Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Overview: The C 245BEE is a flexible 4-channel amplifier, divided into two discrete 2-channel amps in one chassis (A and B). Each side is individually bridgeable, so it can be used to power four speakers, three speakers, or two speakers.

Discrete Inputs: The A and B channels have separate inputs; both also have Loop Through outputs for connecting another amplifier. The output is identical to the corresponding input.

Auto Turn-on: The C 245BEE can be turned on automatically one of two ways; +12 volt trigger from another component or by sensing an input signal. The automatic function can also be turned off so the amp is turned on/off manually using the front panel switch.

Controls

Rear Panel:

• Bridge Mode: switch between stereo and mono amplifier output; the A and B channels have individual mode switches
• Power: master power switch
• +12V/Input Sensing: choose +12 volt trigger or signal sensing to automatically turn the amp on

Connections

Rear Panel:

• Speakers: the speaker binding posts will accept single banana plugs, pin connectors, spade lugs up to 0.45" wide, and bare wire up to 12 gauge; there are four speaker outputs, A (left and right) and B (left and right)
• Signal Inputs: two sets of stereo RCA inputs, A channels and B channels
• Line Outputs: two sets of stereo RCA inputs, A channels and B channels; output is identical to the corresponding input
• 12 Volt Trigger: 3.5mm jack; turn the amp on/off along with another device that has a +12 volt trigger output
• AC Input: 2-pole IEC power input for use with included cord (or optional upgraded cord)
