Overheating Head Unit
My head unit has been running very hot even at lower volume levels. I
have it grounded to the factory ground wire. I also believe that the preouts have been affected by the heat, as they no longer appear to send a signal to my sub amp. The signal had gone out once or twice before, but had returned for no apparent reason. I was wondering how to best avoid overheating of the headunit when I replace this one. Should I add heatsinks to the back of the unit? Should I add a larger ground wire and ground it to a point on the chassis close to the mounting location of the unit? As far as I can tell, this is not a wiring problem. Also, I'd like some opinions on a new head unit. I've been looking at an Alpine CDA-9830, it has everything I need in a unit and I can get it locally for $300. I've always owned Pioneer Premier units but I want to try Alpine because everyone I talk to says that they are quality decks that are really clear and clean. How do you guys feel about Alpine decks? Any other recommendations? I've been hearing that Clarion makes some good decks now too, which is really funny to me because I can remember when I was a kid, Clarion ranked right up there with Kraco and Roadmaster. Anyway, any advice you can give would be greatly appreciated. |

not sure about the 04 983X alpines.... but I do know that the Alpine 981X's
get plenty hot..... my 9813 has never shut down.... but damn.... I'll see how it heats up once I start using the PREAMP outs only... FHLH..... fuggers have a fan because it gets sooo hot in hear...... so take off all your clothes "Dylan X" wrote in message om... My head unit has been running very hot even at lower volume levels.

darn... was hoping it would run cooler once I went to preamp only mode.
have you turned off the internal amp on your? FHLH "FasDeth" FasDeth.removeme@coxdotnet wrote in message news:2S1Hc.81$ri.8@lakeread04...

FHLH Whether or not there is a load connected the amplifier will still be on, unless you can actually turn it off, and therefore will get warm. But it should run cooler than before. I've got a couple of dozen Crest pro amps that run remarkably warm when they are just in idle. Les |

Les You can cook with a Electorvoice P3000 at idle My alpine head runs quite warm using only the preamp outputs also, it's over 5 yrs old and it has never gone into protection. Chad |

Chad = It's just about that way with these Crest amps too. Luckily we are an indoor venue and the system doesnt have to work outside any, I am not sure if they could keep themselves cool enough.

The old iron 001 and 002 series run pretty cool. Haven't played with the new switchers. My FA's run pretty cool also, and I stomp the hell out of those I think the p3000 is still the hottest at idle I have seen with the exception of my class A tube amp They make me quite nervous, but never have shut down on me and I have used them a bunch around here, in the sun, at 2 ohms. Yuck. Chad |

Yuck. Chad At work we have quite a few Crest CA series, from the CA2 - CA12. Luckily in the main hall we moved over to Meyer so they are all self powered, but our smaller rooms and mixes 5-16 in monitor world are all Crest. This venue was my first major experience with the CA series and it really turned me off of Crest for a while. For their weight and consumption you just don't seem to get alot out of them. Keep trying to replace them with Crowns new I-tech line Doubt that will happen anytime soon though. Les |
