Pretty good sound for he money!
Style: Dual 12" Subwoofer Enclosure + Amplifier...
My son was saving up for a system for his car and like me, he likes good clean bass but doesn't want to go deaf or rattle the neighbors pictures off the wall. We set this up in his car and I was pleasantly surprised they were louder than expected and had a great clean bass line. Something seemed a little off. Like they could actually be louder. I quickly learned his receiver differed from mine. I have way more settings and his didn't have a lot of options. So we bought a new receiver like the one in my truck. It hit a lot harder with the right setting at the receiver. I was impressed with the quality of the speakers, the box construction, the carpet the stitching of the brand name. The amp looks a little wimpy but it has done the job. We haven't really stressed them nor had them very long so I cant say how long they will last. They seem well made so im not rally worried. The packaging from the factory is awesome. I suspect these speakers will last a good while as my son knows the difference between good sound and distortion and understand the consequences of trying to play something at full volume. We found the sweet spot at audio level 52 (the receiver goes to 62.) Paired with Rockford fosgate door and rear deck speakers and factory tweeters. It sounds amazing! Keep in mind you aren't gonna win any audio competitions but you will have great sound and a little thump you can feel in your chest. ... show more

So loud
Style: Dual 12" Subwoofer Enclosure + Amplifier...
This sub sounds amazing. It was easy to setup with the amp and it is extremely powerful. It is pretty big so make sure you have enough trunk space if you plan on still using the trunk with the subwoofer in it.

Best bang for the buck.
Style: Dual 12" Subwoofer Enclosure + Amplifier...
For the money, I don't think you could beat this deal. The amp puts out an honest 400 watts @ 2 ohms with no clipping. Tested @ 40 Hz with a Fluke 87 and an SMD DD1 using the speaker as the load = 28.9 volts into a 2 ohm load. I stuffed the box with 3 lbs of pollyfill, inverted the right woofer, removed the plastic / rubber trim ring and flipped it over, reinstalled it and wired it electrically out of phase. I will clean up the wiring and remove it from under / in between the speaker and the box later. I did that for testing purposes only. Acoustically in phase for a push/pull configuration. Not to be confused with compound or Isobaric. I am really impressed with how smooth the response of this box is. It is very musical and still hits pretty hard for 2 twelves. All and all, the construction of the box is descent. The spring-loaded terminals are descent and the 12 awg wire that is inside the box is soldered to the terminals and to the speakers from the factory. The Kicker GR120 12-Inch Speaker Grille fits like it was made for it. Even the locating pins on the grill fit right in the screw holes on the speaker. The screws that hold the speaker in the box are long enough to hold the grill to the speaker / box and are not tapered. ... show more

terminator subwoofers
Style: Dual 12" Subwoofer Enclosure + Amplifier...
All I can say about this product is that it is well worth the $200 i spent. MTX makes some very good sub woofers and for the price, you can't go wrong. It is very well made and very well packaged. The kit includes the dual sub woofers, and a 250 watt amp. I have these babies set up in my room because the power and the quality of car stereo speakers in my opinion are better than any home theater sub around. Ive owned these for about 3 or 4 months now and they still sound great. The only complaint I have about these subs is that they wont sound good if I increase the volume on my stereo receiver past 50% of the max volume. After that point, there is a significant amount of distortion that makes my music sound like crap, but it might have something to do with the stereo receiver I'm currently using (It's an old school stereo receiver from soundesign. There are videos on youtube about people who have these subs shaking the whole car, and for some reason, mine aren't that powerful. very good buy. ... show more

Damn good
Style: Dual 12" Subwoofer Enclosure + Amplifier...
I bought this as my first system ever this past summer, knowing little to nothing about car audio. After buying a wiring kit and all of the other neccesary installments, I hooked this up in my accord. The good: -Easy to install, i used 8 gauge wiring, and followed the directions i found online on how to hook up basic/amps subs. -Monoblock amp, 1 channel. You'd have to be an idiot to hook it up wrong, as there is ONE positive, ONE negative speaker terminal....and with the subs being 2ohms, all you need is a +/- speaker wire each, and thats it. -Hit moderately hard. Had them in the trunk, which was most effective bass sound. These subs dont push too much power....they probably hit like 300rms....but they hit the mids-mid/lows pretty good. Very satisfied. -Overall high quality design. subs and box made of very nice material. Now the bad... - Amp gets hotter than hell in the summer, and under heavy use. Its monoblock, so yeah, i was expecting it to get hot, but i could have probably cracked and friend an egg on this at some points. Sends itself into protection mode pretty often in the summer (i live in ohio....around 85 degree days...) - Not too powerful. They are really good for a first system, but after awhile, you will realize there is bigger and better out there overall, very good setup though. ... show more

Great for a first time dabble into car audio
Style: Dual 12" Subwoofer Enclosure + Amplifier...
Purchased this product a little over a year ago, they still work great and provide a nice crisp and sharp bass. If you are looking to get started in car audio and don't really want to learn about the technical stuff then this is probably gonna be for you. While it is not easy to install as it does not come with the wiring kit, and you will still have to know what head unit and car your trying to install this on I would say that it is worth the time and effort to install this. If you are an experienced car audio enthusiast, then why are you reading this review? There are far better options for more money. Conclusion: Great value for the first timer! Installed my head unit and these subs on a 1985 Honda Civic Hatchback over a year ago and they still work just fine in the heat and in the cold. ... show more

These are amazing!... when they work.
Style: Dual 12" Subwoofer Enclosure + Amplifier...
If you're buying these for the price, I highly recommend investing in a new amp. The subs sound fantastic if you have a nice head unit and after market speakers. I purchased a double din Kenwood DDX-719 as long as 4 Pioneer TS-G1643R's. My wiring is pristine, I did everything myself. I soldered all of the connections. The subs sound amazing. You have to spend some time tweaking the sound settings on the receiver and the amp but once you get it to your liking they sound great! HOWEVER.... they hardly work! Yea I may listen to my music louder than most people and I do go on extended road trips all the time. But that is NO excuse. If you're going to package an amplifier with a pair of 12" subwoofers make sure they are compatible! The subs are hardly getting ample amount of power from the amp. A lot of it may be from the incredibley hot, humid, temperature. I was on a road trip from Texas to Illinois (and back) and all of a sudden my subs gave out. I pulled over, popped the trunk and the power light was off. When I touched the top of the amp, HOLY HECK was that hot. So I turned the volume down and continued driving. The subs will come back on once the amp cools down enough. I started having to drive around with my back seat down so it could get enough air circulation. Happens just about every trip over a half hour. If you go with this item MAKE SURE YOU IMMEDIATELY REPLACE THE AMP! ... show more
