3. adjust the GAIN control clockwise, listening carefully to the bass output. if you hear distortion, tum the GAIN control counterclockwise to decrease the GAIN.

4. Switch the PHASE back and forth to determine which setting provides the cleanest bass output.

5. Adjust the LOW-PASS control until the BassPro 12 plays only low·frequency information -you should not hear elements such as vocals coming from the woofer.

6. Adjust the BASS-BOOST control clockwise counterclockwise to suit your taste.

The JBL® GT-BassPro12 powered subwoofer pumps out lush, car-rocking bass through a design so cool you won’t want to hide it in your trunk. The patented Slipstream port design delivers a deep bottom end while minimizing turbulence. Turbulence, or port noise at high volume, isn’t just annoying; it’s a signal that the port is no longer working and you’re getting less bass than you paid for. The Slipstream design is carefully optimized for the combination of woofer, amp, and enclosure, and no other company has it. And with the included remote control for drive-time adjustments, the only time you’ll need to stop is for gas.

  • Remote control lets you adjust the sound from the driver’s seat ­ no more stopping to pop the trunk
  • slipstream port eliminates port noise and provides distortion-free bass at high output levels
  • Input level, low-pass, bass-boost, and phase controls make it easy for any user to get the desired sound
  • Speaker-level and line-level input connections allow for use with any audio system
  • Signal-sensing turn-on automatically turns the subwoofer on and off when the head unit sends an audio signal; can be defeated for use with aftermarket radios that include a remote turn-on lead
