Installation
Ultimate recommends professional installation of all its products. Should you choose to install this product
yourself, please read this manual carefully and refer to the instructions detailed below. Failure to do so may
result in poor product performance, premature or immediate malfunction, and potential damage to your vehicle
or its contents.
• When selecting a location to mount your amplifier, please ensure proper ventilation is considered. Areas
below seats or in trunks are suitable, so long as air flow is not restricted. Refrain from mounting your
amplifier upside down, as heat will not dissipate effectively, and can result in thermal shutdown or
component failure
• Mount your amplifier using 4 screws, preferably onto a piece of wood. If screwing into the body of the
vehicle, be sure to check for brake, fuel or electrical lines, as well as stay clear of the gas tank.
• Using a minimum of 8 gauge wire for T2-602 / T2-604, or a minimum of 4 gauge wire for T2-5001, run a
power cable directly to the positive terminal of your battery to the ‘+12V’ terminal of your amp. A separate
fuse must be located within 18 inches of the battery to protect the vehicle from a potential short. Total up
the fuse ratings on your amplifiers to determine the fuse size required under the hood.
• Your amplifier should turn on only when ignition is activated. This can be accomplished by connecting an
18 gauge wire to the ‘trigger’ output on your head unit. If you are using an OEM radio, this will not be
available. You must locate a +12v switched circuit to achieve this.
• The ground path is equally important to the positive feed of your amplifier. Find or create a bare metal
spot on the vehicle’s chassis. Using as short a wire as possible, connect to the ‘GND’ terminal using the
same gauge wire as you did for power. The paint on the body must be removed to bare metal.
• If you’re using a low-level output signal from your head unit, ensure to use a high quality RCA cable to
prevent unwanted noise. It is preferred to use the side opposite to the power wire to run the RCA. Failure
to do so can introduce unwanted noise into the input signal which will be heard through your speakers.
• If your head unit doesn’t have RCA, the T2-HLA1 Hi/Lo adapter would be used. For this, it is ideal to tap in
on the speakers closest to the amplifier location. Using regular 18 gauge speaker wire, take left and right
(both positive and negative) signals. Connect directly to the ‘hi-level’ input on your amplifier. Proper gain
settings are required to ensure undistorted sound.
• You have now completed the installation portion of your new amplifier. Please continue to the “Amplifier
Settings” section of this manual to properly configure your amp for maximum listening pleasure.
