Wetsounds ?

Just got a new Wetsounds 10 sound bar and was wondering if wiring it direct to the battery was the correct way as long as it is fused close to the battery(5 inches or less)? I don’t want it to pull the battery down as it sits for extended periods at times just wasn’t sure if it drew any power when off, I read on here somewhere that this was the preferred way but was just making sure.
