yep that’s exactly what we do! Or u can put both speakers in one muff and make it sound awesome! I love the harbor frieght muffs cause u can do whatever u want. And if u got crazy and wanted to hear your car you could take apart the lexin r6 and put it in your car. Which would be sick. Maybe I would do that sometime just Incase I needed to tune my engine when everyone’s on the track and I can’t hear!!
