Running 4000watts max off these 2 mafkas, have them wired to 1.34 ohms, barely turned up a quarter on amp and they just slam, no problems yet, I’ll try keep an update on it as the months go on, you just gotta do your studying on your wiring job and what works best they maybe cheap but can compete with pro amps when set up properly
