Bests & Worsts Reviews from Amazon

Picked this out for my mother who finally agreed to update her tv and sound system. Did side by side comparisons of a number of sound bar setups at my local Best Buy. The only other system that sounded as good was a Polk for twice the price. The similarly priced Polk didn't even come close. Ordered it through Amazon for my mom and received delivery of the item. Setup was easy, though programming the remote did take a couple of tries for each button. Sounds great - I recommend the wall setting even when using on the table, bigger sound though I don't know what they do differently. One week later is where the problems start. My mom calls and says there is a frequent popping noise. I go over to check it out and find that every time the sound signal is interrupted to the wireless sub it pops - changing channels, some commercials, turning on or off, etc. Additionally when the soundbar is powered off with the remote the sub hums very loudly. The back of the sub was pistol hot - hmmmmm. Flipping the power switch off on the sub makes it eminate a loud squeal. ???. Tried all four wireless channels to see if it would help, it did not. Tried the RCA analog inputs instead of the optical and it did prevent the popping while changing channels - all other problems remain. Looking around on the internet shows I am not the only one with this problem. Currently have an email in with customer service at Boston Acoustics to see what they say. Will update here if I get help. Cannot recommend this right now due to obviously QC issues. Too bad - because when it works it sounds great.
