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-
Planning” section. Keep RCA cables close together but isolated
from the amplifier’s power cables and any high power auto ac-
cessories, especially electric motors. This is done to prevent	Wait to insert
coupling the noise from radiated electrical fields into	fuse until last
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 ampli-

fier by stripping 5/8 inch (15.9mm) of insulation from the end of the wire. Insert the bare wire into the B+ terminal 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.
