As quoted by the technician who fixed my sound system, “[Diamond C Offroad and Audio] did the worst install job that I’ve ever seen in 27 years of working in the audio industry. It wasn’t one or two mistakes, they made a mistake at every point of the install”. Below are some of the “highlights” of Diamond C’s work:1. They grounded the wires to the paint (as opposed to scraping the paint and grounding it to the metal like they’re supposed to).2. They drilled a hole in one of the speakers.3. They broke another speaker.4. They didn’t provide enough space between the rear speakers and the door, so the rear speakers were constantly vibrating against the door (their mount should have provided more space).5. The tweeters were hanging by their wires.6. Three wires were disconnected.7. They JB welded the crossover to the door (as opposed to drilling it). This makes it more difficult to remove the crossover in the future.Keep in mind that I now live in Colorado and the technician who fixed my sound system has no reason to slander a shop in Louisiana.

These guys are great! Just got my full sundown system installed. More than I expected. This is my second truck that they did for me. Also got wheels, tires, and amp steps done on my other truck. Definitely recommend Diamond C to anyone.

Bought a few Sundown speakers. Great service. Thanks you guys!

Amazing service. Very knowledgeable. Love the way our truck turned out. Recommended rims and tires that were perfect. Installed a 6” lift on our Chevy as well. Couldn’t be happier. Definitely recommend these guys. This is our 4th vehicle we have had done. Stereo is next.

Diamond C does excellent work! Had a bed step put in yesterday and I love it!!

Had radio installed. Right parts not ordered so several trips. The installer even left mic behind dash on one trip there. They said Ineeded new nack up camera. The new back up camera doesnt have a clear picture at all. This place is a joke. If you use them be prepared for numerous trips and bad serivce along with poor products. I asked them to take everything out but they refused.

Awesome costumer service and very helpful staff. Will continue using these guys for future needs for my vehicles.

I got 2 welding rigs and a couple bumpers bedlined by Diamond C over the past couple years. I also sent a couple buddys their way to have their trucks done. Now that the liner is pealing off my bed, they wont warranty the work which had a lifetime warranty. I even offered to pay to have it fixed but they lied and said the machine was broken. Now I have to peel their stuff off and get it completely redone. That is bad business and I wont be going back there and will discourage anyone I know to do so. If they believed in their product they would stand behind it. If they cared about their reputation, they would take care of repeat customers.

Awesome place with an amazing staff

READ BEFORE USING!!! Beware!!!! Well, it all started out great..... decent price, decent sales team..... then you drop off the car and everything took a turn for the worst. He kept my Jeep overnight but told me it’d be done the day before. He turned into a jerk!!!!!! We didn’t even live in the area so it made it hard for us!!!! The next day i didn’t get it back until 1 pm..... my dog was left alone. Anyways, they messed up the alignment so i had to get it redone twice. Fast forward to a short 7 months later I’m having the death wobble!!!!!!!! I’m told by one shop, and now I’m too scared to use Diamond C to fix the issue. I’m using another shop....

These guys are amazing at what they do. Ive had them restyle and accessorize my truck, Jeep, golf cart and boat. True professionals and very talented at what they do. Ive never had better looking and sounding rides! Thank you Diamond C Offroad And Audio for taking care of me. Im a customer for life!

Great quality stuff and great service found everything I was looking for.

I absolutely love these people. they are all very nice and their work is great. they know their stuff too. i listened to how they spoke with and helped their other customers while I was there. Theyre the real deal.

Had a slight issue with my order but they offered plenty of fixes and solutions. It all worked out well and they were super easy to work with. I will be using them in the future.

Ordered light bars 2 weeks ago and was told they would be put on tuesday or wednesday. they still have not gotten the correct light bars in and are saying that they are all booked up and will not be able to put them on. when i asked for a refund they told me that they cannot give refunds for special orders or on credit card payments, but i was not notified before the purchase. This is not the first incident. When I ordered my bumper it took a week longer than expected to come in and they said they could not install it, so I had to do it myself.

Recently had a leveling kit and new tires installed at Diamond C in Gretna. Jay was extremely professional and friendly in taking the time to answer all of my questions. I also talked to a competitor in Kenner and the difference in how I was treated was night and day. Not only did Diamond C have superior customer service, they were also a little cheaper and would take care of the alignment as well after the kit was installed and the tires were mounted and balanced. Jay even stayed after hours to make sure everything was done right the first time and I was satisfied with the result. I couldnt have asked for a better experience. Highly recommend.

They were awesome. They was able to do our installation with no issues at a decent pricing. Will be going back to them in the future. good workers and nice environment. Thumbs Up!

I was only here once, but that’s all it took. It was like the guy behind the counter wasn’t there to answer any questions. Very short and seemed annoyed. He even took a call right in the middle of me asking about some LED headlights and a light bar. And that was just the beginning of what I was there to talk about. I came to spend money and they didn’t seem like they wanted any part of it. Needless to say, I left and went elsewhere. Spent about $6k setting up my Jeep how I wanted it. Too bad. Customer service goes a long way though.

If you have a truck that you want customized, these are the guys that can do it! They offer any type of customization you can think of. If you have a big boy toy, they will make it into a man toy!

Very helpful people

Very helpful staff and lots of different things to buy.

Had led lights that were partially working. Had them restore headlights to stock with high blue halogens. Wasnt to expensive

They have a good selection. Prices are ok in some things. If your looking for serthing things to make your ride better its a good place to look.

This is the place to go, they installed a FOX suspension on my Tacoma and a lift kit on my 16 F150, never had a problem with their work. The shop is clean and the staff is amazing .

Best place I know for nerf bars and other accessories.

Every time I needed work done on my truck they were very nice and do clean and professional work. I would recommend Diamond C Audio for any future work done!

Massive Runaround. Paid a lot for an install, was never called with an update, gave it back with no antenna, took it back, they said I had a bad radio, sent the radio off, radio works fine, I bet no one checked the antenna. Paid for an install and Im no closer to having a working stereo than the day I regrettably entered the place. However, Im still $600 out...Beware!!

Very unsatisfied poor work I have to go back tomorrow to get my truck they did not finish very unprofessional

Installers Broke a fuel system line and tried to glue it back together, while installing a air horn system. Never told us what happen but our Jeep did, displaying the check engine light. Bad dishonest work gasoline is something you dont play with and could have potentially seriously hurt my wife and family. We trusted this shop to provide workmanship in a professional manner and return our vehicle with all safety measures in place. The entire gas tank has to be replaced, once I took it to the dealership for an expert diagnosis. The funny thing is the management and owner just thinks that this situation wasnt as serious as they say and will not pay for repairs. I guess they have no disregard for the safety of the public and the customers it services. Pics posted on Yelp.

Prices are average. Although they do Rotate ur tires for free if you bought them there they cant give you a time or seem to actually have time to rotate tires.

Horrible customer service I want to this place to get new tires and tire sensors. After purchasing these products they didn’t come in on time and they couldn’t program the sensors to my truck. Wouldn’t recommend this place at all.

Very knowledgeable staff, Very easy to make appt in and out

Service is horrible, had my truck for a day amd a half to install a simple thing then called and said they didnt have time i had to go get my truck totally wasted my time, i would never buy r have them work on anything i ever needed r owned

Great service and friendly staff!
