I have a 2010 Nissan maxima s model nd my deck speakers aren't working I checked continuity of the wires to nd from the amp and the wire are good I check continuity thru the speakers they also were good I don't know what else to.do nd where else to check please someone.give me some.pointers and how do you know of you have the Bose audio system how can I tell cause it doesn't say it on the speakers

 

It'll typically say on the radio itself whether or not it's Bose. Take a digital multimeter and test for AC voltage from the amp if you have Bose, or from the headunit if you have a standard system. On an S package I doubt you have Bose.
