Distributes the power for your whole system
This sweet-looking Kenwood Excelon X700-5 5-channel amplifier can power your entire system, serving 40 watts RMS each to four full-range speakers while delivering up to 500 watts RMS to your sub. Got a nice set of components up front? You can switch the amp over to 3-channel mode, driving your components with 100 watts a side while still giving a sub a healthy 500 watts RMS of power.

Tuning where you need it
High-pass filters on the front and rear channels let you tailor the sound to fit your vehicle and speakers. You can adjust the low-pass filter and a bass boost on the subwoofer channel to get just the right bass for your vehicle, while optimizing your sub's performance.

Cooling fan
The unique fin shape of the extruded aluminum heatsink helps pull heat away from the amp's interior, reducing distortion and extending the amp's life. An intelligent thermal management system continually monitors the temperature and turns on a cooling fan when necessary, saving your music from any interruptions due to overheating.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Product Research


Multi-Channel Design: The X700-5 is basically three amps built into one chassis, two full-range 2-channel amps (A and B), typically powering the front and rear speakers, and one mono amp to power a subwoofer. Either of the full-range amps can also be bridged to one channel.

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 plus noise (THD+N), 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 X700-5 is rated at 40 watts RMS x 4 plus 300 watts RMS x 1 with an 80 dBA signal to noise ratio.

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

  • Full-Range Channels:
    • 2Ω: 50 watts x 4 (at 1 kHz, no more than 0.5% THD)
    • Bridged: 100 watts x 2 (into 4Ω, at 100 Hz, no more than 0.5% THD)
  • Subwoofer Channel: 500 watts x 1-channel (into 2Ω, at 100 Hz, no more than 0.5% THD)
  • Signal to Noise Ratio: 100 dB (at rated power)

Cooling Fan: There is a cooling fan to help dissipate heat and ensure cool, reliable operation. Make sure not to block the vents or the fan when installing the amplifier.

Input Sensitivity: The X700-5 features independent gain controls for the front, rear, and subwoofer channels. The input sensitivity of each is adjustable from 200 mV to 5.0 volts.

High-Pass Filter: The front and rear amps have individual switches to set the built-in crossovers to high-pass or off (full-range). The crossover points are independently adjustable from 50-200 Hz. The high-pass crossover slope is 12 dB/octave.

Low-Pass Filter: The subwoofer channel's low-pass crossover is always engaged (it cannot be bypassed). The crossover point is adjustable from 50-200 Hz and the slope is 24 dB/octave.

Bass Boost: The subwoofer's bass boost circuit is centered at 40 Hz; boost is variable from 0 to +18 dB.

Aluminum Heat Sink: The aluminum heat sink increases the amplifier's heat dissipation efficiency, increasing the life of the amplifier.

Power And Ground Terminals: The amplifier features screw terminal power and ground terminals. They will accommodate spade connectors up to 0.55" wide.

Remote Turn-On Terminal: The remote turn-on is a screw terminal that will accommodate a spade connector up to 0.35" wide.

Speaker Terminals: The five pair of speaker terminals are screw terminals and will accommodate spade connectors up to 0.35" wide.

Signal Inputs: The amplifier features three pair of RCA input connections, A, B, and Sub.

Fuses: Two 40-amp ATO fuses are installed in the amplifier chassis.

Warranty Note: This refurbished Kenwood product carries a 90-day warranty when purchased from Crutchfield. Kenwood offers Crutchfield customers an extra 60 days extended warranty beyond the 30-day Kenwood Limited Warranty for Refurbished Product that comes in the box.

Crutchfield Customer Review (What's this?)

I bought a factory refurb...I'm super satisfied!!! Same great quality product without the price tag being so high. It pushes the system (2 sets of kicker components and 1 MTX thunderform 12). I was able to tuck it under my rear seat and it's outta sight and outta mind.

Pros: Plenty of power!

Cons: N/a

Great amp for the price, delivers plenty of sound. Paired with a 4 ohm JL 10" in my Durango can be tuned from the head unit I choose to have balanced highs, mid's, and low's or can be cranked up to make your neighbors talk about you when you come in from work each day..

Pros: Great powerful sound!

Awesome !

Crutchfield Customer Review (What's this?)

I was upgrading the equipment in my civic and came across this amp... I couldn't afford the alpine pdx series since I wanted an amp that powered everything... For the price I couldnt pass it up... Got it the next week and had it professionally installed.... Couple days later it made a Loud horrible thumping sound when I turned my head unit on, then I smelled something burning.... Saw smoke coming from it... Crutchfield was excellent an had another one 4 days later.... Never had a problem since..... Powers everything to the max.... I can't turn the volume passed 28 and it goes to 35!

Pros: Excellent amp for the price Plenty of power for the speaker set up Easy to fine tune Very small

Cons: Not any that I can think of

Great amp

This amp is small and easy to mount. Pushing 2 pair of 6x9. In the doors and a pair of alpine e 10' inch in a down fire box. Very clean power and the gains are easy to understand. It pushes the tens to the limit and they hit hard, even in the downfire box

Pros: Easy to install and small enough to mount under seat

Cons: Nne right now

Great product

Crutchfield Customer Review (What's this?)

i wired this in conjunction with a Audio Control LC6i Line Output Converter in order to keep my factory radio. it is awesome!

Pros: 5 channels, built in cross overs, easy to set up.

Cons: no high inputs. you need a set of RCA cables for each channel (front, rear and subwoofer).

When using this amp for only 3 channels you could use the front and rear pair of RCA's and bridge the outputs to increase power to your front 2 channels and use the sub output for the sub. [ CLYDE  Jun 23, 2014 ]
i would use the front rca jacks and the sub rca jacks. i have mine hooked up to 5 speakers and it is a great amp. [ WILLIAM  Jun 23, 2014 ]
You will want three sets of RCAs. Left, right, sub. Left and right each include front and rear. [ Robert  Jun 23, 2014 ]
