Simple, Inexpensive Subwoofer Add to Bose Audio in LT Trail Boss

Rylo02 · April 26, 2019

After putting in a TON of work into my 2016 z71 (stolen 3 weeks ago) I figured I’d simplify things this time around.

I bought a 2019 LT Trail Boss with Conv Package I and II so I already have the Bose audio with my infotainment system. I know there are mixed feelings on the Bose audio, but for me (38 and a big music guy) it’s more than adequate, aside from needing an additional subwoofer.

I won an Amazon gift card at work and decided to spend it on a Rockville RWS12CA. I’ve always used JL or Punch subs, so I wasn’t expecting too much from a $119 powered sub (including wiring kit) from some new company called Rockville.

I has it installed today from A+ Car Stereo in Tomball, Texas. I normally install all of my equipment myself, but with the truck being so new, and not a ton of video’s and info on builds for our trucks yet, the $100 to install seemed minimal.

I’m VERY impressed with this sub’s sound, power, and compact size, so far. (I’ve only had it for a few hours, so time will tell.)

It fits perfectly under the drivers side back seat. (See pics below.). I chose to remove the rear storage thingy on mine and run the all weather mats all of the way to the back.

I had them pull sound from the front door speakers and leave the factory sub as is.

The bass knob (not pictured) is installed right by where my right knee sits while driving.

Let me know what questions you have, and I’ll do my best to answer them.

Remember, this is NOT and SPL competitor or a $2,000 build. It’s a $220 mod that seems to be worth way more than that, as of now.

How is this holding up? Still happy with the purchase?

Looks good @Rylo02. I'm guessing you are in Houston. If you are, can you let me know which part of town your truck was stolen from so i can stay away from there .

@imadebogey Yes, I’ve had it in for several months and I’m very pleased with what it does. Again, don’t plan on shaking the car next to you, but it gets pretty low and really fills the cab nicely with bass.

While it doesn’t have the punch and the tight bass I had with my two JL Audio 10-W0’s in my last truck, it hits every note down to 30Hz and never feels overworked.

The good part is that the stock Bose sub still runs too. So for an upgraded stock stereo, and a $220 (installed) powered sub, I really like the amount of sound I get.
@truck_newbie It was at my office in the Galleria area and It was done by professionals. They were in and gone in about 40 seconds.

That sucks. I actually live very close to the galleria. 40 secs definitely sounds like a pro job. Sorry you had to go through that. I hope it doesn't happen to my truck but i guess if you are the target, there is probably not much you can do. Best of luck with your new one.
