OWNER'S MANUAL AND
INSTALLATION GUIDE
INTRODUCTION
Your new LINEAR POWER™ amplifier employs a sophisticated design
combining reliability, high power, low distortion, and freedom from external noise.
When properly installed, it will give long and faithful service. When combined with
other high quality components, it will be the heart of a superb system.
1001SW TECHNICAL DESCRIPTION
The Model 1001SW©is a dedicated subwoofer amplifier with a built-in variable
crossover. This unit is 2 ohm or 4 ohm capable, delivering 100 watts of power
into a 4-ohm load and 200 watts into a 2-ohm load.
The unregulated pulse width modulated driven power supply of the 1001SW©
uses mosfet switching transistors for high current capacity and improved
efficiency. Over current and thermal protection circuitry are used to insure long
life and reliable operation. The speaker output is also internally fused to protect
against any mishaps that might occur in wiring or under extreme loading
conditions.
The amplifier section of the 1001SW©utilizes an all-discrete design to insure low
noise and distortion levels. The output transistors are capable of producing high
currents, yet only operate at a fraction of their full rating.
The 12dB/octave crossover is switchable between 60,80 and 110Hz, with high
pass outputs for use in multi-amp systems. The gain control is infinitely variable
which permits optimal signal matching for lowest noise and lowest distortion with
virtually any source.

INSTRUCTIONS
Read the following instructions through completely. If they appear too
complicated, we recommend that you have an authorized LINEAR POWER™
Dealer perform the installation.
WIRING
1.Disconnect battery ground cable before making any power connections.
2.BLACK WIRE - Connect this wire to a clean, unpainted metal surface in the
car.
3.RED WIRE - Connect this wire to the battery's positive (+) terminal. A fuse
should be installed within 18 inches of the battery connection and another fuse
where the connection to the amplifier is made. Remember, use the proper size
fuses. The 1001SW©uses a 25-amp fuse.
WARNING: USING OVERSIZED FUSES IS DANGEROUS AND WILL
DAMAGE YOUR AMPLIFIER.
4. RED AND WHITE WIRE - is connected to the radio's "turn on lead" or power
antenna remote lead. When neither of these exists you may connect this lead to
a +12 Volt wire that is on when the car ignition is on or in accessory position.
5. RCA (phono) JACKS - The 1001SW©has 2 sets, one marked INPUT and the
second marked HIGH PASS OUT. The first set will accommodate either high or
low level signals. If possible use good quality shielded cable for low-level inputs.
For high-level inputs solder low power speaker wires to RCA connectors with the
center pin as positive.
The second set of RCA jacks marked HIGH PASS OUT are for use with a
second amplifier used to run midrange and treble speakers without the need for
an external active crossover. (See crossover selection for more information).
6. SPEAKER CONNECTION - Insert speaker wires into plug positive (+) to the
left slot and negative (-) to right slot. The 1001SW©is rated at 4 ohms and is
capable of operating into 2 ohms minimum (do not use less than a 2 ohm load
as this will cause amplifier failure and damage your amplifier).

OPERATION AND ADJUSTMENT
CROSSOVER SELECTION:
Remove plug on bottom of amplifier and select frequency, which sounds best
with your system by placing the switch at one of the 3 positions marked 60Hz,
80Hz or 110Hz. This also sets the high pass output frequency. When this is
accomplished, replace plug.
GAIN ADJUSTMENT:
Set the amp gain to minimum, turn the source up until it just starts to distort, then
back down slightly. This is the point where the output of the source is cleanest.
Now, bring the gain of the amp up until it just starts to distort and back it down
slightly. This will allow the source and amp to reach maximum usable output at
the same time.
MOUNTING
1. The amplifier will work best if it is kept as cool as possible. Mount in a position
that allows air to flow freely through the fins. Be sure there is ample space above
the amplifier to avoid trapping heated air rising from the amplifier. The amplifier
should not be mounted upside down. Avoid mounting any amplifier in the dash or
on the firewall to avoid noises being radiated directly into the case.
2. Mount your amplifier in a position that allows ample room for gain adjustments,
and the installation, removal and attachment of leads.
3. The case of your amplifier is designed to act as a noise shield. To maintain
this protection, be sure the metal case of the amp does not touch the metal of the
car. Do not remove or damage the rubber grommets, which provide electrical
insulation and vibration isolation.
OPERATION/ADJUSTMENT
The output of most any car audio equipment will follow a common distortion
curve. This curve will show that the distortion is at its lowest level right before the
amp reaches full rated output. After that point, the distortion increases rapidly to
unusable levels. For any system to operate at minimum distortion with minimum
noise and still reach full power output, the equipment should be aligned to
operate at the same point on the curve at the same time.

In a basic system, using a single amplifier, set the amp gain to minimum, turn the
source unit up until it just starts to distort, then back down slightly. This is the
point where the output of the source is cleanest. Now, bring the gain of the amp
up until it just starts to distort and back down slightly. This will allow the source
and amp to reach maximum usable output at the same time.
GENERAL TROUBLESHOOTING
NO SOUND
Check all connections. Check main power fuse. Check accessory fuse of your
vehicle. Check to see that +12Vdc is present at the amplifier on the power wire,
and on the red/white remote turn-on wire. Check for a solid ground connection.
Check that the main music source is putting out signal.
BLOWS FUSES
check all connections to be sure no wires are touching each other or the chassis
of the vehicle or any other equipment in your install. Check that your speakers
are in proper working order.
SHUTS OFF
As this amplifier is equipped with thermal and short circuit shut-down electronics,
in the event of high ambient temperature or improper speaker impedances, the
amp will turn itself off. To avoid damage to speakers, turn down the volume while
waiting for the amp to turn itself back on. If this occurs repeatedly, use a fan to
cool the amplifier and check for proper speaker loads and connections.
