This amp cant push these speakers for a very long time, over heats and shuts off till it cools down. Thats if you push them hard. Had them professinaly installed yesterday had it shut off on me today. Then after about 2 min it cut back on. But great speakers and box they are crisp hit hard. I mean it will thump just dont turn it up to loud for a long period of time. Its 10 degress here so I know its not my mistake. It is a deal though. Just gonna find another amp. 800 or 1000 watt maybe.
