Owner's Manual

4. SUBSONIC Control

This control is continuously adjustable from 10Hz through 50Hz at 12dB per octave to provide an extra level of

speaker protection from bass robbing power at unheard frequencies.

5. BASS EQ Control

This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to

18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste.

6. LPF (Low Pass Filter) Control

This ﬁlter controls low pass of frequencies and is adjustable from 50Hz through 250Hz to eliminate unwanted

high frequencies.

7. REMOTE LEVEL

This is the connector port for the Remote Level Control. Now the ampliﬁers secondary gain circuit can be

adjusted from the driver’s seat.

8. POWER/STATUS Indicator

This clear LED lights Blue when the power is on—or turns Red constantly when the built-in protection circuitry

is activated. Red indicates a problem with the system in relation to the ampliﬁer (See Troubleshooting Tips).

9. SUBWOOFER OUTPUT

This terminal is the speaker output. Be sure to observe the correct speaker polarity and follow the speaker

wiring diagrams found elsewhere in this owners manual.

10. BATT+ (Power Input Connection)

This terminal is the main power input for the ampliﬁer and must be connected directly to the positive (+) termi-

nal of the car battery. The solderless terminal block is designed to accommodate up to 8-gauge power wire.

11. REM (Remote Input Connection)

All PowerBass Xtreme ampliﬁers can be turned on by applying 12 volts to this terminal. This can be found

on the rear of the source unit in the form of a remote output. If this is not available you can wire to the ACC

position on the key. An 18 gauge wire is sufﬁcient to run the REMOTE.

12. GND (Ground Input Connection)

A good quality ground is required for your PowerBass Xtreme ampliﬁer to operate at peak performance. A

short length of cable the same gauge as your power cable should be used to attach the ground terminal

directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to ensure a

quality ground connection.

NOTE: If installing in a boat, UTV or motorcycle make sure your ground wire is connected to the

negative ( - ) terminal of the battery.
