Alpine R2-S65C

Features

Size Note: Alpine describes this woofer size as 6½, but because it requires a larger cutout than a standard 6½, Crutchfield has traditionally referred to this size as 6¾. Without adapter brackets the speakers fit many standard 6¾ applications. Using the included adapter brackets they can also be mounted in a variety of 6½, 6¾, 5x7, and 6x8 applications. Please enter your vehicle information to confirm fit.

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. Angled surface-mount housings are also included, or you can 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:

Crossovers: A low-pass crossover with a 6 dB/octave slope is attached to each woofer's input terminal. The included 12 dB/octave 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 31" input wires connect to the extra 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: 1½"
• Height: 1¼"
• Length: 2⅞" (3" including wire)

Tweeter Output Level: Each crossover has three tweeter output 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.
