SYSTEM SETUP

Ampliﬁers (regardless of brand name) will put an increased load on the vehicle's battery and charging system. Diamond Audio

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 Diamond Audio ampliﬁer 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 (1 Farad per 1000W).

WARNING:

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 vehicle 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+

terminal and tighten the set screw to secure the cable

in place.

WARNING:

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.

3. Trim the power cable within 18 inches (45.7mm)

of the positive battery post and splice in an in-line

fuse holder. DO NOT install the fuse at this time.

4. Strip 1/2 inch (12.7mm) from the battery end

of the power cable. Crimp and soldier a large ring

terminal to the cable. Connect the ring terminal to

the positive (+) battery post.
