INSTALLATION CONSIDERATIONS

Before beginning any installation,follow these simple rules:

1. Be sure to carefully read and understand the instructions before attempting to
install these speakers.

2. For safety, disconnect the negative lead from the battery prior to beginning the
installation.

3. For easier assembly, we suggest you run all wires prior to mounting your speakers
in place.

4. Use high quality connectors for a reliable installation and to minimize signal or
power loss.

Think before you drill! Be careful not to cut or drill into gas tanks,fuel lines,

brake or hydraulic lines,vacuum lines or electrical wiring when working on any
vehicle. If installation in a boat, take care not to cut or drill through the main hull.

6. Never run wires underneath the vehicle.Running the wires inside the vehicle or

7. Avoid running wires over or through sharp edges. Use rubber or plastic
grommets to protect any wires routed through metal, especially the firewall.

eet Dual Clamp (DDC™)

Discr
Tweeter Mount

Every aspect of the new Tweeter design has been
completel

y re-engineered to allow for maximum
ease of installation and fitment.This optimized
patent pending design provides concentric
clamping pressure around the perimeter of the
mounting hole.

The “mounting cups” are in fact not “cups” at all,
but rather unobtrusive “clamps” that quickly
and easily mount in a standard 1.75 inch (45mm)
hole saw opening with a single center screw
securing with balanced pressure to both faces
of the mounting surface. From there, the tweeter
simply snaps into place and is secured by a
snap-on trim ring. Removal is easy if needed.
The protective grille on the tweeter is
non-removable and an intergral part of the design.

WIRING

T2T-S Crossover Wiring

1. Use illustration for proper connection.

2. Be sure to maintain speaker polarity.

3. Connecting the positive wire to 0dB matches the

amplitude of the tweeter to the mid-range (woofer).

4. Connecting positive wire to -2dB or -4dB to reduce

the amplitude of the tweeter -2dB or -4dB lower
than the mid-range, (ideal for tweeters located high
in door panels and mid-range low in the kick panel).

1. Use illustration for proper connection.

2. Be sure to maintain speaker polarity.

Axis ON-OFF Switch

1. Set to ON or OFF to match position of tweeter rela­tive to listener. Default OFF position satisfies most
installations.

dB Switch

1. 0dB matches the amplitude (no increase/no attenuation)
of the tweeter to the same level as the mid-range
(woofer).

2. +2dB increases and -2dB reduces the amplitude of
tweeter in relation to the mid-range, (ideal when match­ing offset installation like tweeters located high in door
panels and midranges low in kick panels).

T252-S & T2652-S Bi-Amp Cossover Wiring

1. Use illustration for proper connection and be sure to maintain speaker polarity.

2. Remove 4 screws from crossover bottom to detatch cover.

3. When BI-AMP switched OFF for one amplifier, use only “TWT” input.

4. When BI-AMP switched ON for two dedicated amplifier, use both “TWT” and “WFR” inputs.
