TWEETER INSTALLATION
There are two ways to install the AT25 tweeters: Angled surface or fully recessed moun-
ting.
Flat Surface Mounting
The tweeter system consists of three parts: The main tweeter unit, the backside of the
housing adapter and the front ring.
Mark the location where you are going to mount the tweeters. Drill three holes on each
n
side, one main hole with a bigger diameter for the wire and two small pilot holes for the
two screws fixing the tweeter housing to the mounting surface.
Mount the adapter cup with two flathead screws.

Feed the wire through the hole and connect it to the wire extension that goes to the
n
crossover. Align the front ring over the the tweeter main housing, push it down
and turn the ring clockwise to fix it in place (bayonet design).
Flush Mounting
After choosing the best mounting location, make sure there is at least 25 mm of clearance
behind the mounting surface (for the tweeter cross-spring!), before you start to mark or cut
anything!
Cut a hole with exactly 52 mm diameter into the mounting surface using a power drill and
a circle cutter tool.
Secure the flush mount tweeter adapter in the cutout with the metal cross blade and
the two machine screws provided in the mounting accessory kit. Push the main tweeter
down into the rear cup with the frontring on top, turn clockwise to lock it. Feed the wire
through the center hole of the cup and attach the wire to the extension cable that goes to
the crossover.
CROSSOVER WIRING & MOUNTING
The crossover can be mounted in almost any location inside the vehicle. Recommended
places are: Inside the door, under the carpet in front of the door angles, under the dash-
board a.s.o. Just make sure not to install the crossover units, where they may be exposed
to dirt or excessive moisture / water.
Connect the tweeter wires, the wires from the mid/woofers and the main wires coming
from the amplifier to the crossover. Maintain polarities all the way – double check for cor-
rect connection. It is very important to make sure that all the connections are electrically in
phase, which means positive wire (+ or red) is connected to positive terminal, and negative
wire (- or black) is connected to the negative terminal.
Reverse polarity connections, i.e. when a mid/woofer is concerned, will cause a very low
bass output and a messed up front staging.
If longer distances from the amplifier to the crossovers have to be overcome, use good
quality speaker cables with a minimum cross section of 2.5mm². Failure to do so will affect
sound quality in a negative way.
