Customer service was great
Where to begin. We had an alarm installed with TDS and spoke with the owner Bryan. Right away I knew this guy was no B.S. and knew what he was doing. Great guy to talk to and work with. He actually tried to down sell us on the alarm for 450, but we wanted a digital remote since we have to park this car away from my home. So 600 bucks and ended up installing a Compustar instead of Avital due to our cars needs. After that he installed a remote add on to my Mothers 2017 ford escape. Again totally professional and reviewed my Mothers car and decided on a different installation then the one he was going to put in due to known conflicts with the year and make of the vehicle (not many will bother, just install it). One of the friendliest guys out there. We wanted this work done here because it is not like Car Stereo One or Tas where you are just a number. He backs his work and we will be going to him this summer for more work. If we could rate Bryan a 10 I would and you wont be disappointed. Get it done right the first time here!
Sincerely,
Frank Hubler and Delores Hubler
Very good price fast shipping couldn’t ask for more
I'm truly happy because the shipping was extremely fast and free and another company didn't treat me right but you guys made things great for me.
I spoke to Mr.Gibson regarding motorcycle speakers. I couldn't be happier with our conversation. He didn't sugarcoat the information and was accurate. I will be upgrading in a few months and will be using TDS again.
Brian really gives me good information about my motorcycle sound system everytime I call
Awesome better than I expected great product
So i installed in a 24 RG with a 1/2in spacer they fit just fine. Im running the harley 500watt amp definitely sound a heck of a lot better then the previous speakers I had on, you have to play with the custom eq on these bikes to keep the bass low cause harley sets all these with hea y bass, once you dial all that in the speakers are loud!
Perfect sounds good work done by Saul of linden
On time and no hassles thanks Brian
I ordered 2 sets of speakers on Sunday. They shipped them out on Monday and had them by Thursday. Thank you.
I was able to place my order online and it arrived a few days later. Tracking information was provided via email and the order arrived securely packaged.
No issues. 😉
I emailed the owner to change the order and he ignored my request. Instead of making things right he shipped out my order. Update: I got a call from seller and he made things right. Thank you Brian! A+ customer service :)
Great communication and product. Would definitely do business again with these guys.
One item arrived damaged. Replacement was shipped fast. Very pleasant service.
