Superior materials

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 reproduction of the lower and midrange frequencies, while the 3/4" aluminum dome tweeter makes the high frequencies sparkle. These speakers will handle up to 40 watts RMS so you should use an amplifier to get the most out of them.

Rockford Fosgate innovations

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 than the average 4" speaker, and it's supported by a durable rubber surround that's designed to last a long time. Open slots on the frame make it easier to install these speakers if the factory holes are slightly off.

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research

Features

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.

CEA-2031 Compliant: Power handling conforms to CEA-2031 industry standards. This means the speaker has the capacity to handle its rated power under continuous demand, not just for an instant.

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.

Tweeters: The 1" Aluminum dome tweeters are mounted at an angle, so they can be aimed for optimum imaging.

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 T142 features StampCast steel baskets for added rigidity.

Multi-OEM Adapter: For mounting flexibility, the included brackets can mount the T142s in many 5x7 and 6x8 applications.

Note: The bracket is generic and requires modification before the T142 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.

Q

We don't have a way to mount these into either audio system that could have come in the car. The mounting pattern isn't a match and there isn't enough room for them to fit behind the stock grill. My Bio: https://www.crutchfield.com/bio/Paul

Q
Do these come with speaker grills?
[ Nicholas  Oct 15, 2016 ]

A
They do not, no. You can see what comes in the manufacturer's packaging by scrolling down the speaker's main webpage to the "What's in the Box?" section. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5
