Service was fast! Price was affordable. I have not installed yet, however, I am satisfied with the ease of ordering.
Fit and finish was great 2016 street glide special
Bryan I got nothing but good things to say thx for answering my calls and emails And thx for getting orders fast
Ordered the product, received updates about the status and package arrived quickly.
Brian is a great guy. He got my order to me quickly. Was really helpful with all the accessories, and even with the mix up with the wiring harness he got the right one in the mail the next day . Will definitely be ordering more from his company.
Fast and very good communication helped me out alot made sure they where in stock and had them sent out same day I ordered got them few days later highly recommend
Bryan at TDS cares about car audio and it shows. Don't hesitate to buy from them. Bought my amplifier from them as distributor only allowed purchase in store and it was well worth driving there to meet him. Great guy and great shop!
I am very satisfied with the product as well as the cost. The amp is working flawlessly.
I have a Yamaha Roadstar with the Harley engine guard and lowers with the speaker provisions on them. I was running a set of Kicker KM654 Marine speakers paired with a JL Audio 280/4 amp bridged. They sounded alright. Installed 1 ground zero to I can do a side by side comparison. Ground Zero has a little more output, and a cleaner sound. When the sound of a kick drum hits, its more solid sounding where as the Kickers are kind of Tinny sounding. Super happy with my new Ground Zeros!
Sales representative was very helpful and provided my order status soonest. Great communication 👍🏽
The amp blinks after a few min of playing and was installed by professional stereo outfit here in Longview Tx. Big Daddys Stereo installed and its failing to work correctly. Can we send back for replacement amp?
You can’t beat the bang for the buck when it comes to Ground Zero and TDS was prompt with customer support and shipping. Highly recommend.
came on time and nothing was damaged i really appreciate TDS
Order Shipped and received next day!!!!!!! Wicked fast service!
