A:AnswerAs long as your karaoke system has standard speaker output connections (bare wire) and are compatible with the specs for this speaker (10-150 W per channel, 4-8 ohms), it will work perfectly.
A:AnswerBose 301 speakers have the bare wire spring clip connector on the back so you would need a length of speaker wire (size requirement determined by length needed, I typically use 16), but no cutting off of ends is needed.
A:AnswerBose speakers work best at 6 ohm impedance outputs from receiver. Purchasing a new receiver now usually has speaker impedance from 6 - 16,000 ohms and is worth the added cost to make these speakers pop.
