Product Details

Kicker DX250.1 DX Series 250W Class D Mono Car Audio Subwoofer Amplifier

If your amplifier isn't FIT, what good is it?

Kicker DX Series amplifiers provide the utmost reliability from the biggest name in trouble-free amplification and loud, clear sound. All Kicker DX amplifiers feature FIT™ (Fail-Safe Integration Technology) to kill the noise created by the alternator, computer, and audio/video entertainment components found in vehicles today.

FIT's isolated differential inputs reject noise and electrical interference for the quietest operation possible and ultimate audio clarity. Differential inputs also make Kicker amps compatible with any factory or aftermarket radio. Stereo RCA pass-thru outputs make daisy-chaining amplifiers simple.

A muting circuit cancels out additional noise that may surge down the line, so listeners enjoy the cleanest, clearest sound possible. Additionally, a choice of three automatic turn-on modes—remote, DC offset, and signal sense—provides ultimate flexibility.

Kicker Certified Power!

Kicker's DX Series DX250.1 mono subwoofer amplifier is factory tested and certified to provide at least (and in many cases, more than) 250 watts RMS per channel into a 2 ohm load. Each amplifier includes its own serialized test certificate that documents how much power it can actually put out. Not only is this amplifier powerful, the efficient Class D topology keeps the amplifier footprint small.

Tweak Your System!

9 dB of boost (centered at 40 Hz) is switchable to add in extra bass to suit your taste. Turn on the available -24 dB/octave, fixed, 25 Hz subsonic filter to prevent harmful ultra-low frequency content from damaging your ported subwoofers. The built-in, fixed 80 Hz, 24 dB/octave low-pass filter keeps the mids and highs out of your subwoofer's operating range.

• Kicker certified power output:
            140 watts x 1 (@ 14.4V, 4Ω, ≤1% THD+N)
            250 watts x 1 (@ 14.4V, 2Ω, ≤1% THD+N)
• Frequency response: 20 to 200 Hz (±1 dB)
• Input sensitivity:
            Low level: 125 mV to 5V
            High level: 250 mV to 10V
• Signal-to-noise ratio: >95 dB (A-weighted at rated power output)
• Crossover (switchable):
            LO (fixed): 80 Hz, -24 dB/octave low-pass
• Fixed bass boost (switchable): 9 dB @ 40 Hz
• Dimensions (L x W x H): 10-1/4" x 8-5/16" x 2-1/4"

Also available in the DX Series of Kicker amplifiers is the 125 watt DX125.2 stereo amp, 200 watt DX200.4 four-channel amp, 400 watt DX400.4 four-channel amp, 600 watt DX600.5  five-channel amp, 250 watt DX250.1 mono amp, 500 watt DX500.1 mono amp, and the 1,000 watt DX1000.1 mono amp.

I would like to connect tweeters to the kicker but the tweeters dont sound I know the tweeters are good how can I connect?

This amplifier is designed for subwoofer use only with a fixed low pass filter that cannot be switched off. This is why you are not hearing high frequencies.

can I use this apm to work my speaker for voice ??????

Asked by: crock718
This amplifier has a very limited frequency range up to only 200 Hz, so this is only designed for use with subwoofers.

can I bridge the 250.1 with one dual voicesz coil sub and which terminals I hook to ?

Asked by: arizonaoneforme
This is a mono amplifier so it only has one set of terminals to wire to. It is also 2 ohm stable, as long as your woofer has dual 4 ohm coils you can use this amplifier with it.
