[QUOTE="rallyben, post: 1001697, member: 562016"] ok so I have my setup and for the last 2 or 3 months I've been having an issue. I made a switch to turn on my stereo without wiring it to the ignition so I can play it with the keys out(info). When I turn the stereo on, it loads and does its thing and then the cd starts to play. Within about a second, the speakers make a couple popping sounds and then the cd continues playing. Now I think my head unit has been tempramental and causing this. Also, my sub does not always play at the right volume. Most of the time, you can barely hear it or it just doesn't work. When I wired the car up, I used the rear channels on the head unit for the rear speakers and used the front and rear RCAs for the front speakers and bridged sub through the amp. Occasionally, my stereo works great but most of the time, you can almost never hear the sub. I have a deep start marine 668 cca battery that has plenty of power. My system does this popping thing every time I turn it on and may times while changing songs, pausing, or messing with the EQ. I know it's not normal because it used to work fine. I don't know a heck of a lot about car stereos but I think it may be one of four things or maybe all of them. 1. Head unit is fried somehow 2. Faulty amplifier 3. the gauge wire for the amp is too small 4. my alternator doesn't have enough power For better diagnostic reference, this happens more often when the car is running, but it doesn't matter what the engine RPM is. Most of the time, when the car is off, everything runs normal, but it still pops between songs or starting up, most of the time. The sub still turns off or never comes on every once in a while even when the car is off. One other note, when I pause the head unit, it makes a random crackling kind of noise that has not pattern whatsoever. I did the entire install on my own, so that may very well be the problem but I'm hoping it's something that I didn't do. [/QUOTE]
