Ground Zero Audio Titanium GZTF 4.0X 4″ 2-Way Coaxial Speaker System

I was looking for an amp like this and saw a video from TDS explaining the upgrades from previous model. Can't wait to get it installed and see how it does. Easy to navigate website and find what I need. Price was good, delivery was fast. First purchase but will not be the last.

I have had 3 sony radios in my roadglide. They are really good but diamond audio blows them away. Im have 4-full range cerwin vega 8" with a sound digital 800.4 amp this radio with built in dsp is amazing still getting it fine tuned had to turn amp down. Clean crisp sound it's a big investment money wise but it will impress you. Just wish it came with factory usb cord.

Customer service was great

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 :)
