Aftermarket radio

Jus did my whole system install yesterday. did new head unit and 2 12's. Today i had the headunit on for about an hr and it got really hot. Anyone know why this would happen? i am going to go through on wednesday and re wire it but i was jus wondering if anyone has any tips on why this happened? Thanx guys. You guys helped alot wtih my system thats why i am asking =)

i think heat is a natural effect from any electronic. my cd's get pretty warm too, almost too hot to hold to your face.
 
what equipment are we talking about?

the deck is a pioneer DEH-P7800MP

our dashes dont have a great deal of venting.  esp if you have the heat on, gets real hot pretty quick.  My buddy put a smal cpu fan behind the dash, and it sucks the hot air out of the radio cavity to floor on drivers side.

Are you using the radio's internal amplifiers?

Yes i am   Why?

Hillbilly. How did you do the CPU fan?

Using the internal amp will make a lot more heat, especially with aftermarket speakers, they use a lot more power.
 
 
The CPU fan can be done by running ducting from behind the head unit (wherever you choose to mount the fan) and wiring the negative lead of the fan to the nearest ground, and the positive lead to the remote turn-on lead.

I dont think the fan is really necessary......but a good idea.....

I'd only worry about it if the deck ever kicks into protect mode...

look at the heat sink area available to an external amp even a 2x25 and you can see how an internal amp plus cd transport and tuner buried in the dash is going to run hot.
 
I tend to buy external amps, and only use the preouts from a deck or at most use the internal amps for rear filll, but I can understand how sometimes budget is the determiniing factor too

O3Blazer, mind if I ask how you lifted up the rocker panels to route the wiring? Also, did you drill a hole in the firewall, or use an existing one for the power wire? Thanks!

what rocker panels? there is a groomet in the passenger side where your left foot would be. Pull up the plastic piece where u get in at then pull on that kick panel then pull the carpet back and you should see it. it is really big and its where the antenna wire is ran through.

the antenna gromet is above the pass floor area. about where you left foot would be.  Pull back the top of the carpet and its right there. adn the kick panels will just pull out.  remove the sill panel and then just pull

^ Thank You for simplifying it =)

cool, thanks!

decks have a protect mode? thats news to me......

The Alpine currently in my truck (used to be in my bosses Kia) once said something along the lines of "Hi-Temp" and that stayed on the screen until it cooled down... That could be why the fan squeals when it's cold, and the CD playing portion is iffy... lol
 
edit: And after checking the manual for my old Alpine CDA-9807 (bought in 2003-ish) it also had the same feature...

I just meant was there a specific way you took off the plastic panels at the bottom of the doors where the floor is. Most of the cars/trucks I've seen have screws that you take off in order to remove the rocker-panel plastic pieces where the door meets teh floor.

just use a flat head screwdriver to pry up an edge of em and pull up and they will come up easily.

thanks, yea, there were only 3 clips holding them down :)
 
power wire was easy once you figure out where the grommet is! thanks agian, sorry to stray from your original topic
