the biggest woofer ever made no matter the price, the JackHammer will fi t into most full-sized SUVs and
some shorter models, like Escalades, with the third seat removed.
There are two versions of the JackHammer built for different applications. The SPL model (T9922-22) is
perfect for excessive bass and competition use, while the SQL model (T9922-44) offers increased sound
quality for “real life” listening. Both of these kits will work in the same motor for easy installation of either unit.
You can order either of these models or just a re-cone replacement kit for the other and switch between the
two without reinstalling the entire woofer. For more information, see the Piston Change (Re-cone Kit) section
in this manual or call 1-800-CALL-MTX.

ELECTRICAL UPGRADE
A factory electrical system will not be able to handle the power requirements of the amplifi ers 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 confi guration and supply the power needed and high-output
alternators from either Ohio Generator or PowerMaster. Also, it is recommended to use anywhere from 3 to 6
StreetWires capacitors to help control the fl ow of power, call 877.STREET1 for more information. The diagram
below shows the wiring needs of your entire vehicle. Please see the Strapping Thunder Amplifi ers section for
further information.
