Theꢀfollowingꢀinstructionsꢀareꢀdesignedꢀtoꢀensureꢀsafetyꢀduringꢀinstallationꢀandꢀuseꢀ
ofꢀtheꢀBAK1500.ꢀFailureꢀtoꢀheedꢀtheseꢀinstructionsꢀcanꢀresultꢀinꢀinjuryꢀorꢀdamageꢀ
toꢀtheꢀunitꢀorꢀvehicle.
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).

The phase control compensates for delay between
the BAK1500 output and the rest of the sound
system. Begin with the phase control set to 0
degrees.ꢀIfꢀtheꢀsoundꢀisꢀadequateꢀfromꢀtheꢀnormalꢀ

lacking bass, adjust the phase control until the bass
is full and punchy.
