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. They are a bit large but other than that with the grills or not they are beautiful and great sounding speakers. The price is hard to pass up for what you get.
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.
Conclusion: Great speaker. Price is on par for the quality and brand name. Sonic always has the lowest prices! Good, loud speakers. Clear highs, although not the "crispiest" (That's what tweeters are for). Really loud Hi-Hat cymbal hits or loud crash cymbals can be a tiny bit distorted, but not really noticeable when rocking out! Nice high-mid range to around 100-80Hz bass. I play all kinds of rock, country and some rap. So A good testing mix. Worth it? Heck yea!
