Alpine KTA-200M Power Pack

Features

Overview: The Alpine KTA-200M is a Power Pack series mono amplifier that can deliver up to 200W of RMS power to a single mono output (4-ohm or 2-ohm), in a compact form that allows it to be mounted just about anywhere.

Dynamic Peak Power (DPP): The KTA-200M has a high-efficiency Class D digital circuit design that uses Alpine's exclusive Dynamic Peak Power technology. This allows the amp to deliver bursts of power for peak demands, providing up to 100% more dynamic power when needed. The amp can provide up to 200W RMS into a 4-ohm or 2-ohm load.

Mounting: Two types of mounting brackets are included with the amp, plus four zip ties. The first mounting bracket is designed to mount the amp to the back of Alpine's iLX-W650, iLX-W670, or iLX-407 digital multimedia receiver. The iLX-W650 is just over 2¾" deep by itself, so even with the added depth of the amp (totaling just over 5"), the combination fits in almost any dash with a Double DIN opening. The bracket also leaves a gap of approximately ¾" between the amp and head unit, so most of the wiring can be routed to that space. The second option is a pair of universal brackets that bolt to the ends of the amp, and provide a mounting flange with four screw holes. The chassis of the amp also has four tabs, through which the included zip ties can be looped to attach the amp behind the dash.

Controls:

• Gain: A single rotary control adjusts the RCA input level, with a range of 0.2V to 4.0V.
• Low Pass Crossover: Two DIP switches let you apply a low pass filter to the signal, with selections of 60Hz, 80Hz, 120Hz, or Off (full range).

Harness: All the wiring for power, input, and output is in one harness. The wires in the harness are one foot long and it plugs into a recessed area on the amp, with openings on the side and bottom, so the wires can be routed in either direction.

Power/Ground/Remote: The power and ground wires in the harness are 14-gauge (each having two 16-gauge wires from the harness, merging to a single 14-gauge wire). The power wire should be extended and connected directly to the battery, using an in-line 20-amp fuse (sold separately) near the battery terminal. An 18AWG blue/white remote turn-on wire will need to be connected to your radio's remote output lead, or connected to vehicle switched power to activate the amplifier.

Signal Inputs: There are two male RCA plugs on the included harness for pre-amp level inputs. If your source unit has no pre-amp outputs, a speaker-level to RCA converter will be required (sold separately).

Speaker Output: The harness includes 2 wires for the mono speaker output (each comprised of 4 wires from the harness merged into one wire).

• Brown: Positive (+) speaker output.
• Brown/Black: Negative (-) speaker output.

Remote Bass Knob (Optional): The KTA-200M includes an RJ-14 input jack on the main harness, for use with the optional Alpine RUX-KNOB.2 remote bass level control (sold separately). This allows you to easily adjust the subwoofer volume from the driver's seat, independently from the main speakers.
