Dear customer, Congratulations on your purchase of a Bazooka EL high-performance amplifier. At Bazooka, we are fanatics about accurate music reproduction. Your selection of our products for your sound system indicates that quality sound is also important to you too. At SAS, we take great pride in manufacturing revolutionary audio products, and through the years of engineering expertise, hand craftsmanship and critical testing procedures, we have created the EL high-performance series of amplifiers.
SAFETY PRECAUTIONS Fuse amplifiers power wire at the battery. Be sure to fuse the power wire within 12” of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST, the amplifier's built-in fuse will only protect the power amplifier not the car's battery! Use high grade wire connectors.
FEATURES AND BENEFITS DC Offset Protection This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current. Short Circuit Protection The circuit protects the amplifier from damage due to a short found in the speakers or wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.
Bass Boost For added low frequency performance the amplifiers are equipped with a variable 0~12 dB bass boost @ 45Hz. Line Out (ELA150.1, ELA300.1 and ELA / MAA500.1 Only) One set of full range line outputs have been provided for convenient connection to additional amplifiers in the system. Power Fusing This protects the amplifier against short circuits and excessive current. Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output.
MOUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. Select the location in which you wish to mount the amplifier.

Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system. Connect the amplifier to the car's battery.
SIGNAL CONNECTIONS Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA input terminals of the amplifier. To make these connections, we recommend high quality RCA cables, which are available at your local car audio retailer. Run signal wires away from electrical wires to avoid possibility of induced noise from the car's electrical system (i.e. popping noises or engine noise).
HIGH LEVEL CONNECTIONS (OPTIONAL) High Level inputs have been included to connect the amplifier to a radio without low-level outputs (i.e. factory radio). This connection will allow you to connect directly to the speaker output of the radio with out the need of an external adapter. Determine the type of radio you have and make one of the following connections. CAUTION! Before making any connections determine the type of radio to avoid possible damage to amplifier and/or radio. 94.

SPEAKER CONNECTIONS Make the speaker connections using speaker wire that is at least 16 gauge or heavier. As with any audio component, proper phasing of the amplifier and speakers is essential for strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-).
SPEAKER CONNECTIONS (BRIDGED) The EL amplifiers are capable of being bridged in a mono configuration. This feature allows you the flexibility of using the amplifier to drive a ** subwoofer or a center channel. In this configuration the amplifier sums the right and left channel to deliver one channel (mono) output. Please note: in order for the amplifier to sum right and left signal information, both right and left RCA connections must be made.
SPEAKER CONNECTIONS (TRI-MODE) The amplifier is capable of running in a Mono / Stereo mode. This feature gives the amplifier the ability to run stereo satellites (midbass & tweeter) simultaneously with a mono subwoofer. These connections are more complicated because they require the use of passive crossover networks (Not provided) to divide the frequencies to the speakers. We have included a sample diagram for 4 Ohm connections.
REMOTE BASS CONTROL MODULE (OPTIONAL) Before connecting the remote, it will be necessary to find a mounting location that will be easy to access for adjustment. Once you select your mounting location, you will need to run the control wire from the remote to the amplifier. To avoid possibility of induced noise from the car's electrical system (i.e. popping noises or engine noise), run the cable from the remote to the amplifier away from the car's electrical wiring.
ADJUSTING THE X-OVER AND BASS . (Please note: If you intend to use the amplifier in the Tri-mode configuration, it is necessary to set the crossover control to the “FLAT” setting in order to receive full range output) The “EL” amplifiers are equipped with a built-in variable crossover network allowing you to select the crossover type (i.e. Low-Pass or Hi-Pass) and the desired crossover point.
TROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
