Zapco ST-1000XM III 擴大機 單聲道 1聲道 Class D 超低音擴大機 附遙控器

I’ve been dialing in the bass with the variable electronic crossover, and it makes my sub hit exactly how I like it. The remote is a small but handy touch—lets me adjust from the driver’s seat without reaching back.

The subsonic filter is doing exactly what I needed to keep the lows tight without muddying the midbass. The aluminum chassis feels solid and runs cool even after an hour of heavy play. Only wish the remote had a bit more range, but the tuning options make up for it.

The variable subsonic filter is a nice touch for tuning out unwanted frequencies, and the new aluminum chassis feels solid. Only reason it’s four stars is I wish the remote had a bit more range; otherwise, it powers my subwoofer perfectly.
