I usually do not leave product review but because I feel burn so badly on this one I have to say something to warn everyone else . I be actually online search for a way to remedy the pop and hiss , think I must have be do something wrong , and then I run across other review that be state the same problem that I be have . this system really be pathetic peace of junk and I have be totally embarrass by they on more than one occasion . they will pop and hiss -lrb- loudly -rrb- then the sound will totally disappear . forget this system and do not give Panasonic another dime . if I be look for a new system I would go with bose . yes , bose system be expensive but they know have payment option on they website and I can guarantee you will not get these type of review form they system .
