Conclusion: These handle bass really well and a nice smooth high end that doesn't get lost in the mix. I am currently running them off the head unit and I am very happy with the performance. I only imagine I will like them more once I get the amp installed.
Conclusion: I bought these speakers to replace my factory speakers and I tell you what I wish I would have done it years ago they are great I have a factory player yet but the sound quality is intense good solid base and crisp clean highs I would definitely recommend especially for the great price
Conclusion: I put 2 of these in each of the doors in my Civic Coupe custom fiberglassed up. Got them about fully powered @ 150rms per door. No joke, not only do they play everything beautifully, they shake my windows and doors just from that amped up power. Full-range great quality, love every bit.
Summary: Great x9's. You really cant beat the price! Rockford for life! This is my first set of Rockford speakers and they blew me away! I run them at full tilt all the time without clipping and they handle it sooo well!
Conclusion: I purchased these speakers to replace the blown factory speakers in my 2004 Jeep Grand Cherokee. The installation took about 45 minutes and no modification was required. The Rockford Fosgate speakers have improved the sound over the stock speakers.
