lost

i have a sentrek amp that i have had since 1996. i have no paper work and havent had any luck finding any info on the net. its a four channel amp,mosfet,bridgeable and is model #spa840d. if anyone has heard of this amp and could give me any info on it, it would be greatly appreciated. i want to hook it up but dont know what it can do or if it is worth hooking up. thanks

Sentrek was a cheap brand from the 80's-90's, may be good for running some coaxes. You may have to find who the parent company was, they may still have some info.
