About the Rockford Fosgate T1650

Alexander H.

Power play

Rockford Fosgate builds their Power Series speakers for people who won't put up with inferior sound in their cars. These Power T1650 6-1/2" speakers utilize advanced design elements to ensure that they'll deliver superior sound in your vehicle for a long, long time. The lightweight polypropylene cone is reinforced with strong carbon fibers so it'll keep its shape when you're pushing the speaker hard. You'll hear accurate midrange and bass reproduction, while the 1" aluminum dome tweeter makes the high frequencies sparkle. These speakers will handle up to 75 watts RMS so you'll want to use an outboard amplifier to get the most out of them.

The tweeter is mounted on an offset suspension system, minimizing any acoustic reflections.

Signature Rockford Fosgate design

Proprietary VAST™ technology increases the woofer's cone area without increasing the size of the basket. This larger cone gives you deeper lows and more power handling, and it's supported by a durable rubber surround that's designed to last a long time. Rockford Fosgate mounts the tweeter on an offset suspension system, minimizing any acoustic reflections from back of the tweeter and maximizing accuracy. And open slots on the frame make it easier to install these speakers if the factory holes are slightly off, especially in certain European imports.

Product Research

Features

Injection-Molded Woofers: The woofer cones are injection-molded carbon fiber filled 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.

Tweeters: Each speaker features a 1" treated aluminum dome tweeter mounted to an offset cantilever to eliminate frequency response anomalies due to acoustic reflection between the woofer cone and the rear of tweeter. The tweeters are angled so you can direct them toward the listening positions.

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.

We have not been able to research one of or acquire parts made specifically for the 2021 XP1000s. We don't know if these speakers can work. This may change in the future and I recommend contacting an advisor by calling 1-800-324-9695 to check our current inventory

If the Crutchfield site itself says that they don't fit it may be an error on their part. I bought these to put in my 2000 Suzuki Vitara and Crutchfield said they didn't fit, but many different websites said that 6.5 was the correct speaker size. So I bought them anyways and they fit perfectly.

Idk. I installed them on a 2013 Harley Davidson Streetglide.
