Can i connect 2 speaker boxes to one speaker wire ?

it's possible, , under circumstances, it's idea- have place speakers in series. there 2 reasons doing : when have amp puts out more power speaker can safely use- instance, amp rated output of 250 watts 8 ohms, , speaker 8 ohm unit rated max of 125 watts- or when impedance of speaker lower amplifier designed drive- example, amp rated down 6 ohms, , speakers have impedance of 4 ohms (which pull current through output transistors , blow amp). putting 2 speakers in series presents higher impedance amp, , halves power each speaker subjected to. putting speakers in series may sound difficult, it's ridiculously easy. speaker wire has 2 leads- positive , negative, connected red , black lugs on amplifier. split speaker cable , place positive side positive input of first speaker, , negative side negative lead of second speaker. place third, single wire of same gauge between negative lead of first speaker , positive lead of second speaker. in series. 1 practical use this: building home theater subwoofer cabinet containing 2 subwoofer drivers designed use in car audio. less expensive subwoofers built home use, have impedance low home audio equipment. putting 2 of them in series inside single ported cabinet can economical way generate lot of thump little money.
