Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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
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.
400 watts
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.
1200 watts
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.
Elastic Polymer
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".
93 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).
20 - 125 Hz

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Easy Inexpensive Bass Upgrade

March 15, 2015

I wired this in place of the stock "subwoofer" of the B&O system in my Audi. It takes up very little trunk space, matches the look of the interior and makes an astounding difference in the overall sound of the stereo.

For just over $100, it's a no-brainer. I'm sure it would sound even better with it's own amp, but see no reason to go to the trouble.

Note that the stock speaker is 8ohms and this one is 4 ohms. Doesn't seem to be an issue, but be aware.

This sub hits HARD!

December 20, 2014

I'm very happy with this woofer. It hits hard for a shallow mount as long as you get a quality amp to power it! This sub SLAMS when it is paired with the Pioneer amp GM-D9601. The amp makes a huge difference, and don't make the mistake of buying a cheap amp to power it.

Perfect for small vehicles

November 8, 2014

This sub hits hard! It fits perfectly in the back floor of a Supercab ranger, takeing up very little space.
It sounds fanastic, it can pound along with a rap/EDM song and shake the truck, or dellicatly recreate a acoustic upright bass in classical music.

All over a great value for the output. it really fills out my system.

Time saver

I bought this unit because I didn't want to spend the time building a box for the trunk on my firebird. It has just the right pop that I was looking for. It was a perfect fit sitting right under the package tray. Couldn't be happier.

Excellent Bang for the Buck and placement

August 13, 2014

I have had many JL stealthboxes in a few different cars and they have all been amazing! but on my vw GTI i didnt want to pay that kind of cash (600+) I dropped in an amp with a built in line convertor and ran a JL 12" in a ported box. Of course sounded great with tons of thump. Problem is i lost all my trunk for one sub...........

Ran across this sub enclosure at an amazing deal shipped and had to try it. Most reviews online that say this sub sucks are for the lower 400W model which looks identical to this one. This higher end version is PERFECT, runs excellent additional low end to my stock HU. Plenty of thump and i have my bass knob turned only a quarter and it bumps really nice and loud.

The best part about this sub and the main reason i bought it, is it takes up almost no space. And if i want to stack stuff on top of it i can easily because its down firing. If i want to fold the seat down and really use my hatchback space i just prop it up on its side and have almost all my trunk space. WORTH EVERY PENNY.

Works so well i actually have 3 friends who bought the same enclosure to put in their cars after hearing mine. One friend actually took out his spare tire in his mazdaspeed 3 and this enclosure fit perfectly in its spot.

Had it for a month and so far so good, great product.

This woofer gives clean deep rich bass that isn't overwhelming. By this I mean it adds great sound quality for the occupants of the vehicle, not others walking down the sidewalk.

Nice SubWoofer

January 19, 2015

I purchased this for my Silverado 2014. It turns out it does not fit. It is too big to fit under the back seat. I don't know what I am going to do with it now. It sounds great and I would love to mount it, but for the moment, I am stymied with it. I rated the ease of use lower because it wont fit. Not the product fault.

Small Size, Big Performance

September 18, 2014

Small enough to fit under or behind the back seat of a pickup truck while delivering big sound, clear enough to feel the bass without the window vibration of other subs. This can only be accomplished after some adjustments of the amp and head unit. Be patient, it takes a little time to find the right settings. This is a down firing sub which means it doesn't bounce like your regular subs but it sounds great. Hook it up with a mono amp so you can get the most of it. If all you want is a powerful sub with clean bass, this is a great choice.

Does this sub come with an amp.?
Browning B on Oct 27, 2014
Best Answer: Hello,

No. The SWX2502 is only a "Loaded Enclosure", not a "Powered Enclosure". The sub will need an amp providing ~400w @ 4ohms, like the Kenwood XR600-1 or Pioneer GM-D9601.

Does this sub woofer need an amplifier paired with it because it shows up as a loaded sub enclosure which means to me that its ready to be wired up, no need for an amp?
Roland B on Sep 5, 2014
Best Answer: It actually does need an amplifier. "Loaded" in this case means it comes with a subwoofer. We do have a selection of "amplified loaded enclosures" which you can find here:

Would this fit properly in a 2000 dodge Dakota single cab without sacrificing seating room?
A shopper on Feb 17, 2015
Best Answer: Not 100% sure. I mounted mine under the seat of an F-150 bench seat for some thump in the rump.. I used the measurements on the Website & then measured my under the seat clearance. A little tight, but made it. Keep in mind that a Bass Speaker isn't directional, so it doesn't really matter wear it is installed in the cab, as long as it is firing into the Cab. Hope this helped.

I would like to know what the internal volume of the enclosure is ?
Timothy M on Jan 5, 2015
Best Answer: I drive a 89' s10 Blazer. I have my Pioneer paired up with a 300w rms Jensen amp. I am very impressed with the sound quality of my set up. No matter what type of music I listen to it hits hard & clear. It's perfect for me because I don't like my bass to overpower the music. Hope that helps. I do recommend that set up for my friends.

Hi I'm planning on ordering the Pioneer TS-SWX2502 with the Pioneer GM-D9601 amp. If I order it with the NVX XKIT42 amplifier wiring kit that is everything I would need to set this system up? Also is 4 gauge wiring to big for this system?If it is what is the next smaller alternative within the NVX kits i should get?

Best Answer: Hell Austin,

The XKIT42 provides all the basic IMPORTANT parts to install the amplifier. No two installs are alike, so there will always be the chance that you will need a random connection not included. This seldom happens, but plan accordingly to make sure you have access to parts.
In regards to the Power/Ground Wire, the 4 Gauge will insure that the amplifier runs VERY happily throughout the duration of its life. However, the figures you plan on running - i.e. ~400-500w RMS - technically only calls for 8 Gauge OFC, like the NVX XKIT82 .

Yes, this is a good match. The figure match perfectly. Keep in mind, the amplifier will need to be bridged to provide the needed power and matching impedance .

Will a Hi Phonics brx1200.1d mono be to much power for that pioneer? And will the box fit behind a standard f-150 cab seat?
Robert b on Jan 13, 2015
Best Answer: Hello Robert,

No, its a perfect match. The SWX2502 is asking for 400w RMS @4ohms, and the amp is providing 450w RMS @4ohms , making it a perfect match.

Unfortunately, we don't have the available dimensions for 'behind a standard F-150 Cab Seat', but you are free to measure the dimensions and compare them to that of the enclosure: 13-7/8"D x 18-5/8"W x 6"H .

Best Answer: Hello Austin,

You will need far more than just an RCA cable and Speaker Wire. You've got to be able to turn on/off the amp, get power to it, ground it, etc.. The easiest way to accomplish this is by picking up a Amp Wiring kit like the T-Spec V8-8RAK, which will have everything included.
