You can buy great speakers and still end up with a system that sounds wrong, and Cal Cundiff proves it the hard way. We sit down with a dedicated DIY builder in the Tampa Bay area who turned a 2022 Ford F-150 into a legit sound quality truck using mostly OEM locations, a three-way front stage, and a DSP workflow built around MiniDSP and Dirac Live. The conversation starts with his current setup, then quickly moves to the real question: why do some builds image with a locked center vocal while others never get there? 

We walk through the messy part of the hobby that nobody posts on social media: missing power kits, learning wire gauge, reinstalling panels for the fifth time, and realizing that swapping midbass drivers won’t erase cabin nulls or fix phase issues. Cal breaks down how he learned crossovers, time alignment, and tuning basics, why Dirac Live is not “auto-tune,” and how careful measurements can make or break your final result. We also talk OEM-friendly F-150 opportunities like dash speaker locations and why simple system design often beats complexity. 

Then we get into the fun and the pressure: IASCA and MECA competitions, meetups as a tuning reference, and what it feels like to park next to cars you’ve only seen on YouTube. Along the way we hit common car audio myths, amp brand drama, and the beginner path that actually works: sound treatment first, install fundamentals, then learn to tune with tools like REW before you spend more money. If you’re building a DIY car audio system for sound quality, this is the roadmap we wish we had earlier.
