∆Warning ∆
Continuous exposure to sound pressure levels in excess of 100 dB can cause permanent hearing loss. PowerBass Autosound
Speakers are capable of producing sound pressure levels well over 170 dB. Please observe all local sound ordinances while
listening to your PowerBass Autosound system. PowerBass USA, Inc. accepts no liability for hearing loss, bodily injury, or
property damage due to the result of use or misuse of this product.

WIRING
Your PowerBass Autosound Tweeters come complete with two (2) in-line 12dB/octave crossovers
that have been computer optimized especially for use with your tweeters. These crossover net-
works have color coded (red/black) speaker wiring permanently attached. After finding the best
location for the crossovers, route the wiring to the radio (or source unit) and to the tweeter mount-
ing location. Join the short wires from the tweeter to the wires from the OUT side of the crossover,
using the clear insulated slip on connectors. Make sure the male/female connections fit securely.
Please be sure to observe the colored wires to ensure proper polarity. Be careful the wiring for the
crossover does not interfere with the window mechanism, door locks, etc. The wiring that goes to
the source can be connected as required.
NOTE: The tweeter must be wired to the side labeled OUT from the crossover network. Failure
to do so will damage the tweeter.

INSTALLATION PROCEDURES
By mounting the tweeter separately from the woofer (or mid-range driver) the installer can choose
the best location for sound quality and imaging. Three mounting types are possible allowing more
versatility for the tweeter location. These are flush mount, surface mount, and angle mount.
FLUSH MOUNTING (Type A) The best location for the tweeter is usually high up on the
door and as far forward as possible without interference from the dashboard. If the desired loca-
tion is flat and space behind the door panel allows the use of the flush mount housing, follow the
drawing as shown below:
After checking for clearance, cut the mounting hole in the door panel (see Tweeter Specifications
for hole size). Mount the Flat Base from the outside with the mounting clip on the inside of the
door panel. Secure the mounting clip to the Flat Base with the long silver screw provided.
SURFACE/ANGLE MOUNTING (Type B and C) If mounting the tweeter on the surface works
out best, refer to the following drawing to see how to best mount the tweeter. Black sheet metal
screws have been provided to attach the surface base to the door panel.

POWERBASS COMPONENT TWEETERS
These high quality tweeters come complete with several mounting housings for installation versatility. Typically
tweeters should be mounted on axis and as close to ear level as possible. After you have chosen the housing to be
used, gently press the tweeter in the proper mounting base. Once the tweeter base is mounted, push and “twist” the
housing until it locks to the base. Below are exploded views showing the possible types of tweeter mounting.
