Summary: great buy would recommend to everyone.I had one needed another.this products is all LIKES no Dislikes. Besides Audison, JL is my second choice cause of price and reliability. I hope this review will help everyone out in choosing.
Conclusion: This amp is ideal for intalations whereby space is an issue or can not be compromised. With this amp I replaced an old alpine Amp that was also in the class of small powerful amps. I made a switch and noticed and inmense difference. It was so intense, that I had to dynamat the car panels. I was powering a JL w3 12" on a sealed enclosure and the sound was incredible. The bass was clean and deep- for its size unparalleled. This lasted about 8 months.
Conclusion: Very good unit in my opinion. I'm not a SPL guy, so I'm not sure what "cold" means. I previously owned a RF Power T500-1bd. It was a good sounding unit, but this amp sounds just as good in my opinion. Plus, JL Audio includes detents on all their adjustments, which surpasses any RF amp I've ever used as far as tunablity goes. Long story short, both amps are good, but if I where to recommend one over the other, I'd take this one. They cost about the same.
Conclusion: I definitely would recommend the xd600/1! It may be a little pricey but it powers my two 10 inch subs with ease. Its small footprint also helps to make installation in any location a breeze.
