About the MTX Amplified ThunderForms
Crinkled french fries, discarded receipts, old gum wrappers — you probably have everything in the hidden corners of your vehicle except great bass. But with custom ThunderForm enclosures, you can fill the nooks and crannies of your car, truck, or SUV with low tones that stand out.
MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. With "rotational molding," MTX ensures that each ThunderForm fits and blends inconspicuously into your vehicle. They're made of high-density polyethylene resin to curb resonances and deliver bass that's tight, hard-hitting, and way down low.
This molded MTX ThunderForm comes loaded with two premium-quality 10" Terminator subwoofers modified especially for amplified Thunderforms, with a specially-designed amp that puts out 200 watts of power. It installs in your 2002-up Dodge Ram Quad Cab pickup under the rear seat. The enclosure is seamless and airtight, with the correct internal volume to yield optimum bass response from the subwoofers. Hardware is included.

MTX Amplified ThunderForms reviews
The box the speakers arrived in was in terrible condition with absolutely no protective packaging around the speakers. It was also missing all wiring, mounting hardware and instructions. Crutchfield is working to resolve with the manufacturer, but I have no ETA. I'll update my rating once resolved.
Cons: Can't say yet

The Thunderform with MTX Terminator 10" subs is awesome! My only complaint is the packing - it was sent direct from the manufacturer, and the box arrived looking like it had been through the meat grinder (holes in the box, deformed on one end, almost all of the clips had come loose - only a few holding the box closed). I was worried that the Thunderform had been cracked, or something had gone through one of the subs - but it somehow managed to make it intact, didn't notice any scuffs or otherwise... got lucky.
Pros: Excellent bass response, fits like a glove in my 2012 Ram Crew Cab, easy to install.
Cons: Sub-standard packing.

The MTX speakers are junk!!! One didn't work at all the other the cone was busted and rattled. The box and amp are super nice. I took a set of old Kicker 10's I had and stuck in and it sounds great.

Cons: A little expensive, could have a little more power

I have had the ThunderForm unit in my 2002 ram since 2007,it's awesome. The system really pounds. I have a pioneer Head unit and a Pioneer 100 watt stereo Power amp installed. It really vibrates my mirrors and the kids get a kick out of the massage they get sitting in the back seat. I highly recommend this unit for your truck. It turns quite a few heads because not to many people expect this kind of great sound come from a truck. I have had a few people expect to see a large bass box sitting in the back and see nothing. It is hidden well.
Pros: Out of sight out of mind. You don't have to worry about anybody seeing your setup in the back. The box blends in well with the color of your interior. Fantastic sound. You won't be disappointed...
Cons: There is none.

First, great product once installed. Solid fit, great sound (w Kenwood deck). But I dock the product a star for sending the wiring harness with the power and remote swapped. I had to go get crimp pins to rewire the harness. How do you let a product go to the customer with QAing this (I blame the manufacturer, not Crutchfield. I called Crutchfield tech support and we had a good laugh over this lame QA, I sent them a pic). I could dock another star for the absolutely pitiful installation manual, as it makes no mention of having to wire the remote cable to your deck so the sub shuts down when you power down your vehicle. Good thing I know what I was doing. All of this aside, easy to do a clean wiring job and works great.

These subs work great. Hooked them up to my 05 Dodge Ram 1500 for bass. I was really happy with the results. Nice deep bass inside the truck, but doesn't have that "rattle 2 blocks away" sound outside of it. I ran the wires straight to my aftermarket cd player and didn't need to use the EBC. Instructions from Crutchfield made this an easy 4 hour job (including a new head unit) for a guy who has never installed a sound system in his life. Highly Recommended!!!!!
Pros: Easy to Install, Great Sound, Great Installation Info provided by Crutchfield
