Continuous exposure to high volumes of sound may cause permanent hear-
ing loss. High powered auto sound systems are capable of producing
sounds well over 130 dB. Even short periods of play at high volume levels
can impair your ability to hear necessary traffic sounds and may constitute
a hazard. Please use common sense and practice SAFE LISTENING !

TECHNICAL NOTE
BAZOOKA POWER HOOK UP
On the back of all Bazooka El passive models you will find a terminal cup
with two spring loaded terminals, red being positive and black being
negative. Hook the positive speaker output from your amplifier to the red
positive terminal of the Bazooka. Hook the negative speaker output from
your amplifier to the black negative terminal. Repeat these steps for each
Bazooka used.

Do You Have A Phase Problem?
If the bass response in your application appears to be lower then you
expected or sounds muffled and or distorted, you may be experiencing
Phase Cancellation.
Phase Cancellation
When two speakers in the same frequency range produce sound waves
that are inverted from one another or 180° out of phase, the sound
waves will cancel each other out to some degree. This effect will be
heard as a drop in the output level and/or a muffled or muddy quality
in the Bass Response.
The source of this Phase Cancellation can be at any point in the signal
path. The obvious cause of this problem would be a speaker connection
that was reversed in polarity, but that is not always the case. Sometimes
amplifier channels will shift phase 180° for no good reason, or a signal
processor could have a setting for phase that has been set incorrectly or
the source material could just be recorded in error. Also speaker place-
ment and the acoustics of the listening environment can effect the phase.
No matter what or where the cause is located, the solution is an easy one.
