Hey fellows..
I'm having some trouble with my head unit in my Jeep. Its an Alpine CDA 9851, it produces really great sound and works great with my Pioneer speakers. However, when I push the volume up around 19, 20, or 21 the unit cuts off, and reboots. I have no clue what is causing it to do this, I'm not pushing a whole lot of power in it, I think it should be able to handle 180 watt speakers easily.
thanks for the help,
~Jay |

i had that problem with another alpine unit a while back. it was my cheapo pos amp that kept cutting everything on and off.
you might wanna run you a larger power wire directly to the battery. i've heard that helps in this situation. |

yeah, larger gauge wire. maby upgrade the ground too. some of thoes Alpines require a lot of current when using the internal amp. the V-Drive ones from a while back especially. |

Yeah sounds like a voltage problem. If your running it off of the factory harness that sometimes isn't enough for aftermarket radios. Or a speaker can be blown, I know with Alpine and Pioneer Headunits if one or more speakers are blown they usually don't cut on or don't cut all the way up. So check the resistance on your speakers, and then upgrade your power and ground. |

The speakers are fine...as far as I know. But I'll check 'em out just to be on the safe side. I had the unit "professionally" installed by a local audio shop, the did the wiring harness and all that, so it might be the power and ground. Thanks guys  |

I Have a 1 fared Monster Cap with a yellow Top Optima Battery. 4 Gauge Monster Cable running through the whole car. At like volume 20 to 25 or songs with loud bass my head unit cuts off and back on. Anyone help? |

4 AWG isn't large enough for 1300 under rated WRMS. upgrade to 0 gauge.
do you have a HO Alternator to handle the 110 amps or so of additional current draw?? if not, get one or your gonna have some blown speakers, subs and burned up amps pretty soon. or just a dead alternator and fried battery if your lucky. |
