JL Audio C2-650 6.5-Inch 2-Way Component Speaker System
  • Replaced factory junk. Sound great for the price. Perfect 2003 Silverado fit.
  • The tweeter was a perfect fit in the Jeep's stock dash location. Very deep bass.
  • The size of the system fits perfectly into my car, now I constantly listen to music with good bass.
  • Replaced the old system, I am very satisfied, the sound is much better, the size of the system is well thought out.
  • Сompact size, good sound, deep bass and clear highs, I can not demand more.
Alpine Type R (R-W12D2) 12 Inch 2250 Watt Max 2 Ohm Round Car Audio Subwoofer
  • The box size for a 12 is relatively small but this thing will knock the ole socks off
  • I love that Alpine recommends the box size and type which eliminated the costly and timely need for trial and error.

What customers say about "Audio"
JL Audio C2-650 6.5-Inch 2-Way Component Speaker System
  • Highs are really clear and so are the mids with some bass. Really good system.
  • Not wake the neighbors bass but crisp clear, deep and LOUD. You won't go wrong with JL every time.
  • The speakers sound fairly neutral, have a good bit of punch and excellent detail.
  • Was decent for an factory replacement in a 2008 GMC sierra extend cab. Owner of truck was impressed.
  • Has considerably more bass than I was anticipating. Good thing. Also, pretty good mids and highs.
Alpine Type R (R-W12D2) 12 Inch 2250 Watt Max 2 Ohm Round Car Audio Subwoofer
  • Have had these for about a year and they still are great. Running them at 700RMS Each and it is incredibly loud. Would recommend these to everyone
  • This sub hits so low, I had an mtx thunder 4500 before this and this sub hands down is wayyyyyy better, I give it 700 watts rms and it shakes my whole car. For any price alpine cannot be beat in quality.
  • I have one of these running 700 watts rms and it blows everything out of the water. It hits notes my old Kicker CVR could only dream of hitting. The notes are so clear and smooth too
  • I have had two of these at seperate times...they both blew at 100 rms so i would reccomend only feeding then 800 rms or less. but they look very nice and i would buy again if they were on sale and i was looking for some more 12's
  • 750 Watts ... 15 Hour break in ... Clean Deep Bass. Ported 1.86 cubic feet
3-Position adjustable tweeter level, Mica-filled polypropylene cone

What customers say about "Features"
JL Audio C2-650 6.5-Inch 2-Way Component Speaker System
  • I purchased these speakers February of 2013 for my 2008 Impala and they are still going strong. Didn't need to cut, drill, or force anything to fit.
  • The tweeters look nice and have a jl logo on them, so at least people can know that you forked over some good money hehe.
  • Built perfect for a components type system they are designed for and I'm pretty sure once they get on an amp it will bring out a lot more of what they are capable of.
  • Easily best quality and ranged door speakers I've ever bought. Loud, clear sound with an excellent design.
  • The build quality is top notch. I do have an issue though. The protection circuit for the tweeters are too sensitive.
