An extremely compact, slimline subwoofer. The ASS1010 has been
developed with flexibility and functionality in mind. The 78mm high
active subwoofer can be mounted vertically or horizontally. It takes up
a minimum amount of space in the boot, under the parcel shelf and
virtually disappears under the seat.
Inside the ASS1010 sealed enclosure is a 640 Watt Max amplifier that
supports a powerful sound experience. The subwoofer delivers a clear
and strong sounding bass. Equipped with high level inputs the unit will
also amplify a pair of speakers.
If your goal is quality sound without compromising your boot space, this
is the subwoofer for you. Small and compact allowing installation under
the passenger seat. Don’t be fooled by the size the 640 Watt Max
amplifier ensures you are not short on power.

Safety
Alteration or modifications carried out without appropriate authorisation may
invalidate the users right to operate the equipment and void warranty.
CAUTION
Never replace the fuse with one of greater value. Use of improper fuse•
could result in overheating, smoke and could cause injury including burns.
WARNING
Do not touch amplifier with wet hands. Risk of shock.•
For traffic safety and to maintain safe driving conditions, keep the volume•
low enough so that you can hear normal traffic sounds.
Check the connections of the power supply and speakers regularly. If a•
fuse blows solve the problem before replacing with a new fuse of the same
rating.
To prevent malfunction of the amplifier and speakers, the protective•
circuit will cut the power supply to the amplifier. In such case, switch off
the system and check all connections. Detect the cause and solve the
problem.
Contact your installer or dealer if you can not solve the problem.•
To prevent an electric shock or short circuit during installation be sure to•
disconnect the negative battery terminal beforehand.
Confirm that no parts are behind the panel when drilling holes for•
installation of the amplifier. Be sure to protect cables and important
equipment such as fuel lines, brake lines and electrical wiring from
damage.
DO NOT allow amplifier to come into contact with liquids. Electrical shock,•
amplifier damage and speaker damage could result. In addition, the
amplifier surface and of any attached speakers could become hot to touch
and minor burns could result.
If there is smoke or any peculiar odor present during use unplug the•
power cord.

Installation
Before you drill or cut any holes, investigate your car’s layout very carefully.
Take special care when you work near the gas tank, fuel lines, hydraulic lines
and electric wiring.
Step 1:
Place the mounting brackets on the
aluminum base and fix them tightly
with the 4mm x 8mm screws.
Step 2.

which to mount the subwoofer. A typical
location is shown (right). Other areas
include: boot and under the parcel shelf.
Make sure there sufficient air
circulation around the intended
mounting location.

Place the subwoofer in the desired
location. Mark screw mounting points
and drill out with 2.5mm (1/8 inch) drill.
Mount using the 4 x 15mm screws.
Step 4
Attaching the bass boost remote control,
mount with mounting screws (4mm x 15mm)
at an easily accessible location such as
