What Sets Overkill Customs Apart?

Customization isn’t the same as general auto work, and that difference defines our services. Overkill Customs specializes in high-performance, custom installations. We’re experts in building one-of-a-kind systems tailored to how you use your vehicle.

Here’s what sets us apart:

• Custom system design for every project
• Clean, factory-style installation work
• High-quality, performance-tested components

• Personalized service with clear recommendations
• Accurate quotes and reliable scheduling

Custom Auto Work We Offer

We build systems from the ground up, whether you’re after better sound, better lighting, or tighter security.

Our most requested services include:

• Custom speaker and amp setups
• Remote start and smart security systems
• Underbody, cabin, and specialty lighting

• Stealth-mode kill switch setups
• Integrated wiring and custom mounts
• Marine-grade audio systems for boats and watercraft

We also consult on product selection and system design to ensure your setup works the way you want it to.

System Integration by Trained Auto Specialists

Factory setups don’t always deliver what you need. Many stock systems lack the output, flexibility, or clarity that drivers today expect. Our team is trained to work with various systems, upgrading performance while keeping everything clean and functional. Most factory systems can be improved with high-end components that look stock but hit harder.

If you’re after a discreet upgrade, we know how to hide the gear without losing performance or quality. We take pride in blending form and function, so your upgrades feel seamless rather than slapped on.

What Can You Expect From a Custom Installation?

Your project starts with a one-on-one consultation. We’ll talk through what you want and what you don’t. Once your goals are clear, we’ll review product options, installation methods, and pricing.

Once approved, we handle the rest by:

• Sourcing quality components
• Prepping your vehicle

• Installing and testing each system
• Reviewing features and care tips with you

Most installations take a day or less, with more complex builds requiring a bit more time. We’ll always give you a realistic timeline; no surprises. Once the parts arrive, the rest moves quickly.

Premium Custom Auto Parts Without the Wait

We keep a range of popular custom components in stock and source specialty parts through trusted suppliers. This hybrid approach ensures speed without sacrificing quality. Thanks to our long-standing relationships with top manufacturers and distributors, the logistics are handled efficiently, which helps us get parts in faster and keep your installation moving forward.

If you’re looking for a hard-to-find part, give us a call. We’ll check our inventory or search our supplier database to locate it for you and order it in.
