Was a little skeptical about how the sound quality would be at first but read numerous reviews online and consensus seemed to be that the sound was good. I ordered it online and shocked how quick it was delivered.(within 2 days) Sound and volume absolutely great. At first was having trouble indicating antennae till we realized I had the wrong base plate on for Sirius so switched it to other one in kit and problem solved. Especially like that you can run the entire machine from either batteries or plug in. Wish i would have bought one sooner.

Easy, works great in the house. No antenna issues at all. Sounds good.

No question this is about ten times as good as I thought it would be....It took about ten seconds to plug the radio in then BOOOOOOOOOOOOOM....WOW...hard to believe they could get that sound...HOME RUN ON THIS ONE (and half the in-store price)

I have not had ANY antenna issues, it worked right out of the box. I ended up taking my boombox to work and have the antenna pointing west and I always get 100% signal. I also LOVE the sound coming out of this!! At first, I thought it had a bit too much base but I was so used to my cheap Creative Bluetooth speaker. Now, I can't handle the poor quality of my bluetooth speaker. This is one of the best purchases I have ever made.

Have been using this particular boombox for some 6 months now with the very same in-car Stratus 6 SiriusXM radio, it runs pretty smoothly at home or on the beach, audio quality is excellent and love the design. The only thing is missing is the remote control, the US model (identical with the Canadian model, only the name is different) comes with its own remote control included in the box, unfortunately a remote control is not included for the Canadian model. It requires a SiriusXM monthly subscription, but with this boombox you're getting the home subscription for free, you simply take your in-car SiriusXM radio and use it at home on the boombox and vice-versa, no need for a SiriusXM home subscription anymore. I give it a 4 out of 5 stars only b/c of missing remote control for the Canadian model.

Doesn't work at all

Out of the box antenna connection does not work so box is useless. Looked online and MANY similar complaints.
