1. Find a suitable location in the vehicle

in which to mount the amplifier. A

typical location is shown below:

2. Make sure there is sufficient air

circulation around the intended

mounting location.

3. Mark the location for the mounting

hole screws by positioning the cabinet

where you wish to install it. Make a

small mark to identify the position and

remove the unit.

Thoroughly clean the area you plan to

attach the subwoofer, using a vacuum

cleaner.

Then attach the supplied double

adhesive tape, and put the subwoofer

in the place and press down on it

securely.

Mounting the subwoofer

If you experience operation or performance problems with this product, compare your

installation with the electrical wiring diagram on the previous pages. If problems persist,

read the following troubleshooting tips which may help eliminate the problems.

Low-level (RCA) input wiring is preferred for best audio performance. Most trunk

or hatchback installations will require a 15-20 foot RCA cable, while pickup trucks

and under-seat installations will require a 6-12 foot RCA cable. Always use a high-

quality cable.

Protection LED

comes on when

amplifier is

powered up.

Check for short circuits on speaker leads.

Turn down the volume control on the head unit to prevent overdriving.

Remove speaker leads, and reset the amplifier. If the Protection LED still

comes on, then the amplifier is faulty and needs servicing.

High hiss in the

sound.

Disconnect all RCA inputs to the power sub’s control panel. If the hiss

disappears, then plug in the component driving the amplifier and unplug

its inputs. If the hiss disappears at this point, go on until the faulty/noisy

component is found.

It is best to set the amplifier's input level control as low as possible. The

best subjective signal-to-noise ratio is achieved in this manner. Try to

set the head unit as high as possible (without distortion) and the amp

input level as low as possible.

Squealing noise

is present.

Check for improperly grounded RCA interconnects.

Distorted sound.

Check that the Input Level Control is set to match the signal level of the

head unit. Always try to set the Input Level as low as possible.

Check that all crossover frequencies are properly set.

Check for short circuits on the speaker leads.

Amplifier gets

very hot.

Check that the minimum speaker impedance for the amp model is correct.

Check that there is good air circulation around the amp. In some

applications, it may be necessary to add and external cooling fan.

Engine noise

(static type)

This is usually caused by poor quality RCA cables,which can pick up

radiated noise. Use only the best quality cables, and route them away

from power cables.

Engine noise

(alternator

whine)

Check that the RCA grounds are not shorted to the vehicle chassis.

Check that the head unit is properly grounded.

5. Connect all line inputs and outputs (if

used) using high-quality cables. Connect

all speakers, following the diagrams in

this manual. Be sure to observe proper

polarity to avoid audio phase problems.

6. Insert a 30A fuse into the battery fuse

holder.

7. Recheck all connections before

powering up the subwoofer.

8. Set all level controls to minimum

position, and set all crossover

controls/switches to the desired

frequency points.

9. Power up the head unit and the

subwoofer. Then set the volume control

on the head unit to about 3/4 volume,

and adjust the subwoofer's input level

controls to just below the level of

distortion.

10. Further fine tuning of the various

controls may be necessary to obtain best

results.

Vehicle seat

Connect the ground terminal to the closest point on the chassis of the vehicle.

Keep this ground wire to less than 39" (100 cm) in length. Use 8 gauge (or heavier)

wire.

Connect the remote terminal to the remote output of the head unit using 16 gauge

(or heavier) wire.

Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 8 gauge

(or heavier) cable from this fuse to the amplifier location. Then connect the fuse

holder to the "BATT+" connection on the subwoofer rear panel.

Install the remote control securely under the

dash or in a similar location where using it will

not distract the driver.
