  • Bets budget subs i've looked at
I have been looking for subs for my girlfriends car and she didn't want anything to expensive. The Amp can defiantly throw enough power to these subs and its a little underrated as tradition for MTX audio. I have the gain all the way up at the moment and have been pushing them for about a day, the only reason the gain is at its max is because the stock head unit does not push out that much low end audio which is whatever. The subs defiantly sound great, they don't hit the chest hard because its a sealed box but the frequency response is great as tradition for a sealed box, I did put the actual units themselves into a ported box and they hit hard so if that's what your looking for is that hard chest punch, defiantly look at porting. All in all so far so good, they punch good for the money and I'm happy with them. P.S. maybe get new wire running to the speaker, the speaker wire seemed kind of flimsy so I went and got some 12guage which defiantly seems a lot better. ... show more

  • Worth it!!!
I was terrified to give these a try. The price for this scared me into thinking it wouldn't be great quality or that they would blow in a few days. It seemed too good to be true.. but let me tell you!! It was worth the risk, and I LOVE my subs. I had terrible stock audio with blown speakers in all 4 doors and I was in need of an upgrade immediately. I used everything they gave me (the 8 gauge wires, amp, and subs in the box) and I had it professionally installed along with a new aftermarket radio. I've had these a few months and I'm very pleased with the sound and performance from these subs. Best $300 I've ever spent. Everyone loves the sound and all my friends ask where I got them. No one can believe these are $300 subs from Amazon. All I can say is, just do it.. buy them, you won't be disappointed! ... show more

  • Bigger amp is needed other then tht they bang pretty good.
Sound system for my truck. The amp wasn't big enough to REALLY put out the bass it can.
Reviewed in the United States on September 22, 2024 by The subs sound great and bang but the amp tht came with them just isn't powerful enough to push them like they are supposed to. Other then tht great!!

  • Not too shabby!
My first impressions as any other persons was the price of the product I really looked into it on YouTube did my research and seen a couple videos and tutorials on peoples systems in their own car it was still hard to determine how good the quality was because they were recording it and it was uploaded in poor quality or the microphone just wasn’t working right.. So I purchased these at $273 for my 1995 Toyota Corolla honestly these were worth the buy. The set up was very easy to install. I seen comments about the speaker wires being cheap or thin but in my case they were that bad. Not the best but still good quality! When the product arrived the Speaker wires and the subs came is to separate boxes so be aware of that. The box for the wires is small but the subs of course are huge so sometimes you might have that delivery driver that might not have been paying attention that day and that’s maybe why you didn’t received the wires with the subs in the box. Overall these were a great deal! Everything was included like what more could you ask for at no more then 300$!! Great Job MTX! ... show more

  • Sounds amazing!
Had some trouble finding an accessory wire to tap into on my Ford Fusion, but after figuring it out and trying them out for a while I am very impressed! Kit came with everything needed and again it sounds awesome!!! Edit: Amp blew up about a month and a half later, I noticed it was overheating for a while and one day it shut off in the middle of a song. Get a better amp for these subs, that’s my only recommendation since they do sound nice compared to the stock system of my ford fusion. ... show more

  • Nice setup for the money.
Looks good in my new Tesla! Sounds good too. Amp was fried ootb but spreetail instantly without hesitation or question prepared me a return label (at midnight on a thursday) and had sent me a new one with a 5 day turnaround. Therefore I went with a different amp during the install and can't tell ya about the amp but from what I hear the 400watt rms is under rated. Speaker I bought was the mtx dual 12 wired in series at 2ohm. Sounds nice so far and will sound better once it's broke in. Sound investment. Really happy with the Spreetail customer service. It's old school an a very nice feeling when a company is that dedicated to happy customers. ... show more

  • Horrible customer service... faulty product!
So I bought this a couple months back. I just got around to installing it. It won’t work. I have power, changed out ground. Have Remote in. And it just won’t produce sound. I emailed seller for help. He originally offered to help. I responded with a thank you and then this morning he comes back and says it is outside the return window and can’t help. They didn’t even offer any other help, like a tech support number. So I took my car over to a local car audio shop and they said the amp is faulty. So here I am. I suggest not buying this produce or anything from this seller. If you do... install within return window. ... show more
