Power a sub wherever you go

Kenwood's KAC-M3001 compact mono subwoofer amplifier will power the bass in your vehicle with up to 300 watts RMS. That's enough to hear the bass clearly above the noise of the road, trail, or waterway as you travel along. This little powerhouse will fit almost anywhere, including a storage compartment on a boat, motorcycle, or ATV, so you can put great bass in whatever vehicle you wish.

Weather-resistant protection for music on the go

Conformal coating protects the internal circuits from water and dirt, so the show will always go on, even through the roughest conditions. The subwoofer output terminal features a plastic-covered plug that provides further protection for the connection.

High-level inputs ease installation

The KAC-M3001 will accept a signal from just about any source, whether you're using RCA cables from an aftermarket receiver or speaker wires from a factory radio. When you use the speaker-level inputs, the amplifier will sense the signal and turn itself on, so you won't need to run a remote turn-on lead to your car stereo.

Features

Compact Amplifier: The Kenwood KAC-M3001 compact Class D mono block amplifier is designed to drive a subwoofer (or two). The amp features a conformal coating on the circuit board to protect it from moisture. This allows you to use the amp for motorcycles, marine applications, or on All-Terrain Vehicles (ATVs). The KAC-M3001 delivers 200 watts RMS x 1 channel at 4 ohms. It also gives you 300 watts RMS x 1 at 2 ohms.

Protection Circuitry: The amplifier features protection circuitry for thermal overload, DC offset, and short circuits. The amp stops operating when it goes into protection mode. (There are no LED indicators.)

Signal-sensing Turn-on: When the amplifier is connected to a factory head unit, or an aftermarket unit without preamp outputs, you can splice the head unit's speaker wires to a speaker-to-male RCA adapter. In this case, the amplifier's Signal-sensing Turn-on feature will turn on the amp when a signal is detected on the input. This eliminates the need to connect a turn-on lead to the amp's Power Control (blue) wire.

Crossover: The amp has a low-pass crossover to filter out the high frequencies that a subwoofer is unable to reproduce. The crossover has a continuously variable crossover point (50 to 200 Hz) with a slope of 24dB/octave. The crossover cannot be turned off.

Mounting: The KAC-M3001 can be mounted onto an installation board (5/8" thick or more) using the supplied M4 x 16mm self-tapping screws. Two 13.5" plastic wire ties are included for securing the amplifier to a 2x4 board or other narrow item.

Connections

Power/Power Control Connections: The power, ground, and power control connections are 0.35" wide screw terminals. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors or ring terminals are recommended. A minimum 10-gauge wire is required for power and ground.

Power Control: The Power Control wire should be connected to the head unit's remote turn-on lead when an aftermarket unit is used. This wire does not need to be connected if you're using speaker level inputs. The Signal-sensing Turn-on feature will turn on the amplifier when an input signal is detected.

Line-Level Inputs: The amplifier is equipped with a pair of RCA inputs for connecting a stereo RCA patch cable from the head unit to the amp. If using a factory head unit, or a unit without preamp outputs, you can splice the speaker wires to an RCA plug, maintaining the same polarity.

Speaker Outputs: The included speaker output harness has four 16-gauge wires for connecting your speakers to the amp. The two positive and two negative wires are each soldered together to produce a single positive and a single negative output. You can connect a single 4-ohm or 2-ohm sub directly to the amplifier. Two 4-ohm subs wired in parallel or two 2-ohm subs wired in series can also be connected. Speaker wiring diagrams for each configuration are printed in the included Installation Guide.

What gauge are the speaker output wires?

peter Mar 06, 2025

1 answer

Greetings Peter. Thank you for your question. The speaker output harness has 16 gauge wire.

thomas Mar 06, 2025 (Staff)

How much power can the speaker level inputs take? It says to use a bare wire to RCA adapter but the specs only say the input sensitivity is from 0.2V-5V. I want to tap into my factory subwoofer signal which is rated for 40W RMS.

tony Sep 11, 2023

1 answer

I think this is no cause for concern, Tony. Kenwood does not list the wattage maximum on the speaker level inputs, so there is no way to determine an exact spec. If you notice any sort of clipping or bad sound, you can always add the LC2i Pro in the link below to process and control the voltage output of your subwoofer signal. https://www.crutchfield.com/p_161LC2IPRO/AudioControl-LC2i-PRO.html

Good morning, I have a question before I order... could this amp power 4 Polk DB 692 speakers (for my motorcycle)? Thank you!

scott Sep 16, 2020

It can but doesn't sound very good. I have a fosgate 400 watt for four speakers on my street glide and it can be heard at highway speeds however, a larger amp would be ideal.

dial ray Oct 07, 2020

Is this amp 1ohm stable? I am looking to power subs that have dual 1 ohm voicecoils.

aaron Dec 06, 2019

Hi Aaron, thank you for your question. The Kenwood KAC-M3001 is not 1ohm stable. Chat with an Advisor online or by phone at 1-800-324-9695. We will be happy to help you find an amp that can safely and effectively drive your subs.

jessica Dec 31, 2019 (Staff)

Amp is too small to run 2 subs at 1ohms.

dial ray Dec 31, 2019

Could this theoretically power 6 speakers, 2 sets of 3, each set wired in parralel, then both sets wired together in series, connected to the amp in bridged mode. The load impedance would be 2.67 and 300 watts RMS w/ 600 peak from the speakers. The amp says it can handle a load impedance of 2 ohms?

carlos Nov 26, 2017

1 answer

I didn't quite follow your wiring description there Carlos. I can tell you this is a mono (single channel) amplifier so, no; it cannot be bridged (as that requires 2 channels). Assuming you were able to wire the 6 subwoofers to present an acceptable impedance (It's certainly possible depending on the number and impedance of each woofer's voice coils) you would get no more than 50 watts RMS per sub.

i burned up a kicker subwoofer 43CWRT672 voice coil in my jeep tj center console with this amplifier KAC-M3001 wired in series for 4 ohms. i plan on replacing the subwoofer. is this kicker speaker not rated for this amp or could i wire up the replacement differently so i don't burn it up in 1 day?

Thanks for your question. For information on selecting the best amp/sub combo I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the different models and help you make the best choice for your system.

kenneth Sep 01, 2017 (Staff)

can this amp be ran at 1 ohm?

cody Sep 30, 2015

1 answer

2 ohm, but not sure about 1ohm. In any case this amp runs my 8" Kicker Marine sub very well with no problems!

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
