System Planning

Proper system planning is the best way to maximize your amplifier performance.

By planning your installation carefully you can avoid situations where the perfor-

mance of the reliability of your system is compromised. Your authorized dealer

has been trained to maximize your system’s sonic potential. Your dealer is a

valuable resource in helping you with your system design and installation.

Speaker Requirements

Each channel of your amplifier can easily

drive 4Ωspeaker loads when used ion the

stereo mode. When a channel-pair is bridged,

the recommended minimum load impedance

is 3Ω for subwoofer use, and 4Ω for full range

operation. Although operation with lower

impedances is not likely to cause immediate

damage to the internal circuitry, the unit will

most likely overheat, causing the thermal

protection circuitry to shut down the amplifier.

When the chassis cools down, normal

operation will resume. Continuing to operate

the amplifier under these conditions is not

recommended and will reduce its life

expectancy.

Most speakers designed for car audio

operation are 4Ω impedance. Connecting

two such speakers in parallel will result in

a 2Ω nominal impedance, which is not

recommended for use with bridged

channels of your amplifier.

Symptom

Distorted output

(cont’d)

Poor bass response

Battery fuse blowing

Amplifier fuse blowing

Possible Cause

Speakers are blown

Speakers wired wrong

polarity causing cancellation

at low frequencies

Crossover set incorrectly

Impedance load to amplifier

too low

Short in power wire or

incorrect power connections

Fuse used is smaller than

recommended

Too much current being drawn

Short in power wire or

incorrect

Too much current being drawn

Fuse used is smaller than

recommended

Action to take

Check system with known

working speaker and repair

or replace as needed

Check speaker polarity and

repair as needed

Reset crossover referring to

the multi-cross crossover

configuration section of this

manual for detailed instructions

Check speaker impedance load,

if below 2Ω stereo or 4Ω mono

rewire speakers to achieve a

higher impedance

Check power and ground

connections and repair as

needed

Replace with proper fuse size

Check speaker impedance load,

it below 2Ω stereo or 4Ω mono

rewire speaker to achieve a

higher impedance and replace

with recommended fuse size

Check power and ground

connections and repair as

needed

Check speaker impedance load.

It below 2Ω stereo or 4Ω mono

Trouble Shooting Power Connection Leads

Notes on the power supply

Connect the +12V power input lead only after all other leads have been connected.

Be sure to connect the ground wire of the unit securely to a metal part of the car. A lose

connection may cause a malfunction of the amplifier.

REMOTE: The unit is turned on by applying +12Volts to this terminal. This terminal

does not draw heavy current like the two power terminal so a thinner connecting wire is

acceptable. Standard 18 GUAGE is fine and the standard color is yellow. If the power

antenna wire is already in use, you can still splice into it. With this method, the unit will

turn on automatically with the radio. Use the power supply lead with a fuse attached

whose value is the same as original fuse.

Place the fuse in the power supply lead as close as possible to the car battery.

During a full power operation. Maximum current will run through the system. Therefore,

Make sure that the leads to be connected to the +12V and GND terminals of the unit

respectively must be larger than 10-Guage (AWG 10)
