Sony XM-604M

The XM-604M amplifiers afford incredible installation flexibility and packs quite a punch. ZR amplifiers offer tremendous value including convenience features such as: modern cosmetics, selectable cross-overs, multiple channel configurations and singe-side electrical connections to suit almost any application; such applications also include cars and other non-marine installs. Whether the XM-604M makes its home on a boat, in a trunk or side by side the amplifier will perform beyond expectations.


An Input for Any Application


A direct connection (High-level Input) can be made with the speaker output of your receiver if the unit is not equipped with RCA line outputs. High Level Sensing power on feature allows the unit to be activated without the need for remote turn on connections. For headunits that do have RCA preouts, the Sony XM-604M provides traditional RCA inputs for the easiest, most convenient connection.



Extraordinary Linearity and Control

Perfect Signal Transfer


The Sony XM-604M features gold-plated Screws, Terminals and Connections. Gold is preferred because it does not oxidize and is very conductive. Moreover, because gold does not oxidize, it keeps its conductive properties for longer than other materials and does Not corrode over time. Its this conductive property that makes such a connection perfect for seamless audio transfer.

Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

60 watts x 4 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

Amplifier Specifications

Marine Certified
Marine certified means that the unit has been designed and manufactured with a marine use in mind. It will withstand the harsh conditions that come from marine use. Generally, they are treated against UV rays and treated with special protective coatings.
Yes
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

AB
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
4
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

600 watts
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

280 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Any Gauge with use of Spade Terminal AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Rear ONLY @4ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
>0.005%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
No
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-Pass (LP)
High-Pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

80 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

80 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
97 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
No
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
25A x 2 
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Over 2 years old and still rocks the boat

February 6, 2011

Have had this amp in our boat on fresh water for just over 2 years. We are out every weekend and a couple days a week too. The amp is covered form most of the weather but had been through many storms and has got wet and has never failed. We use 1 deep cycle battery and can be cranking out the toons all day and in to the night with out having to start the eng.
Sounds great we love it.

good for basics

September 5, 2011

Well it would be good for a basic system in a fishing boat but it does not have enough power for the sony 10's but it does power the 6.5s great and the built in cross overs work well but not for the big speakers even brigded it still is bairly enough for the 10s to work ok. Would buy but its not as much power as it says! I bought 2 amps 2 10" subs and 8 6.5 all sony seem to be great just the amps. Power is over rated but works great for everything else!!

Does the job

September 11, 2015

Good amp. I'm not pushing anything too massive but it sounds good. It is bigger than I expected. I did not look at the dimensions before purchasing. I barely had room to put it where I wanted it in the boat. High and Low bypasses are a little annoying just because the are on specific channels rather than being able to choose. I think the low is on the front channel and the high on the rear. It did not seem to match with how I wanted to run the balance through the head unit so I turned them off, but it works as advertised. Not a flashy looking amp you will probably want to hide it somewhere. If you want flashy look or lights look elsewhere. All marine amps should be six channel, but this one does what it advertises.

Provides clean strong boost

September 11, 2015

After getting my boat with the factory head unit and speakers in it, I opted for sony's marine unit to add capability to the boat for using ipods-sirius-mp3 discs etc. That went great, as I could use many new modern devices, but the sound was terrible with my 2 little 25 watt RMS speakers. So then I dropped in some new polk (100 watt RMS) speakers. Much better sound but now the head unit couldn't push enough power to the speakers and the unit would start to clip the sound at higher volumes as it struggled to try and keep up. So to cure this I opted for this amp. Now I have what I consider great, clean, clear, crisp sound at very loud levels without any distortion. Now I am not the biggest audiophile out there and this is my first install of head units, speakers and amps but it is all very clear and easy to understand and do. I guess now my next move will to be to buy a sub woofer to run off the amp and then to buy a wakeboard tower and install some more speakers and then buy another amp to run those and then buy the remote commander for the stern etc...But seriously this amp so improved the overall sound and capabilities of my system that it is now something you want to use and listen to.

Great Price - Great Sound

September 11, 2015

We bought this for our boat to go along with a new Sony stereo, 4 speakers, and subwoofer. The sound quality with just the Sony stereo and speakers was not impressive, I was ready to return everything. Lots of noise and any bass sounded awful. We decided to give the stereo and speakers a chance by buying the Sony subwoofer and amp. I am so glad we did. After hooking everything up, which was easy, the sound quality was amazing. Everything from Hip-hop to high-treble 80's music sounds great. I was worried because Sony is not known for sound quality, but I am sold from now on. I hope this review helps. I could not find enough reviews when I was buying this product.

Delivers on its specs!

September 11, 2015

This amp was already installed when I got my boat 3 years ago...I've since configured this amp in 3 channel mode. Driving 4 Polk db651 coaxials (2-ohm stereo) and the bridged channel easily powers an inefficient 10" sub in a small sealed box under the helm of my 93' Searay bowrider. The output and sound quality is very very good and it never shuts down. Worth the money. In all honesty, I work for a competing audio company...and I have no reason to replace it with my employee discounted marine amp...

You get what you pay for.

June 13, 2016

I purchased this amp to replace my Rockford 400D when it unceremoniously broke after 2 years of use. As the title says you get what you pay for. I purchased this amp mainly due to its price point. Right out of the box i could see the swap was not going to be cut and dry. This amp has quite a large footprint. It also has very small terminals to land the power and ground wire which sucks as they suggest a 50a fuse and a wire rated to carry that load is much larger then the terminal it lands to. My Rockford had very nice lug style connections for the larger wire. The sound quality of the amp isn't horrible but there is noticeably less bass then there used to be out of my 6x9's. All in all it will serve its purpose. If I were running any kind of sub this would not be an amp I would purchase. It's adequate for standard house style speakers.

I paired the amp with a 4 Polk Audio db speakers and a 6 inch Bazooka sub with a Sony head unit. The entire set up cost less than $500.00. The sound is amazing! My stereo blows away those who have paid two and three times as much. I am very happy with the entire set up.
