Having problems with your Cars & Trucks ?
I have a Pioneer 5400t amp hooked up to a 10" 400w sub of unknown brand. The system was working perfectly for about a week, then I noticed the sub wasnt working. I blew both 30a fuses on the amp. I replaced them with 2 new 30a fuses. At that point it started to turn on and off whenever it is connected to the sub. the sub is a 4 ohm sub with single voice coil. I have it connect to the power with 8gauge wire, and a 50a fuse. I have a brand new battery and an alternator that is about 1.5 years old
Your best bet is to buy a cap. A capacitor is an external battery booster like device. It boost power to amp. The thicker the wire the better. Power and ground. Shorter thicker ground wire the better. Make sure it is not on a painted surface. Scrape down to metal surface!!!!
