Zapco ST-104D SQ MINI 擴大機 4聲道 D類 可橋接 迷你車用擴大機

The speaker-level inputs made hooking it up to my factory radio a breeze, and it barely takes up any space under the seat. Even with the volume cranked, the sound stays crystal clear and never distorts.

I was skeptical about the power from such a small amp, but the bridgeable 4-channel design delivers clean, punchy sound that easily fills my SUV. It drives my aftermarket speakers without a hint of distortion, even at higher volumes.

Didn't think a Class D amp this small could push my front components and a sub this cleanly, but it does. Bridged it to run the door speakers and the bass stays tight even at higher volume. Install took maybe an hour since it tucks behind the dash.
