Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Chaos Exxtreme (Boss)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
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.
400 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.
200 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
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
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).
40 - 4,500 Hz
Sensitivity
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
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
2 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
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.
Injection Molded Polypropylene (IMPP)
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.
Butyl Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.6 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.6 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.65 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.65 cubic feet
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.
3-7/16"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
7-1/16"
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.

grill covers fit perfect

September 22, 2011

Custom built one inch for cabinets and using bpt60 tweeters grille covers fit perfect over this sub because of the way i put together the boxes these speakers will never need an amplifier to drive them.

Great price , excellent subwoofer

April 19, 2011

It might only be a 8 inch subwoofer, but it can handle alot of power. The magnet is not to big so you can fit almost anywhere. Surprisingly for the price it is marked at, the sub is made pretty well. Would fully recommend it to any one replacing there factory sub or to any one who wants just that extra kick, but nothing to extreme.

Cheap and SIIIICK

March 24, 2011

I bought this speaker when it was on sale for around $20 with shipping. I put it in a small ported box with a 300rms amp and this thing sounds really good. I wasnt looking for extreme eargasm bass just some fuller sound and this sub hits the spot. It has a nice range even hits the lows on most songs without a problem. Overall a real nice speaker for its size and price range.

Great speaker at an unbelievable value

February 28, 2011

This fits perfect in my 99' Ford Expedition. Should fit most other years if you take some time to fit it to the sub box. Sounds like a much more expensive speaker. Six months later and still going strong. Why pay more.

Good factory replacement

December 13, 2013

I bought this as a replacement to put in my 2001 expedition factory sub box. Fit fine just need to drill new holes. I do have a small FLI amp supplying the power. I would recommend for the cost and the small depth to fit in a factory sub box. I have owned this for over a1 year no problems, it's used daily.

Great little subs

September 17, 2013

These little subs are great, so much power from such a small unit. Puts the old 12 in sub to shame. Would happily buy more and install in future cars and recommend to others who want big bass and be able to use their boot too.

are you serious?

December 8, 2012

for anyone who gives this 8" tweeter a 2 star or higher rating has never heard a good subwoofer in their lives! My 3" mids have more bass output than these worthless subs do. Like all Boss audio equipment the best place for these is the garbage.

decent for mid bass

June 7, 2012

This sub is ok for mid bass, but it just can't deliver a good hard thump that a good quality sub can. You do get what you pay for. The coil in this sub is small. Like 1" small. I do not recommend that they be ran at high volume for extended periods of time. They can't handle it as well as a big name sub, but they are a decent sub for mids on low key power.

Good Sub for the Price

April 19, 2012

I used this sub to replace my Ford Explorer Sport factory sub that had dry rotted. The factory sub was a little bigger, but this sub still fits. You just have to drill new screw holes, and use a bolt, fender washers, and silicone to cover the rear mounting hole in the plastic sub box. 6 months and still going strong.
