can some one tell me whats one worth? cost?

 

The 4.6x? This one?: http://www.fortunecity.com/skyscraper/black/438/rf/4_6x.html



Not much, didn't make huge power. $50???

 

That was a great amp. About 40x4 real power. We used to bridge a pair of channels for sub and do a nice little system with them. It wouldn't rip your head off but it sounded good.

Value? $50-100 depending on condition.

 

The Series1 like the Orion Cobalt's don't tend to go for very much money which is not a true indicator of their quality. Both are fine amplifiers and quite rugged.
I would put the price range at no more than $100 for one in good condition.
