I just got a set of these and like them a lot.
I had a set of J+M's in my 2009 GW and they were not worth the money IMHO.
Plus I had to send my front set of J+M's back to the factory because one just omit woking after 15 minutes of use.
I'll never buy J+M's again.
I wish the Show Chrome speakers were available back then I would have bought them instead.
