how do you convert a passive subwoofer to an active one ? Answered
i have a sony reciever, and it has an active (externally powered) subwoofer output. i recently acquired a set of sony speakers to replace the old ones i accidentaly blew. all speakers connect normaly, except the subwoofer, which uses two bare wires. i need a way to convert this subwoofer, which uses an outboard amplifier, to one with an onboard one. oh, and it has to be for less than $35 , because for that money, i could buy a new one, at goodwill. many thanks !
