That's where your wrong. Orion is still Orion, same engineers same development. I have clamped this amp, I own 2 of them and my tested power at 14.6v was 4720rms at 1 ohm after box rise at 32hrtz. I replace my amps and subs every yr,and this yr I am toning it down as per a new edition to family. But 1 of these and a t3-tsns 12" or 1 more HCCA 124 will do plenty.
bad by the way, I have been running Orion and PG for 20+ yrs. no one really hears bout them cuz the price used to be outta reach for average competitors.
These amps and subs rock. Never a complaint.
