Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
CEA-2006 Compliant: CEA-2006 is
a new system of testing & measurement methods for mobile audio amplifiers. This
voluntary standard advocates a uniform method for determining an amplifier's RMS
power output and signal-to-noise ratio. The criteria for measuring power uses a
DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm
load, with 1% or less Total Harmonic Distortion (THD) plus noise, and at a
frequency range of 20 Hz to 200 Hz, when applicable. Signal-to-Noise ratio is
measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4
ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an
equal basis. The Infinity Reference 1300a under CEA-2006 regulations is rated at
200 Watts RMS x 1 channel with a 85dBA signal to noise ratio.
Mono-Power Amp Design: The
Infinity Reference 1300a is designed with specific features to power your
subwoofers with a frequency range between 11-330 Hz. This amplifier is not
designed to power a full-range speaker.
Class D Design: The Infinity
Reference 1300a is equipped with a high-performance Class D switching power supply,
which is more efficient than traditional class AB power supplies, and draws less
current from your vehicle's charging system.
Protection Circuitry: The amp
features 4-way protection, and will shut itself down in the following cases:
- DC Output: DC voltage is
detected on the amplifier output
- Temperature: Amplifier is
- Over/Under Voltage: Voltage at the +12V (Battery) terminal is less than 8.5V or more than 16V
- Short Circuit: Short
circuit in speaker or speaker wire
Power and Protection LEDs: The amplifier
features a Power and Protection LED on top of the unit. The Power LED
illuminates Green when the amplifier is supplied power. The Protection LED will
illuminate Red when the amplifier goes into protect-mode.
Input Level: Rotary
control to match the level of the preamp input signal
Low Pass Filter: The 1300a has a
variable 12dB per octave, 32-320Hz low pass filter to prevent unwanted
high-frequencies from reaching your subwoofers so they can play deeper and
Bass Boost: The Bass Boost
control allows you to enhance the bass output of your system at 50Hz up to 6dB.
Optional Remote Level Control: The amp
has an RJ-11 jack for use with the optional remote sub-level control
module. The control module includes a 19.5' cable to connect the
remote to the amplifier. This sub-level controller allows the subwoofer level to be adjusted from the listening
Preamp Output: 1 pair of
gold-plated RCA jacks (amp provides a non-filtered signal for daisy-chaining
Preamp Input: 1 pair of gold-plated RCA jacks.
Remote Level Control:
RJ-11 jack for use with the optional remote sub-level control.
IMS Input: This port is
designed for future Infinity expansion products.
Speaker Output: 4 Set
screw terminals for connecting speaker wires; handles up to 8 gauge (16
gauge minimum recommended).
Note: There are two
sets of terminals to make it easier to connect multiple subwoofers. The
terminals are connected internally in parallel.
- +12V: Set screw
terminal for power wire from battery; handles up to 4 gauge wire (8
gauge minimum recommended)
- Remote: Set screw
terminal for remote turn-on lead; handles up to 8 gauge wire (18 gauge
- Ground: Set screw terminal for ground;
handles up to 4 gauge wire (8 gauge minimum recommended)
Fuses: 3 Slots for 20A ATO
