Check to make sure you have a good ground connection.
Check that there is at least 12v on the battery (+) terminal
Check that the Remote Input (Turn-On) has at least 10VDC.
Check that the green power LED is lit
Check all fuse, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then Power Cycle (reset).
A.POWER STATUS LED
AUTO POWER CIRCUIT
The AUTO POWER circuit is for high level
(speaker-level) connections. When the speaker
level connections are used AND the remote
turn on wire is NOT used the subwoofer will
AUTO POWER ON when signal is detected.
If the amplifier detected no signal input, the
amplifier will auto turn off.
You MUST use the Remote Control as this is
used to set up level and See G on its functions
B.REMOTE LEVEL CONTROL PORT
.
C.HIGH LEVEL (speaker level) INPUTS
If your head unit does not have RCA outputs
you can use the speaker outputs for the audio
source for the subwoofer. Use the supplied
cable and wire harness and connect the
outputs properly as shown in the connection
diagram in this manual (FIG2, PG5)
There is a GREEN “power” LED that glows
green when power is on and no problems are
present. If the protection circuit (PRO) comes
on, it will illuminate the other LED RED
F.FUSE
Do not use a fuse with a different value
and NEVER replace the fuse with a wire
or coin. The fuse is there to protect the vehicle
NOT the amplifer/subwoofer.
Note: Please connect the remote terminal
to the remote output of head unit as in
Fig.4. When you hear the unit turn ON/OFF
there should be a very slight POP noise
from the subwoofer.

Features/Functions
E.POWER INPUT TERMINAL
Use 8 guage COPPER wire!! NOT CCA type
cheap-o deluxe wire kits!!!!
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.
Check that the RCA grounds are not shorted to the vehicle chassis
Check that the head unit is properly grounded.
D.LOW LEVEL RCA INPUTS
Low level inputs are the recommended way
to introduce the audio signal to the subwoofer.
IF RCA outputs are present on your head unit
or other signal source (such as a sound
processor - see FIG 1, PG4).
NOTE: NEVER CONNECT BOTH RCA AND
SPEAKER INPUTS SIMUALTANEOUSLY!!

Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk
or hatchback installations will require a 15-20 foot RCA cable, Always use a high
quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!
SPECIAL NOTE: Always route power and signal seperately
POWER AND INPUT SIGNAL WIRING
NOTE: DO NOT USE CCA wiring kits
EVER!!!!! Using this type of wire VOIDS
your warranty!
1. Connect your 8 guage power wire
DIRECTLY to the battery B+ terminal
with a high quality ring terminal. Make
sure that a fuse holder is approx. 18
inches from the battery and the fuse
should be NO larger than 20 amperes.
2. Make sure to run the power wire thru a
gromment in the firewall to eliminate any
possiblitity of shorts.
3. Route the Remote Control cable (phone
wire) thru your vehicle to the sparetire
area of you trunk.
4. Connect a remote turn on wire to your
head units remote output using 16
gauge blue wire (not included)
SPECIAL NOTE:
The VPAS12ST is equipped with an
automatic turn on circuit if NO
switched 12 volts is available for
turn-on.

SPARE TIRE
SPARE TIRE
This is a VERY simple install and can fit into virtually any car made in the last 10 years.
WITHOUT removing your spare tire. Follow the instructions to a SUPER easy install!
1. Remove the trunk liner. Typically it is NOT screwed or bolted down. It should
simple pull out as shown below in Figure 1
TRUNK LINER
2. Once the trunk liner is removed and you can get access to your spare tire
Make a mental note if the spare tire is deep side down or deep side up???
Deep Side Down Deep Side Up

FLIP OVER THE SPARE TIRE - IF NEEDED
1. IF your spare tire is Deep
Side UP then you need to
unbolt it and flip it over so
the VPAS12ST can sit
inside of it.
(See Figure 2)
2. IF your spare tire is Deep
Side DOWN then you simply
need to unbolt the sparetire
and drop the VPAS12ST in so
it can sit inside of it.
(See Figure 3)
NO NEED TO FLIP OVER THE SPARE TIRE
2. Make sure to check
what size the mounting
bolt is as the VPAS12ST
comes with a 8mm and
a 10mm mounting bolt.
Which should fit 90% of
all vehicles out today.
8mm or 10mm Mounting Bolt

SPARE TIRE WITH ABS NUT (AUDI/VW TYPICALLY)
Some vehicles have a different type of spare tire mounting system as shown below.
Where there is a large “NUT” and a bolt coming thru the center of the spare tire.
IF so....
1. Thorughly clean the spare tire
2. Replace the original spare ABS fixing nut with the supplied one that came with
the VPAS12ST
ORIGINAL OEM ABS NUT

REPLACEMENT ABS NUT
(included)
CONNECTING WIRING HARNESS
1. The VPAS12ST should be mounted into
the spare tire area at this point.
2. Remove the M6 hex screws from the
below the handle/port area as shown
to the left (Figure 5) Insert Power/Input
plug assembly. Make sure to push until
it “clicks” into the locked position .
3. Once the Power/Input plug is securly
plugged in, replace the handle/port cover
With the same hex screws. Tie-Wrap all
wiring so it is clean and easy to remove
the VPAS12ST subwoofer when the time
arises.

SetUp
J.PHASE SWITCH
Use this switch to help compensate for time
alignment problems in the system. Such
problems usually result from having the
subwoofer at a different distance from the
listener than the other speakers in the system.
G.INPUT GAIN CONTROL
After you have installed your system, turn this
GAIN control to minimum (counter-clockwise).
Turn the head unit on and adjust the head unit
volume to a comfortable listening level.
Slowly turn up the subwoofer input gain control
until you hear a small amount of distortion. Then
reduce the level until the distortion is completely
gone. Leave the control at this setting.
H.BASS BOOST
The BASS BOOST feature will increase the
sound level in the bass frequencies.
I.LOW PASS FILTER (LPF)
This control permits you to define the frequency
range you want the subwoofer amplifier to
receive. The subwoofer will reproduce all sound
BELOW the frequency you set.
Note: The low pass filter frequency can be higher or lower
than the marked Frequency by as much as +/- 20% tolerance

SYMPTOM POSSIBLE REMEDY
Check to make sure you have a good ground connection.
Check that there is at least 12v on the battery (+) terminal
Check that the Remote Input (Turn-On) has at least 10VDC.
Check that the green power LED is lit
Check all fuse, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then Power Cycle (reset).
Turn down the volume control on the head unit to prevent overdriving
the input speaker leads,
Try Power cycling (reset) the amplifier. If the Protection LED still comes
on, then the amplifier is faulty and needs servicing

Troubleshooting
Check that all fuses are OK.
Check that the power light in on
Check that unit is properly grounded.
Check that the Remote Input (Turn-On) has at least 10VDC.
Check that the input signal connections are plugged in properly.
Readjust the Input Gain Control.
Check the Crossover Control settings, possibly try a higher frequency.
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.
Reset Input Gain. It is best to set the subwoofers 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 subwoofer input level as low as possible.
Check for improperly grounded RCA interconnects. Or possible “blown”
signal ground from headunit. (Some headunits are notorious for this!)
Check that the Input Gain control is set to match the signal level of the
head unit. Always try to set the Input Gain on the subwoofer as low
possible. Input gain is NOT power output!! Check that all crossover
frequencies are properly set.
Readjust the Input Gain Control.
Make sure to NOT use CCA power wire as it will cause these issues
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.
Check that the RCA grounds are not shorted to the vehicle chassis
Check that the head unit is properly grounded.
