Dxi 651 speakers

Polk has never disappointed me. The quality of product is much better vs Kenw00d or P10neer. So is their quality control and testing. I like how it came with a foam type of spacer to go between the speaker and door panel- helps reduce vibration kind of like Dynamat would. Some of their speakers I had before had like a spray-on rubber? on back of the speaker frame. Clearer sound always with them.

Very good sound

Purchased these speakers to replace a set of worn our speakers in my 99 Tahoe. These were of considerably better quality than the originals and installed nicely in place of the originals. These speakers have a significantly improved base response over the stock speakers. and do not distort when driven by the stock amp in the Tahoe. This was a good solution for a replacement speaker that made a good sound system even better.

Polk good OEM Replacement

Nice sound for OEM Replacement speakers. You may need brackets for Subaru Crosstrek or use cheap OEM speaker housing and cut out old woofer to make adapter for this speaker.

Good sound at a good price

I installed these in the front of my 2004 Honda Civic LX sedan. They fit with no issue, using a 0.5" thick mounting bracket (the speakers come with their own, but I reused the bracket from the previous speakers I had installed).

The sound is good, especially for the cost. They do not provide deep, powerful bass, but would be a great improvement over most OEM speakers. I use these speakers alongside a subwoofer, so I want the subwoofer to handle the low frequency end anyway.

Miata spesker replacement

I got these speakers to replace the stock speakers in My 90 Miata. They were a direct replacement other than having to drill two new mounting holes. The speakers fit fine with room to spar and the stock grills covered them fine. The speakers are a great improvement over the stock speakers.
