That's a nice amp! Couple years back I was at a car swap meet, there was a young guy there with 2x pretty huge silver amps, I went for a look, they are big brushed alloy 4ch Schneider amps and have crazy features like a subsonic filter from 10-80hz, they have 160A of fusing each!! I had to take these amps on the spot, and when he asked for $50 each for them I could have squealed like a little girl lol. Seriously, these Schneider SPA4000.HC 4ch amps are NICE.. There used to be some website that had them listed a few years back, it was car security or something, it had the ratings and price etc. I love these amps, like not only the features of them, but I ended up comparing my current Rockford Elite 8004 to them and I couldn't hear a meaningful difference so I sold my RF 8004 and 20001bD.. To this day I have them running my Morel Elite 6 and MT23, and I've got plenty of other amps I could use instead if I wanted, I have 4x Alpine MRV1505, 2x MRV-T757, I've got a Orion HCCA 3000.4H that is 450wrms x4 class AB lol, I've got a damn ARC 2300SE!! Surely that tells you that these amps are no joke. They have notched metalized crossover pots, large range subsonic filter, bandpass filter (I think they go up to 3 or 5 K), 1 ohm stable like my RF8004 but that had a 150A. I think they are rated 750w rms x2 @ 2 ohm (BTL). 500w rms x2 4 ohm (BTL). 500w rms per ch x4 @ 1 ohm. They definitely seem like they are designed to run multiple subs. They run 3 pairs of 540Ns per channel! My MRV-1505's only run 3 pairs of 540N's per ch, and they are "rated" 900wrms @ 4 ohm 0.003%, 1500w rms @4 ohm max!! Sick amps. Where did they come from? Where did they go....?

S&I South Korean designed and built. Very similar to American Bass VFL 80.1D
