Description

Powerbass Air Suspension features a robust polypropylene cone and a rubber surround, ensuring durability and long-lasting performance. The air suspension technology replaces the traditional foam or rubber surround, allowing for greater excursion and better heat dissipation. This results in a more accurate and powerful bass response. The subwoofer is designed to fit into most standard car audio enclosures, making it a versatile choice for car audio enthusiasts.

ENCLOSURE PLACEMENT RECOMMENDATIONS

Your PowerBass Air Suspension 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 achieving good sound reproduction as with full-range systems. Typical locations include behind or under the seat in a pickup truck, coupe 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. This custom enclosure is heavy and has a smooth surface finish, which may slide around during aggressive driving, sudden stops, or road vibrations. 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 guideline. 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.
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 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. 14-gauge or larger should be adequate. (Speaker wire not included)

Your PowerBass Bass Air Suspension 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. The port tube (vent) openings cannot be obstructed. At some frequencies most of the bass will come out of the port tube. Therefore we recommend you leave at least 3-inches (7.62cm) between the port tube openings and interior surfaces such as side panels, seats and doors.

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. Even when the enclosure is placed inside a car trunk with no opening to the passenger compartment, the Bass Reflex design will produce strong and full bass.

WIRING AND CONNECTIONS

The PowerBass Air Suspension 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 Air Suspension system.

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

Your PowerBass Air Suspension Subwoofer system will operate at optimum performance after a break-in period.
Allow the system to play 20 to 30 hours at moderate levels.
To sufficiently drive either the Single Woofer 10 or 12-inch system, we recommend using an amplifier with at least 150 watts RMS mono output.

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 refer-ence 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.

Setup Guide

To set up the Air Suspension Subwoofer,

First, choose a suitable enclosure that satisfies the requirements of the subwoofer.
Make sure you have the enclosure ported or sealed appropriately.
Make sure the subwoofer's power and impedance ratings match before connecting it to your vehicle's amplifier.
Install the subwoofer firmly in the enclosure by following the wiring and setup guidelines provided by the manufacturer.
Lastly, adjust the bass settings on your car's audio system to get the finest possible sound.

CARE AND CLEANING

The enclosure is constructed of the same non-resonant material used for premium quality home audio speakers, but covered in vinyl instead of veneer.

A damp cloth is best to wipe down any dirt on its surface.
Avoid using strong cleaners that may discolor the vinyl wrap.
Never apply water or cleaner to the woofer cones.
