About the Kenwood Excelon X301-4

You'll get big power out of this small box

The 4-channel Kenwood Excelon X301-4 amplifier can dish out 50 watts RMS each to four speakers, yet still fit almost anywhere in your vehicle. For applications that require more power, you can bridge the amp to 2-channel mode to drive a pair of speakers or components with 150 watts RMS each. In 3-channel mode, you can use the amp's front channels to drive a pair of speakers with 50 watts each, and bridge the rear channels to send 150 watts to a sub..

Fine-tuning included

High-and low-pass filters let you optimize the sound for your vehicle and speakers. When you're running a subwoofer with the rear channels, you can adjust a bass boost to get just the right thump to fit your musical tastes.

Convenient technology

Class D technology ensures that this compact amp will run cool and perform reliably. The X301-4 accepts input signals via RCA cables from an aftermarket receiver or by way of your vehicle's speaker wires, so it will work with almost any mobile audio system. If you use the speaker-level inputs, the amp can sense the signal and turn itself on, so you won't need to run a separate remote turn-on lead to the receiver.

Excellent value.

Derek from Sullivan, IN on 8/5/2018

Verified employee purchase (What's this?)

I've had many many amps over the years but never had a Kenwood, anything! I think the price did it for me. I bought it scratch and dent but found neither on the amp itself. Really it fit my budget build perfectly as well as under my front seat! It has clean class D power, so far has not failed me and well get fairly loud. It certainly brings out the best in my Alpine sps 610c fronts and Alpine sps 510 rears.

Pros: Class D, small footprint, Excelon warranty and PRICE!

Cons: None so far

I am using this with with four 6.5 inch Infinity Kappas in a Silverado and a Kenwood Head Unit. I like the clarity at louder volumes. It will get loud with no distortion. Small size is nice for mounting.

Not enough power

Dennis from Peoria, AZ on 5/16/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I got this for a Camaro Boston Acoustics amp bypass and it has very little power to run the factory BA speakers. This amp is worse than the factory amp. It is just too under-powered. It gets hot and it cuts out at times only pushing 4 factory car speakers. I do have everything maxed out, or I can't even get a full range of sound. This will only power the rear 6X9's with decent sound quality. I had to purchase a second 300 watt amp, which did 100% better, but I decided to let this weak amp run the 6X9's, or throw it in the trash. I can't think of anything else to use it for. The Kicker is way better for full range of sound and seems to have much more power. My Kenwood 1000W is pounding my 12" subs. This little amp can't pair up with such weak power.

Pros: Small. Good connectors

Cons: Weak, distorts easily, cuts out, runs hot, not 2-Ohm stable bridged. Only 4 Ohm stable bridged. No great cost savings for what you get. Will only push 2 6X9's effectively in a Camaro with the SubThump BA amp bypass.

Great sound and full range of controls from a fairly compact amp. Running JBL GT7 series speakers front and rear on a 2016 Colorado. All I could ask for at a geat price.

Pros: compact size, full adjustability

Cons: none yet

Compact, small foot print

Ray from Wichita, KS on 12/11/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a nice amp. It's compact and has plenty of power/volume. However I expected it to have a little more base and kick on the lower end of the volume. The X301-4 is driving four Kenwood KFC-C6895PS speakers. The head unit is a Kenwood Excelon KDC-X998 using the pre amp outputs. Overall the sound is clean and crisp and the power is there if you so desire to crank up the volume.

Pros: Small, Compact, well designed. Good power output.

Cons: None really to speak of...

Product Research

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and over a frequency range of 20 Hz to 20 kHz, when applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Kenwood X301-4 is rated at 50 Watts RMS x 4 channels with an 80 dBA signal to noise ratio.

Specifications: The manual also lists these non CEA-2006 compliant specifications:

  • Power: 75 watts x 4 channel (into 2Ω, at 1 kHz, no more than 1.0% THD, 14.4 volts)
  • Frequency Response: 20Hz - 50kHz (+0, -3dB)
  • Signal to Noise Ratio: 100 dB (at rated power)

Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is the amplifier runs more efficiently, generating less heat than Class AB amps. The Class D design also allows the amplifier to be built on a small chassis, and installed where space is limited.

Signal Sensing: The amplifier has a signal-sensing turn-on circuit. When a signal is detected on the inputs, the amplifier will automatically power on. When the signal is no longer detected, the amp will shut off. This allows you to install the amplifier without a remote turn-on lead.

Controls: The X301-4 features independent controls for the front channels (1+2) and rear channels (3+4). The following controls can be found on the end of the amp:

  • Input Sensitivity: The Input Sensitivity controls let you match the amplifier to the preamp output level of the source unit. The rotary control lets you adjust the sensitivity between 200mV (0.2V) and 5V, with markings at 0.2V, 0.3V, 0.5V, 1V, 2V, 3V, 4V, and 5V. (The input will also accept a speaker-level input signal between 4V and 12V.)
  • Selectable Crossovers: The amp has 3-way switches to let you configure the channel pairs to high-pass, low-pass, or full range (crossover off). The rotary controls adjust the crossover frequency between 50Hz and 200Hz, with markings at 50Hz, 80Hz, 100Hz, 150Hz, and 200Hz.
  • Bass Boost: The Bass Boost increases the bass signal, centered at 40Hz. The rotary control lets you adjust the boost between 0dB and18 dB, with markings at 0dB, 1dB, 3dB, 5dB, 8dB, 12dB, and 18dB.

Connections:

  • Line In: The X301-4 has two pairs of RCA inputs for connecting the amp to the source unit via an RCA cable. The amp will accept a low-level signal between 200mV and 5V. It will also accept a speaker level input between 4V and 12V. For a speaker level input, the source unit's speaker wires will need to be spliced onto RCA plugs, or use a third-party speaker-to-RCA adapter.
  • Power/Ground/Remote Turn-on: The amplifier has screw-down terminals for the power, ground, and remote turn-on, and will accommodate spade connectors. The power and ground terminals are 0.55" wide, while the remote turn-on terminal is 0.33" wide.
  • Speaker Output: Four pairs of screw terminals are provided for connecting the speakers. The terminals are 0.33" wide, and accommodate spade connectors. The amplifier is designed for a 4Ω load, but can can handle a load impedance of 2Ω to 8Ω. The amplifier can be bridged to a 4Ω-8Ω load.
  • Fuses: Two 20A ATO fuses are installed in the amplifier. With the 40A fuse rating, an 8-gauge amplifier wiring kit is recommended with a 40A fuse installed within 18" of the battery.

Q
Could I bridge Polk MM 651 speakers to this amp? The speakers are rated at 2.7 ohm, but says its compatible with 4 ohm. Thinking of getting two of these for my Harley and using 1 for the front speakers and the other for the rear speakers. This would result in the amp driving the speakers at 150 watts per channel. Any issues with this setup? I would like to get some more clear sound at higher speeds on the Harley (70 to 80 mph).

For details on your installation, you would be better served reaching out to an Advisor directly by phone (1-800-324-9695) or online chat. They can go over all the options with you as far as installation and compatibility with the Polk speakers and Kenwood amplifier, and recommend the necessary items to complete the install. I hope that helps!
