Well they are only 6.5" but this Audiobahn speakers really have a lot of power to them. Regardless of the amount of power they have, if you have them hooked up the right way, the sound quality is just amazing. I believe they sound better then the polk audio db650. They have about the same specs as the polk audio but what got me was the dB number and this audiobahn speakers have a higher dB. Overall the price is in good range you can still get them cheaper but great speakers for the sound quality you are getting out of them very happy with them i would really recomend you buy this speaker you will not be dissapointed!
This is actually a really good speakers, the are gonna make shake the mirrors in your car but is very impresive the sound you get from them, combine this with a set of good 6x9 speakers and you will have decent audio on your car
I put these in the back doors of my Jeep Grand Cherokee. My front doors already had 6x9" kenwoods. After replacing my back speakers with these audiobahn's, I realized the difference in quality and had to replace my 6x9's. Overall, excellent quality for the price.
Be warned...the magnets on these beasts are huge. I had to clearance some metal inside my doors to make them fit, but not really a big deal. The end result was good bass, mids and highs. Mounting holes are a little covered by some black plastic, but it was ok after some fitting.
