect the Battery: Disconnect the negative terminal of your truck’s battery to prevent any electrical shorts while working near the amplifier and wiring. Always double-check that the battery is disconnected before touching any power wires.
- Remove the Rear Seat: Lift the rear seat bottom by pulling up on the front edge. On most models, it unclips without tools. If your truck has bolts, use a socket to remove them. Store the bolts in a labeled bag so you don’t lose them during reassembly.
- Position the Enclosure: Slide the AudioControl TXGM19D10 enclosure into the space beneath the rear seat. Ensure it sits flush against the floor and does not interfere with seat belt anchors or floor vents. Test the fit before securing anything; the enclosure must not shift when the seat is lowered.
- Secure the Enclosure: Use the provided brackets or self-tapping screws to fasten the enclosure to the truck’s floor. Tighten screws to 8–10 ft-lbs to avoid cracking the fiberglass. Over-tightening can crack the enclosure, so use a torque wrench if available.
- Connect the Amplifier: Run speaker wire from the amplifier to the enclosure’s input terminals. Match positive to positive and negative to negative. Use RCA cables for the signal connection from your head unit. Verify polarity by checking that both subwoofers move in the same direction when playing a test tone.
- Reinstall the Seat and Test: Lower the rear seat back into place. Reconnect the battery, turn on the system, and play a bass-heavy track at low volume to confirm operation. Gradually increase volume to check for rattles. If you hear distortion, reduce the gain on the amplifier before continuing.
