Rockford Fosgate Power T165

Intense performance

Rockford builds their Power line of speakers for the true car audio enthusiast. The Power T165 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 70 watts RMS so connect an external amplifier to get the most out of them.

Rockford Fosgate innovations

Rockford uses their proprietary VAST™ technique to increase the cone area of the T165 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. The slots around the frame make it easier to install these speakers if the factory holes are slightly off, and they even come with plates that allow them to fit into oval speaker openings.

Product Highlights:

  • 2-way 6-1/2" speakers (pair)
  • carbon fiber and polypropylene woofer
  • butyl rubber surround
  • 1" aluminum dome tweeter
  • includes adapter brackets for 5"x7", 6"x8", or 6"x9" openings (brackets require modification)
  • grilles included
  • Vertical Attach Surround Technique (VAST™) increases cone area
  • power range: 10-70 watts RMS (140 watts peak power)
  • frequency response: 65-22,000 Hz
  • sensitivity: 88 dB
  • top-mount depth: 2"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Speakers sound outstanding!! The quality and richness of the speakers were more than I expected. Easy setup with all the extras Crutchfield added to my order!! I will order more products again!

Pros: Easy setup, instructions were clear

Cons: No cons!

Rockford puts out top quality car audio components. These speakers are ranked higher than the P165 and for its price you can't go wrong. Worth the investment! I've had the P series 165 and these are much better, I'm actually very surprised this got a 4 out of 5 on another review (no offense to my Atlanta boys). If you have a couple extra dollars to get the T series over the P I say do it. You won't be disappointed.

Pros: Great mid range for its size and impressive highs with the right amount of power.

Cons: Need amplifier to power. Factory system won't do!

Product Research


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

Butyl Rubber Surrounds: The butyl rubber surrounds dampen unwanted harmonic distortion while maintaining linear geometry under extreme weather conditions. This leads to less distortion, superior frequency response, and superior durability.

VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.

Tweeters: Each speaker features a 1" Aluminum dome tweeter for outstanding dispersion and clarity. The tweeters are angled so you can direct them toward the listening positions.

FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

StampCast Basket: The T165 features StampCast steel baskets for added rigidity.

Mounting: The T165 a 6-1/2" speakers are sized to mount in standard three-hole and four-hole 6-1/2 applications. They can also be easily mounted in 6-3/4 applications, but because the extra screw holes create an air leak in the larger opening, speaker baffles must be used.

Multi-OEM Adapter: For mounting flexibility, the included brackets can be modified to fit 5x7, 6x8, or 6x9 applications.

Note: The bracket is generic (cutout sized for a 5-1/4) and requires modification before the T165 will fit into it.

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 supplied by Crutchfield for many vehicle applications. It is recommended 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.
