Getting Started
Thank you for purchasing the Dual BAK1500 compact amplified subwoofer.
Although Dual has attempted to ensure the information in this manual is
accurate, please be aware that any part of it is subject to change without notice.
Please read entire manual before installation. Due to the technical nature of
amplifiers, it is highly recommended that your Dual BAK1500 is installed by a
professional installer or an authorized dealer.
Before You Start
•Alwaysdisconnectthenegativebatteryterminal.Consultaqualifiedtechnician
for instructions if you are unsure.
•Avoidinstallingtheamplifierwhereitwouldbesubjecttohightemperatures,
such as from direct sunlight, or where it would be subject to dust, dirt or
excessivevibration.
•Useextremecautionwhendrillingholestoavoiddamagingfuellinesor
existingvehiclewiring.
•Allamplifierinstallationsrequirepower,signalandspeakerwires(not
included).
•Anamplifierinstallationkit(soldseparately)ishighlyrecommendedto
facilitatetheinstallation.Consultyourdealerforrecommendations.
Mounting Location
•Foroptimumperformance,makesuretoprovideatleast1"ofspacearoundall
sides of the amplifier.
•DonotmounttheBAK1500undercarpetsorwhereairflowisrestricted.
•DonotinstalltheBAK1500whereitmaybeexposedtomoisture.
•Theoptimummountinglocationvariesbetweenvehicles.Remembertotestall
amplifier functions before completing the final mounting procedure.
PREPARATION

The following installation instructions are intended to be used as a basic
guideline. If you feel unsure about installing this speaker system yourself, Dual
recommendsacquiringtheservicesofaprofessionalcaraudioinstallation
center.
Beforeinstallation,pleasereviewthefollowingguidelines:
1. Be sure to carefully read and understand the instructions before attempting to
install this product.
2.Ifadditionalwiringisrequired,werecommendrunningallwirespriorto
mounting your enclosure in place.
3. To ensure reliable performance and minimize signal or power loss, use the
highestqualityconnectorsavailable.
4.Neverrunspeakerwiresunderneathyourvehicle.Runningspeakerwires
insidethevehicleprovidesthebestprotectionfromexhaust,heatand
environmentalelements.
5.Avoidrunningwiresover,nearorthroughsharp-edgedsurfaces.Wesuggest
you also use rubber grommets to protect any wires routed through metal,
especially the firewall.
6.Whenrunningthespeakercabletotheamplier,avoidrunningitnearsources
ofhighcurrent(i.e.wiringharnesses,batterycables).
Safety First
The following instructions are designed to ensure safety during installation and use

Note: Be sure to follow specific instructions included with your amplifier 
installation kit (not included with this amplifier). The information below should be 
used a general guideline only.
Power Wire (+12V)
•Disconnectnegativebatteryterminalbeforeproceeding.Consultaqualified

degrees.Ifthesoundisadequatefromthenormal
