QR Code Link to This Post
🔊 Two 12” Diamond Audio Subwoofers
📦 Custom-made trunk box – solid build, fits most sedan trunks
🎚️ Diamond HEX Series Amplifier – serious power and clean output
Everything works perfectly and sounds amazing. These aren’t cheap knockoff subs — Diamond Audio is a high-end, audiophile-level brand known for clarity and deep bass. Only selling because I'm no longer using them and want to free up space.
🛠️ Minor cosmetic wear from normal use, but no performance issues.
Local pickup only – located in Walnut Creek.
