Hifonics  HFi12D4

if your buying your first subs like I did when i got these, you will be very happy with every penny that you spend on these bad boys i was and still am. i have had these subs for 4 months strong now.

worth every penny got it hooked to a Hifonics TXi5006 and the thing bang real hard louder than my friends 12" alpine R that is hooked to a kenwood amp with 900w rms

I have two of these subs in my truck in a 4.3 cubic ft box sealed. And lets say they hit very hard. I am running a Crunch 1200 watt amplifier on them. I really recommend this sub if you are looking for a budget system but you want to hit just like the others.

I've had several different system such as;Kenwood,Rockford Fosgate,Orion these are all good subs. I installed two of these subs in my car and I was surprised I have them in a sealed box they hit really hard and price was unreal. Im very happy with the results

i have three of these subs on a 1300 class d Sony amp and man do they hit hard. i didn't think these subs sound as good as they do! if you're looking for some hard hitting bass at a cheap price, these are the subs for you!

I have two of these in my car with a 1200w profile amp in a ported box and these things hit hard. A lot more then what i expected for the price these subs are great.

i had 2 of these hooked up to a GP2350 amp. not a bad set at all, did alot more than i expected. they can take a bit more wattage then what they are rated for but not too much. still a good solid entry level sub.

Just got 2 of these in. only got them gettin 150 watts each at the moment. im in the middle of puttin 4 of these in a wall in my jeep, and gettin 2 1000wX1@1ohm hifonics amps, and jus 2 on 300watts is load crisp and clear, sound quality is great got them in a box w/5.2FT^3 slot ported to 29hz, great product cant wait til my other 2 get here!

jus got 2 more of these, totalling 4 now, fricken LOUD in my jeep cherokee. 2 is all ya need for some nice sounding bass though. wont be dissapointed if jus lookin for massive bang for buck!

i have 4 of these and im bout to do 4 more they slam i have 4 of them on a 500/1v2 and it beats

I HAD 1 OF THESE IN MY HONDA PRELUDE, AND IT IT SO HARD!! SO I GOT 1 MORE TOTALING 2 OF THESE. 2 OF THESE CRACKED MY BACK GLASS IN MY CAR! GREAT SPEAKERS!

these are good for the price, hifonics def comes out witht the best speakers.. i got 2 of thes and 2 power acoustic fubars hooked up on the 1600 watt super class d hifonics amp wired at a 2ohm load and it hits.. i'm order 2 more fubars tho and get another hifonics amp so i can have all the speakers at 1ohm

I have 2 of these subs in my 88 Mazda B2200, I am pushing them with a Kenwood KAC729S, I am running 2 channel at 2 ohms. These subs are awsome! My brother has 2 of these in an 85 S-10 with a Crossfire amp running 2 channel at 2 ohms and his hits alot harder than mine. I think they can handle more power. I will be upgrading my amp to HiFonics soon!

Just got this sub after blowing a Boston 12" G2. Running 500w @ 2 OHMS Alpine V 12. Sounds loud at less then half turned up not as accurate or clear as the Boston, but loud and for 35 bucks can't beat it . Iam gonna let it break in a month then crank it so hopefully it will last. OCS awesome job huge selection fast shipping great store thanks homies

i have four of these speaker they do pretty good on my power acoustic 1920 for the price i paid for them i paid 20.00 a piece for them at car discount stereo and they are thesame speakers .

I bought four and just hooked up one to see what it sounded like before I built my box. Ran it with a PG tantrum 1200.1 with about 1600 watts rms @ 4 ohm and the gain at about 1/8-1/4. It was in a small sealed truck box in my 91 Silverado with the bass on both the amp and deck near zero. Let me say for $35 these things slam. Need to build my box quick!

Bought one of these subs. Hits decent for the money but is not the most durable sub. If you plan on going over the rated RMS wattage you will eventually blow this sub. It is very finicky and will whine at you when turned up at a decent level. Other than that it’s ok for a beginner sub.

i have four in my explorer with 2 RF p550.2's in a almost 11 cubic foot box. all i can say is RETARDED KNOCK.they are loud as hell.

i bought two more of these so i have four total on a power acoustic 1440 brided down to 1ohm the low bass that comes out is unreal defintally worth the money

im running 3 of these 12s with a autotech stealth 550. they sound good until about half power and the distort and break up. i would spend a little more money and go with a better hifonics

Well i have 2 of these in my Grand Prix on a 350 watt Crewn Vega amp in a 3Foot Vented box and they are hitting 136 db i will love them till they blow

i have 2 systems using these subs 1 is a single sub in a bandpass box in an explorer with a boss amp the other is 2 subs in a sealed box with the 600 watt 2 channel zeus amp it pounds

i have 2 of these subs in my 2000 dodge neon, i am pushing them with a hifonics txi 6008, and i got to say these things hit some rediculous bass. i've had kicker, jbl, fosgate and mtx in the past. hifonics is the best i've had.. and great price

I have two of these with a ported ground shaker box and a crunch 1600 watt amp in my 97' Honda Accord these subs a loud as heck, they hit like an 11' sub, nail the high notes, and my neighbors don't sleep when I drive past.

bought 3 of these for the tempo, hooked them up to a phoenix gold 1200 mono amp. sound great. loud bass tickle the ear.. u can tell when u go up to loud cuz they start to distort...but for the price you cant go wrong even if you blow them showing off.

i have 4 total bridged at 1 ohm each on a crunch 1100.2 and it hits HARD, well worth the 250 for the subs and amp

I have 6 of these being powered by a MTX 81001 in a 2002 blazer an im very impressed..they handle a little more power but not to much...good think they are cheap just incase u wanna pour the power on

i go 4 of then on 4 4000 watt power aqustic in a sealed box in a extended cab s10 the slam but in goin 8 i cause i need more

I just made a custom box and put two of these subs in my extended cab s10 and the next morning I played them and my neighbor came outside and told me to turn them down because he could not hear the news. For the money you can not pass up this deal. I have dealt with a lot of stereo systems before and for as cheap as these subs are they are well worth the money. Right now I only have a 200 watt rockford fosgate amp hooked up to them because I got it for free and wanted to see if the subs were any good. Very good beginner subs. If you are looking for more I would highly recommend the Brutus Hifonics B12SQD4 and bridge them down to one ohm they hit very hard, But I would recommend this subs to someone on a tight budget.

Dude I have 4 of theses in a extend cab 01 z71 on a JBL 2000 and da windows keep fallin off track its beat so hard i've got 3 tickets but I keep it turned up

2 of these in a Bronco II with a Crunch 700.2 will bring tears to your eyes!!!

I have 6 of these subs wires to 2.67 ohms (3 left and right)on a visonik amp (3909 1600 wts)with a alpine 9831 head unit and 2 alpine 4x6 plates in dash ,4 clarion 6 1/2 in the doors and 2 6x9s in the rear with 4 jbl 100 wat 2 channel amps for mid and high in a 98 S-10 blazer 4 door with two 1 farad streetwire caps and the subs are awsome and at 35 dollars each i couldnt resist! 210 bucks and i have a stereo that i have always wanted,i have had no problems. the sound quality is perfect!

great powneds hard in the right box with the right amp and the right headunit great sub for the price cant beat it

Have 2 of these D4's hooked to a 1000W Kenwood 2 Channel 7204 Bridged at 4 ohms in a ported box. Pushin 500 WRMS right now and it sounds great even at high volume.

I have 2 of these and i love em had em in my old firebird and they used to love knocking the rear view mirror off they and now i have them in my camaro and they hit real hard and do not distort i have each one running at 300w rms in a sealed enclosure best subs for the money period great look great sound and great value

Great for the money actually quite incredible however i recommend if you buy these to also get the Hifonics Txi6006 amp,sounds great with it probobly stickin with hifonics from now on

for cheap subs these rock have 8 in a bandpass box in 99 s/10 one audiopipe 3000 watt amp and is so loud makes your eyes water very good for money

i have 150 of these in a retired school bus and theyre powered by 10 kicker warhorse amps, man these things are so nuts dude i freaked out and turned it all the way up and i killed my biffle. my bad now im in jail i hate these subs they killed my bestie sadface :(

For $35. cant beat it. They sound great. Small sealed box.

i bought 2 of these to replace my subs when i blew 1, and i put these in a ported box and got them on a rockford 1000w amp and i swear they pound serious very little distortion when at high volume but im talking about rediculous high volume, so if u just need a quick replacement or are a beginner or entry level get these they are worth it in the right box

I have one of these in a ported box. Great buy and the sound is alot better than my friends sony's. The bass is tight and they go low. You can really feel the bass. Thumbs up.

I have 6 in my 2002 Chrysler Concorde being run off of 2 MTX 7402 Amps. Love the bass it produces and makes it well worth the money

i got 6 of em for 210 hooked two of em up in a box i had two memphis pr 12s and they almost hit as hard but i dont know whaat to do about the vent on the motor its plastics and rattles only complaints all this bang for $35

I have a pair on an a old skool Orion hcca 225 amp @ 1ohm hits well in a seald box, you cant beat that price.

i never have used highfonics before, i just bought them not know any thing about them one thing i can say im impressed,i have 2 12 hf in a sealed box in a 96 honda accord,on a 500.1 kicker amp mono block,they sound great,best bang for the $$$,for the price u cant go wrong,u dont need a big amp,just do ur math,for under $230 u can have a hell of a system.a kicker 500.1 mono push great.u can get a kicker 500.1 for $120 two subs for $70 box 25-35,ur ready to go.

I bought 3 of these. Put them in a 6 cubic foot sealed custom box. Infinity 1600 watt Monoblock wired in a series down to 2.7 ohms. And It slams I am getting roof flex and door flex like mad and havent tuned the amp to its full potential yet so it will get louder. The subs are great slam harder than anybody in my area at the time so I would say A+++. You can see them on youtube. U will not be disappointed. http://wwwtube/watch?v=WumrdALZ7pA

I had two of these Hifonics in my 1999 Merury Cougar in a sealed box, hooked up to a 1000 watt amp, they hit pretty hard, I would say for the money they are great subs. They are super lightweight too which is always a plus.

this is a great deal!! this is the best sounding speaker for the price i have ever bought, and i have bought a lot. i was running jl wo10 and sound quality was great but the low power handling led to clipped voice coils. i bought this as a cheap replacement just for right now, i dont think im going to need to upgrade. im running it in the same 1.25 cft ported box the wo's use witch is a little small. but i preffer this as it adds more punch. bridged at 2 ohm. with a one farid capasitor. running on a planet audio 2 ohm stable amp at around 300 rms. i am super impressed, i love jl audio but i also love my money. im going to buy a couple more to put in the closet, cuz my freands are going to want some too. but im gunna charg them $75!! ha ha!

i have four of these speakers on a rockford t10001bd and they hit pretty hard not very good on low end bass but they say u get what u pay for and thats the truth when it comes to these speakers but for the price u cant go wrong overall a decent sub

Well worth the money. Have 2 in my Ford Ranger XLT, wired at 4ohm bridged into a Kenwood KAC-8105D and it is VERY, VERY, VERY loud. Have one in the trunk of my GF's Dodge Stratus with a JL Audio 250/1 wired to 2ohm and its nearly as loud as my truck!!! WELL WORTH THE MONEY!!! HIFONICS IS A COMPETITOR!!!

i have four of these in a bandpass box on a 2000 watt hifonics brutus and they hit hela hard they cant get low in the box but they have broke three screws that hold the plexiglass in

i have 2 of these HFI12D4 monsters hooked up to a "planet audio 1000.2" bridged @4ohm (700rms)...so 350rms to each, in my grand cherokee...unbelivable.. I thought id blow them but they handle it perfect.... Ive had some top name brands and these are awsome for $30 subs.... I was on a budget and wanted to replace my JLw3's i had...SO I READ THESE REVIEWS AND TOOK MY CHANCE....SO GLAD I DID...the only 12's ive heard sound as good as these were my JL's ,and orion XTR, ....and they all cost me over $125 a peice at the time.... I call them monsters because the bass is crazy loud..shook my fog lamps loose (so they pointed down)on my front bumper and makes my wiper bounce off my rear window with just 2 of them .. cant go wrong with these... Im about to upgrade to 4 of them and a "planet audio ac2000.2"...(700rms X 2)....2 more subs and amp will cost me $180....so for $300 i got one hell of a system that will blow away most $2000 systems...lovin it.....but since im not 17 anymore... I dont need 4-12's, 2-15's, and 2-10's to be cool anymore......but you be heard from half a mile away,set off car alarms, and.. WILL GET A NOISE POLUTION TICKET WITH THESE SUBS.....ha ha....PLAY AT YOUR OWN RISK

not too bad for 50 bucks a pop. it only has holes in the terminal for 16 ga. wire that kinda sucks. running 2 off a memphis pr1.500 wired to 1 ohm and they do work, not too good on the lows. i got these to replace the 2008 boss audio diablo 12s i had and they hit way harder than these do. not too bad tho

i had written a previous revew for this speaker, but now i realize it's not as good as i had previously thought. still a great starter speaker. and it hits hard right out of the box, but it wont last, if pushed to it's rms watt on a reguler basis, expect to clip the voice coils in a couple months, i drive a tuner car and dont want 400 lbs of stereo in the trunk, so i generaly buy one sub and push it at it's limit, this sub only handled about 350 clean watts for a couple months. now thair trash. but if your not worried about weight two in a big box @ 400-500 watts rms would make for a clean reliable system at a great price.

Running one of these with a crunch pzt1400.2 bridged at 8 ohms hits hard soon the be getting two so i can bridge it at 4 ohms 1200 watts

Well i will start off for the sound these things beat good, but i will say at certian hertz the plastic back will rattle but at low hertz it doesn't. I put 300-325 into it for about 45 at loud volume (the only way i listen) and it smoked don't really know if i got a bad speaker or just too much power. But we will see im sending it back and will write another review when i get mine back. Oh and the terminal holes are kinda small for sub gauge wire... Just FYI

I replaced my Soundstream sub with this Hifonics model and ran it at 8 ohms with 240rms on Tap. The box is 1.8 cu ft tuned to 40hz, a bit bigger then the recommended 1.6 cu ft but the tuning port is same. The subwoofer seems to be very good performing sub, but I have noticed at certain frequencies the plastic covering seems to rattle and the sound was eminating from the port. This is usually at high volumes and with a lot of cone movement. Will see if I can take the plastic casing out from the back. The sub has good excursion limit and the only drawback is the rattling. For an entry level sub, the manufacturers have spent money on its mechanical factors and it matters the most. Just follow the manufacturers recommendation with box requirements and I am happy with the result. A great buy for an entry level sub that performs very well. Another downside is the effecieny of 87db /1mtr, you will need a good amp to drive it. Highly recommended as an entry level subwoofer!!!

Ive got an ssl 5000 watt class d monoblock running two hiphonic dvc the amp has blowed alpine type r 12 and sony 10,12 when u drop the ohms1 ohm its really pushes the watts il let yall no in a few days if the subs realy as good as everyone says so for they are taking it but i also dont have my amp jacked up but about half so far there taking it i think if they will handle it il get two more just for the bang bc i thrive on it its my passion to feel my whole truck vibrating ridiculous im a strate bass head junky. I have been spendinging one speaker what i could probally buy like five of these for one of them if anyone wants a badass amp ssl 5000 cost me like 180 with warrenty for two years and its probally the best amp ive ever had its about a year old now so far never had an issue with it im hopeing that i can say the same about the subs 94silveraldo ext cab is very impressive they fit under the back seat of course i had to build my own box face them down to the floor board stay up about an inch for movement and still have all your room with two
