Our take on the Sony XM-N502 by Crutchfield's Buck Pomerantz
Sony delivers the sound
Bored with your vehicle's sound system? Sony's XM-N502 2-channel amplifier will add clarity and power to your system, delivering 65 watts RMS to each of your speakers, so you'll have more fun listening to music on the road. To add some low-frequency fun, you can bridge the MX-N502 amp into 1-channel mode and drive a subwoofer with 175 watts.
A low-pass filter helps your sub sound its best. Sony placed all of the MX-N502's connections and controls on the front of the amp, for a cleaner installation with easier access to adjustments. To protect the amp from overheating and shutting down, an Auto Thermal Control lowers the power output slightly during those moments of extreme, hard driving play. Sony shows its commitment to high quality by gold-plating this amp's connectors for reliable conductivity.
XM-N502 connection and control panel
Works great, was a replacement for an older unit so install was simple. I use it to power my subs and works perfect. Good size to fit in trunk in tight space behind sub enclosure. Would definitely recommend

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 measuring 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 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare amplifiers on an equal basis. Using CEA-2006 criteria, the Sony XM-N502 is rated at 65 watts RMS x 2 channels, with a 93 dBA signal to noise ratio.
Pulse Power Supply: The amplifier utilizes a Pulse Power Supply system to regulate the fluctuating voltage received from the car's electrical system.
LPF: A two position switch turns the low pass filter (LPF) on/off, the crossover point is fixed at 80 Hz and the slope is 18 dB/octave.
Power Connections: The power, ground, and remote turn-on screw terminals are 0.35" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. A protective cover is included for the power/ground/remote terminal block.
Speaker Connections: The speaker screw terminals are 0.35" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals.
RCA Input: The amplifier features one pair of stereo RCA line level inputs (left/right).
Fuse: The amp is protected by a single 25-amp ATO blade fuse.

Why did you buy this?
Decent price [ Jeffrey May 24, 2017 ]
Positive reviews and Sony's reputation. I use to use a lot of Sony produces in video production and always had a good experience. [ Eddie May 23, 2017 ]
This was a simple replacement for a Boston Acoustics GTA 602 that gave up the ghost after being locked in a trunk in the Florida heat for 7 years. Specs are similar and I'm not being overly choosy now that my car has broken in and has significant road and wind noise. [ David May 21, 2017 ]
Close in size and peek power as the one I have in my other vehicle. I hope that it preforms as well. [ Anthony May 14, 2017 ]
Closest Replacement For Old Unit [ Charles May 11, 2017 ]
Great value for what i need. [ Donald Apr 28, 2017 ]
I needed to replace an old Eclipse power amp. The Sony's inputs and speaker hookups are in a similar location, so the wiring will just swap over. The original installation had two of the Eclipse amps. I have already replaced one with the Sony amp. The Sony provides a clean, pleasing sound. [ David Feb 18, 2017 ]
I chose the Sony XM-N502 strictly because it was an Open Box unit and at a very reasonable price point. I have a history dating back more than 30 years with the Sony brand and have confidence the amplifier will meet my general need for amplification in a low wattage application. [ Patrick Feb 17, 2017 ]
Seems like a good value, and I respect Sony's good reputation for quality. [ Peter Jan 26, 2017 ]
good amp at a great price [ NERY Dec 30, 2016 ]
Sony is my preference when it comes to brand [ german Nov 26, 2016 ]
Will be my second one. Compact and I like the connections on one side of the amp. Great price [ J Gregory Nov 23, 2016 ]
to get the full use of new speakers, more power is needed. [ Roy Nov 22, 2016 ]
Good signal to noise ratio [ Chris Nov 13, 2016 ]
I purchased all the components for my truck stereo back in 1997. I still drive the truck with the sound system. The amp that powered the sub woofer finally gave out. I needed a replacement amp. [ Edmund J. Nov 13, 2016 ]
7 questions already asked
The Sony XM-N502 does require a remote turn-on lead for installation. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps! [ Larry Nov 20, 2016 ] Staff
From my understanding, it is designed to run the left and right channel in stereo (2-channel) or bridged mono (1-channel), not both modes at the same time. If you had a dual voice coil subwoofer, you could run the left and right channel to the sub instead of running in bridges mode. I think this is what you are implying. Either way, make sure you match the ohms of how you wire to your speaker impedance. [ JEFF J Nov 16, 2016 ]
I checked the manual and it does allow it. You need to install a cap inline with the main speakers and a coil inline with the sub. Depending on the crossover freq you want will depend on the values of the cap and coil. It shows the connections in the manual. [ J Gregory Nov 15, 2016 ]
No. This amp isn't made to do that. [ JOSEPH Nov 15, 2016 ]
Since this is a 2 channel amp, you can run 2 speakers in stereo mode OR bridge the 2 channels to run 1 mono channel. You can't do both. You would need a 4 channel amp to do that. [ eric Nov 14, 2016 ]
Tom, I hope this answer your question. MAX. CHANNEL CONFIGURATION AT 4 OHM (W) / THD (%) 65 W x 2 / 1.0% MAX. CHANNEL CONFIGURATION AT 2 OHM (W) / THD (%) 85 W x 2 / 1.0% Maximum Output Power (1 kHz) MAX. CHANNEL POWER CONFIGURATION AT 4 OHM 2 x 150 W MAX. CHANNEL CONFIGURATION AT 4 OHM BTL 1 x 500 W MAX. CHANNEL POWER CONFIGURATION AT 2 OHM 2 x 210 W [ JOSEPH Sep 16, 2016 ]
A lot of company's list their amps with power levels that really are not realistic but they still do it. If you drill down in the specs it does list 1x500watts at 4ohms BTL all done at 1khz. So yes it will give 500 watts but it's at one frequency level and probably more distortion than you could handle. Look at RMS power at 1% THD. That's the true power that is meaningful. It took me awhile to find the "500" listed as well. With that said the amp works great for my 2 10" subs in my 66 mustang. One thing that sold it for me was all connections are on one side of the amp so all cables come from one location. [ J Gregory Sep 13, 2016 ]
The 500W power that they mention is peak power into a 1 ohm load in bridged configuration. However, it's more than just peak, but is actually peak-to-peak, which takes into consideration the entire voltage/current waveform of a sinewave from the highest positive-going voltage to the lowest negative-going voltage. Their specs mention a bridged RMS power of 175W into a 1 ohm load. To get the peak power, simply multiply this figure by 1.414 (the square root of 2). So 175 X 1.414 = 247.45Wpk. To get peak-to-peak, multiply by 2, which gives 247.45 X 2 = 494.9Wpk-pk. Round up the answer, and you've got an attractive advertisement. Frankly, RMS power gives a better indication of what to expect in performance. [ Michael Sep 12, 2016 ]
Probably at max distortion, not totally horrid on sub duty, but not realistic of course.... Perhaps right before the fuse is blown. Into 2 ohm, dipping lower? Anyway 165 bridged at 4 ohms is probably about the max clean power [ Kenneth Sep 12, 2016 ]
The 65 watts per channel is the rms rated power @ 4 ohms which means that the amp can put out 65 continuous watts per channel at a Total Harmonic Distortion (THD) of 1% or less. This amp can accept a 2 ohm load and put out higher wattage. It can also be bridged (combining both channels to make a single channel). In this configuration, the amp puts out 175 watts rms @ 2ohms. The 500 watt figure is the peak power output in bridged mode. Peak power output on any amp will sound very distorted when the wattage exceeds rms rated output as THD increases exponentially above it.

The difference is max or peak power vs. RMS. When shopping for head units or amps, I only pay attention to RMS specs. RMS specs are the best ones to use when comparing different products and matching watts to your speakers. When considering speakers, you must pay attention to ohm specs also. [ JEFF J Sep 12, 2016 ]
Yes [ LEONARDO M Jan 12, 2016 ]
I forwarded your question to an Advisor and they responded with the following: There is no need to use wire that big with this amp, but you can use it as long as you put a terminal on the end of the wire. I don't expect the amp's inputs to take wire that big. By the way, that's a good match on this amp with those speakers! If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Aug 17, 2015 ] Staff
