Amplifier shuts down after playing for a period of time

Thermal protection circuits are shutting the amplifier off: Check the location for adequate ventilation. Relocate amplifier as required. Consult an authorized Clarion audio dealer.

Distorted audio

Gain is not properly set properly: review the instructions for setting the gain.

Speaker cones are damaged: inspect each speaker cone for signs of damage, such as a frozen cone, burnt smell, separated or ripped surround or separated spider.

Amplifier fuse keeps blowing

Incorrect wiring or short circuit: review the installation and check all wiring connections.

Amplifier being driven too hard: Turn down the volume, gain or bass boost.

Undersized or faulty fuse installed: Replace the amplifier fuse with the same rating fuse as the one that shipped with the unit.

Note:

The DPX11500 ships with a 200 Amp, ANL-type fuse; mount it external to the unit, near the battery.

Whining noise when engine on

RCA cables too close to the power wire: Separate RCA and power cables.

Ground loops are caused by a mismatch in the ground potential (voltage) between two sources. Current flows through the shield of the RCA cable and is quickly picked up by the amplifier. There are several ways to solve this problem:

Re-ground the amplifier to a more electrically conductive location.

Re-ground the head unit to a more electrically conductive location.

Run a ground wire from the head unit to the amplifier ground.

Upgrade or replace the ground wire on the battery and alternator.

Run a ground cable from the negative terminal of the battery to the amplifier.

Wire the entire audio system using a single connection point to the chassis.

Induced noise: Relocate components away from electrical noise sources:

Engine control computers

ABS brake control modules.
