Wife's Honda Crv

Nice speakers for the price.
I bought these to replace the stock, blown dash speakers in a 94 Chevy 1500. They are a little too tall for the speaker grilles to sit flat (the tweeter sits above the speaker about 1/8"), and they slightly interfere with the passenger side defroster vent tube, but that's universal fit for you. They sound good considering they're powered by a stock 20 year old am/fm radio though. I would definitely recommend them as an upgrade from stock speakers.

Great Speakers
I have a pair of these in my 2003 Cavalier, they bolted right into place, and they sound amazing! Running off headunit, these and my 6x9 NVX speakers in the back make a huge difference over the original speakers! Very impressed with NVX, and will continue to buy their products

Great Backfill
I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

Sound great
They really made a great replacement for the stock speakers that go in the dad of a 2000 chevy blazer, and they are cheap, which was a plus. They are also low watt so you can run them off just a head unit.
