So I bought this to put to a RF 2000w 10" sub. wired it for 2ohms and and max everything it barely moved it! I was a bit upset, I took the speaker out and wired it at 1 ohm and got it to actually play. Mind I wired to this with 1/0 wire to a 12 farad cap. I had higher hopes for it but it has potential, when I hooked it to a 500 w PPi 12 it damn near blew it out of its basket and I had to turn the amp down to almost nothing. This amp also has a switch to make it 180 degrees for isobaric boxes so two of these would be awesome for a double set, one at 180. I couln’t give it five stars because it it is not as powerfull as it claims 4000@ 1 ohm, 2000@ 2 ohms, and 1000@ 4 ohms. But… actually bumps that 2000w 10 " at 1 ohm and that is saying something! Most people don’t try o push huge wattage woofers SO if you want a great priced amp that will move your 500w rms speakers to their limit buy this! I think I might pick up one more and set it to slave and see what it does to this 10" I would still be way under the cost of a RF class D amp!
