I have an OS US made Orion Extreme 900.2. Its A/B military spec circuits will get that sub moving and make the best use of that subs SQ specs. Class A/B not as efficient as D class but some argue that A/B on subs has a noteably different SQ.. The JLs have enough VC temp rise that make it safe to power it with an A/B amp bridged. I used to run a PPI A600.2 bridged to a 12W7s with no problems, the sub section sounded killer.. Impacting bass with a ton of detail, never any problems with overheating.. The Orion will do well over 1000 watts rms bridged and will sound incredible with that JL, so will the PPI A600.2 which does in the mid 700s when bridged.. Both amps are OS US made and are famously underrated..
I have a few others as well, Including a PPI A600 which is all original never repaired, original warranty stickers intact, same with the Orion.. The Orion and PPI have about the same SQ, both sound amazing, the Orion has more power.. If this is an SQ system, either amp will do..
$275 for the Orion, $225 for the PPI.. Both include all plugs, the Orion is near mint BTW, the PPI is also near mint but the Orion looks slightly better...
