About the Polk Audio PA1100.5
Polk Audio built their reputation by making some of the best speakers in the world. Now, they've extended their engineering expertise to their PA Series car amplifiers. These amps offer outstanding sound quality, high power, and a distinctive, stylish look.
The PA1100.5 5-channel amp delivers 80 watts RMS each to four speakers, plus up to 600 watts RMS to a subwoofer an all-in-one solution for powering your entire system. You'll find the variable high- and low-pass filters useful for tuning your system for maximum efficiency and sound quality, while the bass boosts on all 5 channels add an incredible amount of low-end punch when you need it.
The monoblock amp section of the PA1100.5 handles loads down to 1 ohm, giving you more flexibility in powering your subwoofer setup. The sub section also includes its own separate gain control, variable low-pass filter, selectable bass boost, and subsonic filter for ultimate low-frequency control.
An optional wired remote control lets you adjust your amp volume from the driver's seat. If you're into the show, a connector provides power for an optional external LED light array and fan, so your amp will run and look cool.

CEA-2006 Compliant: CEA-2006 is a new system of testing and 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 20,000 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 Polk Audio PA1100.5 under CEA-2006 regulations is rated at 80 Watts RMS x 4 channel and 280 watts x 1 channel with a 80dBA signal to noise ratio.
Tri-Way: The amplifier's 4-channels can be bridged down to 2-channels at 4-ohm. The amplifier is rated at 250 watts RMS x 2-channel at 4-ohms when bridged. The subwoofer channel remains 280 watts x 1.
1 and 2-Ohm Stable: The PA1100.5 features 2-ohm stable 4-channel operation and is capable of driving virtually almost any automotive speaker. The amplifier is rated at 125 watts RMS x 4-channel or 200 watts Peak x 4-channel with a 2-ohm load. The mono-subwoofer channel is 1-ohm stable and provides 600 watts of RMS power at 1-ohm.
Class D Amplifier: The Polk Audio PA1100.5 employs a super efficient Class D pulse-width modulation amplifier design. This type of amplifier design draws less power and runs cooler so you won't heat up the inside of your vehicle or make the headlights dim.
MOSFET Power Supply: The amplifier's high-speed MOSFET switching power supply and high current Bipolar Output Transistors pump maximum voltage and high current to your speakers or subwoofers.
Double Layer Fiberglass Epoxy Printed Circuit Boards: The amplifier employs double layer fiberglass epoxy printed circuit boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. This efficient layout packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.
6-Way Smart System Protection (SSP) Circuits: Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto-Standby Mode ensure safety, reliability and durability.
Status LED: The amplifier features a Status LED which will illuminate Green to indicate the amplifier is on and operating normally, and will be illuminated Red if the amplifier shuts down due to short circuit, DC offset, or overheating detected by onboard protection circuitry.
Aluminum Construction: The amplifier features an anodized extruded brushed-aluminum cover and textured end caps for maximum heat dissipation. The cast aluminum textured end caps optimize heat dissipation and hide and protect the amplifier's connections and controls. The end caps are removable to access the amplifier's connections. The amplifier also features a solid aluminum logo and model number panel which is back lit in cobalt blue.
Line Out Mode: The Line Out Mode allows you to configure the amplifier's mono-subwoofer channel as an input or line-output. When set to line-output mode, you can choose how the amplifier produces the line-output.
- SUM L/R: left front and rear and right front and rear channels are summed to produce the line-output
- Sub L+R: for use with an additional Polk Audio PA600.1 amplifier connected in Parallel mode
- Sub 180: for use when using an additional Polk Audio PA600.1 amplifier connected in External Bridge mode
Gain Control: The PA1100.5 features an independent gain control for the amplifier's Front, Rear and Subwoofer channels. The Gain Controls operate the amplifier's sensitivity for the front and rear channels and are used to match the input level of the amplifier to the output level of your signal source (headunit).
Crossovers: The amplifier features built-in 12 db/octave crossovers which can be set to High-pass, Low-pass or Flat for the Front and Rear channels. The mono-subwoofer channel is always set to Low-pass. The High-pass filter attenuates low frequencies and is used with mid-range speakers and tweeters. The Flat setting does not attenuate any frequencies and is for full range speaker systems. The Low-pass filter attenuates high frequencies and is used for subwoofers.
Crossover Frequency: The front and rear crossovers can be individually set between 50 to 500 Hz, while the mono-subwoofer Low-pass crossover can be set between 30-250Hz to fine tune your car audio system.
Bass EQs: The amplifier employs an independent 8 dB bass boost at 40Hz for added bass response for the Front, Rear and Subwoofer channels.
Subsonic Filter: The PA1100.5 utilizes a defeatable 24 dB/octave subsonic filter for the amplifier's subwoofer channels to eliminate very low frequencies below 30Hz that are difficult to reproduce, rob amplifier power, increase distortion and can damage speakers.
Remote Gain Knob: The PA1100.5 amplifier comes supplied with a wired remote gain knob which allows you to control the amplifier gain for the subwoofer channels only from a remote location in your vehicle for ease of adjustment during listening. The remote gain knob comes with a 16' cord which plugs into the back of the remote gain knob and the amplifier. The remote gain knob features integrated flanges and comes supplied with two philips-head screws for mounting the device. The remote gain knob measures 2.645" wide x 0.745" tall x 1.965" deep.
Power: The amplifier is equipped with a chrome-plated set-screw terminal for the power lead to connect through a fuse or circuit breaker to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery using a 8-gauge power wire (minimum). The power terminal will accept up to a 4-gauge power wire.
Ground: The amplifier is equipped with a chrome-plated set-screw terminal for the ground lead which connects directly to the sheet metal chassis of the vehicle using the shortest 8-gauge wire (minimum) necessary to make the connection. The ground terminal will accept up to a 4-gauge ground wire.
Remote Turn-On: The amplifier features a chrome-plated set-screw terminal for the remote turn-on lead which turns on the amplifier when 12-volt is applied to it. This terminal should be connected to the remote turn-on lead of your headunit or signal source. The remote turn-on terminal can accommodate up to an 8-gauge wire.
Speaker Terminals: Ten 0.3125" chrome-plated screw-terminals for connection to your full-range speakers and subwoofers using 16 to 12-gauge speaker wire.
Fuses: The amplifier features three 40-amp fuses to protect the amplifier against internal electrical damage. The amplifier comes with three inserted fuses and three spare fuses.
RCA Input Jacks: 3 pair of chrome-plated stereo RCA jacks which accepts the line-level output from your headunit or signal processor at voltages between 250mV and 8 Volts.
Note: One set of preamp inputs (subwoofer) can be used as an RCA output which allows you to send the input signal to a second amplifier in your system.
Remote: Remote input for supplied wired Remote Gain Knob.
LED/Fan Input: This input allows connection of an optional LED light bar or optional cooling fan for the amplifier using the supplied Power/Remote/Ground harness.
