Slim Series 4-channel car amplifier
50 watts RMS x 4



Stock Status: Discontinued


Product Code: 158XM4S

Description Features Crutchfield Hands-on Research Accessories
 

Sony designed the Slim Series XM-4S amplifier for small vehicle installations, with a low profile that allows it to fit under most front seats. On the outside, the sleek inverted heat sink keeps vital internal components running cooler and lasting longer. Removable terminal covers keep all the wire connections protected and out of sight for a clean-looking installation.

Underneath the hood, the XM-4S amplifier delivers 50 watts RMS to four 4-ohm speakers — plenty of power for even the most demanding speaker system. Or you can bridge your XM-4S into 3-channel mode, sending 50 watts RMS of power to two speakers while driving a subwoofer with 120 watts RMS from the rear channel.

You can use the high-pass filter to tailor the signal going to your front speakers, or adjust rear-channel output with the low-pass filter and bass boost. Signal-sensing speaker-level inputs activate the amp automatically when it's connected to a factory radio, so there's no remote turn-on lead for you to install.

Pathetic Warranty Service September 30, 2009
Reviewer: Bob from Ann Arbor, MI  
Installed this Amp and the sound was great... for about a week.  Then it completely fried for no reason while playing classical music at soft volume.  Crutchfield referred me to Sony, and I've never had a worse warranty experience in my life. Nice amp if it works, but don't expect anything for warranty service.


 
Beautiful Music August 31, 2009
Reviewer: logan from Cincinnati, Ohio  
Very nice looking and powerful amplifier. Mounted in an '03 tiburon powering componants up front and 6x9s in the rear. Very clear sound and plenty of punch. Would buy this amp again.


 
Great little amp August 12, 2009
Reviewer: Paul from San Diego, CA  
This baby works very nice. I'm pushing a pair of Infinity 5020CS on the front and the rear channels are bridged to a JBL GTO804 in a sealed enclosure. The bass is tight and goes down w/o problem, mids and highs soung clear and good detail. I did use an oscilloscope to match the output of my Eclipse CD5030 to the input of this amp, and I can go almost all the way up in the volume w/o distortion. Very small footprint, I have it under the driver seat of Tacoma 01; it does get a little hot to the touch but the amp has a built-in fan. Nicely done Sony!

Reviewer: Alex M from Fairfax, VA  
This amazing amp fits perfectly in the factory location of my old Infinity amp. It
powers my two sets of Polk Audio db5251with incredible precision and
accuracy. I never thought that my Polks sound amazing until I purchased this
amp. If you have a car with limited space, you should definitely buy it.

Reviewer: Randall from NC  
A very clean amp that is small enough that it can fit in locations other amps won't. Driving Polk Audio 5.25" component set in the front and 6.5" component set in the rear. The music is awesome.

This is the third amp of this model that I've bought and I recommend it to friends.
