if a company is being vague and hesitant to tell you anything more about said product, then I would steer clear from them. Sounds shady. Any reputable company or dealer would be willing to give you some kinda info when you asked.
Orion amp is pending.
Kicker amp and the hca-25 still available. Accepting offers now. Not really looking for trades except maybe for anime stuff, video game stuffs, attachments for my nikon d5000, etc etc.
on the back of the sub it should say if it's dual 4 dual 2 etc. each coil should see a reading of 2 or 4 (whatever your subs impedance is. if it reads lower or nothing, then it's fuxored or if it keeps jumping around.
