Conclusion: i have this in all 4 doors of my lexus on my stock amp and my kenwood deck and it keeps up with my 15" sub i have on 780 rms. im wanting to mod my front doors and put the 5.25" version in and re-use my 4" i have now in a custom spot under my dash.
Summary: I put them on my motorcycle- BMW 1600GT as the stock ones leave a lot to be desired. Really added range and depth to the music, worth the price. While I had to do a little modification ( very simple ) they fit nicely and glad I bought them.
Summary: I have been a great fan of the Infinity Reference series speakers as I have now installed them in all three of our cars. However, the last two purchases I have made of Infinity Reference speakers, I noticed that the company is now owned by Harmon.
Pros: These speakers have great sound and are of top quality.
Cons: The mounting hardware, speaker wires and speaker grills were not included with the purchase. For what I paid for these speakers, these items should have been included. I would not recommend purchasing these speakers even though they sound great!
Summary: These are great speaker and easy to install we are putting them in a 1934 Ford coupe. while it will be a few months before we preform the final hook up of these we have never been sorry with any product that the Crutchfield team has recommended for our car.
Pros: Great speaker to fit inside a small early Ford coupe.
Cons: Didn't give it a full five stars we have yet to try them out.
Summary: Bought to replace pair of blown (not original) speakers. Installation was no problem. Sound is very good. Only gripe is that speakers lack a grill; will have to try to retrofit an old one or find a universal speaker grill.
Cons: No speaker grills, unlike others in the same line.
