I have a 2009 386 Peterbilt, 4 8 inch Treo Subs, Dynaudio Mids and High, Zapco 1000.4 DC, and recently replaced my Zapco 1100.1DC with the Nano 4000. I purchased this from Boomers Audio in Tulsa Oklahoma. I'm usally the ginny pig for new line at the store. MY REPORT, 18-20 FULL TILT BOOGIE and the nano was just warm. It hurt me, BY FAR the strongest amp I have ever used on my subs. I dont know of any amp that can take that long of abuse. I quickly called and order a very large 4 channel. I have 5 batteries and a custom bulit truck alternator. I have 14.1 volts at the amps, the massive did not care. I have used some the best amps on the market and they fail within the first week. Many can play to store and back, but not many can play across the united states. Now I have to find 4 8's that can take the brutality that is the N4. Thanks massive, customer for life, as long as you dont sell out. Please feel free to contact me, I cannot say enough about how impressed with the line.
