About the Alpine R-S65C.2
Meet Alexander H.
I've installed car audio gear in a pumpkin. True or false?
I've driven all over -- up, down, and coast to coast -- and my best memories all have a soundtrack. Music is something I don't leave home without, and after enduring my fair share of crummy systems, I know that quality gear makes a long drive a joy. On those golden days, when the windows just have to go down, I need power and speakers that can handle it.
While I've clocked a lot of highway miles, I've also logged a lot of hours demoing car speakers from the best in the industry. And I've installed those speakers in a variety of vehicles, from sport coupes to minivans. Every listening environment is unique, every series of speakers has its own sonic stamp, and speakers perform differently depending how they're used. And while it's easy to get overwhelmed by specs, my best advice is to ask yourself. what's gonna put the biggest grin on your face when you just gotta turn it up?

Ready for high resolution
Ready for high resolution
With so many music fans relying on Alpine's R-Series lineup to enjoy their daily drive, these car speakers have achieved "classic" status. And now Alpine has leveled up their design to handle high-resolution audio. For years, home audio fans have enjoyed listening to speakers that extend way above the range of human hearing – now you can share that enhanced experience on the road.
These R-S65C.2 6-1/2" speakers feature a carbon fiber reinforced polymer (CFRP) woofer cone that satisfies a hankering for strong bass response. A deluxe surround allows extended cone movement for high-impact sound as well as resilience in the face of harsh conditions. And the extended frequency range of the separate R-Series CFRP tweeter lets you savor all the rich detail of your high-resolution music files. Alpine includes a pair of external crossovers that are compact enough to easily stash away in most nooks or crannies.
Handles up to 100 watts
Alpine has designed these speakers to work perfectly with your car stereo, but they'll really come into their own when you power them with an outboard amp. Power handling up to 100 watts RMS ensures you can get big, dynamic sound and plenty of volume out of these sturdy speakers. If you like to turn it up loud, Alpine R-Series speakers will give you a no-regrets sound upgrade.

Mids and highs are much more crisp than the stock speakers in my 2016 WRX. Set the tweeter to 0db as they come +3db from factory. Sounded to bright for my liking but might be ok for others.

Can the cross over mount on the inside of door where the back of the speaker is ?
I did mount it on the inside of the door between the speaker and the tweeter, there's a space you can secure it with a zip tie that's included.

Driver Materials: The R-Series speakers use Carbon Fiber Reinforced Polymer (CFRP) woofer cones. This high-strength, lightweight material is formed with its fibers aligned in the same direction as the curve and shape of the cone, thereby reducing resonant peaks. This balance of light weight and rigidity improves the speakers' mid-bass performance and dynamic range. CFRP is also used for the tweeter diaphragm, enabling the system to perform into the 40 kHz range.
HAMR Surround: The R-Series speakers incorporate Alpine's patented High-Amplitude Multi-Roll (HAMR) surround, a technology developed for Alpine subwoofers that maintains control and stability at higher volume levels. HAMR surrounds combine increased cone area and long linear cone excursion for deep, powerful bass response.
Tweeter Mounting Options: The tweeters come installed in a flush-mount housing. Once mounted, the tweeters pivot approximately 15° in any direction, to improve the stereo image. You can also install the tweeters behind factory grilles using the included stealth mount brackets. The stealth mount brackets can be top or bottom mounted; they have multiple tabs that can be removed when not needed. The installed tweeter dimensions are:
|Flush Mount (swivel)||Factory Location (bottom mount)||Factory Location (top mount)|
|Frame Diameter||2.291"||2.5" x 2.5"||2.56" x 2.56"|
Crossovers: A low-pass crossover is attached to each woofer's input terminal. Separate in-line high-pass crossovers are wired between the woofers and tweeters. Each woofer has two positive and two negative terminals, one for input from the amplifier, and one for output to the tweeter (via the in-line high-pass crossover). The 12" output wires attached to the crossovers are terminated with quick slides that connect to the terminals on the 30" wires attached to the tweeters. The quick slides on the attached 32" input wires connect the the terminals on the woofers. Because the crossovers are separate, the system can be bi-amped. Two-sided tape is included to mount the high-pass crossovers; their dimensions are:
- Width: 1¼"
- Height: 1"
- Length: 2½" (2¾" including wire)
Tweeter Output Level: Each crossover has three tweeter level options, allowing you to precisely tune the high frequencies to the car interior and tweeter placement. Using the supplied jumpers select -3 dB, 0 dB (flat), or +3 dB.
