Summary: Swapped out the stock speakers in my 2014 Jeep wrangler Sport. The stock speakers were 6 1/2 " but Crutchfield recommended the 5 1/4" speakers with the adapter kit. I wanted a quick swap out without a lot of fuss and thats what I got.
Pros: a good quality speaker, good directions, easy upgrade for the do-it-yourselfer
Summary: I purchased these speakers for my car from a local store called Sound Systems LTD. The only difference is that I bought the 6 1/2 inch speakers. I originally planned to buy the component system because I blew my factory tweeters and currently have none.
Summary: Very clear and detailed sound, even running of factory HU; looking forward to how they will sound once amplified. Included everything I needed for install with very quick shipping. High quality experience all the way around.
Pros: Ease of installation - Sound Quality
Cons: Cost somewhat high compared to other speakers within size range, but worth it.
Summary: Disappointing low frequencies and only moderately better midrange than stock speakers. Not very efficient. The supplied installation adapters required modifications to work on the back deck although fit perfectly in the doors.
Conclusion: These were a bit of a splurge but I think it was worthwhile to buy them. These speakers are a good answer for someone who wants to get quality lows, mids, and highs from a coaxial speaker pair. I did not want to get into high end component speakers and I am very satisfied with these.
