area, this small footprint sealed enclosure is constructed of 5/8 non-resonant material.

One Piece Injection Molded Cone: This design ensures low distortion bass reproduction and voice coil alignment.

2” Vented KSV Voice Coil Formers: These specially designed resin coated high temperature voice

coils ensure high power handling and precise linear excursion while maximizing thermal heat dissipation.

Large Roll Rubber Surrounds: Allows maximum excursion and precision bass reproduction.

Computer Optimized Acoustic Chamber: Engineered for a tight and accurate bass response in space

prohibitive applications, such as behind seats or inside compact trunks.

Custom Mounting Brackets: Two brackets each with one side marked Vehicle and the other Cabinet. Use

two of the brackets on each enclosure to properly secure the enclosure.

UNPACKING THE ENCLOSURE AIR SUSPENSION

Every attempt has been made to transport your new PowerBass Downﬁring Subwoofer system safely.

Carefully unpack the enclosure and inspect it thoroughly for any damage that may have occurred during

shipping. Notify your local PowerBass dealer immediately should you notice any damage prior to installing

the unit. Be sure to keep the carton and packing material until your system is operational. The original

boxes will do the best job of protecting your speaker system if they need to be transported.

INSTALLATION EXPERIENCE

Installation of PowerBass Autosound Speakers requires experience with a variety of mechanical and electrical

procedures. This manual only provides general installation and operating instructions. If you have any reservations

about your installation skills or lack the proper tools, please contact your local PowerBass Autosound dealer

for assistance.

ENCLOSURE PLACEMENT RECOMMENDATIONS

Your PowerBass Downﬁring Subwoofer system accurately reproduces the lowest portion of the audible

frequency range, which is generally considered to be non-directional. As such, the placement within the

vehicle is not as critical to achieve good sound reproduction as with full range systems. Typical locations

include behind or under the seat in a pick-up truck, crew cab, hatchback and trunks in cars or wherever

space is limited.

Use the mounting brackets and hardware supplied to secure the enclosure to the vehicle.

WARNING: Permanent mounting is not only the safest installation, but usually produces

the best sound quality. To avoid vehicle damage or personal injury please ensure that the

enclosure is securely mounted to a surface with adequate strength and rigidity to support it.

The following placement recommendations and installation tips are the result of many hours of development and

experimentation. These examples are provided to you as a guide line. Please feel free to experiment yourself as

you may ﬁnd that other placements can provide you with superior results.

• Make sure all moving parts and factory electrical wires are out of your way and will not interfere after

installation.

• Should you choose to install the enclosure with the woofer facing down, make sure there is nothing

between the cone and the floor of the vehicle.

• Leave a little slack in the wire to prevent pulling or stretching, this is even more important if the wires will

be run under or through the factory interior.

• Use cable ties and wire clamps to prevent the wires from getting caught or shorted.

• We do not recommend placing or installing loaded enclosures where they might be subjected to moisture.

• Correct subwoofer wiring polarity must be observed. The polarity positive side is marked by a(+) sign.

Subwoofers wired out of phase will produce little bass.

• Speaker wires should be electrically and physically isolated from the vehicle and routed away from any

factory wiring that carries high currents or noise (ie, ABS brake systems and engine computer signals).

• Use speaker wire large enough to carry the full power of your ampliﬁer. 16-gauge or larger should be

adequate. (Speaker wire not included)

• Check before drilling any mounting holes

Your PowerBass Downﬁring Subwoofer system needs to be installed some place where it can operate efﬁciently

and not endanger the occupants of the vehicle.

The location and orientation of your enclosure will affect the quality and quantity of the bass.

If the enclosure is to be mounted all the way in the back of the vehicle, it works best to point the woofer toward

the front of the vehicle. Conversely, if the enclosure is going to be mounted closer to the back seat, pointing the

woofer toward the rear of the vehicle will give you the best results.

WIRING AND CONNECTIONS

The PowerBass Downﬁring subwoofer system consists of a single 4-ohm voice coil woofer. Check to see that

your ampliﬁer is optimized to drive this load.

A single spring loaded push terminal cup provides a quick and easy connection from your bass ampliﬁer to

your subwoofer system.

1/2”

The push terminal input cup is located on the side of the enclosure (Fig 1). For a bare wire connection, strip 1/2

inch (12.7mm) of insulation from each of the two conductors of your speaker wire (not included) to expose bare

metal (Fig 2). Carefully twist each of the conductors to eliminate any frayed ends. Push open both terminals,

line up the holes, and insert the wires from your ampliﬁer as follows: Positive wire (+) to the Red terminal,

Negative wire (-) to the Black terminal. Be careful not to insert the insulated part of the wire into the hole as

this will not give you a good connection.

SOUND CHECK

RECOMMENDED POWER

The PS-DF110T is designed to handle up to 275 watts RMS (continuous) and 550 watts maximum (peak) of

input power. Therefore an outboard ampliﬁer optimized at 4-ohms will be necessary to drive this system. You

will want to use an ampliﬁer powerful enough to provide listening comfort. Generally speaking, an ampliﬁer

with the same or slightly higher power rating than the RMS power handling should be selected.

CROSSOVER SETTINGS

The Downﬁring woofer enclosure is designed to reproduce low (bass) frequencies only. It does not contain

a low pass ﬁlter, therefore a crossover network is required for proper operation. If your ampliﬁer includes an

electronic (active) crossover, it should be set between 80Hz and 90Hz. Optimum adjustment can be achieved after

listening to your favorite music and varying the crossover frequency.

If your ampliﬁer is equipped with a Subsonic Filter it should be set to 25Hz or higher.

BREAK IN PERIOD

To get the most from your woofer we recommend a “break-in” period of at least 40 hours (typically 2 weeks)

at no more than 1/3 of maximum volume. During this time the cone and spider assembly will gradually break

in resulting in greater performance and more listening enjoyment.

CAUTION: Damage to the woofers can occur when an ampliﬁer, regardless of its wattage, is made to play

at higher listening levels than its power can clearly produce (usually beyond the “1 to 2 o’clock” position on

the volume control). This results in very high levels of audible distortion. Contrary to popular belief, a speaker

is more likey to be damaged by trying to get too much volume from a low-powered amp than from a high-

powered amp.

NOTE: Lack of bass output is usually caused by the subwoofer being out of phase with reference to the rest

of the system. In this case reversing the speaker connection from positive to negative on the terminal cup

will correct the problem.

CARE AND CLEANING

The enclosure is constructed of the same non-resonant material used for premium quality home audio

speakers, but covered in a combination of vinyl and carpet instead of veneer. A damp cloth is best to wipe

down any dirt on the vinyl surface. Avoid using strong cleaners that may discolor the vinyl wrap. Never apply

water or cleaner to the woofer cones.

WE WANT YOU LISTENING FOR A LIFETIME

Dear Customer,

Selecting ﬁne audio equipment such as the speakers you’ve just purchased is only the start of your musical

enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers.

PowerBass and the Consumer Electronics Association (CEA) want you to get the most out of your equipment

by playing at a safe level. One that lets the sound come through loud and clear without annoying, blaring or

distortion – and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound.

So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting

your equipment at a safe level BEFORE your hearing adapts.

PowerBass and the CEA want you listening for a lifetime!
