I couldn’t be happier with the Behind-the-Seat Subwoofer Plug & Play System from Sounds Good Stereo. The entire setup is extremely well thought out, from the fit and finish to the plug-and-play wiring and included sound treatment.
Installation was straightforward and everything fit exactly like it was supposed to. What impressed me most, though, was the difference in sound. The bass is clean, tight, and powerful without being sloppy or overpowering the rest of the system. It adds the low-end response the factory stereo was missing while still sounding balanced and refined.
The sound treatment is also a huge plus. You can tell this isn’t just a subwoofer thrown behind the seat—they actually designed the complete system to work together and get the most out of the available space.
Just as impressive as the product itself is the customer service. These guys actually answer the phone, answer your questions, help troubleshoot issues, and stand behind what they sell. That kind of support is getting harder and harder to find. On top of that, they are true experts in what they do. You can tell you’re talking to people who genuinely understand vehicle audio systems, not someone simply reading from a script.
If you’re looking to upgrade your factory system without hacking up your truck or piecing together a bunch of random components, this is absolutely the way to go. Excellent quality, excellent sound, outstanding customer service, and a genuinely well-engineered product.
5 stars without hesitation. Sounds Good Stereo absolutely knocked this one out of the park.
With preconfigured Keyloc and plug and play harness made it very easy to add an aftermarket powered sub that totally resolves the factory DSP roll off that makes the bass weak. Huge improvement!
great product. Thanks
Product did exactly what was advertised !
I bought this kit to get more bass out of my 2024 ford f350 and it did not disappoint. The kit came very complete with everything you need to install it, it even comes with a couple high quality tools to make the job that much easier. The only thing I could say that they could improve is to have QR codes for the power wire and subwoofer install videos on the paperwork so it’s easier to access them. But other than that I’m super pleased with the product and the sound. Also the support team email works great and they get back to you super fast!
These harnesses are easy to use and work just as described. . There noise issues or Anc worry about or worrying bout getting a full range signal. Fast shipping great products. A little bit pricey bit you get what you pay for. Metra or PAC didn't even offer a hsrness to add an bass amp to the B & O SYSTEM or to the Bose systems in late model GM trucks.
Fitment was good and a easy install.
I called in and the salesman knew exactly what I needed, explained how it worked, and walked me through the install. He was extremely knowledgeable and very helpful! I received the kit, install was straightforward and simple- no guesswork. Once connected it fired right up and sounds awesome!! I couldn’t be happier!!
I am impressed with the quality and the effect of these block off plates. Shipped fast and well packaged; tins for the screws are a nice touch to help you during install. Supporting videos to show you how it’s done! I really wanted to do a A and B comparison so I added the door treatment and SGS block off plates and reinstalled the OEM Sony 6 x 9’s. Night and day difference. Without the plates they would add color the louder they got; with them they sound great. Will get these for next truck no doubt.
Clean install. Fully reversible. I have installed two Kicker subs and this harness makes it easier assuming you don’t mind removing the back seat upright. I go honestly can’t tell a difference in sound between the two installs but I have more confidence in this one over the other one
