Speaker Requirements

Symptom Possible Cause Action to take

installation carefully, you can avoid situations where the performance and reliability of your system is

compromised. Our authorized dealer has been trained to maximize your system’s sound quality when

Ωspeaker loads when used in Stereo Mode. When

a channel-pair is bridged, the recommended

minimum load impedance is 3Ωfor subwoofer use,

and 4Ωfor 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

operation will resume.

conditions is not recommended and will reduce its

life expectancy. Most speakers designed for car

audio operation are 4Ωimpedance. Connecting

two such speakers in parallel will result in a 2Ω

nominal impedance, which is not recommended

Poor bass response Speakers wired wrong

polarity causing cancellation

at low frequencies

Check speaker polarity and repair as

needed

Crossover set incorrectly Reset crossover referring to the

section of this manual for detailed

instructions

Battery fuse blowing

too low

Check speaker impedance load. If below

2Ωstereo or 4Ωmono, rewire speakers

to achieve a higher impedance

Short in power wire or

incorrect power connections

Check power and ground connections

and repair as needed

Fuse used is smaller and

recommended

Replace with proper fuse size

Too much current being drawn Check speaker impedance load. If below

2Ωstereo or 4Ωmono, rewire speakers

to achieve a higher impedance and

replace with recommended fuse size

Short in power wire or incorrect

wire

Check power and ground connection and

repair as needed

Too much current being drawn Check speaker impedance load. If below 2

Ωstereo or 4Ωmono, rewire speakers to
