Conclusion: Bought 2 sets of the Alpine SPE-6000 Speakers for my 2014 Harley FLHX , one set for the fairing and one set for the tour pak. These speakers sound amazing at 70mph and volume only turned up halfway! They are crystal clear, I highly recomend these speakers.
Conclusion: First I'd like to say Sonic is my favorite source for car audio and knowledge. However, according to them this speaker will not fit my 1998 Dodge Durango. I just put these into my Dodge this weekend without any modifications. Just thought they should know.
Conclusion: I used these to replace the factory garbage that came in my '09 Titan. They are getting 50W RMS of CEA 2006 compliant power from a RF amp and have handled it well for the past 6 months. These are in the rear doors and people who ride in the back seat tell me they sound great.
Conclusion: I bought these speakers because I bought a bucket. The speakers that were in it sounded bad. I love riding & listening to my music, so I decided to go with these because the price was right for my bucket & you really can't go wrong with alpine anything. These bad boys slap.
Summary: Purchased these speakers to install in a 69 buick electra paired up with a retrosound head unit. I only have two of the four speakers connected at this time, but the sound is great! More than enough clarity to hear and enjoy the music over the exhaust of the car.
Conclusion: These speakers are very good for the price. Just be careful with how much power you feed them or the bass will clip like crazy. Remember these are the entry level speakers but for the price and the cheapest Alpine sells. These rock!
Conclusion: I purchased two pairs of these to upgrade the door speakers in my new Nissan Juke. I couldn't be happier with them. They sound great and have no distortion even at max volume. I put a Bazooka Tube in the back for bass, and honestly my car sounds better than any stereo I've heard.
