MORE POWER FOR WHATEVER YOU'RE BUILDING OR UPGRADING
Custom high-amp electrical builds
For sound systems, electric upgrades, and specialized power demands
Your Stock Electrical System Wasn't Built for This
When you add serious upgrades to your vehicle or equipment, your factory electrical system often can't keep up — and that causes real problems.
Your new sound system is browning out or draining your battery because your alternator can't handle the load.
You've added electric components to your pickup or RV and your charging system is struggling to keep everything powered.
You're not sure what amperage you actually need or who can build a solution for your specific setup.
Generic off-the-shelf parts don't fit your application and you need something built to your specs.
You've been told "we don't do that" by shops that don't have the experience for custom electrical work.
Upgrading your vehicle or equipment should be exciting, not a headache. When the electrical side becomes a problem, it takes all the fun out of it — and we want to fix that.
Custom High-Amp Electrical Builds
Designed Around Your Specific Power Needs
We know that no two builds are exactly alike, and a one-size-fits-all solution rarely works when you're pushing beyond stock electrical capacity. With over 30 years of electrical expertise, Adams Auto Electric has the hands-on knowledge to engineer and build custom alternator and electrical solutions that match your exact application.
Tell us what you're building, what you're powering, and what you need — we'll design a solution that works and build it right.
Our Custom Electrical Solutions
Every custom build starts with understanding exactly what you need. Here's what we specialize in.
High-Amp Alternator Builds
When your stock alternator can't keep up, we build a custom unit designed to your exact amperage requirements. Whether you're running serious audio equipment or heavy electrical loads, we engineer the output your system actually needs.
Audio System Power Upgrades
A high-end sound system demands more from your electrical system than a factory alternator can deliver. We build custom alternators specifically matched to your audio setup so you get clean, stable power without voltage drop or battery drain.
Electric Add-On Power Solutions for Pickups
Adding electric components to your pickup — whether work-related or recreational — puts new demands on your charging system. We build custom electrical solutions that handle those added loads reliably and safely.
RV & Motorhome Electrical Upgrades
Modern RVs and motorhomes are increasingly loaded with electrical demands. We design and build custom charging solutions that keep everything running whether you're plugged in or off-grid.
Specialty & Industrial Custom Builds
If you have a unique application that demands more than standard parts can deliver, we can help. We work with agricultural, construction, and industrial customers on custom electrical builds tailored to demanding environments.
Built for Your Application, Not Someone Else's
Custom-Matched Amperage Output
We build alternators to the exact amperage your system demands, so nothing is underpowered or overworked.

Frequently Asked Questions
Here are answers to the most common questions we get about our custom electrical build services.
How do I know if I need a custom alternator build?
If you've added significant electrical loads — like a high-powered audio system, electric winch, or accessory upgrades — and you're experiencing dimming lights, battery drain, or voltage issues, your stock alternator likely can't keep up. We can assess your needs and recommend the right solution.
What amperage levels can you build to?
We build custom alternators for a range of high-amp applications. The right output depends on your specific system and load requirements. Contact us with your setup details and we'll tell you exactly what you need.
Can you build a custom alternator for any vehicle type?
We work across automotive, truck, RV, marine, and other platforms. If you have a specific application in mind, reach out and we'll let you know what's possible.
How is a custom build different from just buying a high-output alternator online?
Off-the-shelf high-output alternators are built for general applications and may not match your vehicle's mounting, wiring, or specific load profile. A custom build is engineered and assembled specifically for your setup, which means better fit, better performance, and less risk of premature failure.
Do custom builds come with a warranty?
Yes. Every custom build we produce is backed by a full warranty, the same as our standard repair and rebuild work.
How long does a custom build take?
Timeline varies based on the complexity of your application and the components required. We'll give you a clear estimate upfront and keep you updated throughout the process.
