Mine cost $650 with a 5year warinty at good guys! AND let me be the first to say that it is WORTH EVERY PENNY! that amp has tons of options! I meen whatever you wana do, you can do it with that amp! Remeber its not all about havin a 1000 watt system! My 500/1 will decimate alot of different 1000 watt systems, its all about how eficiant your amp(s) and sub(s) are! Keep in mind that the 500/1 has something like 800 watt peak... AND will make 500 watts RMS anywere between 1.5-4.0 OHMS, also will run the same from 11.0-14.5 Volts! All I can say about this amp is GOOD JOB JL!
