Perfect for my ‘25 Wrangler
"I purchased the stage 6 bundle with the rear door subwoofer and the 6x9s for the soundbar to hook to my factory radio. All in all pretty easy install and it sounds really good. A major improvement. My only feedback is that I had to watch and switch between a couple different YouTube installation tutorials. The 24-26 model year is slightly different than the pre 24 install. Since I was replacing the soundbar with 6x9s and adding the sub there wasn’t one tutorial for a 25 that showed everything. I found myself referencing videos from Maxxsonics, dirt road cred, and bantam overland to see everything I needed. All that said. I would highly recommend!"

Totally Rocks!
"Although it took a lot of time to install, this sound system is better than I imagined it would be."

Amazing sound!
"Install was not too difficult but did take about 8 hours. Instruction videos were very good and made the job much simpler. Sound quality is way above factory and 10x louder. Be ready to adjust the amps, I turned mine about 3/4 of the way up for the speakers and all the way up for the sub and adjusted the frequency settings. Nice full range of sound with the 12”."

Excellent audio upgrade
"I finished installing the MB Quart system in my 2024 392 over the last couple of days. It was a time consuming, but not very difficult installation. I did it in 2 6 hour days, mostly because I was also using the opportunity to install a couple of other things in the Jeep while I had everything torn apart (hardwiring in a starlink and some auxiliary power outlets for overlanding). It could probably be done in 8 hours if I was only installing the MB Quart gear. The instructions and videos were helpful. There could be more info on setting up the AmpPro correctly, but I was able to figure it out after a little trial and error. I went with this set up (front dash/kickpanel speakers, soundbar 6x9’s, and stock sub retrofit with the 3 amplifiers) due to the reviews and the stealth look - it looks totally factory unless you start looking under the seat. I did have to make a small bit of customization as I already have my onboard air mounted under the passenger seat, so the amps couldn’t go there, but they do work under the driver’s seat. I did have to lengthen the power cable that goes to the battery and run the soundbar wires down the driver’s side b-pillar, but everything else went together easily. I find it important to fine-tune the amp settings once everything is back together, testing different music from acoustic to hard/heavy rock to find the right balance. This is something I’m still doing (it’s only been a day!) but it’s a significant upgrade to the Jeep’s “premium” audio."

Excellent kit!!
"Everyone I spoke with was above and beyond helpful and knowledgeable. The kit was built well and now installed sounds awesome. Only thing missing is to do the subwoofer upgrade. Trail Seven will definitely be our first call when the time comes."

I never knew how bad I needed this…
"Incredible upgrade. Jeep stock radio is anemic, at best. This is the answer. It absolutely rocks. Get the tailgate amp too, to complete the system. Difficult install, but watch the videos and talk yourself into it. If I can do it, you can do it. Very high reward value, for your effort. Adds smiles per gallon. Thanks to Trail 7 for answering all my questions before my purchase. Nice people to do business with. Very happy with product, and customer service."

Great sound, further work needed for sub to sound good
"Installation is involved but manageable in 8-10 hours by yourself! Sound is great from the speakers and big upgrade over the Alpine system. If you are using the factory sub enclosure more work is needed. Enclosure is thin so the back needs to be covered in dynamat to reduce rattles and give the enclosure some density, I also put some on the inside at the top of the enclosure. Package also does not include nearly enough polyfil, stuff the enclosure pretty full. Finally seal the sub to the box and ditch the metal grill, it rattles. If you do all that you will have a sub that hits strong and tight with very little rattles. Would purchase again!"

MB Quart System for Jeep
"I have a 2021 Jeep Jl Rubicon Unlimited and it came with the premium Alpine system, which is fine unless you want to open your top up, windows down, and maybe doors off, then the volume is severely lacking. After doing a lot of research, I settled on the MB Quart system (6x9 knee and soundbar speakers, along with 12 inch tailgate sub). I am not a audiophile, but the upgraded system sounds very good! It has good clean (not over powering) base and has clear vocals, even at very high volume! Also, speaking of the volume, you will have no problem hearing your music now, even with your Jeep wide open and going interstate speeds. I will caution that I had the system professionally installed and it took them 8 hrs and cost a pretty penny! Would like to also give a shout out to Dylan and Courtney from Trail Seven. Dylan answered several emails from me with well thought out answers and in a very timely fashion. While Courtney helped me with a small shipping issue and was very friendly and easy to work with! In conclusion, I highly recommend this MB Quart system and getting it through Trail Seven!"

Sounds Amazing!
"I installed this with an extra set of hands in about 8 hours in my 2024 4-door Rubicon. We followed the YouTube Videos. It sounds AMAZING! I've been telling everyone about it on the Facebook pages as well! Affordable and sounds fantastic! Also, I e-mailed and called TrailSeven with a couple questions, they were very quick to respond! Highly recommend!"
