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. ThunderForm enclosures fill the nooks and crannies of your vehicle with low tones that stand out, but their factory look blends right in.
MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. Each ThunderForm fits and blends inconspicuously into your vehicle, so you get great bass without losing any space. They're made of high-density polyethylene resin to curb resonances they deliver bass that's tight, hard-hitting, and way down low. The airtight enclosure provides the correct internal volume to yield optimum bass response.
This amplified ThunderForm fits under the rear seat of your 2007-up Chevy Silverado or GMC Sierra Extended Cab truck. It houses a Terminator 10" sub and a cool-running 200-watt amp that's custom designed to provide optimal power without straining your vehicle's electrical system. MTX's Electronic Bass Control (EBC) lets you adjust the bass level from the driver's seat. A variety of inputs allow easy integration into your vehicle's sound system, and the included 20' power harness simplifies supplying power to the amp.

MTX Amplified ThunderForms reviews
3 might seem like a low rating but its average. Don't get me wrong, I love this sub but for the price and more for a LOC so I don't have to splice wires, it is kinda expensive. Not only that but MTX doesn't supply instructions on connecting this. They claim that they don't know what vehicle its going into so they can't supply instructions. I reminded them that this is a VEHICLE SPECIFIC enclosure so you know EXACTLY what vehicle its going in to. Anyway, I got tired of messing with them and ordered a PAC line out converter that plugs into the factory harness. Now about the SQ. That's a mixed bag. On some songs this thing hits good and sounds awesome. On other songs the bass is either muddhbor over lowering. It is absolutely necessary to connect and use the remote gain control or EBC as MTX calls it. I never had that issue with other amps. Gain was a set it and forget it deal. Probably has something to do with the factory head unit and its proprietary EQ curve. That being said, if you just want to compliment your factory system or just round out a mild aftermarket system, this is what you need.
Pros: Good SQ. Small size. Ease of mounting.
Cons: Non existent wiring instructions from MTX (Crutchfield to the rescue). Need to constantly adjust the gain as if it were a bass control.

Nice sub....it fits perfect in my 2007 GMC Siera Ext Cab and sounds pretty good.
Pros: Already amplified and has a remote gain that mounts in an easy to reach place for quick adjustment
Cons: The instructions are terrible There aren't any wiring instructions at all so if you've never installed amplifiers and subs before ya might need some help. The remote gain rheostat is a universal length and has the male end already installed so in my truck I had a ton of excess wiring that I had to roll up, zip tie and hide under the rear seat. Also, the speaker wire it's comes with only has RCA jacks on one end.
