xenon amps are underrated. and if it's new, you have a warranty so if it ****s up, just send it back. orions are better and can take abuse better. can't go wrong either way.
ive been problem free with my xenon for over a year now... Another amp you may want to consider is the exile 800.4 heres a couple pics im thinking of getting one myself to match my 2400.1.
