If you do not have sufficient experience or tools to carry out the installation, it is
imperative that you seek the assistance of someone who does, or have the
amplifier professionally installed.
Before attempting the installation of this amplifier, it is important to understand that the
TL-1023 is a substantial piece of kit; with an output of 1,000w RMS, this amplifier can
draw large currents from the vehicle battery and alternator. Depending on vehicle model,
one or more of these components may have to be replaced to enable the amplifier to
operate to its full potential.
Modifications to consider:
-
Alternator. The alternator is the heart of the power supply. The diodes will fail if
the standard alternator can not supply enough current. An up-rated alternator will
not leave the amplifier starved of power. It is best to seek advice from
professionals who specialise in your make and model of vehicle to source an up-
rated alternator. Dual alternator setups are also recommended.
-
Up-rated battery. A high rated van battery/specialist audio battery will enable
higher current to be drawn by the amplifier. Replacing the standard battery with an
up-rated one is highly recommended. It is best to speak to a professional who
specialises in batteries.
I
deally use one suited to deep-cycle applications with a
large capacity.
-
Second battery. A second battery installed as close to the amplifier’s positive
terminal as possible, with a split charging relay, ensures that there is a dedicated
battery for the amplifier. This helps protect other components on the vehicle and
keeps resistance down with the short cable run.
-
Split charging relay. As mentioned above. Split charging relays usually used for
boats or caravans are recommended.
TheLoudest.com accepts no liability for any damage resulting to vehicle components when
installing or operating the amplifier. It is the sole responsibility of the user to follow these
instructions carefully and upgrade any vehicle components as required.
The TL-1191 4 AWG amplifier wiring kit is strongly recommended for use with this TL-1023
amplifier. It contains the components mentioned in the installation instructions below.
Failing this, 4 AWG cable and an 80A fuse is an absolute minimum.
Before starting the installation it is advisable to
disconnect the negative terminal of
the vehicle battery
. This ensures the battery will not short if the wires are accidentally
crossed during installation, and is generally good practice when making electrical changes.
Please be warned that after disconnecting the battery, your control unit (head unit) may
require a code to be entered, some car alarms may also sound. Therefore it is best to
disable the alarm before installation and enable it again after installation is complete.
Connect the power (+) cable
(4 AWG red cable) directly to the positive terminal of your
vehicle battery by unscrewing the nut on the positive terminal and slipping on the power
lead connector, before replacing and tightening the nut. The TL-1191 wiring kit includes a
battery terminal block which ensures a very clean connection. There is a fuse holder and
fuse already installed on this cable if purchased as part of the TL-1191 wiring kit. If not
using the kit, you will need to install one about 60 cm from the battery, using at least a
80A fuse.
This power cable then needs to be run to where the amplifier will be mounted. Look
around the engine bay for a place to run the cable through to the inside of the vehicle.
Suitable points are usually bonnet pull grommets or air intake holes. This positive wire

Installation
Below are some basic connection configurations for subwoofers to the TL-1023. Remember that
the TL-1023 has a minimum load of 1 ohm. It is also advisable to use subwoofers which have
similar RMS power ratings, in general, a little under or over should be OK.
These diagrams show the amplifier speaker terminals connected to the subwoofer terminals.
Sometimes this is done directly, but if the subwoofer is inside an enclosure, the connections will be
made via the terminal connection block on the side of the enclosure.
The TL-1023 is a monoblock subwoofer amplifier, so there is one output channel. There are two
sets of positive and negative speaker terminals for ease of connection, they are internally bridged.
Load to amplifier: 2 ohm
Below is the basic completed installation for the TL-1023. This example shows the amplifier
connected to a dual 2 ohm voice coil subwoofer such as the TL-1121:
