Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
HF (Hifonics)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
800 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.
400 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.
Dual
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).
Not specified by manufacturer
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".
87.25 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.
6.5 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.
Injected poly light rigid
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.
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.
1.25 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.
1.25 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.
1.6 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.
2.0 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.
5-5/8"
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.
10-15/16"
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.

The following review is for MDFS12, which is a part of the bundle you are viewing.

After receiving the Box, I promptly installed it and began tuning my subwoofer and amp. Wow. Not only did the bass sound punchier, which was expected, it sounded much clearer and did not overlap my OEM speaker in my 02 Jetta.
The box is definitely a key component in my audio setup and I would recommend this product to any of my friends looking for this type of product.

Well Constructed, Nice Box

September 14, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

I only give it 4 Stars because I purchased this originally because the specs listed this box as having a 1.25 cu. ft. internal volume. I ideally need 1.25 cu. ft. for my Kicker Comp12. However, this box is 1.0 cu. ft.. The webpage was updated after I received mine. Still I kept the box, put a little more stuffing in it than required to make the sub think the box is even larger.

Other than that the box is very well constructed. I you were using it for a high powered 600W RMS or greater sub I would reinforce of the corner joints with wedges or corner braces for added stability (remembering to subtract the volume of the wedge braces, especially, from the internal volume). Meaning This box would be good for high powered shallow mount subs with a Vas slightly under 1.0 cu. ft..

Good sub for moderate power systems. Doesn't like peak power tho. Went thro 2 of them with 750 watts max. If your going to dump some power into your system (+1000 wats), subs are not the place to save some $$.

Great Enclosure For The Price!

August 21, 2014

The following review is for MDFS12, which is a part of the bundle you are viewing.

I received this enclosure via a package deal from Sonic Electronix with the Infinity Kappa 120.9w. They are a great match! The enclosure matches the subwoofer manufacturer's recommended sealed enclosure size.

This enclosure arrived in perfect condition, with no air leaks. I have tested out the Infinity 120.9w woofer with 600 wrms pounding to bass heavy music, and the enclosure held strong.

The terminals provide the option for banana plugs or direct wire from the amp using the screw down option (which I chose because I have no banana plugs on hand). I may be getting some banana plugs just for easier connect/disconnect.

The fact that the enclosure carpet (black) matches my Lexus trunk carpet perfectly is a nice bonus.

I did add some extra poly-fil - the amount that came with the enclosure was one thin layer around the interior of the box - not enough for my liking. I bought some poly-fill and packed the box half full.

This enclosure should last a long time - it is very solid and well made. I also like that the sides are inset about 1/4", allowing for easy grip when lifting the enclosure.

Keeps blowing me away more and more!

November 6, 2011

The following review is for HFX12D4, which is a part of the bundle you are viewing.

This sub just keeps hitting harder and lower! I'm amazed and blown away! I was underwhelmed for a while there because I realized that I actually killed my previous sub by sending a very strong and very clipped signal to it by having the gain set too high for my head unit's preamp voltage. To reach the ~250W RMS the amp is rated for with my head unit, I need the gain knob LESS than half way up. Any more than that and it starts distorting, and this is not because of the sub but because I'M SENDING A CLIPPED SIGNAL FROM MY AMP. I feel like I've officially made that step from n00b to experienced installer. I had read all the instructions and guides before and never understood what they meant by matching the head unit's preamp voltage. Now I do and I know how not to kill a sub (and/or amp, for that matter).

Anyway, I had never broken in a sub and this sub is STILL blowing me away! It's hitting harder and it does better throughout the entire range. The lower notes (centered in the mid to high 30Hz range) I could barely feel at the start are now making the car have a slow, deep vibration when they hit (remember it's a sealed box). Being a 400W sub I feel like playing it full-blast at 250W RMS is good enough as 'breaking it in' and it is just finally beginning to impress me. It's hitting almost as hard as the Memphis sub that was getting a clipped signal with a few extra watts to compensate for my bass-trap trunk (thick leather seats, kills any bass trying to come from right behind you). Right now I'm keeping my rear seat's backrest down so I can feel the full effect of the sub.

I just can't wait to give it 400W. OMG. What a great sub. If 'you get what you pay for' is true 99% of the time, the HFX12D4 is the 1%, by far!

Pretty good for money but...

March 27, 2014

The following review is for MDFS12, which is a part of the bundle you are viewing.

Overall, this enclosure is fantastic and it is a great value if you didn't want to build a custom enclosure like myself, but there is one thing that is wrong in the description... on both sides of the box, the left and right when looking from the front, are recessed 3/4 of an inch, leaving a lip on both sides that is 3/4 of an inch tall, so it changes the internal volume of the box by a small amount, around 0.14 cubic feet. Not a big difference but for some that is a deal breaker. it does come with a small amount of polyfil, enough to cover all 4 solid sides. Otherwise, great buy! Still worth 5 stars in my opinion i just think they need to be more specific with the outside dimensions.

Side note: the lip on each side is a nice addition and it adds to the visual aesthetics of the box and also serves as a nice place to mount your amp so it sits a little recessed on the box like I did with my Alpine MRV-500 monoblock amp!

The following review is for MDFS12, which is a part of the bundle you are viewing.

I didn't expect much for the Price. I was Pleasantly Surprised. This Box is Well Made. Extremely Well Made for the Price. The Binding Posts are Gold with Decent Quality. The Box has some Batting inside, though I added about twice as much more to it. You could use Slip On Connectors on the Inside of the Binding Posts, but I chose to Solder. This Box is subjected to Lots of Vibration and I didn't want anything working Loose. The Speaker Opening is a Perfect fit for my Sub. I tried to add Sealing Tape to make it Tighter, but it was already so tight that the Sealing Tape wouldn't fit, so I left it Off. I've been driving around for several weeks now and not a rattle. I'm extremely Surprised and Satisfied with this Sub Box.

Seems to be well built. This design is something you could build yourself but for the price its hard to justify the time to build it. I changed to a vented box though and am much happier with my sub now. I listen to mostly electronic music.

The following review is for MDFS12, which is a part of the bundle you are viewing.

i purchased this along with the 12" Kenwood sub-woofer. The speaker sounds great in this box. no rattles or anything like that, built pretty solid and is just a good basic box shaped enclosure. i would highly recommend this enclosure if you are just looking for something simple, sounds good, and if you have the space for it in your vehicle or wherever you intend to use it!

I've had these subs two of them hooked up to a crunch 1500 powerzone amp in a sealed box and they bump!! I've had them for two weeks and still working great! I had a previous set of subwoofers that hit great lows and I'd say that these subs don't hit great lows but they hit really crisp mids and highs :) I love them either way at great price I don't mind I'll probably get a third 12 that mainly hits great lows to even out :)

January 13, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

I love the quality of the box itself. It has held up very well pushing my 12" VVME. I purchased this enclosure because it was the cheapest I could get at the time. However, I am upgrading now that I can afford a ported box. The carpet is a very deep black and the box itself is rather small, granted it is a sealed enclosure with only 1.2 ft of volume. Ultimately, I would recommend this subwoofer to anyone looking for an affordable sealed box that fits in their trunk and sounds great!

Switched to a sealed box for my Alpine Type-X. Much better SQ! Now I can push more power, and have more accurate bass. Box was well built, as described, but contained a minuscule amount of fiber. Not sure how well this affects the box, but I'm happy overall... so it's fairly a minute thing to worry about anyways.

March 26, 2014

The following review is for HFX12D4, which is a part of the bundle you are viewing.

i bought a set of these to replace some blown woofers in my house cabinets. of course after reading reviews i was curious since a lot of people have great things to say. i'm running mine in some older sear's fisher cabinets with decent crossovers ( not sure on specs ) off of a technics 5.1/stereo and in stereo mode i get about 150 watts per channel.

first you have to rip the plastic magnet cover off the back cause i could tell it was going to rattle just tapping on it. i wouldnt compare these to my L5's in my 7 cube ported box, but wow they sound amazing! my wife was amazed, and my brother in law who thinks he's an audio engineer was thoroughly impressed. i can't speak for the sound in a car. if i had them in a car i wouldnt feed the pair more than 1000 watts at most since they sound so good at lower power. if you are reading this i would say do it. buy one or 2 or what ever cause they sound good and only cost 35 bucks. absolutely perfect for house stereo woofer replacement. i gave it a lower ease of use score since you have to rip the stupid plastic cover off right away

I've been a car system fan for many years and had alot of setups. These Hifonics Subs are more than you can ever expect from a low priced subwoofer like this one. If you are looking for a setup of two or more speakers these are the best. Great looking, powerful, CHEAP(money wise) and built to last. I have 3 of them and let me tell you they hit so hard my ears ring. Oh yea one more thing Sonic Electronix - a super glue should come with these subs cuz my rear view mirror fell right off. :)) That should tell you (buyers) that these product is worth of money. Thanks for reading this hope I helped.

The following review is for MDFS12, which is a part of the bundle you are viewing.

Used an Alpine type R 12 with a m500 amp and this box hits quite nicely for it. However the plastic terminal cups that came with it melted and I had to order a replacement. Overall the sound quality is good and hits hard (could be harder so might upgrade to custom spec ported).

The hifonics hfx12D4 is the best subwoofer on the market if your on a budget, yes the price may scare you, you say well with the sub that cheap how could it possibly be true that it sounds to good, well take it from me, i was very unsure of the purchase i made with this sub, i strictly went off of reviews, however, this subwoofer i my home theater sub, it hits. i owned 2 alpine type R 12s, so believe me i know what it means when a subwoofer hits. but the cold hard truth is, this sub is amazing the quality is so precise you cant help but to be cautious. BUY THIS SUBWOOFER YOU WILL NOT REGRET IT!!!

Not Cheap Subs!

March 7, 2014

The following review is for HFX12D4, which is a part of the bundle you are viewing.

These subs may be priced very low, but they kick VERY hard. Almost as good as my friend's Kickers. Of course it's not broken in yet so, I think it can hit harder than the Kickers pretty soon. Bought 2 of these, maxxlink amp wiring kit ($29.99 here), Autotek 1000.2 amp, and a Ground Shaker box ($59.99)! All with $200! Cheap doesn't mean bad. Get a good amp, wires, and box and you're good to go! Trust me, these will not disappoint!

March 12, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

I recently upgraded my entire subwoofer system and this was the box I chose, for the price it is unbeatable. I have a Pioneer 12 inch champion series dual voice coil subwoofer in the box being powered by an Alpine MRP-M500 class d amp running at 500 watts at 2 ohms this combination sounds perfect. I have had many other setups before this. And I bought my current set up the be the end of my car audio line. I could not be happier with everything that I chose. The subwoofer sounds so good in this box being powered by the amp I have the lows are like butter and the highs are not unbearable. I highly recommend this box.

Most people think I have a much larger sub. Great job Hifonics! If you are on a tight budget, do not hesitate to buy this sub.

I recommend this box for anyone who wants a simple, clean, quality built box. It works well and has clean bass in my trunk. It has the bare minumum of poly fil for this box, it wouldn't hurt to add a little bit more since this is a smaller squared box for a 12' sub. Need something to mount it with also.

because of the design or the cage. the plastic cage rattles against the metal right below it. at first i had thought i had messed up my friends subs. then i realized because of the design of the cage it made it rattle. its a VERY easy fix. just go to your local hardware store and get some all purpose silicone or caulk and put it right underneath the plastic cage inbetween the plastic and the metal. let it dry. hook up your subs. problem solved! these are great subs. for the price of the subs i think its worth spending an extra 5$ and putting silicone on it.

one of my FAVORITE subs. they hit NICE AND HARD. i would definitely recommend

The following review is for HFX12D4, which is a part of the bundle you are viewing.

I have 3 of these in a slot ported ebay box in my game den being powered via a Behringer EP2500 amp wired parallel / series for a final load of 6-ohms (meter reads closer to 5-ohms which is a plus). They only have a few hours on them so they are a little bit stiff still. They are the best value out there as far as I am concerned and Sonic got them to me within a weeks time well packaged and un-damaged. Although not a typical installation, they MORE than fill a 1,000sq.ft. room with authority and will do the same in a car. I am giving them about 1,400RMS and they take it all. My ONLY complaint is the connection terminals (spade style). A little bit of soldering is no big deal though, especially for the price point these are at. Very satisfied and would highly recommend them to anyone.

Better than previous model

June 7, 2012

The following review is for HFX12D4, which is a part of the bundle you are viewing.

I have 2 of the older HFi12D4 in one box and two of the HFX12D4 in another, both in parallel, so they took same exact power and the Hfi burned up at around 250W RMS (1000 divide by 4) while these remained unaffected.

They sound great, and even though the HFi12D4 looked prettier with the chrome on the edge, and the nice pressure terminals. This one is better because this HFX12D4 actually outperforms them very slightly AND take more power so they won't blow on you at higher watts!

The HFX12D4 are supposed to replace those HFi12D4 anyway.

These woofers are a good alternative to the expensive competition woofers because they SOUND good and they are LIGHTER so the weight won't drag your car down, especially if you have a sporty car you want to keep weight at a minimal.

They're not as loud as the loudest, but they are great for lower power setups as they sound deep.

I would say they are as loud as any woofers around $100 and below price range, and have a nice bassy hit to them.

I have two of these running off of a 1100watt amp and they sound great! After a while of bumping in your car the subwoofers will give you a headache!

The following review is for HFX12D4, which is a part of the bundle you are viewing.

Not only does it look cool, but it sounds great. Put it in a vented box from Sonic with correct recommended volume spec. I am powering it with an "old school" Hifonics "Odin" amp with 75 watts per channel. It produces "vulgar" bass......For that kind of performance, with relatively little wattage, it is very efficient. It is similar sounding to my Alpine single coil 12 inch. Without a scope, it is hard to tell which has lower frequency response.

I got two of these and they're pretty good for the price. I've had them for over a week now and they do hit pretty hard. I have them hooked up to a cheap nitro amp and it's powering them but for the kind of music I listen to these subs can't really handle it. They're great for country and rock music but not songs with deep low bass.

The following review is for HFX12D4, which is a part of the bundle you are viewing.

I bought 2 of these to go in a ported box. They are currently under powered by about 150 watts or so, but they still hit pretty hard in the back of an 07 Aveo5. Would definitely recommend these to anyone looking for some pretty good bang for the money.
Only one small complaint though, One of the dust caps on the sub started to come off shortly after the break in. Fixed it with some thin compound hobby glue. Other than that I love em'. Also would have been nice to have some different terminals than the ones on there but no big.

April 24, 2015

The following review is for HFX12D4, which is a part of the bundle you are viewing.

I bought 4 of these. One: to replace a sub that I blew. 2: as an experiment to see how well these subs actually are. $110 for all of them, why not? Ill call these subs EXTREME BUDGET SUBS. Baskets are plastic chrome. I have them in a 4-12's prefab separate sealed chambers. I have all each pair hooked up in series/parallel for a final 2ohm load on a RE Audio ZTX 5000.1 amp. According to my amp specs, at 2ohms im getting 1700 watts rms. Using my DMM and OHMS LAW CALCULATOR, I set the voltage so my amp is only pushing out 1600 watts rms. After 2-1/2 weeks of being easy on them to break them in some, meaning keeping volume around 15-18 out of 35.I started pushing them HARD. Volume at 27-30. All 4 are loud as hell. my kids wont get in my car if I put volume at 30. Theyre older teens, NOT YOUNSTERS. My car is a 2007 ford focus 4 door. Playing DECAF/bass songs that have very low notes I dont recommend for ling periods if time. These things heat up quite a bit trying to keep up and I have smelled the voice coils a couple of times. Maybe because I only took it easy on them for 2weeks. I would not recommend putting more that the rms rating through them. ALL IN ALL....im impressed with them for the price. My review is based on the 1 month that ive had them so far and for the price.

September 28, 2014

The following review is for HFX12D4, which is a part of the bundle you are viewing.

My life is littered with Subs of all sizes and brands. I've probably owned 20 different ones, and currently have 4 or 5 sitting on the shelf in the garage. To me, the mostly sound the same, and I've spent $30 to $500 on subs, and they still sound mostly the same. I always like Hifonics stuff, either old school, or newer (Maxxsonics) era, especially their bass equipment.

Built a box for a friend, and decided to try this sub. WOW, just WOW. A great solid sub in general, but for the price, HOLY COW. The thing just slams, and is responsive enough that it can be subtle too. And its not even broken in yet. Powered by a Hifonics Gladiator 1000W amp, the combo is simply awesome. I can't imagine there being a bass section that is better than this.

Now mind you, this is not built like a competition sub, with cast aluminum baskets, 30 pound magnets, and spiders made of space age materials, but it also cost 35 bucks.

You basically can't go wrong with this product. Anyone who complains about the Hifonics HFX12D4 just has expectations that are completely misaligned with reality. Its a bargain, it sounds amazing, it has terrific texture and can handle subtle, as well as earth shattering bass, and it even looks decent.

I looked at these subs for awhile now my cousin got one i hooked it to my 800 watt rms legacy amp no gain in a sealed 1.25 cube foot box and it hit just as hard and my 2 duals do in a bandpass i was amazed on how great it sounded. So i bought my self 2 today will be switching out the duals for these. Get these if you are tight on money they will hit harder then kickers if you know what you are doing.

Cheap Price = Cheap Sub

October 26, 2012

The following review is for HFX12D4, which is a part of the bundle you are viewing.

I bought one of these subs just because I already had a ported box that fell within the recommended enclosure requirements. 1.8 cu ft tuned to 35 hz. First of all, the sub looks good from the front. the rear looks kinda cheezy. Its lightweight. OK construction. Installed in box. Noticed a rattling sound just moving box around on shop floor. Turns out to be the magnet cover. Tried it anyways. Powered it with a PPI Sedona 550.1 which should be perfect for this sub's rating.

The rattling sound got way loud. Immediately removed sub from enclosure and ripped the magnet cover off. That helped with the funky noise.

The sound output of this sub is pretty good for rock. If the box is tuned say around 40 hz, it should slam pretty good for the price. However, when the lows kick in, this sub falls off BAD!!!! Not good for Rap or Hip Hop. Sounded like it wasnt getting enough power, but I know it was.

All in all, not bad for the price, but not good enough to warrant purchasing again. Not really worth the time and effort to install these subs. Just a cheap experiment for me.

The following review is for HFX12D4, which is a part of the bundle you are viewing.

Have had everything from W6,TypeR,Comps,CVR,IFINITY,VEGA IT,MTX 8500,ECLIPSE,RF P3,TypeS,TypeE,Coustic, W3,and more, got these ones on EBAY $48 pair and a Boss 1600/2 As I was unemployed and needed my bass fix on a broke man budget was a sceptic.I had them about 1/3 gain to break in at 2OHM. They have better than impressed me for price.Only issues as most people have said on here is crap terminals and plastic dust covers.I Put two in a Obcon labyrinth dual slot port box with 3/4 spacer for extra Cu.ft they Hit HARD. Almost better than CVR'S. EITHER remove or glue plastic basket and DON'T over power & take time break them in. I now have them mostly up on gain just trying to fine tune the bass on my Kenwood Excelon 397 is at -6 and they RUMBLE THE S*#@ out of my 2001 TAURUS. I order another pair so I can run a triple and at $75 for three it will out perform setups TRIPLE in cost. my deck cost more than subs/amp. If you Take time hook up right break em in and tune I have no doubt they will perform beyond expectation.Would probably be best uf have extra $$$ run RF 400/2,KICKER 400/2, Alpine Mrp 500,JL 360/2 OR 500/1(not slash), other wise a cheaper 1500-2000 watts monoblock or 2ch will match best for 2 of these. Watch EBAY AS WELL can get Boss/Power Acoustik/Planet Audio Etc. in that wattages around $60 and the other Namebrands Around $100. I just scored a power acoustik BAMF 2000/1D @ $93 to run three of these should push and not overpower giving a long life(longer than I will have them)

I have a 15 inch in my Yukon and wanted more db's to pound my chest. After reading many positive reviews about this sub, I decided to give it a chance. I purchased it with the 1truck12 box and added about 6oz of polyfill to the box. The sub does not come with push terminals but I do not mind. It looks good and is built surprisingly well for a $30 sub. I wired it to 2 ohms and have the whole circuit wired to 4 ohms. Boy oh boy! I feel it in my chest now! I have significantly deeper and louder bass! 2 or more of these sub's will shake your ride and make you smile. Thanks Sonic :)

The following review is for HFX12D4, which is a part of the bundle you are viewing.

Right out of the box and into another box, lol.
I have it hooked up to an alpine mrp-m500 amp with the gains corectly set then pulled back a little, as I want to have even amounts of bass in comparison to the other speakers. This sub sounds excellent, I know you get what you pay for but this is too good! The sub hits hard and clean and can handle the s*** I give it. I have the sub wired down to 2 ohms at 500watts, which is the happy max of my amp. It handles the max power without issue.
The only drawback is that poorly affixed cover on the magnet, some frequencies make it vibrate, but it can only be heard when my trunk is open and I have my volume past 70%. Solution? Tape wrap your favorite tape along the gap between the cover and the chassis of the speaker. Viola best speaker ever! You don't get this quality at this price anywhere else.

I have one of these in a sealed box and it's getting 600 watts RMS. It hits the lows really good, sometimes the highs hit hard, but it could be a little cleaner. In my single cab truck it fills the cab with nice clean bass. Just the highs could be better. Haven't tuned it properly cause I havent had the time, just wanted the system in quick for a long trip. I'm upgrading to two 15's so then I'll take the time to tune it. But even for how it is quickly tuned it sounds great.
