I took out my 3rd row, swapped out my JL amp, because it was giving me issues, to a Rockford and added another 12 Pioneer sub box. I tried the MTX sub box, but I dixn't like how it sounded, and tore the foam surround. All in a day's work.View attachment 203421 View attachment 203422 View attachment 203423 View attachment 203424 View attachment 203425
Put a JL 10w in that Thunderform and I guarantee you'll like it. Then you can get rid of all that clutter. MTX subs suck.

Are you gonna keep the mtx?
I'm not sure yet, but probably not.

I actually have another box that was custom made for a Burb that has 2 JL's in it. Maybe I'll put that sucker in there.

Subs can be tricky. If you don't mind a big box then go for it but you still need to have the right box for the sub that's in it, along with the right amp and you need to tune the whole system. My 10" JL in my Thunderform hits real hard and it's completely stealth. My days of having a big bulky sub enclosure are way behind me lol. Especially when there's plenty of room behind the rear panel for a good 10". You should be able to sell that Thunderform for a good profit to someone that wants stealth since they are impossible to find now. Sell it to the highest bidder!

FIFY. I've got an MTX blue thunder 10" from about 20 years ago that still pounds. Had to re-glue to the surround to the frame a couple years back, but there aren't too many subs that old that haven't had to be repaired in some form or fashion that I'm aware of.

Think this is worth fixing? What's a good way? Refoam it? Guy said it used to hit hard for him. I don't wanna just toss it.

Soldered new wires to the knock sensor body harness. I replaced the sensor harness about 4k miles ago, and then the body harness got brittle and was connected by 1 strand. The Tahoe is getting old...

Time to detail and put her up for sale...

$30. Not really worth it to me. Maybe if someone wants it, just pay for shipping. I hate throwing away something someone could use.

Ha... yeah scratch that. Saw the reply about it in your other thread. Didn't realize they were so cheap now. MTX used to be a more expensive sub.

Oh yeah I forgot about those old ones. Somewhere along the line they went to shit and I have no idea to tell when that happened so I just won't buy one.

Haha, well my commute is going from 25 miles to 100 miles a day. I'd like to get my Cobalt SS running so I can enjoy the MPGs. I don't think I need a SUV anytime soon, and I eventually want a diesel Colorado.

Ok. I'm still going back and forth with it.
rubber cement and duct tape, its not pretty but it works...and for the folks that want to harp about Sound Quality, its not a $8000 UL12 or McIntosh or Hertz sub, just slap some rubber cement, a layer of duct tape, then some more rubber cement, and one more layer of duct tape to that surround, add some 1/2" spacers, and hide that hideous surround behind the panel and call it a day
