Alpine Spr-50c 5.25-Inch 2 Way Pair of Component Car Speaker System

My vehicle is a 2005 Pathfinder with the upgraded Bose system. 10 Speakers with Bose "components" in the front and passenger door location and two 5 1/4" Bose subwoofers located in the cargo area. Tweets for the front area are located in the top of the dashboard.For phase 1 of my upgrade I replaced the front system speakers only. All I can say is wow. The Bose system does not sound that bad by itself and when compared to other factory systems out there it sounds upgraded. However, when you compare the Alpine speakers to the Bose speakers still installed in the rear passenger compartment the difference is very surprising. Using the fader control to switch between the Bose speakers in the Back and the Alpines in the front it becomes very obvious how cheap Bose really is.The sound is nice and crisp with all the tones jumping out at you. Love the detail of the tweeters with the cross over set at zero. I have read some reviews that indicate the tweets are too high but I really think it depends on what you listen to and what your tastes are. The Alpine reference speakers are designed to present the music as it was recorded. They do not arbitrarily change the sound attributes of the music.Phase 2 completedUpdate; I've now replaced the rear passenger door speakers with SPR 50 C's. I'm hearing sounds in my music I did not know existed. I will say that these speakers will bring out the good and the bad in your music. If you listen to music that is not produced very well, then you will notice it more. If you listen to music that is very well produced then wow, the music will jump out at you and will hear everything as it was intended. Poorly produced music is hard to listen to now, I have to admit. I'm more choosy about what I play now.I wanted to update this review as I have finally finished installing all of my Alpine components. I want with the INE W960 Nav HU, PDX-V9 five channel amplifier, and subwoofer in the back. The full upgrade was done one component at a time and with each addition the sound quality improved. I cannot say enough good things about Alpine. As long as the system continues to perform I'll always turn to Alpine for my equipment needs.

I love this speaker so small but sound good including tweeter but for some reason the cross over keep on melting when I had a matching amp same brand.

These Alpine Comps are definitely worth buying through Amazon they aren't much cheaper anywhere else if you get free shipping. THEY ARE AT BEST BUY FOR 300 A PAIR.... These speakers sound wonderful I went the fun route and ran new Z-series wiring for a crystal clear sound. Its really not that difficult to mount the tweeters either my doors are so thick that i didn't even have to use the mounting ring on the back they are stuck in there on their own. YOU BETTER PLAN ON USING THESE WITH AN AMP. I only used a 300 watt alpine 4 channel however i ended up with one rated at 92 watt per channel from Best Buy (should have been 75 watts per b/c 300 watts/4channels) according to the birth sheet with the amp. I would say if you have a good-excellent Headunit with solid output (mine is a Alpine Double IVE) then you should be fine with about a 300watt 50watt per channel amp. If you are however trying to run these on a stock Headunit or cheap 100 dollar thing from Best Buy you may need some more juice. Highly recommended to anyone that will take the time to make it sound good but you should probably get a sub and another amp or get a 5 channel.

These speakers were purchased to be replacement speakers for the Door speakers in my 1996 BMW 328I. As it turns out the Tweeters in the box are the correct size but the mids are not. I ended up using the mids to replace the speakers in the back window so it all worked out AND they do sound great.

received them, don't work called alpine and they said ive never seen a case where a customer has received a bad set of our speakers because we test each set before they leave the shop but it sounds like you received bad speakers

I tried this set of Alpines in my E39's original non-DSP headunit. After years in the heat, the original speakers lost their original frequency response. The Alpine is a 5 ohm speaker, which matches the impedance of the original Nokia door speakers. The E39 has three speakers in the front door: a tweeter by the A column, a midrange by the handle, and a bass mounted in a plastic echo box near the floor. However, the large Alpine speaker is really a mid-range and bass combo. It fits the echo box if you get longer screws.The mid-range component causes the speaker to buzz in the echo box. Attempting to mitigate the buzzing, I tried padding and then butyl tape to no avail. I also disconnected the midrange and hooked up the twitter just to try it out. The sound was not as good as the original speakers. Additionally, the buzzing made the Alpines too distracting to use. If they had sounded better, I could have tried throwing away the echo box and mounting the speaker directly to the door card.I ended up buying new Nokia mid-range and bass speakers from the parts department of an online BMW dealer. There is one company (Bavsound) that sells direct replacement aftermarket speakers for the E39, but after this Alpine experiment, I decided to go the original equipment route. It was about the same price.The car does not run without the existing radio (MID Module). If you get an aftermarket headunit, you still need to keep the old MID hooked up somewhere like the glove compartment. In other words, there are not many options to do a simple aftermarket speaker upgrade for the car. Your choices include doing a simple speaker swap using BMW parts or speakers from one other supplier. Or, you go all out and replace/add a lot of components like the headunit/Android control unit, add Bluetooth, a new amplifier,... Then, depending on what you get, the steering wheel buttons might not work.
