do not bridge in three

matthew from West Columbia, SC, Sonic Electronix
16 April 2012
  • Conclusion: I got this amp to put behind the back seat of a supercab, It's a great amp but i don't recomend bridging it. I tried that, and in about 15 minutes it got too hot to touch, so I'm getting a second amp for my sub.

Best bang for your buck

Dylan from Colorado, Sonic Electronix
28 November 2011
  • Conclusion: I have a '97 TJ and space is seriously lacking. Add to that no security and the high risk of the elements. I needed something just to be able to hear my music and this little amp does the trick. It is insanely small. I was able to tuck this bad boy upside under the drivers side steering column and because it is fan cooled it has no problem staying cool. It is completely out of the elements and is impossible to see without shoving your head up into the dash.

Nice little unit

Adz from Adelaide, SA, Australia, Sonic Electronix
16 October 2011
  • Conclusion: Purchased this around 6 months ago and I am quite impressed. Sits nicely under the passenger seat of the jzx100 or Toyota Chaser. Provides good power to 6.5" door speakers. Not the loudest as it's not hugely powerful but certainly good bang for buck.

Awesome power

Wayne from Corpus Christi, TX, Sonic Electronix

  • Conclusion: These amps are small in size but huge on sound! An excellent deal. I have a pair of these and a pair of the mono amplifiers and they scream! Looking forward to getting more for my next car!

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).

Great Amp

Steve from Vancouver, BC, Canada, Sonic Electronix
5 December 2010
  • Conclusion: I bought this amp specifically because it was the only amp I could find that would fit under my seat in a Ford Ranger pickup without any issue. I was very impressed with the power from this small amp. I'm driving front component speakers and one 10" low profile sub. My system sounds absolutely awesome. This is a small but powerful amp.

Love this AMP!!

oosh325, Ebay
23 November 2010
  • 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!

I wish I bought two

Joshg from Madison, Wi, Sonic Electronix
15 September 2010
  • Conclusion: I bought this to upgrade an Infinity amp and speaker system for a 2002 Jeep Grand Cherokee. The amp was the best I could find that would fit in the tight spot under the seat and did not cost hundreds more. It is a good clean amp and runs 4 Rockford Fosgate speakers very well. It hasn't overheated yet and the high level inputs made the whole upgrade possible without replacing the head unit. Very good value.

Great little car amplifier.

chleong1, Ebay
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.
