By bro-in-law has a durango and the speakers will occassionally go out (one or two at a time). Not sure if it has the infinity system in it. If so, I know they use a factory amplifier. Is this a one unit amplifier like I have in my grand cherokee or are there separate amps on the speakers like the ones I pulled out of my 2nd gen Ram? I'm trying to figure out what he'll need to replace.

 

One amp. It is behind the passenger side kick plate.

 

Thanks.

 

NP glad to help.
