Not sure if this would help at all, but have you tried using a good sound dampening kit? If not I'd try putting a good one on the back of your cab and carpet over it.

 

I thought about it but I'm already pretty close to my steering wheel. So any thickness over the back wall would negatively effect my driving lol.

 

Hmm, Yeah got to love Reg cabs for that.. well sorry man that was the only thing coming to mind at the moment if I think of anything else I'll let ya know. Goodluck though!

 

Thanks man! I do think I'm gonna try wedging tennis ***** between the cab and the bed. That worked for some other people on YouTube haha. Kept the back wall from flexing.

 

I find it funny that you are willing to sacrifice your safety so that you can have a sub box in your truck. You do know sitting too close to the steering wheel drastically adds to how badly you get injured in an accident right? Just saying

 

Yes I know this but I'm still a couple inches from it. And if I'm in an accident enough to move my steering wheel in my lap I'll be hurt pretty bad anyway probably.

 

It's a collapsible steering column. The other car would practically have to reach the cab to shove it into ones lap.

 

Eeeeeeexactly what I was saying. Thanks Sean.

 

The most serious pickup truck injuries come from the rear. In fact, the most deadly accidents come from within the bed of the truck. I've worked numerous crush deaths from a refrigerator or other heavy object in the bed. Your rear end someone or run off the road into a ditch that's just deep enough to stop the truck suddenly and that load in the bed comes from behind and crushes the cab from the rear pinning the driver between the load and the steering wheel. I worked a 35mph decapitation not too long ago from a guys diamond plated 20" tool box. About a year ago I worked a low speed impact truck vs. tree and a fridge in the bed caved the bed and cab in. Pushed the bench seat forward into the column and killed the guy. I griped at my son forever about driving right up on the wheel like an old lady. Too damn dangerous. The column is designed to collapse from the bottom up in a front end collision. Just saying.....seeing senseless deaths suck! Not to mention, in an extrication, it's a huge, sometimes life saving bonus when you can simply slide the seat back to remove a badly injured driver. Throw in a speaker box blocking the rear movement of the seat and now you've added significant time to get you out of the truck and to the hospital in a timely manner. People don't understand the term "collapsible" steering column. They don't collapse inside the cab. Your face and airway does. If you happen to have your buddy in the truck when you wreck and he dies or is seriously injured because your seat was moved all the way forward for a speaker box, you can bet your *** that you'll be sued and spend the rest of your life paying for that decision even if the wreck is not your fault. Sorry to preach, but I've seen this stuff too many times in 20 years of EMS.

 

I appreciate the care guys. I'm an extremely careful driver. I also hardly ever haul anything big.
