Question about Pioneer DEH-P4000UB CD Player
Ok so i've dealt with this problem for awhile now. I bought this system awhile ago: two 800 watt poineer subs, a 1200 watt sony xplode amp, two 300 watt speakers, and this head unit which ran my speakers. It ran great for awhile but then i started having trouble with what seemed to be the amp. For example when the volume was up higher it would turn itself off or short out. The fuse on the power cable to the amp blew so i just left it like that. The fuse blew because there was exposed wire...so i know that stuff is ok. So i then thought things were fine because i thought the amp was the problem, but the music was still shorting out at higher volumes. I think it has to be some sort of power issue because when the bass hits in the songs i can see a couple of my gauges on my dashboard bouncing to it. So when the bass hits the gauges jump! Also at night it shorts out at a lower volume due to my headlights. For example, if i turn my brights on sometimes the head unit turns itself off and then back on again. It has done that continuously before as well...so i had to take the faceplate off to make it stop. I took my car to autozone to see if it was a battery problem but they tested it and said it was fine, but he said the alternator could need changing. I told him about my situation and he said a new alternator wouldn't do anything. So i'm desparate and need to figure this out! I want to listen to music like i used to! What can i do?
I have a pionner cd plyer everytime i plug it into my car it shorts why is this ?

I would hazard to guess that you are running a speaker "ohm load" that is less than 4 ohms per channel. Or 8 ohms if you are running in bridged mode. You should NEVER blow a fuse. Re-check all your connections. Your "cutting out when the headlights are on" problem is due to low battery voltage to the amp. Use bigger wire on both your +12 lead and your ground lead. Make sure your battery to chassis ground lead is even bigger than your amps power lead. Make sure your amps ground lead is big, beefy, and short. And get a boost capacitor. When you have a huge amp in the trunk, you must treat it as if you are trying to run your engine starter from the trunk when it comes to the size of your hot wire and ground wire. Good luck.
