OK I have 2 rockfordfosgate p2s 12" in sealed box WITH kenwood 650 watts. My problem is my subs can't be turned up high or they with make a poping nosie and cut in and out. Also my rca's are what turns my amp on. Now I know that's not right. My rca's connected to the amp. One is in output, one is in input and it hits but maked a poping nosie if it get to loud. When I plug the rca's to just input the amp doesn't even turn on. But before I had them in my other truck that caught on fire and had to put it out with the water hose. And yes the amp got wet but the car wasn't on when it happened that might be the problem just wondering if anyone knows why its poping and I haven't tried another amp yet.and it was like three weeks before I gave power to it. And it should turn on with out the rca's if anyone could hellp or need more info. Just post or something.
