  4. Adjust the GAIN Control clockwise, listening carefully to the bass output. If you hear distortion, turn the GAIN control counterclockwise to decrease the gain.

Selecting the crossover frequency

Choose the crossover point to suit listening preferences. Turn the dials to the left to lower the crossover point and to the right to raise the crossover point. Exact crossover settings depend on your listening preferences.

Selecting the subwoofer phase

Switch the PHASE back and forth to determine which setting provides the most clean bass output.

Selecting the bass boost

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

The Stadium BassHub mounts inside the rim of the spare tire in your trunk. To mount the Stadium BassHub properly, follow these steps:

  1. Remove the vehicle’s spare mounting post.
  2. Make sure that the spare tire is placed in the trunk with the outside of the tire facing downwards; the back of the rim should be facing you. This will ensure sufficient mounting depth for the Stadium BassHub.
  3. Carefully place the Stadium BassHub inside the rim of the spare tire.
  4. Insert the Stadium BassHub mounting post into the slot in the center of the Stadium BassHub. When it reaches the spare tire mounting bracket, begin turning clockwise to thread the post into the bracket and tighten.
    NOTE: Some applications require the use of the included adapter to provide a threaded slot for the mounting post. Insert the adapter into the spare tie-down bracket and twist to lock into place. Then repeat steps 3 and 4 above.
    NOTE: TO keep from damaging the Stadium BassHub or the spare tire rim, do not overtighten the mounting post.JBL 700BASS600 Stadium BassHub Amplifiers-19
