Can you say "1000 watts for under $250?" The "Class T" design of Clarion's DPX1000.2 amplifier means more power with less heat in a smaller chassis — and that means cleaner sound and more mounting options. Plus, it's stable down to 1 ohm in stereo mode, which allows for a variety of speaker applications. Bridge this silver beast to mono operation, and it'll drive two 4-ohm subs with 1,000 watts of clean power!

The DPX1000.2 is packed with features, too. The variable low-pass crossover and subsonic filter give you a lot of sound-tweaking control. When setting the crossover, you can choose from a 12 or 24 dB per octave slope to get a cut-off that blends with the mid-range frequencies, or a sharp bass-only roadblock. The selectable subsonic filter removes power-robbing extreme low bass for greater amp and speaker efficiency.

You can dial in the perfect amount of low-frequency punch with the adjustable bass boost (0-15 dB at 45 Hz). Adjust the power level from the driver's seat with the wired remote gain control. Use this versatile amp in full-range mode for your main speakers, or low-pass mode for your subs.

Important Note: A 4-gauge amp wiring kit alone is not sufficient for installing this amplifier. A 100-amp ANL hi-amp fuse and a hi-amp fuse holder are also needed. See "Wiring Recommendations" under the Detailed Info tab for more information.

Class T Amplifier Design: Class "T" digital amplifier design combines the high fidelity sound reproduction of class "AB" amplifiers with the low heat dissipation benefits typically found in class "D" amplifiers. Although class "D" amplifiers generate little heat, they are almost exclusively used as subwoofer amps, because they are not known for high fidelity, full range sound reproduction. Class "AB" amplifiers generate much more heat than class "T" and class "D" amplifiers, so large heat sinks are needed for cooling. The class "T" design allows this amplifier to be made smaller than class "AB" amplifiers of a similar power rating, without the sound quality sacrifice that comes with a class "D" design.

Input Select Switch: This switch allows you to select between stereo, single-input bridged, or L+R (left plus right) bridged.  The benefit of the single-input bridged mode is that it allows single-channel RCA input to be used for bridged applications.  This is useful in high-powered systems when using one amplifier for each subwoofer where your receiver has limited RCA outputs. 

Crossover Slope Switch: This switch allows you to select between a 12dB and 24dB crossover slope.  Selecting the 24dB slope when driving subwoofers will better keep out midrange tones, which will make the amplifier more efficient.

Subsonic Filter: This switch activates the subsonic filter circuit, which eliminates unwanted frequencies from 24Hz and below.

Crossover: This amplifier includes a continuously variable 55-550 Hz low-pass crossover.  You can opt to engage the low-pass crossover, or it may be turned off for full-range operation.

Remote Sub Level Control: There is a port on this amplifier for the supplied remote sub level control.  This control allows you to adjust the output level of the amplifier from a remote location, like your driver's seat.

Protection Circuitry:

  • Over current: shuts off the amp when the input signal is too high
  • Offset: shuts off the amp when the output voltage is too high
  • Thermal: shuts off the amp when the operating temperature is too high

Controls and Indicators


  • Crossover frequency control: a rotary control that sets the crossover cut off frequency from 55 to 550Hz
  • Crossover slope: a push-button switch that allows you to select between a 12dB and 24dB crossover slope
  • Bass boost control: a rotary control used to set the bass boost from 0 to +15dB at 45 Hz
  • Gain control: a rotary control used to set the amplifier's input sensitivity to match the level of the incoming signal
  • Subsonic Filter: a push-button switch used to engage the subsonic filter circuit 
  • Output Select Switch: let's you select between full-range and low-pass operation
  • Input Select Switch: let's you select between stereo, mono, or right input only bridged modes


  • Power LED: illuminates green when the unit is on
  • One Ohm Mode LED: illuminates light green when operating at 1-ohm

Inputs and Outputs


  • +12V (power): screw terminal (0.50" wide)
  • GND (ground): screw terminal (0.50" wide)
  • REM (remote turn-on): screw terminal (0.375" wide)
  • Speaker-level inputs: These provide a high-level connection option from your receiver. Note: When using the included harness for the speaker level inputs, the black wire must be grounded at the radio.
  • Line-In: set of stereo RCA jacks
  • Remote Level Control Port: phone-style jack for use with supplied remote Sub Level Control (BC2). 


  • Speaker outputs: screw terminals (0.375" wide)

Amplifier Fuse Replacement: Note that the three 30-amp fuses in this amplifier are internal, so the bottom cover of the amplifier will need to be removed in order to access them.



  • RMS power at 4 ohms: 250 watts x 2 (at <1% THD)
  • RMS power at 2 ohms: 450 watts x 2 (at <1% THD)
  • RMS power at 1 ohm: 500 watts x 2
  • RMS power when bridged (2 ohms): 1000 watts x 1 (at <1% THD)
  • Preamp input voltage: 250mV - 2.5V
  • Maximum current consumption (at 1000 watts): 86 A

Wiring Recommendations

Wiring Recommendations: This amplifier uses three 30-amp fuses, so its fuse rating (90-amps total) exceeds that of typical 4 gauge wiring kits, which tend to include a 60-amp fuse. For 90-amp fuse protection, an ANL wafer style fuse is required, but none of the 4-gauge wiring kits include a ANL-style fuse holder. Since pre-packaged amplifier wiring kits cannot be used alone, you may purchase all the necessary items separately, or you may use a pre-packaged 4 gauge wiring kit along with a ANL-style fuse holder and a 100-amp ANL wafer fuse (a 90-amp fuse is not available). If you do not use a wiring kit with the necessary additional items, the separate parts and wiring needed to install this amplifier are as follows:

  • 1 ANL wafer-style fuse holder capable of accepting 4 gauge wire
  • One 100-amp ANL wafer fuse
  • 2 power rings for 4 gauge cable
  • 4 gauge power cable (to connect the battery to a fuse holder and the fuse holder to the amplifier)
  • 4 gauge ground cable 
  • Remote turn-on cable (speaker wire can be used as remote turn-on cable)
  • 1 stereo RCA patch cables
  • Speaker wire
