    Default MTX Thunderform C15HC00

    So, for the longest time, I had a 12" sub strapped in the center of the back seat. I finally decided to upgrade to something more hidden and chose the MTX Thunderform C15HC00. I got the model with integrated amp and subwoofer, and it sounds absolutely fantastic.

    It may not be quite as bassy as the 12" sub, but it's hardly noticeable, and you can really tell that this sub/enclosure was really designed for this truck. The included sub and amplifier seem to so well together, much better than anything I've found by trying to do it myself. When they say that they engineer the design of the enclosure for the design of the truck, I'm inclined to believe them!

    Install was trivial, took maybe an hour. Just had to run power to the battery, ground out to a bolt under the seat and run my RCA and remote. For those of you with stock decks, they also have connectors to wire right in to the speaker connectors, and it uses the higher voltage to switch it on, so no need for a remote. (Though, obviously, I think you're missing out on a lot with the factory stereo; I'd think the headunit would be more important than the sub, especially if you're going to be paying $500 for bass anyway!)

    They also include a remote bass level knob that's optional, in case your headunit doesn't offer that functionality. The kit included all wiring needed, so I was very impressed. You have to move the floor jack under the seat, but that's it.

    Here are some pics of my install. Sounds great, and I have all my room back. I'm loving it!




    P.S.: I ordered mine through Crutchfield, since they've been good to me for so long. They also offer it in tan, along with a dual 10" sub version. I've heard the JL boxes are amazing, but $500+ and an amp is more than I was willing to spend on this little project. If you want to get $20 off your order, use code pfxsv-ffuhj-j7yud. Mind you, I'll get a $20 credit toward my next order. (I'm not quite a saint, but hey, we'd both like $20!)

    What did you pay 250 to 300? I never liked the MTX stuff but thats just me. I probably would have saved another $300 and got the JL Audio. Trust me if you hear your setup next to a JL stealth...you will wished you had.


    The specs say its a sealed box....it looks ported tho. If it is sealed and your other box was ported that is probably the difference you are hearing.

    The JL was available and quite a bit nicer, I will admit, but all the options for the Classic Silverado would either require replacing the center seat on the bench or taking out everything on the back of the truck and putting in two subs along the back. I like that this is basically nothing that's a major amount of work. I may be 23, but fibromyalgia has made projects like this a damn sight more daunting than they were a year ago.

    Yes there is a big differance between JL Audio and MTX in these type of boxes.. It's Fiberglass and wood for JL and Plastic for MTX...But true the Better JL will cost more because they are all made by hand sort of in Fla.. Not formed 20 at a time in a press...

    Good point. But for some people they can't tell a difference....like my wife...s she can't tell the difference between HD tv and I think she's crazy.

    I'm not denying the difference. I just don't need anything that badly. I'm just glad to get the distortion off of my speakers so I get some decent audio in the truck. With fibromyalgia, I don't have the energy to dismantle the center console to install a subwoofer like I once did. For the price, it's a nicely assembled kit that literally takes less than an hour to install without any major modifications to the truck.

    JL's do sound good. But you can have any shop fabricate a good box with a good sub for around $300.00, check out EBAY to.
