Fills a small car with large sound.
Good large sound in a small car. After prepping door with dynamat, bass is excellent. Lots of mounting hardware. Only minus I can think of was the foam mounting/sealing tape was not thick enough to seal the recessed groove around the speaker. I use the perforated sizing template from the box AND the sealing tape to mount the speaker. This worked just fine. Satellite tweeter has a flex mount system that works very well. Looks factory.

Best bang for your buck!
These speakers sound amazing for what they cost. For under $100 you can not go to any audio shop and get quality component speakers for the price you pay. The bass hits hard for it's size and clarity is crisp. Infinity and Polk Audios line of speakers are both I would recommend getting which BestBuy carry both of. Depending on if you like bass more, go with an Infinity speaker and for clarity go with Polk Audio, but both are great!

Nice component set
I bought this set to replace the rear speakers in my truck. Wanted to upgrade to a component set but didn't want to spend a lot of cash. These infinitys fit the bill. I know there are less exspinsive sets out there but these looked nice and had good reviews. I installed and connected them to an amp. They sound great and gave the music more depth. Going to upgrade the front with a 3-way component set soon. Should sound like an opera house in there.
