Actually, he could prove (somehow,I am no speaker expert) that the design was flawed. IE aa produced a product with a known flaw and marketed it as a good product. He has a few other similar options at his disposal.
Problem here is, best he could hope for is some small punitive damages. He may get a full refund but that is about it. Most small claims courts would dismiss this as petty. If it would have been alpine, rockford, etc, it may be a different story. What I would be worried aboutis libel. You have kinda accused AA of breaking a law without (what I feel from the posts) substantial evidence. Furthermore, why tell everyone, just do it and then maybe post the results. If I were AA, I would be 100x more afraid of a letter from a lawyer than a post on a forum. Lastly, all AA supposed rules are not enforcable in all states. For instance, in TN you have a guarenteed refund on all products within 7 days with a reciept. There is no such thing as all sales final.
If AA quoted one for a recone and then changed the price in mid-recone, it would be considered bait and switch. He could have said he woould do it for $20 and then charged $50. I would do a chargeback with my CC company and let AMEX hang thier *****, or just get my funds back after I recived the product to ensure they would not hold my product hostage.Send all e-mail transcripts to AMEX and they will handle it for me.
Again, I say you are stupid for posting " I am gonna sue" unless charges have been filed. AND it may be quite hard getting him to come to your state. Your e-mail and his marking plan qualifies him for "minimum contacts"...however....I think if your attorney sent him a letter, he would just send your stuff back and refuse to do business with you in the future.
