"I feel inspired to share my experience with Reus Systems. I bought a used Tesla Model S 70D in February (2018) and absolutely love the car, possibly more than I have any other car in 30+ years of driving. However!... For a car that originally sold for $92,000, the stereo system COMPLETELY lacks any bass or fullness whatsoever! I was actually quite shocked at how underwhelming the stereo system was. I used to put way too much money into my stereo systems and listened to a lot of obnoxious bassy music in my earlier days throughout the 90s. In the last 10 years or so, I've started listening to a lot more talk radio and when I listen to music, it was certainly less bassy because I haven't had a stereo that sounded all that great. I actually never thought about why the music I would listen to while driving had changed until upgraded my Tesla stereo about 2 months ago. When I first got the car and noticed that the stereo was lacking, I started to look around for upgrade options. Obviously, you can't switch out the stereo itself since it's integrated into the Tesla's computer, so I looked around for speaker upgrade options. From checking the Tesla forums, I noticed that they were 2 manufactures of drop-in equipment, Light Harmonix and NVX. Both of these appeared to make products that you buy, have shipped to you and install. The other name that I saw a pop-up was Reus. However, there wasn't much information on a specific product that they install, but more so information on how they upgrade your stereo by adding their sub woofer with an enclosure, replacing some of the stock speakers, possibly adding others, etc. I also decided to look on Yelp.com and check to see if there was any shops around my area, Orange County, CA, that have done multiple Tesla upgrades. As luck would have it, I came across Reus again and found out that they are only a few minutes from my office in Orange, CA. The reviews were definitely good on yelp, but there were only a few. So I drove over to their office to talk options and met Cliff, the shop manager. After finding out more about what they offered and looking at all of the reviews on the Tesla forums, I decided that I wanted to go with their package over the other manufacturers that made a prefab option, partially because I have no idea how to install the equipment. I dropped off the car, told them what I wanted and picked up the car a few hours later and Oh My God! I was absolutely 1000% shocked by the amount of bass their single 10" sub produced! Yes, the general sound of the stereo also improved no matter what type of music I was listening to, but within a day or two I found myself constantly searching for old-school hip-hop, rap and R&B, the stuff I used to listen to in my 88 CRX Si with twin 12 inch subs and two obnoxiously large amps. Since I picked up the car from them about two months ago, I have completely changed what I listen to on a daily basis when I'm in the car, for the first time in probably 10 years. I am now that 47-year-old guy with the big gray beard thumping all sorts of EDM music way louder than I should be. I did listen to a friends tesla that was upgraded with the NVX subwoofer and it sounded good, just not as good as good as my car, in my opinion. I also have 2 friends that both have a Model S and both were floored how much better my car sounds than theirs. For as much as these cars are sold for, they really should have a much better stereo system. However, they don't. I am super happy with what Reus did to my car and yes, I would recommend it to any Tesla owner."
