Axxera even includes a wired remote control that lets you adjust your subwoofer level from the driver's seat.

Features

Channel Configuration: The Axxera AX550D is a 5-channel amp; essentially two full range 2-channel amps and one mono subwoofer amp built into one chassis. Both full range sections are bridgeable, so the it can be configured as a 5-channel, 4-channel, or 3-channel amplifier.

  • Channels 1/2 and 3/4:
    • 4Ω: 56 watts RMS x 4-channels
    • 2Ω: 79 watts RMS x 4-channels
    • Bridged: 154 watts RMS x 2-channels into 4Ω
  • Channel 5:
    • 2Ω: 400 watts RMS x 1-channel

Signal Inputs: Both RCA harnesses and speaker level harnesses are included to plug into the three input ports on the amp.

Auto Turn-on: When using a speaker level input, the amp will turn on automatically when it senses the input signal.

Controls

Level Control (Gain): The input levels are independently adjustable for channels 1/2, 3/4, and 5. The input range is 0.5 Volts to 12.0 Volts.

Crossover: The amp has independent crossover controls for channels 1/2, 3/4, and 5. The crossover slopes are all 12 dB/octave:

  • Channels 1/2:
    • Mode: two position switch; choose flat (full range, crossover is bypassed) or high pass
    • Frequency: set the crossover point when in high pass mode; rotary dial; 35-250 Hz
  • Channels 3/4:
    • Mode: two position switch; choose flat (full range, crossover is bypassed) or high pass
    • Frequency: set the crossover point when in high pass mode; rotary dial; 35-250 Hz
  • Channel 5: because the channel 5 is the subwoofer section, the low pass crossover is always engaged
    • Frequency: set the low pass crossover point; rotary dial; 35-250 Hz

Bass Boost: The bass boost on channel 5, centered at 45 Hz, is continuously variable from 0 dB (flat) to +12 dB.

Wired Remote: A wired subwoofer level control is included (channel 5 only). The remote has integrated flanges and screws are included to mount the unit under the dash. It includes a 15' cable to connect to the amplifier.

Note: The wired remote measures approximately 1-5/8" wide (2-1/4" including the mounting flanges) x 1" tall x 1-5/8" deep (2-1/4" including the knob and cable).

Connections

Power Input: Two set-screw terminals are provided for connecting the power and ground cables. The terminals accept up to 8-gauge wire. The set screws are tightened/loosened with a Phillips head screw driver (not included).

Speaker Outputs: The five pair of speaker output set-screw terminals will accept up to 8-gauge wire. The set screws are tightened/loosened with a Phillips head screw driver (not included).

Signal Input: The amplifier has three proprietary signal input jacks, for use with either the included RCA harnesses or the included speaker level harnesses.

Remote: The wired remote cable plugs into another proprietary jack on the amp. The remote turn-on wire is also found in this harness.

Fuse: The amp has one 40-amp ATO fuse.

A
The wired remote bass control is not sold separately. If you have this amplifier and need a replacement, you may be able to get one from the manufacturer: 866-382-5476 I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5
