I am looking to replace my stock speakers in a 2013 sonata GLS. I have read many posts on this forum concerning power handling and impedance. Are the front door speakers in the Sonata GLS full range or do they have a crossover and use the tweeters in the full full range sound? I am simply looking to replace the stock speakers most likely with something offered at Crutchfield.com. Crutchfield states that I need shallow speakers is this true. Will the stock radio be able to drive these for new speakers effectively? I have already added a sub box with two infinity subs and an ADS amp with in audio control LC2i. Also how do I add my cars modifications to each post like I have seen others done on this forum.
