Question: As in other reviews the rear speakers would not connect. The seller is unwilling to replace the rear speakers. After communicating with the seller, they called me a liar and refused to give support. Called Amazon and was given a handful of lies and told that amazon is not responsible for the people they allow to sell products. So end of story I do not recommend using the seller or amazon for any purchase.

negative
