Good value

I used these to replace the front door speakers in a friends truck that he blew. They were fairly easy to install, and they sound great. I have purchased many other Rockford fosgate products and have been pleased every time. These specific door speakers are great if you don't want to put an amp on your door speakers, and just want speakers to run then off of your radio. Also a great price, worth even more in my opinion.

Mind blown!

These speakers are great for its price! Don't let the price fool you, good speakers can come at the lowest prices. I bought two of these for my '96 Jeep Grand Cherokee and these speakers KNOCK. They have crisp, clear sound and are very loud. You barely have to turn the volume up and these things will get loud. The bass is amazing as well! I put these in the front doors of my jeep and they hit like I have two 10" subs in the back! May I add that the two back speakers in my jeep don't work at all. You really can't go wrong with these speakers for the price. Rockford makes quality products and this shows it. I just installed these about a week ago so I still have to see how long they hold up, but as of right now I'm VERY impressed.

Great speakers at this price point

These speakers are built well, sound great, and are perfect for replacing factory speakers for better sound. Poly speaker cones to withstand the temps and possible moisture in a door cavity. Sound great in my Chevy truck.

Great Speakers and Great Value!

I replaced the factory speakers in my silverado with these and ran them off my aftermarket head unit and they are definitely an upgrade from stock. Once i got my equalizer set up the way i liked these speakers sounded great. Great value for the price.

Very great replacement speakers

I have installed these in two separate vehicles so far. Extremely efficient off of an aftermarket head unit. Not sure on how they would sound from a factory radio. Decent bass, good mids, and the heights are really good. Overall it it extremely worth the money u pay for the set of speakers.
