Improved the sound in my car

ken2001, Ebay
6 March 2011
  • Summary: I purchased a XRONS car stereo, and the sound was very poor. I have a 944 with 10 speakers, so perhaps it overwhelmed the XRONS (though my old Kenwood sounded much much better). I've never purchased a car amp before, so I was not sure what to expect. Sony products have disappointed me lately, but the XM-4S has restored some of my faith in Sony. It was easy to hook up, takes up little space, does not draw a lot of power and stays pretty cool (and looks very cool as well).

  • Summary: I love this amp! Great power output for an amp of this size. I purchased this amp to fit under the passenger seat of my IS300 and it fit great! Beats the pants off of the factory system. I would definitely recommend this amp to anyone looking to upgrade their factory system!

Great little car amplifier.

10 May 2010
  • Summary: I have a small car with very little space for car audio equipment. I found the Sony XM-4S unit to be the perfect amplifier for the car. Its small, compact, and does a great job amplifying the signals from the car's standard head unit. Note, I just wanted crisp clear sound in the car so I used two sets of good coaxial speakers in the car without a sub-woofer. The amplifier has been working great so far.

Great ebayer

  • Summary: I bought the Sony XM-4S it was as it was listed in the auction. Features 500 Watts 50 Watts x 4 at 4 ohms = 200 Watts, 60 Watts x 4 at 2 ohms = 240 Watts. Or 50 Watts x 2 at 4 ohms + 120 Watts x 1 = 220 Watts, or 60 x 2 at 60 Watts + 120 Watts x 1 = 240 Watts.

better than expected

  • Summary: The main reason I bought it was it's big power compared to its small size. I've had good luck with Sony sound products. I was ready to pay retail when I found it on ebay.

Sony XM-4S amp

7 June 2008
  • Summary: It's the only compact, reasonably powered amp on the market. I replaced an early '90s Sony amp of similar style. It was a great price too.
