MOUNTING
Mounting the TS9924-22 JackHammer is nothing that can be taken lightly, quite literally. You need to follow the
steps below carefully and have all the necessary equipment. You will need to be able to lift the nearly 400 lbs.
subwoofer comfortably. MTX Audio recommends a fork lift or engine hoist for safe installation.
The woofer is designed to distribute its weight evenly throughout the entire structure. This is accomplished by
including rear motor mounts with
5
⁄
8
"-11 bolts so it is mounted from both the front and the back. It is important
that both these sides are mounted properly to ensure proper weight distribution. The drawing above shows the
rear mounting hole detail for the back support. The holes are located on an 8
5
⁄
8
" bolt circle, meaning the holes
are located on a radius of 4
5
⁄
16
" from the center point. Use the pallet from the JackHammer packaging to make a
mounting template if needed. For the recommended 1" baffl e, the bolts needed should be
5
⁄
8
"-11 threaded bolts
1
3
⁄
4
" long. Washers should be used with the
5
⁄
8
"-11 bolts to be sure there will be no air leaks around the bolts.
In the gasket of the woofer, there are four eyelet rings. Make sure they are screwed in securely before attaching
a chain between them for lifting. Use one tine of the fork lift to lift the JackHammer with the chain then slowly
lower it into the enclosure. Unscrew the eyelets and align the woofer with the front and rear mounting holes,
and then fasten it using the screws and bolts provided. Remember to pre-drill the screw holes using a
5
⁄
32
" drill
bit. Then, lift the enclosure, complete with JackHammer, into the back of the vehicle.
Note: This unit is EXTREMELY heavy! Make sure everyone is clear and out of the way in case something
should break or fall!
Note: MTX Audio is not responsible for damages occurred during installation. For custom installation help
or answers to further questions, please call 1-800-CALL-MTX.
Warning: Prolonged exposure to high sound levels can lead to permanent hearing loss. In addition,
drastically over powering speakers can result in extreme heat which could cause a fi re. For your own
safety and enjoyment, please follow the manufacturer’s power handling recommendations.
Warning: Sudden stops or auto accidents may cause speakers to dislodge and become projectiles.
Securely fasten all audio components to the car’s structure to prevent property damage or serious personal
injury.

WIRING OPTIONS
Often overlooked, the installation components used to connect the entire system need to match the maximum
capability of the system or you will lose performance. MTX Audio recommends using StreetWires 4 AWG cable
as the speaker wire.
Dual Voice Coil Wiring
TS9924-22 JackHammer Superwoofers are available in a dual 2 Ohm voice coil confi guration. The voice coils
are labeled VC1 and VC2.
Note: Both voice coils should always be connected.
Independent Voice Coil Connection Confi guration
This connection is ideal when using two large mono block amplifi ers per voice coil.
Parallel Confi guration
Wiring the voice coils in a parallel confi guration will have a total fi nal load of 1 Ohm. Connect each of the dual
voice coil’s positive terminals together so that they share the same source (amplifi er). Do the same for the
negative terminals. This connection is ideal when using a large 1 Ohm stable amplifi er.
Note: The wiring of the dual voice coils will affect impedance for the amplifi er system. Care must be
taken to assure that the resulting impedance does not exceed the amplifi er’s requirements.
Series Confi guration
Wiring the voice coils in a series confi guration will have a total fi nal load of 4 Ohms.
