It's a hifonics amp and its wired to 1 ohm so its a true 1000 watts. ive got the subsonic filiter right under 32 or as close to that as i could get because that is what my box is tuned to. i believe the LPF is at 80. I havent smelled the coils or anything but with some songs i feel like i can hear something, but I was not sure if it's just something rattling, if its clipping, or if its me just being paranoid about blowing it.
