2011 Pioneer A-Series Car Speakers
Improving on the previous design of the Pioneer A-Series speakers, the new 2011 Pioneer TS-A1304C prove to be a big step forward for the already award winning speakers. The most notable improvement on these new speakers is the enhanced power handling of the speakers. With an RMS power handling of 35 watts. The Pioneer TS-A1304C becomes a great solution for a factory replacement speaker. However, Pioneer increased the Max power handling to 300 watts, which is great for those that want to power these speakers with an aftermarket amplifier. Using Carbon graphite IMPP interlaced aramid fiber cone and an elastic polymer surround, the diaphragm response is smooth and results in natural, crisp sound. For those that want the latest in car audio loudspeaker technology, Pioneer is an excellent choice and a leader in the mobile loudspeaker industry. Improve your ride for 2011 with the Pioneer TS-A1304C.

Speaker Specifications

This is the manufacturer product line of speakers.
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.
Soft Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.
Carbon Graphite IMPP Interlaced Aramid Fiber
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.
Elastic Polymer
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.
300 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.
35 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).
28 - 29,000 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, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-3/4" x 4-3/4" 
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.

2002 Impreza Front Speaker Upgrade

January 11, 2013

There was a lot of mixed information on what size the stock front speakers are in the 2002 Subaru Impreza. Most sites say 6 1/2" speakers and some 5 1/4". Sonic suggests 5 1/4" and I went with these.

Once receiving the speakers and taking stock speakers out I see why there is confusion. The actual working speaker size for the stock speaker is about 5 1/4" but it has a large flange.

These speakers where undersized and 6 1/2" would have fit better but without amp this is sufficient and later I will move them to the back.

Sound - they sound amazing, good tight base sound and the tweeters are just awesome and really liven the sound. I feel like I am listing to music live. I can hear the drummer hitting the symbols like he is in my car. The speaker sound is good at low and high volumes without distortion.

Great speakers and would buy again for sure. One thing that impressed me was Pioneers website information and car fit information.

Great build quality

June 7, 2011

I installed these in my co-worker's 2001 Pontiac GrandPrix. These speakers fit in the factory speaker hole very well. I was worried about how I was going to fit the tweeter into the sail panels the housed the factory tweeters. It turned out that the new tweeters fit in them almost perfectly. Just a hair difference in diameter (smaller). So I made a gasket from electrical tape and they fit perfectly. I taped them in to finish the install. Not too professional I know but I don't think they're going anywhere.

As for the sound quality. They sound nice but they are a bit on the faint side. I think an extra amplifier would help them out but without one they are kind of quiet. Don't get me wrong, when you crank the volume the take everything you can through at them but at low levels they are weak. I'm not hating on them though I think it's just a power issue.

My beef however with these, is the mount-ability of the tweeters. They have very few few options (i.e. screw holes in the mounting cups). Pioneer doesn't provide many tips on how to use the limited mounting cups. I found that to be very frustrating.

Perfecrt BMW 325 upgrade

December 11, 2011

After installing a new Pioneer head unit in my 1995 325i convertible, I discovered my left front speakers were dead, so rather than pour a lot of money into OEM parts I got these, and they are great. They fit perfectly, the tweeter actually snaps into the OEM speaker grille. I just bypassed the factory amp, and ran wires to them. The biggest obstacle was overcoming all the quirky BMW hardware. All for $60, less than half of what a couple new BMW midranges cost. When the amp or rear speakers die completely, I plan on doing the same to replace the rear speakers.

Nice little set of speakers

February 5, 2011

I bought these to replace the factory front speakers in a 2002 Chevy Suburban. They are the same size, but the mounting system is an annoying proprietary snap system (I got around this by simply taking the old speakers off the plastic rings that snap in, drilled holes in the plastic snap rings, and mounted the new speakers to the rings, and snapped them back into the factory holes. I should note that you can not install these speakers normally on these vehicles, they are too small, at least a 6" is necessary to install using the traditional method.) The factory amp/head unit has a set of wires for both the tweeters and the woofers. Don't even worry about the tweeter wires, just use the wires that come in the box and connect them to the woofer wires.

In regards to sound quality: These speakers sound great, especially compared to the factory ones (not very hard to beat.) My only complaint is that at lower volumes, the lower midrange frequency response is very low. Once you turn up the volume a little they start to really shine. This may also be due to the factory head unit that I am using. It is not very good really, but these speakers do help it to sound noticeably better.

What I would do if I were to buy these again is just skip over the 5 1/4" and go straight for the 6 1/2". I only purchased the 5 1/4" speakers because that is the stock size, but after looking around some more, I have noticed that nearly everyone just gets the 6 1/2" speakers, and they do sound a noticeable bit better. (To get to the point: spend the extra 10 bucks on the 6 1/2" speakers. It's worth it.)

Perfect BMW replacement

October 30, 2011

Used these as a replacement for the front doors of my '02 bmw 530i. These are a perfect size and sound great, however you do need an amp to drive them, they are weak without the extra power as noted. Using a JVC avx-k640 head unit and it works but the sound is definitely expanded with the power of an amp. As a reference I used Kicker ks525's in the rear deck and they are definitely louder with all things being equal, but the component set-up allowed me to put the tweeters in the factory sail panel and they fit exactly right. Again let me re-iterate, they will sound better than stock, but they will sound great with an amp, they need the power!
