About the Rockford Fosgate P165-SI
As solid as sound gets
Slots on the outer edge of the speaker basket make for an easier installation.
As solid as sound gets
Without a doubt, Rockford Fosgate's P165-SI component speaker system is a powerful alternative to the speakers that came in your car. Using an injection-molded mineral-filled polypropylene cone, the 6-1/2" woofer delivers impressively accurate sound. Rockford Fosgate's signature VAST surround technique also expands the surface area of the cone, giving you better bass response than comparable speakers. But no matter how heavy the bass gets, the separate 1" dome tweeter provides clear, extended highs for a rich full-range sound.
Rockford Fosgate makes installing this component system simpler by concealing each crossover in the speaker basket. That way, you won't have to find space behind your door panels for extra black boxes, but you'll still enjoy the clean sound that results when you channel your lows, mids, and highs to the optimum speakers.
Give your import some American muscle
Do you own a European car like a VW, Citroen, or Vauxhall? Rockford Fosgate designed these speakers with you in mind. Rather than only providing rigid screw holes that may not always match up to your factory speaker opening, the Flex 2 Fit basket design uses slots on the outer edge of the speaker basket for an easier match.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Injection-Molded Polypropylene Woofers: The woofer cones are mineral filled, injection-molded polypropylene. This molding process assures a uniform cone thickness for superior linearity and clarity. It is also light weight and rigid for decreased distortion and improved bass response.
Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.
FlexFit 2 Basket: The FlexFit 2 frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.
Size Classification Note: Some manufacturers, including Rockford Fosgate, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.
PEI Dome Tweeters: The 1" dome tweeters are made of Poly-Ether-Imide (PEI); PEI is a polymer film that produces a wide soundstage for superior imaging.
Mounting: The tweeters have multiple mounting configurations; choose flush or angled surface mount. The surface mount housing can be positioned at a 10° or 30° angle. Depending on the mount used, the installed dimensions are:
|Flush||Surface 10°||Surface 30°|
|Mounting Depth||0.912"||Screw Depth||Screw Depth|
Crossovers: The high-pass crossovers are integrated into the baskets of the woofers and the tweeters are wired to a second set of terminals on the woofer using the included wire. The crossover slope is 12dB per octave.
Speaker Terminals: These speakers have 0.25" wide positive (+) terminals and 0.187" wide negative (-) terminals, which are too large for the vehicle-specific speaker harnesses Crutchfield supplies for many vehicle applications. We recommend that a pack of assorted female quick slides (item number 120FQS10PK, sold separately) be purchased and spliced to the harnesses to adapt them to the speaker terminals.
