Mounting Locations

Engine Compartment
Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will

void your warranty.

Trunk Mounting
Mounting the amplifier vertically will provide adequate cooling of the amplifier. If you will be mounting

it to an existing panel, be sure it’s not prone to excessive vibration (such as mounting to the back of a

subwoofer enclosure). Excess vibration is not recommended for electronic products, amplifiers included.

Mounting the amplifier flat on the floor of the trunk will provide the best cooling, however be cautious

not to deposit baggage and other items over the top of the amplifier. Mounting the amplifier upside

down to the rear deck of the trunk will NOT provide adequate heat dissipation and will severely affect

the performance of the amplifier and is not recommended.

Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient

amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of

the vehicle, you must have at least 1 inch (2.54cm) of air gap around the amplifier’s heatsink. Mounting

the amplifier with less than 1 inch (2.54cm) of air gap around the amplifier’s heatsink in the passenger

compartment will not provide proper cooling and will severely affect the performance of the amplifier

and is not recommended.

Vehicle Electrical System Requirements

Amplifiers (regardless of brand name) will put an increased load on the vehicle’s battery and charging

system. DAT recommends checking your alternator and battery condition to ensure that the electrical

system has enough capacity to handle the increased load of your stereo system. Original equipment

electrical systems which are in good condition should be able to handle the extra load of any DAT ampli-

fier without problems, although battery and alternator life can be reduced depending on your individual

listening habits. To maximize the performance of your amplifier, we suggest the use of a reserve power

"Stiffening"capacitor.

Wiring the Amplifier

CAUTION: Avoid running power wires near the low level input cables, antenna, power leads, sensitive

equipment or harnesses. The power wires carry substantial current and could radiate noise into the

audio system through the audio cables.

1) Plan the wire routing as described in the “Importance of Pre-Plan-

ning” section. Keep RCA cables close together but isolated from

the amplifier’s power cables and any high power auto accessories,

especially electric motors. This is done to prevent coupling the

noise from radiated electrical fields into the audio signal.

When feeding the wires through the firewall or any

metal barrier, protect them with plastic or rubber

grommets to prevent short circuits. Leave the wires

long at this point to adjust for a precise fit at a later

time.

2) Prepare the power wire for attachment to the amplifier

by stripping 5/8 inch (15.9mm) of insulation from the

end of the wire. Insert the bare wire into the B+ ter-

minal and tighten the set screw to secure the cable

in place.

NOTE: The B+ cable MUST be fused 18” or less from

the vehicle’s positive battery post. Choose a location

to install a waterproof fuseholder under the hood

and ensure connections are water tight. If you do not

use the appropriate fuseholder, the connection will

eventually suffer corrosion from moisture and heat.
