ElECTRICAl UPGRADE
A factory electrical system will not be able to handle the power requirements of the amplifiers that are
needed to drive the JackHammer. You will need to upgrade your vehicle’s electrical system with both
additional batteries and alternators. MTX Audio recommends West Co. SVR80 or SVR100 because they are
a sealed battery that can be mounted in any configuration and supply the power needed. Also high-output
alternators from either Ohio Generator or PowerMaster. It is recommended to use anywhere from 3 to 6
StreetWires capacitors to help control the flow of power, call 877.STREET1 for more information. The diagram
below shows the wiring needs of your entire vehicle. Please see the Strapping Thunder Amplifiers section for
further information.
