Speaker Specifications

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.
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 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.
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.
195 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.
65 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".
90 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).
35 - 21000 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
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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
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.

Kicker KM654LCW

May 12, 2014

Waited FOREVER for these to come out! Installed 2 pair in our brand new Avalon Catalina boat. I used a 4 channel Hifonics Zeus 600 to push them. Sounds great and you can hear them at full speed with wind in your face! They look amazing lit up.

Pro's: Great sound, awesome lighting display with many variations and colors. Great addition to any boat with existing LED lights! They strobe, pulse and stationary.

Con's: The $40 remote is sold separately and is a must if you want to turn them on and off and change display. I don't know how the speakers work without it. Way to expensive at $174.99 a pair. Wiring instructions are not real clear and quite extensive (6 wires per speaker)

Great Sound!

June 1, 2016

I bought these speakers to use on the tower of my wakeboard boat primarily because of their price, but had also found a few reviews on-line stating they had good sound. I hook up two pairs to a Wet Sounds HT-4 amplifier and they sound awesome. Solid midbass and highs. So for the price they exceeded my expectations, not to mention they come with white and charcoal grills to match your interior or tower. I have not hooked up the LED, but hope to do so in the future. And of course, Sonic Electronix came through with a good price and quick delivery.

The LED lights add a cool feature.......and the speakers perform well.

Do these come with both grill colors of white and grey?
Chief on Feb 11, 2015
Best Answer: Yes they do but go darker looking white grills sent to me that i did not like. I bought 4 pair and two of them came in really good white and the others came in darker white for some reason. Luckily i am using the darker gray for all of them but if you are not beware of the white ones.

are these waterproof or just water resistant?
scott k on Mar 14, 2016
Best Answer: They are waterproof as far as rain, splashing, hosing down. You want to create the best seal between the frame and whatever you are mounting the speakers in for audio purposes.. It will also help avoid corrosion. I wouldn't submerge them if that's what you are asking.

Is there a way to have them only one color and not change? Also how do you control the different speeds of lights?
Philthy on Oct 12, 2015
Best Answer: Yes, you need to purchase the remote control. was around $35. there is an adapter to hook up to the wires
when you use the remote control. make sure to follow the wiring instructions with the remote and speakers for the LED can control and speed with the remote. I think the remote is a must have if you really want to enjoy the speakers.

could you put these in a jeep wrangler?
Thomas M on Aug 18, 2014
Best Answer: Hello Thomas,

Absolutely. As long as the location accepts a 6.5". You may at the very least need a bracket, like the Scosche SAC656 , or at the most have to modify the panel. Point being, not impossible, just out of its made application.
