Rated 4 out of 5★ by Musclebeach Fantastic amp for the price! Pros:*60W per channel x 4*This amp has one of the best Signal-to-Noise ratio's out there @ 93db. Better than similarly powered 4 channel amps like Alpine @ 87db, or five Rockford Fosgate amps which vary from 80, 85 or 90db. Only Kenwood is better @ 95db.* Very easy to installCons:* Unfortunately it's one of the largest amps out there for this amperage rating at 15" wide x 9" long x 2 3/16" deep. WHICH MAKES IT VERY DIFFICULT TO FIT UNDER BUCKET SEATS! All the competitor amps I mentioned above are no larger than 13" wide and some even less. For instance the Kenwood is 11" wide, the Alpine 10" wide, and the Rockford R400-4D is only 9" wide. #all other measurements being nearly identical#* The other drawback is that the Crossover frequency for the rear channels #speakers# and the front channels #speakers# is the same at 80HZ. NON-ADJUSTABLE LPF & HPF! My front door speakers are only 6" dia and then my dash speakers are only 3" dia. The LPF & HPF #crossover points# need to be adjustable -like MOST amps- so I can keep all the frequencies below 100HZ or 120HZ from getting to my smaller speakers and distorting the midrange. But I can't do that with this Sony amp.Because of these 2 very bad design flaws, I can only give it 3 1/2 - 4 stars out of a perfect 5 star rating.But if the big size is not an issue for you and you dont have any small speakers #where the crossover point could be an issue#, then it could very well be a perfect amp for you. 06/30/2012
Rated 5 out of 5★ by jsound Happy with this amp For less than 100$ you have an unbelievable quality of sound! Mounted with a proper capacitor and thick enough wires gives you an awesome power and quality, better and less power drainage than XM-GTX6040 600W model (31 amps/h against 45 amps/h) that I also have and with the same or better performance.4 6x9 Sony Xplode are connected to this amp in my van and my music sounds superb!I can recommend this product!! 09/17/2012
