The Terminator653's 3-way design offers a cleaner transition from the midrange to the high frequencies.

It's time to upgrade                            

MTX is looking out for you. They designed the Terminator Series speakers to put out serious sound without you having to empty your bank account. If you've been dying to replace your burned-out factory speakers, but haven't been able to justify the expense, MTX takes guilt out of the equation. And with protection under MTX's unique 5-year warranty, this buy is as practical as it is fun.

What a speaker

These Terminator653 6-1/2" 3-way speakers will take your in-car audio experience to the next level. The durable polypropylene woofer and Mylar dome tweeters are vast improvements over the standard paper cones used by factory speakers. With the sensitivity of these new materials, you'll gain more focus in the midrange and clearer highs, even from the power of a factory stereo. But if you have an aftermarket stereo or amp, you can listen with confidence since these puppies can handle up to 45 watts RMS. Grilles are included for custom installation.


  • 6-1/2" 3-way car speakers (pair)
  • polypropylene woofer cone
  • Mylar dome tweeter and supertweeter
  • frequency response: 54-20,000 Hz
  • sensitivity: 89 dB
  • RMS power: 2-45 watts (90 watts peak)
  • top-mount depth: 2"
  • grilles included
  • warranty: 5 years (free repair or replacement for 2 years; prorated replacement for years 3 through 5)
  • Our 60-day money-back guarantee

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Crutchfield Customer Review (What's this?)

I installed these speakers in my 2001 GMC Sierra and so far I am very pleased with the way they sound.

Pros: Nice clear sound and good bass.

Cons: The installation hardware included with the speakers didn't workout well. I did use the mounting screw and purchased rubber washers.

Crutchfield Customer Review (What's this?)

I purchased a set for the front doors. I didn't notice a big difference in sound from what I already have. Buying the speakers with Crutchfield was great, I recieved the wiring, brackets, and installation instructions. Super fast shipping. I will be installing an amp and subwoofer soon for better sound.

Pros: Clear sound

Cons: Didn't notice improvement from the oe speakers

Cons: none

2003 Nissan Frontier

Written By 808 surf, Kailua, HI on Wednesday, June 24, 2015

Crutchfield Customer Review (What's this?)

Sounds good after break in period. When first installed in doors, had no bass. After 1 day of breaking in speakers, bass response improved. Speakers fit under stock door panel speaker grills, no need to use MTX grills provided. Needed to use speaker adapters provided free from Crutchfield. Slight modifications needed on speaker adapters. Had to enlarge speaker adapter holes that mount to door panel. Big improvement over factory speakers.

Pros: -high response good -power output good with stock stereo, no external amp

Cons: -low response fair -speaker adapter modifications needed

Crutchfield Customer Review (What's this?)

Sounds way better than the old original equipment that was in there. Fit right into original mounting holes on 98 GMC Savanna. The wiring kit that came free with it made the wiring a no-brainer & was the best part of the install (other than driving around & listening to superior sound).

Pros: Free wiring kit was even polarity matched to the speakers.

Cons: None

Outstanding Quality Sound

Written By Greg, Florida on Thursday, May 14, 2015

Crutchfield Customer Review (What's this?)

I installed the MTX Terminator653s to replace the stock speakers in my 11' Chevy Silverado. The speakers sound great and added a little more bass; however, I will be adding a powered sub real soon to complete the sound a little better. The install went very smooth due to the user friendly install kit and instructions.

Pros: Crisp clean sound from mid to high level volume, added a little bass.

Cons: Your going to still need to install a sub to get that premium sound if that's what you are going for.

2008 GMC Envoy

Written By Justin in Vermont, Vermont on Wednesday, April 08, 2015

Crutchfield Customer Review (What's this?)

Just bought a used 08" Envoy. 3 of the four factory speakers were blown. I bought a pair of these for the front doors and a pair of Polk DXI651S for the rear doors. The MTX is clearly the better sounding speaker in my vehicle. That is not to say the Polk isn't a fine speaker, it's just that with my stock stereo...the MTX's sound a whole lot better.

Pros: Rich sound with nice clean base, reasonable price and Crutchfield sent me the little parts (wires) I needed to do the install. What a nice repair for this vehicle.

Cons: Not made in the USA? Well maybe they are? I'm not really sure. I like everything else about them so that would be the only con.

Crutchfield Customer Review (What's this?)

I bought an aftermarket cd/mp3 deck for my girlfriend's 2005 Trailblazer last Christmas to replace her crappy stock stereo and when the tech installed it, he informed us that all of her speakers were blown except for the driver's side and even that one was on its last leg. So, I remembered Crutchfield from purchasing an amp the previous year before and found these awesome, kick-butt MTX 6 1/2 speakers for a decent price. I installed them along with two 6 1/2 kenwoods and the sound was Awesomely Unbelievable! My gf is happy; therefore, I am happy. Crutchfield is the best site to purchase aftermarket audio and I will definitely continue to use them in the future for all other audio purchases.

Pros: Sends everything you need for the install Great price Huge selection Fast shipping and delivery Outstanding customer service

Cons: NONE

For 2007 Civic Hybrid

Written By Adam, Utah on Monday, February 16, 2015

Crutchfield Customer Review (What's this?)

Purchased these on scratch and dent sale for my 2007 Civic Hybrid. Replaced the factory rear speakers. These sound excellent. Easy to install with Crutchfield's installation support (wiring harness and speaker adapter). Definitely would recommend.

Pros: Great sound, easy installation.

Cons: None

Crutchfield Customer Review (What's this?)

The speakers were a snap to install. The sound was very much an improvement over the old, factory installed units (3 of the 4 had died). I expect these to last the life of the truck.

Pros: installation

Cons: none

Installed these in my Accord with a factory HU and no amp and it sounds 10x better than factory. I am very pleased with the purchase of these speakers.

Pros: Sounds excellent

Cons: Hardly any bass but that was expected.

More than I expected. :D

Written By Kevin, Minneapolis, MN on Friday, January 23, 2015

Crutchfield Customer Review (What's this?)

I was pleasantly surprised by the quality and range of sound from these speakers. Way more than I expected. I'm using these with a kenwood 50w x 4 deck mainly for the mids and highs and it fills my car with sound. I only bought 2 for my front doors but after hearing them, in definitely going to buy another pair for the rear doors.

Pros: -crisp/clear mids and highs -mounted very easily -sounds good at all volumes as long as the low frequencies are limited

Cons: The only con I've found is they can't handle too much low end at higher volumes. But if these are accompanied with a sub there's no need to run the low frequencies through them.

Tighter than stock

Written By BilllT, Canby,OR on Sunday, January 04, 2015

Crutchfield Customer Review (What's this?)

Much better bass response than stock for a cleaner overall sound. Very pleased with sound. only problem with installation was with mounting speaker to adapter plate, outside diameter of adapter mounting surface just came to inner diameter of the speaker mounting holes, so had to drill inward angle thru the sidewall of mount to get screws in. For this reason I gave 4 stars instead of 5.

Pros: Tight bass and smooth all the way up to highs

Cons: Install adapter not quite large enough for MTX mount, had to hotglue and angle speaker screws into the side.

Good speakers for the price. Replaced the stock speakers in my 2014 Nissan. Worked good with the stock stereo. But sounded even better with aftermarket stereo.

MTX Terminator653

Written By Jerry, Wisconsin on Wednesday, December 17, 2014

Crutchfield Customer Review (What's this?)

These are some really nice speakers for the front doors. 45 watts each, and the sensitivity level is 89db, a perfect match for the alpine under the dash amp. I've listened to a variety of speakers, and I still like MTX even though I was subjective while listening to other well known brands. But I would also like to point out that there is a difference in the Terminator and Thunders. The thunders are more heavy bass driven, and have a higher sensitivity level, but depending on the vehicle, and the space, one may be a better choice over the other. Of all the full range speakers I have put my ears to I still believe the MTX has more of an accurate bass sound. If the bass is off the mid, and highs will not be appreciated as much regardless of how accurate.

Pros: Clean balanced speaker the bass doesn't overwhelm. MTX's redesign of this particular speaker produces bass sounds even better.

Cons: None.

So far, so good...

Written By jw64wpb, Florida on Monday, December 08, 2014

Crutchfield Customer Review (What's this?)

I bought these at the advice of my Crutchfield adviser Bob. I like the overall construction and I wanted something comparable to Polk audio which I am partial to. The sound is good, but I won't know the true quality until I purchase an amp to make them run more efficiently.

Pros: Good construction

Cons: smaller than I wanted since the front door stock is a 6x9

MTX Terminator 6.5 speakers

Crutchfield Customer Review (What's this?)

These speakers offer a tremendous value. The rear speakers in my Lexus IS300 were blown and I was looking for a high quality replacement that wouldnt break the bank. I got that in spades with these speakers. Highly recomended.

Pros: crisp sound, great price, very easy to install with all the parts provided by Crutchfield. I would never buy stereo gear from anyone else.

Cons: none

Great sound.

Excellent Sound / Budget Friendly

Written By Robert, Nassau Bay, Texas on Monday, October 06, 2014

Crutchfield Customer Review (What's this?)

MTX hit it out of the park with these speakers. These 3-way speakers were perfect for my install. I have a Pioneer BT Receiver with 50watts x 4, and I needed speakers within that range that didn't require a lot of power. These were perfect. The sound quality is excellent and sound great throughout the whole sound spectrum. They fit perfectly in my doors as Crutchfield said they would.

Pros: Budget friendly, low wattage requirement. great sound.

better than stock. good price.

Written By Ace, Honolulu on Sunday, September 14, 2014

Crutchfield Customer Review (What's this?)

Nice step up from stock speakers. Acceptable price, fits speaker locations, easy installation. I install these in all four doors of 2012 Sonic hatchback. Still have stock receiver because of other Sync stuff, I made no adjustments to settings, just running stock. After replacing, MTX 653 were noticeably better than stock, fuller range of sound. When turning volume to prior self-determined max volume (or deal with stock distortion), MTX 653 produced crisp highs and midrange, no distortion of lows.

Pros: new 3-ways versus old stocks just sounds better, fuller range of sound. fits location as stated, 6 3/4" or 6 1/2". For the market level MTX 653 goes for, good price for entry level 3-way speakers.

Cons: installation kit fit nice into doors but screws and securing speakers to bracket kit should be better; not much plastic for screws to bite into.

Great sound for a great price!

Crutchfield Customer Review (What's this?)

Great speakers with great sound at a great value. I installed these in the front doors of my wifes 2006 Trailblazer. She already has an aftermarket stereo so these speakers just finished that off and she is happy happy happy! The installation was easy so that made me happy happy happy. I paired with the MTX TDX65 two ways in rear doors and that's it, done deal. Open and shut case, time to rock!

Pros: Great sound, especially at higher levels. Above average at low level, where you would have it when talking to others in car, but excellent at higher level. Crystal clear highs, no bass distortion. Easy install, easy instructions, no wiring. Plug & play all the way!

Cons: Haven't found any yet

Product Research


Woofer Cones: The MTX Terminator series speakers feature durable and rigid polypropylene woofer cones. Polypropylene is also resistant to the moisture and temperature extremes found in automotive applications.

Tweeters: Each speaker has a Mylar dome tweeter and super tweeter for clean, accurate highs.

Speaker Size: These speakers are marketed as 6-1/2"; they will fit in standard 6-1/2" speaker openings, but do not use the industry standard 6-1/2" speaker bolt pattern (then again, neither do many car manufacturers). In order to install them in standard 6-1/2" speaker openings, one option is to drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes and the Ford non-symmetric four hole pattern. When using the brackets the depth becomes 1.823" and the mounting height becomes 0.894". The speakers will also fit many factory 6-3/4" applications. Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

Specification Note: MTX seems to list contradicting power specifications on the box; with the other specifications they list 90 watts peak, but on the front of the box they list 135 watts max power. We've adopted the 90 watt rating simply because it's the more conservative figure.

Warranty: MTX offers a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.
