I alrady tried it with the stock integra head unit and it didnt work. I had a line output converter(i think thats what its called) that was tapped into the speaker wires right behind the head unit. My subs worked with for awhile then it stopped working and i never knew why. I just got a new head unit and just figured there was something wrong with the way they were tapped into the speaker wires. I was messing with the wires to the head unit a little earlier and the bass would kick on for about 30 secs and stop. It did that a few times. The only thing i can think of is the amp is going crazy but the green light is always on so i dont know about that.
