HARMAN KARDON BASSLINKII
Owner's Manual

INTRODUCTION
THANK YOU for choosing the Infinity® BassLink® II powered subwoofer. BassLink II has been designed to provide the kind of high-performance lowfrequency reproduction that used to require big, clumsy enclosures, large amplifiers and complex installation. To ensure maximum performance, we strongly recommend that installation be entrusted to a qualified professional. Although these instructions explain how to install the BassLink II in a general sense, they do not show the specific installation methods for your particular vehicle. If you feel you do not have the necessary tools or experience, do not attempt the installation yourself; rather, ask your authorized Infinity car audio dealer about professional installation options. Remember to keep this manual and your sales receipt in a safe place for future reference. HEARING WARNING! Playing loud music in a vehicle can permanently damage your hearing, as well as hinder your ability to hear traffic. We recommend using low volume levels while driving. Infinity accepts no liability for hearing loss, bodily injury or property damage resulting from the use or misuse of this product. YOUR CAR AND BASS REPRODUCTION Depending on the interior volume of your vehicle and the dimensions of the passenger compartment and cargo area, reproduced frequencies below 80Hz may be boosted by nearly 12dB per octave as frequency decreases.This effect, known as the vehicle�s �transfer function� or �cabin gain, plays � an important part in shaping the overall in-car response of the BassLink II. BassLink II is designed to work with your vehicle�s other speakers to reproduce frequencies below 100Hz. Moreover, depending on orientation and mounting location, BassLink II may be �in phase� or �out of phase� with those speakers. The resulting conditions, known as constructive and destructive interference, also play a role in shaping the total frequency response of your system. Fortunately, BassLink II has controls to optimize both of these conditions, and their adjustment is explained later in the manual.

CHOOSING A MOUNTING LOCATION
Choose a mounting location that doesn�t interfere with cargo, fold-down rear seats or the trunk lid. The best location is usually a corner of the trunk or cargo area, as shown in Figures 1 and 2. These locations, in addition to being out of the way, will provide the best sonic reproduction in the 60Hz to 100Hz range because the woofer output will be �corner loaded� against the vehicle�s walls. In any case, BassLink II must not interfere with the safe operation of the vehicle. Figure 1. BassLink II in a car�s trunk.

MOUNTING BASSLINK II
CAUTION: Make sure mounting screws will not puncture wiring harnesses, brake or fuel lines, or the vehicle�s fuel tank. Some or all of these may be located behind or under the mounting surface. HORIZONTAL MOUNTING Position BassLink II so that the controls are facing down and the back of the unit is up. Align the mounting feet as shown in Figure 4. Secure the feet using the supplied machine screws. Securely mount BassLink II to the mounting surface using the four enclosed self-tapping screws. Figure 4. Horizontal mounting of BassLink II.

VERTICAL MOUNTING Position BassLink II so that the heatsink is facing down and the bottom of the unit is up. Align the mounting feet as shown in Figure 3. Secure the feet using the supplied machine screws. Place BassLink II (with its feet) so the controls are easy to adjust. Securely mount BassLink II to the mounting surface with the four enclosed selftapping screws. Figure 3. Vertical mounting of BassLink II.
