GZCF 8.0SPL 200mm / 8″ 2-Way Weather Resistant Speaker

Great product with fast shipping!

Excellent product with a small footprint.

Exactly as ordred

HKI processor ordered. Fast shipping. Item arrived in perfect condition ready to install.

Beautifully designed

These speakers look beautiful and are very well designed.

Installation is simple, but if required the product manual is available online.

The speakers sound very good running of a 1600 watt SD amplifier, but I’ll be doing some additional tuning and will let you know the final results.

Haven’t used them yet

I didn’t get a chance to use them. I returned them and got the better pair haven’t received them yet, but it was an easy return. The owner Bryan is a great guy. I really appreciate all his help.

Diamond Audio universal radio

The radio was received within 3 to 4 days of ordering which was perfect. My fiancé had the radio installed and he loves it. The sound quality is amazing. The sellers also checked to ensure his bike was compatible prior to sending which I thought was great!!! Thank you so much for your assistance with this purchase!

System Upgrade

The customer service with TDS is AMAZING. They are fast, reliable, and clear with their communication. Additionally, the purchasing process was seamless and painless. Outstanding prices for products and shipping definitely puts them above everyone I’ve dealt with. Make no mistake, if you need items, they are the ones to see. They also take care of Veterans and customers in other states (I’m a disabled Veteran in Hawaii).

I paid for 2-3 day shipping and got it a week and a day late

I'm just seeing this and was unaware of the shipping issue. I apologize for the late shipping. UPS is out of our hands and we do try to process and ship all items in a timely manner. I have refunded the shipping charges for you. I hope you enjoy the amp...It's a beast :)

The speakers arrived damage free and on time. Have not mounted them yet so i cant review the quality of the speakers yet. I will as soon as we put power to them.

Diamond audio mshd14

So far I love it boots up extremely fast and before you even know it android auto or Apple car is connected something I thought was odd is I didn't find a Bluetooth menu you do all of it from your phone I thought that was good and bad all at the same time cause anyone could connect to your bike stereo

Pretty happy

Least expensive kit I could find. Wish the grills sat a little flatter to the lid but over all I’m happy with it. Easy to cut templates. Wiring kit was very nicely done. Over all very happy.

I want the same speakers in 8"

I'd like to order the same speakers in 8" I love how they sound

More Bass

This Sub woofer is sweet, it replaced two 10 " Sub's. Big difference.

Great shipping time

Shipped and received in very timely fashion and great price on a great product!!

Received it with a small dent otherwise the amp is a beast

Great company very fast shipping %0D%0AGround zero speakers are awesome


I haven’t put these speakers in my bike yet but they look good and they’re lightweight compare to the speakers they’re replacing, also they shipped out fast, had these speakers the next day

Quick shipping. Haven't installed yet, but seem to be in good shape and better quality than stock.

Best customer service ever

Called after hours and just left a .message. Got a call right back. Gentleman spent 15 minutes listening to me explain the problem. Gave me a couple things to check. He called back about a hour later and got me straight. Needed new amp. Gave me a great deal on a nicer amp then I had installed presently. It was delivered in 2 days!!! Will get all my future stereo business!!!

6.5 gz yellow baskets for my harley street glide

Customer Service

I can’t say enough how well they treat customers. Even when you ask multiple questions to make sure it’s the right fit. I can’t thank k the team enough for guiding me on what to get to match current setup. I’ll continue to be a customer.
