My infinity PS-212 just stopped working 3 days after i bought it it just stopped working for days at a time then it randomly turns back on and works but repeats the problem and i never know when its gonna work the light on the back of the sub that is supposed to turn red if the subwoofer doesnt detect your amp is not working either its alway stuck on green even when i disconnect the subwoofer cable from my amp (it didnt do that when i first got it) i thought it was my subwoofer cable at first so i bought a 90$ dollar Monster THX Subwoofer Cable nothing i tried hooking my infinity to 2 different home theater receivers including my own still nothing my old 8 inch Accurian 100 Watt powered sub works like a champ on my amp so i know its not my receiver and i know its not any of my cables either i never turned the sub up anywhere near loud enough to blow it but i started to notice a faint burning smell coming from the back of the sub and i havent messed with any of the subwoofer setting on my amp since i got it so everything is the way it was when it worked and when it quit on me so im out of ideas on what it could be im really upset with this product and i wish i never bought it =/ and if your reading these reviews in order to decide if you want to buy any of their subwoofers DONT make the same mistake i did
