Speaker Specifications

This is the manufacturer product line of speakers.
Prime (Rockford Fosgate)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Component System
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Mica Injected Polypropylene (MIPP)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
80 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
40 watts
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
89 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
60 - 20,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/16" x 5-1/16" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Love them!

December 11, 2013

I purchased two pairs to replace the stock OEM speakers in my 2002 Corolla S. I was blown away by the sound, excellent highs and good mids. I have a sub so I can't say much about the bass they produce. I have these powered by an Rockford R400-4D amp so they are getting at least 65 RMS each. No distortion or hiccups at any volume. Great great speakers for the price.

Sweet Speaks!

May 15, 2013

I replaced the OEMs in the doors of my 03 Tundra and was very pleased with the difference.

I am only driving these with my Sony (always excellent signal to noise ratio!) media head unit but they put out plenty of sweet and clean vibes!

For the price you can't beat it.

April 15, 2013

Installed in a Hyundai Accent 2010 4 Door sedan.

Installation was quite easy in general fitted in OEM 6.5" speaker bracket, just had to create a hole that wasn't there since the bolt pattern isn't the same which is not a big deal.

High and med are great, a little too much of high actually, would have hope for a little more bass.

Also i would have wish to have more option to install the tweeter in place the little stopper that came with it is almost useless, used the stopped + nail glue to stick it in place correctly.

Very good for the money

April 1, 2013

These are very clean door speakers and get pretty loud, I mean they are not the best out there but for the money they would beat everybody in its class, I bought then and installed them in my buddy's truck and they play really nice highs, I would recommend you buy a subwoofer though to complement the sound because, in the 6.5's, the mids are not ground pounding lows but all in all very good clean door speakers

Fresno, CA

Great sound and value

March 24, 2014

The price in the stereo shop was $200 a pair, I paid only $130 for two pairs here. You can't beat that. I have a Prime Rockford Fosgate 4channel amp running it and it sounds great.

Pride, LA

Awesome Speakers

September 26, 2012

I have had these in the front doors of my 01 Silverado for several months and they sound great! I had them running off the stock radio and they were decent sounding for a stock radio. Then, i installed a Pioneer head unit and a KTP-445 Power Pack Amp behind the dash to give them 45rms each and they sound amazing! Dont think that Rockford's lowest line of speakers is junk, they are no joke.

if I installed a bass blocker on the wire going to the speaker will that help the woofer?
matthup on Dec 20, 2014
Best Answer: "bass blocker" is somewhat vague, I'm assuming you mean some sort of device that removes the low frequency sounds from the signal. Your question, "will this help the woofer" really this depends on what you are going for with your audio system. If you have a subwoofer installed, doing so would help the overall sound of your system. Separation of frequencies to specialized speakers is what gives you the best sound quality. The way I suggest achieving separation for an audio system is by using a head unit with good crossovers built in, along with crossovers on amplifiers. If you have for instance a stock audio system that has no subwoofer taking the bass off of your door speakers won't do you much good. If you have a subwoofer then you want to go for the separation though. I normally don't encourage using add on inline frequency devices, it adds another point o failure, and another point of complication. Ideally you want a head unit and amplifiers that meet your needs. I hope my answer helped you understand a bit better, and in the future if you give more specific information about your entire audio system you will likely get more detailed and helpful responses.

Do i need a crossover for the tweeters?
AudioTech P on Nov 18, 2014
Best Answer: Depends, if the system you are putting it in allready has a stock component system (like for example my 2008 Silverado has stock woofers in the front doors and stock tweeters in the a-pillars) then you wont need one cuase the vehicle allready has one built-in. However if your replacing a co-axle system then you will need to install a crossover. These speakers are great sounding and ideal for upgrading a stock component setup so that's why they are sold without a crossover.
