HELPFUL HINTS BEFORE YOU BEGIN

Please take time to read through this manual and plan out your installation before you begin!

Locate an area in the rear of the vehicle where you would like to place the Bazooka speaker systems. The location you have selected must meet the following requirements in order for the Bazooka to be properly installed in the vehicle:

• The woofer (grill end) should be facing into a corner. (See vehicle placement recommendations on pg. 3)
• Ideally, there should be 2 to 4 inches between the woofer and the corner it is pointing into.
• The mounting area should be carefully checked to be sure that the mounting screws will not damage the gas tank, electrical wiring, fuel lines, or the spare tire during the mounting of the strap bases.
• The strap mounting bases should be screwed securely to a rigid surface that is part of, or anchored to, the structure of the vehicle.

MOUNTING THE BAZOOKA

1. With the top side of the buckle facing up (see Figure 1), lace the strap through the mounting base as illustrated in Figure 2
2. After the strap is completely laced through the mounting base, make a loop with the strap, where it runs across the middle of the base as illustrated in Figure 3. This loop is necessary to access the two mounting holes in the base.
3. Place each mounting base under the Bass Tubes® enclosure so that the apex at the bottom of the tube sits inside the mounting base as in Figure 4.
4. Move the bases so that they are spaced approximately 3″ from each end of the enclosure as illustrated in Figure 5.
5. Remove the Bass Tubes® enclosure without moving the mounting bases and set it aside.
6. Screw each mounting base securely in place with screws provided as illustrated in Figure 3.
7. Remove any slack in the strap by feeding it out of the mounting base on the loose end of the strap opposite the buckle.
8. Place the Bass Tubes® enclosure on the mounting bases and fasten the buckles as illustrated in Figure 7. The strap should loop through the buckle and be tightened securely by holding the strap in place with one hand and pulling the loose end away from the buckle, but against the cabinet.

Technical Note

Due to the jarring and shifting that can occur in a vehicle, the mounting straps may stretch or loosen. We recommend that you check the straps regularly to ensure that your Bass Tubes® enclosure is mounted securely in place.

AMPLIFIED MODELS (BTA6100, BTA8100, BTA10100, BTA6200, BTA8200, BTA10100):

• DO NOT substitute the fuse included with the Amplified Bazooka subwoofer with anything other than the SAME fast-blow current-rated fuse. Substitution or deletion will void the product’s warranty and may cause damage to your car or the amplifier.

SHOULD I USE HIGH OR LOW-LEVEL INPUTS?

• If the source unit has only speaker outputs, use the high-level inputs of the Amplified Bazooka subwoofer.
• If the source unit has both high and low-level outputs, we recommend using the high-level inputs over the low-level inputs due to the configuration of the Amplified Bazooka subwoofer’s balanced input circuit.
• Not all head units, even those that promise high output voltage in their marketing materials, indeed have high-voltage RCA outputs. Because of this, Bazooka Mobile Audio recommends using the speaker level inputs when in doubt – they will always provide sufficient drive level to the amplifier.
• PLEASE NOTE THAT THE WIRING IN A FACTORY STEREO MAY NOT BE ELECTRICALLY IN PHASE EVEN WHEN YOU HAVE MADE THE PROPER CONNECTIONS.
• Take the time after you make your wire connections to run through the quick phase check procedure in the “AM I IN PHASE?” section at the end of this manual, and NEVER USE BOTH high and low-level inputs at the same time!

INPUT SIGNAL CONNECTIONS High-Level Inputs:

• If the source unit has both front and rear speaker outputs, use only one set of speaker outputs for the high-level input of the Amplified Bazooka.
• Connect the GREEN wire from the 14-pin Molex plug of the Amplified Bazooka subwoofer to the source unit’s left(+) positive speaker output.
• Connect the GREEN W/BLACK stripe wire of the plug to the source unit’s left(-) negative speaker output.
• Connect the GRAY wire of the plug to the source unit’s right(+) positive speaker output.
• Connect the GRAY W/BLACK stripe wire of the plug to the source unit’s right(-) negative speaker output.
• When using high-level inputs, take the time after you make all wiring connections to run through the AM I IN PHASE procedure at the end of this manual to confirm that your inputs are in the correct electrical phase and the proper bass response is being produced.

Low-Level Inputs:

• If your source unit only has low-level RCA phono jack output, use only the low-level inputs of the Amplified Bazooka.
• Connect the low-level RCA phono jack inputs of the Amplified Bazooka subwoofer to the source with a shielded RCA patch cord.
• To avoid possible noise problems, be sure to run the patch cord away from all power wires and factory wire harnesses.

HIGH-LEVEL INPUTS (All Models):

• DO NOT make any connections to the Green and Gray high-level input wires of the Amplified Bazooka subwoofer when using low-level inputs, and make sure these wires are insulated to avoid the possibility of a short circuit.

POWER WIRE (All Models):

• The power wire must be fused and connected directly to the positive terminal of the battery to provide a power source with a low voltage drop and low noise.
• Do not make the power connection at the fuse block or any point other than the battery, as improper power sources can reduce output and cause distortion.
• The fuse holder should be connected to the battery’s positive terminal, and the fuse should only be inserted into its holder after all wire connections have been made.
• If you need to lengthen the battery wire, add the required length between the amplifier and the fuse holder, not between the fuse holder and the battery.
• Use 16 gauge or larger wire for A100 models, and 12 gauge or larger wire for A200 models if extending the battery wire.
• Avoid running the power wire next to the input cables of the amplifier, the radio’s antenna or power leads, or near sensitive equipment or harnesses, as it could induce noise.

GROUND WIRE (All Models):

• The ground wire must be connected directly to the vehicle chassis near the amplifier.
• Extending the ground wire in any installation is not recommended, as it can cause unwanted ground loops.
• The ground point in the car should be a piece of chassis metal that is part of or welded to the main body of the vehicle. Painted surfaces should be scraped or sanded clean to expose the bare metal before mounting the ground lug.

REMOTE TURN ON OPTIONS:

• You have several options for connecting the Remote Turn On Wire, listed in the order of preference recommended by SAS.
• The ORANGE wire on the Amplified Bazooka subwoofer’s 14-pin Molex Mini-fit Jr. connector is the Remote Turn On Wire.
• OPTION ONE: For versatility, connect the Remote Turn On Wire to the source unit’s “Accessory,” “Auto-Antenna,” or “Remote” lead.

OPTION ONE (For source units with “Accessory,” “Auto-Antenna,” or “Remote” lead):

Connect the Remote Turn On Wire to any of these leads, which will supply 12 Volts positive when the source is turned on.

• For ALL A100 : Disconnect the Quick Disconnect YELLOW On/Off Jumper Loop from the wiring harness.
• For ALL A200: Set the Auto/off Jumper Clip in the off position (the two rightmost pins), and the Orange wire will supply turn-on voltage to the Amplified Bazooka.

OPTION TWO (Connecting to accessory or ignition point at the vehicle fuse block):

• If the source doesn’t have an Auto-Antenna lead or if it goes down during tape operation, connect the Remote Turn On Wire to an accessory or ignition point at the vehicle’s fuse block.
• This configuration keeps the Amplified Bazooka subwoofer on whenever the ignition is on but may amplify noise or turn on and off transients when the source unit is not in use.
• For ALL EL Amplified, SMSA, and SM10A: Disconnect the Quick Disconnect YELLOW On/Off Jumper Loop from the wiring harness.
• For ALL A200: Set the Auto/off Jumper Clip in the off position (the two rightmost pins), and the Orange wire will supply turn-on voltage to the Amplified Bazooka.

OPTION THREE (Built-in Auto Turn-On Feature, use when Options One or Two aren’t available):

• The Amplified Bazooka subwoofer has a built-in Auto Turn-On Feature that turns on automatically whenever there is music present at the inputs (high-level or low-level input).
• For ALL A100: Locate the Auto/Off Jumper Loop on the wiring harness and plug it in (shipped with the Jumper in the ON Position).
• For ALL A200: Locate the Auto/Off Jumper Clip on the back of the unit and place it in the Auto Position by lifting it off the middle and right-hand pins and reinserting it across the left-hand pins.

ADJUSTING THE CROSSOVER (A200 ONLY):

• The built-in crossover on the Amplified Bazooka subwoofer is an 18 dB per octave electronic low-pass filter with a variable crossover point from 60 Hz to 250 Hz.
• Set the potentiometer labeled XOVER to your desired crossover point, where 60 Hz is all the way to the left (counterclockwise), and 250 Hz is all the way to the right (clockwise).

PHASE SWITCH (All A100 MODELS ONLY):

• Use the phase switch on the Amplified Bazooka if you suspect that the subwoofer is out of phase.
• Correct phase alignment will result in a proper bass response.

SETTING THE LEVEL (ALL A200 MODELS ONLY):

• Locate the potentiometer labeled LEVEL for level control.
• Start with it turned all the way to the left (counterclockwise) to have low or no bass.
• Turn up your head unit until the existing speakers start to clip or distort.
• Adjust the level gain control slowly until the bass volume blends well with the existing high-frequency speakers, providing the proper setting for the level gain control.

LED POWER INDICATOR:

• Properly connected power, ground, and remote will illuminate the LED light:
  • WHITE = OFF
  • GREEN = NORMAL OPERATION
  • RED = PROTECTION MODE (A200 MODELS ONLY)

OPTIONS (All A100 MODELS):

• Remote Bass Control (RBCM-EL):
  • If you want to adjust bass levels easily, you can purchase an optional Remote Level Control.

All A200 MODELS

Remote Bass Control and Crossover (RBCM-RS):

• If you find you like to vary the crossover point in addition to changing the level of bass depending on what you are listening to and want an easy way to make this possible, you can purchase an optional Remote Level and Crossover Control.
• These Remote Controls are accessories that are available from your Bazooka dealer or directly from Bazooka. Be sure to check out other optional accessories for your Bazooka at

PASSIVE MODELS

(BTA6100,BTA8100, BTA10100 ONLY)

On the back of all Bazooka passive single voice coil models, you will find a terminal cup with two 5-way platinum-colored binding posts, 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.

(BT6024DVC, BT8024DVC, BT1024DVC)

On the back of all Bazooka dual voice coil passive models you will find a terminal cup with four 5-way platinum-colored binding posts, 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.

TROUBLESHOOTING

Am I In Phase?

• If your inputs are out of phase and you turn the balance control of your radio all the way to one side, right or left, the bass output from the Bazooka® will increase. When you bring the balance control back to the center position the bass level will drop. This confirms that one of your input channels is wired out of phase with the other.
• When one of the Amplified Bazooka’s High-level Input channels is out of phase electrically with the other High-level Input channel, your Bazooka will sound as if it has little or no output and any output that is produced may sound distorted. If you suspect that your Bazooka is out of phase, use the AM I IN PHASE procedure to diagnose and correct the Bazooka’s output, and a proper bass response will be produced. channels are wired out of phase with the other. To correct this situation, simply flip the phase switch on the amplified Bazooka®. When the input signal is in the correct electrical phase, the level of bass output will be greatest when the balance control of the radio is set to the center position.

Do You Have A Phase Problem?

• If the bass response in your application appears to be lower than 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 placement and the acoustics of the listening environment can affect the phase. No matter what or where the cause is located, the solution is an easy one.

PHASE CORRECTING PROCEDURE

Disconnect all but one Bazooka® from your system. Be sure that any loose wire connections are insulated to avoid the chance of short-circuiting any of the electronic equipment. Listen to the system and take note of the level of the Bass Response. Connect the next Bazooka® and compare the level of the combined output to that of the single unit. If the Bass Response increases, the Phasing is correct and you can repeat this process on the next Bazooka. If the level of the Bass Response drops, the Phasing is incorrect and you should reverse the speaker connections to this Bazooka® and compare again. In short, to INCREASE IS GOOD, to DECREASE IS BAD! Using this method, any number of Bazooka® subwoofers can be kept in absolute phase.

PRACTICE SAFE LISTENING

Continuous exposure to high volumes of sound may cause permanent hearing 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!
