DESCRIPTION

Clarion has crafted its car audio amplifier to fit a variety of system configura­tions. The following is a list of features:

• Full frequency response with low distortion and exceptional
signal-to-noise performance.

• Advanced circuitry design features bridgeable outputs for use in a
variety of applications.

• Independent electronic crossovers, each with a 12dB (12/24dB - DPX1001.1)
per octave slope and full adjustment range from 50Hz to 5.8KHz, (50Hz to
580Hz - DPX1001.1) to aid in audio system design.

• Bass boost circuit to reinforce low frequency signals that may be lost
due to subwoofer box design.

• Adjustable input level controls with ground loop isolation, accepting a
wide range of input signals.

• Remote turn-on with “soft start” muting to prevent turn-on “thump”.

• Protection circuits for overheating and speaker shorts.

• 2-ohm load capable to drive a variety of speaker systems.

• Gold-plated input/output connectors and an external automotive- type
fuse.

• Aluminum heat sink for efficient heat dissipation.

• Low profile, compact size to accommodate space limitation.

PRECAUTIONS

INSTALLATION

This section lists mounting and wiring precautions prior to installing the Clarion
amplifier. These safeguards provide enough detail to complete an installation suc­cessfully. Do not attempt to install the amplifier yourself, if you do not have the nec­essary skills. Instead, see your authorized Clarion dealer for installation recommen­dations.

MOUNTING

PRECAUTIONS

Although the Clarion amplifiers incorporate heat sinks and protection circuits, mount­ing the amplifier in a tight space without any air movement will result in damage to
the amp’s internal circuitry over time. Choose a site that provides adequate ventila­tion around the amplifier. For easy system setup, mount the amplifier so the front­panel controls are accessible after installation.

In addition, observe the following precautions:

1. For the most efficient cooling, mount the amplifier so cool air runs along the length
of the fins rather than across them. Remember, any moving air will dissipate heat.

2. Mount the amplifier on a rigid surface. Avoid mounting to subwoofer enclosures or
areas prone to vibration. Do not install the amplifier on plastic or other combustible
materials.

3. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank,
fuel lines, brake lines (under chassis), or electrical wiring.

WIRING

PRECAUTIONS

Read all wiring precautions. If you are not sure of the connections, contact your
authorized Clarion dealer.

1. Before installation, make sure the source unit’s Power switch is in the OFF posi­tion.

2. Disconnect the negative (-) lead of the battery before making any power connec­tions.

3. When making connections, be sure that each connection is clean and secure.
Insulate final connections with electrical tape or shrink tubing. Failure to do so may
result in damage to your equipment.

4. A secure, clean ground connection is critical to the performance of your Clarion
amplifier. Use the shortest ground wire possible and securely connect to the vehicle’s
chassis to minimize resistance and avoid noise problems. Be sure to clean off any
paint prior to making this connection.

5. Add an external fuse on the amplifier’s positive (+) power lead and connect it as
close as possible to the vehicle’s (+) battery terminal. Use a fuse rated to the total cur­rent consumption of the amplifier(s). Adding an external fuse will protect the electri­cal system from short circuits that can result in a fire.
