Summary: These fit perfectly in the rear of a 1994 Buick Roadmaster wagon, and sound better than the originals. If you replace the rear speakers in a 90's Roadmaster/Caprice/Olds wagon, you have to make sure they aren't too deep, which a lot of new 6x9 speakers are.
Summary: Unit has less bass than I originally presumed. It's ok in loudness for stock 4x20-4x40W RMS radio's; does not easily get overdriven. Tweeters crackle with my 4x52W RMS digital Sony radio head, I guess they're just made for stock radio systems!
Summary: I really like speakers i have a 2001 alero and the headunit took forever to get in so i figured the back speakers would be the same difficulty which were 6x9's were actually easy to get out and replace.
Summary: I bought these as a gift for someone whose speakers were blown. I've always been partial to Pioneer for my electronics. Although the search engine within this description indicated it would fit her car, the speakers would only work in the rear. Her speakers happened to be blown in the front.
Summary: Speakers work great and sound great. I put them in my 97 Accord with no problems, although they were a little high when putting my stock grille back on (I got it to fit though). They were easy enough to install, and you should only need to look up the correct wiring on the internet, if you need to.
Summary: I overhauled my entire stereo system in my 2000 Civic recently. The Pioneer TS-A6973R speakers were a direct drop-in replacement for the factory rear deck speakers. I powered these 2 speakers with an audiobahn A2002V amplifier which seems to match perfectly. The speakers have great high's and low's.
