Edge DBX系列 EDBX2200.1D-E4 擴大機 D類 1聲道 單聲道擴大機 2200W RMS

Installed this in my truck last weekend and the Class D efficiency is no joke — my battery voltage barely drops even at full tilt. The big heatsink stays surprisingly cool after hours of bumping, and it pushes my subwoofer with clean, tight bass.

I was skeptical about the power rating, but it pushes my subs cleanly at 1 ohm without breaking a sweat. The binding posts are solid and easy to work with, and the overall build feels tough.

The "Big E" heatsink actually stays cool even after an hour of pounding bass, which I didn't expect from a Class D this size. It pushes my sub way harder than the old amp did, and the 2200w RMS rating feels honest.
