HIA-RCA3 | Amplifier Input RCA Adapter

Picture This: The Install That Actually Goes According to Plan

You know that moment when you're staring at a wiring job and thinking about all the ways it could go sideways? This isn't one of those moments.

The HIA-RCA3 is a 6-channel RCA adapter harness that connects directly at your amplifier—true plug and play as part of the HDF8 system. Whether you're tackling this in your own garage or you're a pro installer knocking out multiple jobs a day, this harness is about getting it done right, fast, and clean.

Here's what makes this work for you: No splicing. No custom wiring. No callbacks because a connection came loose three weeks later. Six channels give you the flexibility to build out whatever system you're envisioning—front, rear, subs—all with connections that are solid from day one.

If you're doing this yourself, you're looking at a professional-grade result without the professional-grade headache. The kind of install where you step back and think, "Yeah, I did that."

If you're an installer, you already know what this means: faster turnaround, happier customers, and more time to focus on dialing in the sound instead of troubleshooting connections. Your reputation is built on clean work that lasts—this harness delivers that, every time.

This is the upgrade that's ready when you are. Whether it's your personal build or your next customer's dream system, you just plug it in and move forward.
