Get the Power You Need with a High Output Alternator
Is your factory alternator falling short of your vehicle’s power needs?
If your lights dim, your battery drains or your audio system cuts out, your factory alternator may not be enough. At Quality Power, we specialize in high-performance and heavy-duty alternators and starters built to handle more—so your vehicle works better, and longer.
Whether you need more amps for off-road lighting, a booming sound system, or a full rebuild for your truck or classic car, our high-output alternator upgrades are built to perform and made to last.
Best High Output Alternator for Maximum Performance
When you're looking for the best high-output alternator, it’s not just about raw amps—it’s about durability, fitment, and consistent power delivery. Our alternators are custom-built to meet your exact needs, using top-tier components and precision craftsmanship.
From muscle cars to modern trucks, we’ve got the upgrade you need—offering units that push 140, 160, 200, and even beyond 320 amps. Each alternator undergoes rigorous testing to guarantee top performance.
320 Amp Alternator Upgrade That Handles It All
If you’ve installed extra lights, a winch, air suspension, or run a dual battery setup, a 320 amp alternator upgrade could be exactly what your vehicle needs. Our 320A alternators provide a major jump in power compared to stock units—especially crucial for lifted trucks, emergency vehicles, and custom builds.
With proper fitment for most domestic and import vehicles, we offer bolt-on solutions that install quickly with minimal modifications.
High Amp Alternator for Audio Systems with Serious Bass
Your audio system deserves more than a factory alternator can deliver. Our high amp alternator for audio systems ensures stable voltage under high demand—keeping your subwoofers and amplifiers running at their peak without dimming lights or overheating your charging system.
We’ve built alternators for everything from daily drivers with a small amp to full competition SPL builds. Systems exceeding 1000 watts RMS demand an upgraded alternator for reliable performance.

Frequently Asked Questions
1. What is a high-output alternator and why do I need one?
A high-output alternator delivers more amperage than your factory alternator, giving your vehicle the power needed to support modern electronics, lighting, and audio systems. If your stock alternator can’t keep up, an upgrade is essential for performance and reliability.
2. Can my vehicle accommodate a high-output alternator?
Yes! We provide both direct-fit and custom solutions for a wide range of cars, trucks, and SUVs. Whether you’re upgrading a daily driver or a fully modified build, our alternators are built to fit like stock—but perform far beyond it.
3. Can I install the alternator myself?
If you’re comfortable with basic tools and vehicle maintenance, most alternators are easy to replace. We provide tech support and instructions. Professional installation is available for more advanced setups.
4. How many amps do I need?
It depends on your power demands. A basic system might run fine on a 140A alternator, but high-performance audio, winches, or off-road accessories might need 200A or more. Let us help you assess exactly what your system demands.
5. Do you offer warranty and support?
Yes! All alternators come with a warranty and our expert team is here to help before, during, and after your purchase. We stand behind every product we ship.
