Great speakers. Using an amp with mine. Tweeter is a custom install. I used a 2" hole saw and CAREFULLY (slow) made holes in my upper pillar trim, then finished my cuts by hand. Woofers (6x8) did not match up to the factory hole locations. Only two of the four holes lined up. Very disappointed with MTX, but luckily this is an easy fix using a sharpie to mark the hole and a 1/8" drill bit. Run all new wires through factory locations in the door using a flexible grip tool (Harbor Freight had cheap ones). Driver side is tough! Plastic piece in the way near the park brake. Passenger side - simply lower glove box out of the way.

Pros: Sound

Cons: Lengthy install. Tough what to get to if you're rewiring. Which I recommend

Sorry to say I had a very hard time trying to make these 6x8 go into my Ford F-150 that has 6x8 that came out of them they didn't line up like I thought they would it was a problem at first but I figured out a different way hoping that they will work and hold in the spot that they belong in I have to say where the four screws go in to melt into the doors are not the same size as the new 6x8s that I installed the old 6x8s are probably heavy eighth of an inch smaller than the new 6x8s Thunder 681 that I installed but overall I did get a man it should have been 5 minute job to swap out one speaker it took me 15 minutes to swap out one because of the holes don't line up with the new 6x8 Thunder 681 but now I have finished installing all four and two new tweeters and now I'm figuring out where the hookup the other tweeters in the back then I will work on what kind of if I can install with maybe under the seat woofer with the built-in amplifier

Customer Service was excellent. Sage hooked me up with these component speakers for my 2009 Ford F-350 crew cab. My health has prevented me from driving for the past 12 years. I wanted the best equipment within my budget for listening to 80's Rock and Country. Sage was spot on and she reminded me of the needed accessories to make my dream come true.

Pros: Great service Fast shipping Quality

Cons: None

Smokin' price on not-that-common 6x8" components

I've had these in my '03 Mustang convertible for a few years ago, just in the front. I have a Rockford Fosgate P4004 50wx4 amp powering them. They sound darn good. I just got a new (refurbished) Kenwood deck at a smokin' price here, and these MTX's sound even better now. I previously had the old JVC Bongiovi deck that Crutchfield cleared out several years ago. I had that with a Clarion 7-band old-school EQ. With that weird setup, these MTX's were a little brash in the mid-range/treble department. I had my 2.2khz dial turned all the way down most the time. They sounded darn good overall, but like I say, they were a little bright, which I realize is also a function of my amp gain setting and fader setting, etc. That EQ has what, a line driver in it basically too so again, I once described the sound as potentially "blistering" to my install guys. But yeah, now with the Kenwood DPX792, they sound more normal, more crisp, and not so overdriven. It looks like 6x8's with separate tweeters (components) aren't super common, so I'm glad to have these. My Mustang had the "Mach" system so the tweeters are up on the corner of the door/window; it's a cool setup. It'd be a shame to just stick 2- or 3-way 6x8's down below in the door spot and not do the separate tweeter up top. Gotta go with components.

Pros: Sound terrific, separate components in 6x8" which you won't find everywhere, great value, takes a slammin' but keeps on jammin'

Cons: None come to mind, and not just because it's hard to think when I'm crankin' my jams to high heaven
