The following installation instructions are intended to be used as a basic  
guideline. If you feel unsure about installing this speaker system yourself, Dual  
recommendsꢀacquiringꢀtheꢀservicesꢀofꢀaꢀprofessionalꢀcarꢀaudioꢀinstallationꢀ  
center.  
Beforeꢀinstallation,ꢀpleaseꢀreviewꢀtheꢀfollowingꢀguidelines:  
1. Be sure to carefully read and understand the instructions before attempting to  
install this product.  
2.ꢀIfꢀadditionalꢀwiringꢀisꢀrequired,ꢀweꢀrecommendꢀrunningꢀallꢀwiresꢀpriorꢀtoꢀ  
mounting your enclosure in place.  
3. To ensure reliable performance and minimize signal or power loss, use the  
highestꢀqualityꢀconnectorsꢀavailable.  
4.ꢀNeverꢀrunꢀspeakerꢀwiresꢀunderneathꢀyourꢀvehicle.ꢀRunningꢀspeakerꢀwiresꢀ  
insideꢀtheꢀvehicleꢀprovidesꢀtheꢀbestꢀprotectionꢀfromꢀexhaust,ꢀheatꢀandꢀ  
environmentalꢀelements.ꢀ  
5.ꢀAvoidꢀrunningꢀwiresꢀover,ꢀnearꢀorꢀthroughꢀsharp-edgedꢀsurfaces.ꢀWeꢀsuggestꢀ  
you also use rubber grommets to protect any wires routed through metal,  
especially the firewall.  
6.ꢀWhenꢀrunningꢀtheꢀspeakerꢀcableꢀtoꢀtheꢀamplifier,ꢀavoidꢀrunningꢀitꢀnearꢀsourcesꢀ  
ofꢀhighꢀcurrentꢀ(i.e.ꢀwiringꢀharnesses,ꢀbatteryꢀcables).

requireꢀaꢀ17-20ꢀfootꢀRCAꢀcable.ꢀMostꢀtrucksꢀandꢀ  
behind-seatꢀapplicationsꢀrequireꢀaꢀ6-12ꢀfootꢀRCAꢀ

will minimize noise.

Control  
The phase control compensates for delay between  
the ALB10 output and the rest of the sound system.  
Begin with the phase control set to 0 degrees. If  
theꢀsoundꢀisꢀadequateꢀfromꢀtheꢀnormalꢀlisteningꢀ  
positionꢀinsideꢀtheꢀvehicle,ꢀnoꢀfurtherꢀadjustmentꢀisꢀ  
necessary. If the sound is thin or lacking bass, adjust  
the phase control until the bass is full and punchy.

Theꢀinputꢀlevelꢀcontrolꢀ(LEVEL)ꢀisꢀusedꢀtoꢀobtainꢀtheꢀ  
best possible match between the head unit audio
