The ATOM PRO removes that ceiling. Wire three 4 Ohm speakers in parallel on a single channel for a 1.33 Ohm load, or run four for a 1 Ohm load, and the amp stays stable while delivering full power. For SPL walls and big door builds, that means fewer amplifiers, simpler wiring and more speakers on every channel.\u003c\/p\u003e \u003ch3\u003eTuning and Installation Highlights\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eWide-range crossovers:\u003c\/strong\u003e High pass from 20 to 12,000 Hz and low pass from 45 to 12,000 Hz at 12 dB\/octave, so you can run midranges, tweeters or even a small subwoofer channel.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eWorks with factory radios:\u003c\/strong\u003e High level inputs accept 1.7 to 11V, so you can connect directly to OEM speaker wires without a line output converter.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFlexible RCA input:\u003c\/strong\u003e 0.2 to 6V input sensitivity matches almost any aftermarket head unit or DSP.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eHigh-current terminals:\u003c\/strong\u003e 4 AWG power input and 10 AWG speaker outputs for solid, low-resistance connections.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eClean output:\u003c\/strong\u003e 80 dB signal-to-noise ratio and a damping factor of 102 for tight, controlled sound.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eBefore You Buy\u003c\/h3\u003e \u003ch3\u003eIs the ATOM-400.4 PRO really 400 watts per channel?\u003c\/h3\u003e \u003cp\u003eYes, at a 1 Ohm load.

Bridged, it delivers 2 x 800W RMS at 2 Ohm or 2 x 620W RMS at 4 Ohm. The low pass filter goes down to 45 Hz, which suits a small subwoofer setup, but a dedicated monoblock is the better choice for a large bass system.\u003c\/p\u003e \u003ch3\u003eWill it work with my factory head unit?\u003c\/h3\u003e \u003cp\u003eYes.
