What customers say about "Key Specs"
Alpine SPR-68 2 Way Pair of Car Speakers
  • I replaced my Pioneers with these, added an amp and new reciever and wondered why I did not do it years ago. Awesome sound.
  • All 4 played loud and clear type R is all I buy needs amp 75 watts rms or bigger in my f-250 but that fords fault the back seat hides the speakers after 3 months one went bad and made my alpine amp go into protection mode for clipping replaced with a Rockford fosgate
  • Great speakers definitely recommend them! I put a small alpine amp to them along with my alpine hd head unit everything sounds absolutely amazing im very happy with this product
  • Great, great speakers! Have had the speakers for a while, but finally got them installed in May. I must say, I am very impressed with the quality!
Infinity KAPPA 682.11cf 2-Way Car Audio
  • Love Infinity's attention to detail with included small plastic adhesive logos for the door panel speaker grills for a premium factory looking setup :)
  • Well worth the money. Great quality speakers and customizable down to a "T". You will not be disappointed.
  • Great product clear sound from the highs through the lows. Much improved compared to the set I owned 10+ years ago! Thanks!
  • Installed (4 ea.) these in my f150 and powered them with the Sony MEX- GS820bt. With no sub and "plug and play", I must say, system sounds MUCH better than stock. Looking forward to "fine tuning" the sound even more after familiarizing Myself with the many options.
  • I gotta say these speakers are amazing!! I just installed them in my 2010 F-150 and they are soooooo clear.

What customers say about "Audio"
Alpine SPR-68 2 Way Pair of Car Speakers
  • Good clarity, some distortion at higher volumes. I noticed many reviews that highlighted no distortuion. I'm only running 100 watts per speaker, otherwise wish they were a little cheaper, but good value and sound for the price.
  • Replaced the factory 25W RMS speakers with these 100W RMS speakers and now my music is both clear and blaring! Had to purchase a new amp though... POWER!!!!
  • Great sound quality, exceptional price for a full replacement of my stock speakers sound is amazing and undistorted even at full volume w/o amp, can't wait to see how much improvement an amp will make!!!!
  • I don't have sub woofer in the back yet, but I don't need it right now because the way the speakers sound! Awesome and I am very happy!
  • Crystal clear sound, can crank it up as loud as I can handle and no distortion whatsoever. Great speakers!
Infinity KAPPA 682.11cf 2-Way Car Audio
  • These speakers sound crisp and have a great clarity. I would recommend these.
  • Sound is fine but they did not come with covers.
  • Very clean and clear. Supports enough bass for all kinds of music but with a very clear sound.
  • Very happy with both but I would say these are probably slightly better than the Polks. Cleaner, clearer sound. Would recommend.
  • Impressive range and clarity/separation for a speaker in this price range.

What customers say about "Features"
Alpine SPR-68 2 Way Pair of Car Speakers
  • Clear sound and easy to install. My system has never sounded so crisp.
  • Great Speakers. Simple installation, as long as you buy all necessary parts for connection.
  • I have not installed all of them yet but I have installed two of them and so far all is well as I ordered .
  • A markable difference in upgraded speakers paired with a pioneer deck the speakers are much better than the stock ones that came out of my vehicle
  • Speakers are great but one of them arrived broken. Tweeter was cracked off from speaker.
Infinity KAPPA 682.11cf 2-Way Car Audio
  • Easy install with included factory harness adapters.
  • The included adapters for my Navigator did fit great to the factory wiring, but were useless on the speakers.
  • They have with different mounting points and all you do is figure out which ones you will use for you vehicle and easily trim the ones you don't need.
  • Only con is I had to clip the mount ears to fit in the door. It was super easy with wire cutters.
  • Fit perfect and used the screws to install. Took ten min... buy them!!
