    So I have a 2015 Optima with the UVO system. The stereo system is rather lacking, but I want to upgrade speakers and add a subwoofer possibly while keeping the factory head unit with the UVO system as I have a back up camera and everything with it as well. I have searched these forums and...

    Hello all, I'm struggling to figure out how to fix the problem I'm having. When I have music up at a decent level, sometimes the when the subwoofer hits it sounds like something back there is vibrating. I think it's just the cover on the subwoofer, but I'm not positive. Anyone else run across...

    Hello guys, so I have come to the conclusion that the stock speakers in my lx are a piece of junk lol.

    Zenclosures makes very nice, custom fit sub boxes. I had bought a couple of them for my GenCoupes, and saw that they had one for the Sonata, so I wrote to the owner and asked him if he'd make one for the Optima. A few weeks later, he sent me pictures of the box he made, and I placed my order...

    I found this company on the internet and decided to give them a shot. They had never made a box for the Kia, but after I asked them a few questions about it, they rented an Optima and made a mold. I was satisfied with the work they showed me and placed my order. They will make the box to your...

    Ever since I had my Sub mounted on my deck, the 3rd brake light would always rattle against the glass when the bass kicks in. I have a 10" Pioneer Sub but I've read from different posts that some people also get rattles from the stock Infinity Sub. So it stopped the rattle for me, Im pretty sure...
