1. the sound. that's what it's really all about. although AAM has options on single and dual plus a few oher option they do not have the customizable options of the system the FI has. also I've heard every version of the FI system and every version of the AAM system and PERSONALLY I like the FI sound better.


2. is the customer service. I PERSONALLY have never had an issue with AAM but I have seen some on here say they did

FI really does have the best customer service I've dealt with in any aspect of buying a product car or non-car related.
