Efficient power supplies offer quick response, while the die-cast aluminum heatsinks incorporated into the black casing keep the amp running cooler for extended life.

Add the XiA3145 to your aftermarket stereo with preamp connections, or hook up to your factory radio with the speaker-level inputs. Variable frequency filters send the right signals to your speakers to keep them from reaching for sounds they can't reproduce. A variable bass boost adds extra fullness to the low notes when you need it.

This amplifier also includes connections to power up the Illuminite™ LED system in select Dual speakers and subs, giving your system and ride a cool blue glow.

Features

Overview: The Dual XIA3145 two-channel amplifier is designed to power a set of full-range or component speakers. The amplifier can also be bridged to power a single subwoofer. The amplifier features a Class AB output design, MOSFET power supply, and Die-cast aluminum heatsink for good sound, efficiency and dependability.

CEA 2006 Compliant: The Dual XIA3145's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.

  • Two-Channel (4-ohm): 100 watts RMS x 2-channels in 4-ohms at 20-20,000Hz with 1% THD
  • Two-Channel (2-ohm): 145 watts RMS x 2-channel in 2-ohms at 20-20,000Hz with 1% THD
  • Bridged (4-ohm): 290 watts RMS x 1-channel in 4-ohms at 20-20,000Hz with 1% THD
  • Max Output: 290 watts Peak x 2-channel in 4-ohms

Protection Circuits: The amplifier features three protection circuits to protect the amplifier.

  • Thermal overload protection
  • Auto-reset speaker short circuit protection
  • Reverse polarity protection

LED Indicator: The LED indicator illuminates green during normal operation (Power) and red when the amplifier detects a fault (Protect).

IllumiNite: The amplifier features a 4-pin connector for connecting Dual illumiNite subwoofer enclosures (sold separately). The lightning elements of Dual illumiNite subwoofer enclosures provide you with a unique custom touch to your vehicle's car stereo system. Dual's patent pending illumiNite LED system and control circuitry provides an extraordinary blue-hue illumination which allows great creative opportunities for the beginner or seasoned customer installer.

Mounting: The amplifier can be mounted horizontally or vertically. For optimum performance, make sure to provide at least 1" of space around all sides of the amplifier. The amplifier cannot be mounted upside down.

Cover Plate: The amplifier's recessed side-mounted controls and connections are hidden under a removable cover-plate. To access the amplifier's controls and connections, you must review the cover-plate by unscrewing 4 hex-head machine screws using the supplied hex-key.

Controls

Input Level Control: The input level control (gain) is used to obtain the best possible match between your connected headunit's audio output and the amplifier input. The amplifier's gain control has a low level input range of 200mV-6V and a high level input range of 2V-10V.

Crossovers: The amplifier features a Crossover Switch which allows you to select Full-Range, High-Pass, or Low-Pass.

  • Full-Range: The full-range setting allows all frequencies (20-20kHz) to pass through the amplifier from your connected headunit to your connected speakers.
  • High-Pass: The high-pass setting is variable and allows only frequencies above 40-400Hz to pass through the amplifier to your speakers.
  • Low-Pass: The low-pass setting is variable and allows only frequencies below 40-400Hz to pass through the amplifier to your speakers.

Bass Boost: This control provides additional boost (0-12dB) for your connected subwoofers at 45Hz.

Connections

+12V Power Terminal: The amplifier features a +12V power set-screw terminal which accepts up to an 8 AWG power wire. The +12V wire must be fused within 18" of the battery for protection of your vehicle's electrical system.

Ground Terminal: The amplifier features a set-screw ground terminal which will accept up to an 8 AWG ground wire. The amplifier's ground wire should be kept as short as possible and connected to a clean unpainted section of metal or the vehicle chassis.

Remote Turn-On Terminal: The amplifier features a set-screw remote turn-on lead terminal which will accept up to an 8 AWG wire. The remote turn-on wire connects to the head unit's amplifier turn-on lead or power antenna output.

Speaker Outputs: The four speaker terminals (left +/- and right +/-) are set-screw-terminals that will accommodate up to 8 AWG speaker wire.

Speaker Input: The amplifier comes with a two channel speaker level input harness. Once you splice the speaker wires from the receiver to the harness, you have plug-in convenience to the amplifier. This feature makes it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs.

RCA Inputs: The industry standard RCA jacks provide an easy connection for signal level input.

IllumiNite Circuit: 4-pin plug used to connect the supplied 4-pin power/ground harness.

Fuse: The amplifier features two 20-amp main ATO fuses and one 2-amp "illumiNITE" ATO fuse. The amplifier also comes supplied with two spare 20-amp ATO fuses and one spare 2-amp ATO fuse.
