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.
Overview: The Dual DPA250 is a 2-channel, Class AB amplifier, designed
to drive a pair of full-range speakers, or a subwoofer. It produces 35 watts RMS
x 2 at 4 ohms, 50 watts RMS x 2 at 2 ohms, and 100 watts RMS x 1 at 4 ohms
bridged. The amp's extruded aluminum heatsink helps keep the amp running cool.
CEA 2006 Compliant: The DPA250's power ratings are measured
according to standards provided 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.
LED Indicators: The amplifier is equipped with two
side-mounted LED indicators:
- Power LED: illuminates green when the unit is turned on
- Protect LED: illuminates red if a short circuit or
thermal overload is detected. The amplifier will automatically shut down if
this occurs. Once the amplifier becomes sufficiently cool, the amp will
Low-pass Filter: The DPA250 is equipped with a variable low-pass
filter that can be adjusted from 50Hz to 300Hz. It has a slope of 12dB/octave. A
2-way switch lets you set the amp for low-pass or full-range operation.
Bass Boost: Using the 3-way switch, you can apply a bass boost to the
output of +6dB or +12dB. The bass boost is centered at 45Hz. If no bass boost is
desired, the switch can be set to 0dB.
Treble Boost: In addition to the bass boost, the amp offers a 3-way
switch for applying a treble boost to the output of +6dB or +12dB. The treble
boost is centered at 5kHz. If no treble boost is desired, the switch can be set
Screw Terminals: The power, ground, remote turn-on, and speaker
connections are terminal strips, which can be tightened or loosened using a
Phillips or flat screwdriver. Spade lugs should be used on the wires, as the
terminal openings are narrow slots. It is recommended that you use a 10AWG
amplifier wiring kit. The remote turn-on lead and the speaker terminals can
accept up to 12AWG wire.
