مضخم Zapco HB 84D 4 قنوات فئة D قابل للتوصيل 4x75 واط RMS

Installed this in my truck to replace a blown unit, and the variable crossover made tuning my component speakers much easier. It pushes my 4x6s cleanly without any distortion at moderate volume, exactly the 75 watts I needed.

The speaker-level inputs made wiring this into my factory stereo a breeze, and the variable crossover let me tune my door speakers without extra gear. It's been running cool and clean for a month now.

The speaker-level inputs made hooking this up to my factory head unit a breeze, no need for a line-out converter. Took a bit of fiddling with the crossover dials but once dialed in, the 75 watts per channel really wakes up the door speakers.
