I just finished installing a set of Alpine SPS-610C speakers in a 1995 Mustang convertible as replacements to the stock 5x7/6x8 “premium sound” Ford speakers. They are driven by a 16 watt per channel Alpine iDA-x303 head unit without an external amplifier.

The SPS-610C woofers were mounted in the stock door locations using ¼” hardboard to adapt the stock oval hole to 5” round size needed. Making an adaptor was fairly simple – cut a 5” circle in ¼” hardboard, use an old speaker to trace the speaker shape centered on the circle hole you just made, make the final cut about ½” bigger than the speaker line and your template is done. Now make a second one for the other side. You can choose buy adaptor plates with the 5” hole precut.

I mounted the SPS-610C tweeters high on the door panel through a trim plate that covers the side mirror mount by cutting a 2” round hole in the plastic. Alpine includes parts to mount the tweeters in a variety of ways including surface mount so you can put these little tweeters just about anywhere you want.

Since I do not do this kind of work on a regular basis, installation took several hours because of the custom cutting required. SPS-610C speakers are connected to the head unit by running the stock speaker wire first to the woofer then connecting a second supplied wire, with built in crossover, from the woofer terminals to the tweeter. Alpine provides wiring and crossovers for the tweeter, but be aware that Alpine DOES NOT INCLUDE PIGTAILS to connect the woofer to your stock speaker wires. You will have to solder your own pigtails, which I chose to do, or buy one of the various stock speaker connector wires specific to your vehicle. I had to take one start off the Value category for Alpine being chincy.

The stock rear speakers were also replaced with Alpine SPS-517 Coaxial 2-Way speakers. Alpine DOES include the pigtails to connect the SPS-517 speakers to the stock wiring.

The sound created by these component speakers is a tremendous upgrade over stock even with the internal 16 watt per channel head unit. The SPS-610C component speakers provide a richer sound experience with better separation than a standard 2-way speaker. The woofers provide impressive low frequency sufficient to vibrate side view mirrors of the car at mild volume although nothing like the feel you would get from a dedicated subwoofer and amp combination.

The performance of these speakers is excellent for the cost. Paired up with the SPS-517’s in the back there is ample sound to enjoy music on the highway with the top down. For a bit more oomph, an Alpine KTP-445 head unit amp would provide a clean 45 watts per channel. However, if you are considering a high power external amplifier for your car you should probably spring for a Type-R or Type-X speaker set instead of the Type-S.

These speakers are the same as the Type S 6-1/2" coax speakers, but they come with a better crossover. (12db vs. 6db.) I have them powered from an amp at 75 watts each. The sound is good for the price. These could be powered from a good head unit with no problem. I installed them in a friends truck who didn't want to spend a lot on speakers (along with a 8" Image Dynamics sub), and he was very happy with this sound. And for just over $400 for these component speakers, 8" sub, amplifier, and Stinger HPM wiring, we now have an great sounding budget system and the interior still looks stock.

These Alpine Type S speakers kick! Great sound if you feed them the power they deserve. Crystal clear clarity. Only minor drawback is that the tweeters are a little too prominent. For component speakers these are well worth the money.

I installed these speakers into my '99 Blazer with the woofers in the door and the tweeters in the dash. It took several hours to cut the tweeter mounts and redrill the woofer mounting brackets on the door and to wire in the in-line crossover. That being said the sound clarity versus stock is night and day across all variations of music from alternative to dubstep these speakers perform. I am very impressed as to how low these speakers will go. In some cases its enough to vibrate the rearview mirror. The sound is extremely full and rich with clear highs. And I am just running them off of my Kenwood KDC-352U deck for now. Matched with a subwoofer this will be nothing short of an outstanding stereo setup. I recomend this kit to anyone looking for a great set under $100. Once again Alpine has lived up to my expectations.

These things are nice. Real simple and straight forward. For the 6 months i have had them they have been great! Take the rms watts really good. The highs and mids are real clear. Not muddy. I would reccomend this product to anyone

This component set plays very nice. Clear and loud the crossover does a nice job of separating the signals. The set also comes with a wide variety of mounting options.

I installed the sps610-c speakers in the front doors of my 2003 chevy avalanche and the 1" swivel tweeters in the windshield columns. it was a very easy installation upgrade to do. and the sound is FANTASTIC.

I bought 2 pair of these and have them with a 4 channel Alpine, sound is amazing for the price.

These sound awsome with a MRP-F300 hooked up to them. For this price, it is hard to find better sound! Loud and Clear! Can't lose

Set them up with a set of kicker ds35 on a crunch 1200 x 4 in front and ds 6.5 and ds 6x9 in back and you will be loud and proud.

cheap, great sounding component speakers for a great price... recomend 100%

I have these speakers in my front doors and they sound really crisp and clear. They are being powered off my CDE-124SXM and they still sound great. If you want to get more out of your speakers I would probably get the Alpine KTP-445, which I will soon be getting to get more out of my speakers.

For now i am running it on an Alpine head unit rms per channel is 18 these speakers handle up to 80 rms and with that small amount of power it is enough to hear clear sound with excellent midbass and with the volume you desire with no distortion.

These are great speakers and sound excellent. Very easy to install and sound great. I would recommend putting them on an amp if you want to add some bass!

I put these in a 2007 Dodge Nitro and the results were better than I had expected even with the factory head unit installed. Installation was a breeze with the included brackets and there were numerous mounting options for the tweeters included.

These speakers sound great and they were a good price!

Excellent price, even after shipping. Speakers sound great and huge upgrade from the stock paper cone junk. Even off stock head unit, very noticeable improvement in mids and bass. Highly recommended, especially at this price point.

I researched speakers for about 3 months for my avalanche and finally decided on these. I went to Best Buy and several other local audio stores and listened to these as well as others over and over again. I listen to a wide range of music from electronic dance to jazz and these really pick up the overall sound in song. I am very satisfied and purchased the matching SPS 610 for the rear. I was able to buy both sets at an amazing price.

This is a pretty good set of speakers if you are looking to upgrade affordably highs are crisp and they have good bass at certain frequencies.

These speakers are great! Would recommend to anyone look for a great sounding speakers to upgrade to, they are loud and the sound clarity is great.

These are great 6.5" Mids & highs by Alpine. The Alpine 1" soft dome tweeters are crisp & clear. These sound great and a great value. I would recommend these to anyone looking for some good Mids and Highs.

Good clear sound!

These speakers sound great.
