MTX Subs

Written By Bob, Wyoming on Monday, October 05, 2015

Crutchfield Customer Review (What's this?)

I installed the MTX subwoofer package in my daughters truck and the installation was a snap. It look really good and sounds decent for for the price. The only issue is the subwoofer volume control does not work. I'm still troubleshooting the issue and sure it is something very simple that I am forgetting.

Pros: Good price, well built and very easy yo install.

Cons: Amp should have more power to push two 12's.

Save your money for a better setup

Crutchfield Customer Review (What's this?)

I should have listened to the bad reviews. You get what you pay for. Was optimist, hoping for mediocre performance for my commuter car. I would have been happy with that for the price. The amp is garbage. Has no power and overheats in 5 min. Installed it on a Friday night and my first drive to work on Monday morning just did not have much punch which was disappointing. My single Phoenix Gold 12 in my truck and single Kicker 12 in my vette just murders the 2 MTX's. On the way home the amp shut off 5 minutes after I left. Pulled over and found it shut down due to over heating. It came back on after 15 minutes then cut off again after a few minutes. Did this 4 times and I just turned off the music because I was so aggravated. I would return the whole system but not going to pay to ship it back. I will put that money towards a new amp. I think the subs will perform OK with adequate power. Anything is better than them not playing because of a poor quality amp shutting off. Never had this issue with Kicker, Phoenix Gold or Rockford. Now I will have more money invested than if I bought better stuff to begin with. Shame on me for trying to save a dollar. Reviews are the same on the MTX website also. Sorry MTX but had not bought your products in over 20 years and will not be buying any again. Kicker all the way.

Pros: Subs and box are OK for entry level components and will probably perform reasonably well with proper power.

Cons: Cheapest amp ever. No power and overheats in 5 minutes. MTX needs to quit selling this amp. Ends up being a more expensive deal once you purchase a good amp.

Crutchfield Customer Review (What's this?)

assuming you mount everything well you wont have a problem with the amp overheating, all the reviews talk about it overheating or being to small of an amp but this is a very well matched combination sounds great very loud and looks good too. great combo for the price

Pros: Loud, clear, tight bass, everything is paired well

Cons: It does ship from a separate supplier then Crutchfield so make sure you are prepared to wait just a couple more days if you order a deck with this

These subs hit super hard, and clean! Great for the price. When I first installed them, and was tuning my amp my neighborsccame out, and yelled at me. Haha. All my friends compliment my sound system, and ask me where I got them. They go great with my Pioneer speakers, and Sony head unit.

Pros: Subs are amazing.

Cons: Amp is small, but great for price.

Great beginner package. Easily installs

Pros: Matched components

Cons: Doesn't come with any instructions or info on the amp or speakers

Amp is too small

Written By cookmar, Orange Park, FL on Sunday, March 23, 2014

Crutchfield Customer Review (What's this?)

The speakers are nice, however they can handle much more than what the amp is supplying. Also, the amp is getting really hot and that worries me. This set should be paired with a larger amp in my opinion.

Pros: Speakers and box are nice.

Cons: The amp gets hot.

Great subs

Written By Mr. Main, Greenville NC on Thursday, January 23, 2014

Great subs. hit 129 db with them in my 2010 ford focus. The amp did burn up though. I have a 500 watt alpine v power on them now and they shake the windows in my house from the yard. Great subs. decent amp. Very very loud system for people on a budget.

Pros: loud and clear for the price.

Cons: Bad amp

Quality combination

Written By Bo, Brandenburg, KY 40108 on Monday, December 30, 2013

I drive an 01 Cadillac DTS and 2 different stereo installation shops told me I'd have to get a different car to get a good sounding system. I bought these and people have told me they can hear me coming over a block away. Great addition to my factory Bose system.

Pros: Clean crisp sound. Clear bass.

Cons: Only complaint I have is amp overheats too often.

It is the perfect amount of bass for my vehicle. I love the look and sound of my subs. Easy hook up and a Perfectly sealed box.

Great Subs, weak amp!

Written By Dave C, Currituck, NC on Tuesday, July 23, 2013

Crutchfield Customer Review (What's this?)

I gave it four stars because the subs are great and they hit hard but the amp's gain has to been turned up high for them to hit but the amp over heats.

Pros: Great subs

Cons: Weak amp, over heats

These sube are the best i've seen at my school.I've been in two cometitions in school parking lot and got 2nd both times ( would've gotn first but people ith the MTX thuder beat me). Best thing you can get your son for his birthday or make him save it up and buy it like i did.

Pros: Price is amazing and vibrates the car

Cons: When you install the amp and it has 3 blinking lights then make sure you chek all the wires and ac adapters... And be sure to turn off your car for one minute in between fixing somthing or it want change anything

I love it! They hit so hard and they were cheep!

Not bad, just the little things that are disappointing

Written By Jay, New York on Wednesday, July 17, 2013

Hooks up pretty easily, sounds good matched with my old Jensen DVD unit. Really adds a new dynamic for the low hit bass that had been missing from the sound profile. Picture above shows it having two terminals on the rear which I was hoping I could use with a Sony xplod 2/4 channel amp however it only has one spring clip terminal when it comes out of the box. No big deal, why I went for the amp package as well but was somewhat disappointed that the picture didn't match up. One of the screws was missing from the amp, small one that holds the remote wire, nothing a trip to the hardware store didn't fix however.

Pros: Sounds good, decent price, straightforward hookup

Cons: No documentation at all in the box and the amp doesn't show up on the MTX web page. Still haven't found a comprehensive manual online. Picture shows two terminals on the rear of the box but it only has one.

Crutchfield response on Thursday, August 01, 2013 Thanks for your review. We have removed the picture with two terminals, and we will be updating with a corrected picture of this item.

Crutchfield Customer Review (What's this?)

It shipped from the manufacturer, and I got it in 4 days. Just got this hooked up by a performance shop here in town. This thing is paired very well, and it really thumps! It comes with a remote level adjustment, which is a good thing. For different types of music, you can tune the amount of bass that is appropriate. But when you want it, these subs and amp will get busy! Very satisfied, and a great price.

Pros: Quick delivery, very loud, thumping bass.

Cons: Only thing I didn't like was that it didn't come with an owners manual. Should have had instructions on proper installation, tuning, remote control setup.

hits hard....amp sucks

Overall it hits hard but the amp constanlty over heats and turns off

Pros: Hits hard

Cons: Shuts off every 20 mins


Written By D L, Maryland on Monday, July 08, 2013

Crutchfield Customer Review (What's this?)

I only gave this combo 3 stars because the amp is sooooooo WEAK. It sends out good bass but has to have the GAIN turned way to far down in order to prevent it from over heating and shutting off. Once its turned down to the point it doesnt over heat, you cant even hear the subs. I have to ride with my rear seats open so that I can let air from my windows being down keep the amp cool. Sometimes that doesnt work because its so hot outside. I am either going to build a fan unit for the amp or im going to purchase a new amp. The Subs are extremely nice. They have some serious bang to em. I would not recommend this COMBO to anyone but would definitely recommend the subs,

Pros: Awesome SUBS!!

Cons: Amp overheats and requires a really low gain setting to prevent over heating.

This Sucker Thumps!

Crutchfield Customer Review (What's this?)

Really, really great package. Very attractive black carpet subwoofer enclosure, expertly crafted and solid 12 inch subs, amp gives off great power resulting in thunderous bass response. I have to actually turn the bass down more than half-way!! Very powerful! A nice, unexpected surprise was the cute little external bass control (EBC) potentiometer- which is now mounted nicely under my pull-out ashtray!! Overall, a super product that exceeded my expectations by miles!! I highly recommend.

Pros: High-quality, attractive appearance, well-built, very powerful, great value

Cons: None

for the money- AMAZING

Crutchfield Customer Review (What's this?)

You really cannot beat this package for the price. I installed them in my Explorer and they sound great. Amp and box are made for each other. Purchase a wiring kit and hook it all up. The lows are amazing and it only took a week for it to come in the mail.

Pros: Deep low bass. Easy to install. Fast shipping.

Cons: I feel like another 100 watts would do this package justice.


Written By AL, NJ on Saturday, April 13, 2013

Hey guys, if you're looking to buy this package deal. DO IT! First subs ever and let me tell you, the bass these things produce is amazing! If these are your first subs get them great in every way. Even if they aren't your first these will rock your world and car. Even with this little amp they sound amazing. I can't wait to upgrade the amp and see what these do at full power!

Pros: Great sound! Great price! Awesome tech help!

Cons: Amp gets a little hot but nothing you can't fix with the windows open. Ships from manufacturer so expect 5-7 days shipping. Was a little mad when I found out about that.
