Features

Overview: The Alpine HDA-F60 4-channel amplifier is effectively two full range 2-channel amps built into one chassis, labeled Channel 1/2 and Channel 3/4. Each section of the amp is bridgeable, so it can be wired as 4-channel, 3-channel, or 2-channel. It is stable down to 2Ω in stereo, and 4Ω when bridged.

Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is the amplifier runs more efficiently, generating less heat than Class AB amps.

Power Specifications:

• 4Ω: 100 watts RMS x 4
• 2Ω: 150 watts RMS x 4
• Bridged: 300 watts RMS x 2

Ultra-Wide Frequency Response: The Alpine HDA-F60 offers a super-wide, frequency range for unparalleled sound quality and detail:

• +0/-3 dB (1W into 4Ω): 10 Hz - 60 kHz
• +0/-1 dB (1W into 4Ω): 15 Hz - 30 kHz

Hidden Controls: All the amplifier's audio controls are hidden under a removable top panel:

• Channel 3/4 Input: 2-position switch; choose 1/2 (the channel 1/2 inputs are copied to channels 3/4), 3/4 (dedicated front and rear inputs)
• Gain: independent rotary gain controls for the front (1/2) and rear (3/4) channels
• Crossovers: separate, identical crossover controls for the front and rear channels
  • Filter: 3-position switch; high pass/low pass/off (full range)
  • Frequency: rotary control; variable from 50 Hz to 400 Hz; 12 dB/octave slope

Optional Remote Bass Control: The amplifier has an RJ-25 modular jack for adding an optional wired remote (RUX-KNOB.2, sold separately) to control the output level of channels 3/4. The remote has a 20dB adjustment range.

Terminal Layout: For wiring convenience, all of the inputs and outputs on the amplifier are on one side.

Quick Connect Plugs: The Alpine Status series amplifiers use quick connect plugs to attach your system's speaker wires and power cables to the amp for a simple, error-free installation. The quick connect plugs have set screw terminals that are tightened/loosened using the supplied hex wrenches. The power, ground, and remote turn-on connections are made to a single quick connect plug. The power and ground terminals will accept up to 4-gauge (recommended) wire, while the remote terminal will accept up to 12-gauge. There are two quick connect plugs for connecting the front and rear speaker wires. The speaker terminals also accept up to 12-gauge wire.

Audio Input: There are two pair of RCA jacks for connecting low-level or high-level input signals. If connecting the source unit's speaker wire to the input jacks, you can use a Speaker-to-RCA adapter or splice an RCA plug onto the speaker wire. When using a high-level input signal, it may not be necessary to connect a remote turn-on lead because of the amplifier's remote sensing function.

Input Level: There is a 2-position switch to choose the input level range for the RCA inputs; High (500 mV-10 V) or Low (200 mV-4 V).

Fuses: The amp is equipped with two 35-amp ATO fuses; a 70-amp (minimum) external fuse should be placed on the +12V power wire within 18" of the battery.
