rpms drop at idle help?

because power doesent run straight through the HU... the HU creates the 12v turn on signal, it generates a 12v signal, with extremely low current. the 12v does not simply pass through the HU and go to the remote wire, its part of what the unit itself does. my particular head unit at the time was capable of three 4v pre-outs, and 4 channels of 45watts of power. do you think that these 4v pre-outs and 45 watts of power were generated by the cars 12v system? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif . remember when i said think outside the box? you are still stuck in it. the HU generates that 12v signal, it is completely independant of the cars 12v charging system. do you think that your amplifier running your speaker is putting out 12v? no, its probably putting out well over 12v, with less current going out of it than is coming into it. while it is dependant on the cars electrical system, it still runs INdependantly.


because we didnt think it to be as serious a problem as it actually was. and i, for one, never knew of such a device. but hey, hindsight is 20/20. i lived, i learned(something you should try //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif )

i was talking about a remote turn on lead, not the rca's, but alright //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

and thinking outside the box, doesn't a hu require around 12 volts for it to even power on itself?

i was using it as an example that i hoped you could understand better.

nope. it, again, is supposed to be run at 12v, but does not require it to run.

im through arguing with you. im telling you, from personal experience with alot of equipment, im not arguing theoreticals... and i am telling you what will happen, what will not happen, and what has happened. not what could happen, or what should theoretically happen. everything i have learned from real life examples, and seeing it happen. so good luck to you, try to learn some stuff on your own and not live your life on the internet. go out and test this on your own, see what happens...

and if thats the case, and its well known that the amp won't shut off from low voltage, why don't you take precautions to stop that from happening, like getting something like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7539467807&category=4660

Because it would shut off your amp while still in a safe range, IE 11v?

No. Perfect example was today. I left my ignition on most of today to power my podium. I go to move the truck and the starter wont even think about moving, I get ignition lights that dim when I try. Now, if I had 12v the truck would have started wouldnt it? DOH! Yeah, most HU's will run on 9v, some require 10.

no, i've been fortunate enough to take all the right precautions and never "burn" a vehicle down in any of my installs. but then again all the vehicles i've delt with have had healthy electrical systems(i.e. rebuilt alt's/newer alts, new batteries, and big 3 upgrades) i myself never did it on my truck till recently, but dimming lights weren't a problem till replaced my stock hu with a panisonic....guess if you have a 80 amp alt though, you should rethink putting a stereo in your vehicle.......

ive heard about your "install skills"... and all i can say is, i have no worries about you trying to lecture me about making sure your electrical system is up to par. good luck kid //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

P.S--if you havent noticed, you have two people trying to help you learn something here. and im pretty sure that out of the two of us, one of us knows what we are talking about, and the other (this is me) has personally learned alot from the other...

I bet you'd be more prone to electrical system problems if you had larger than a 500 watt amp.

yea i'm trying to learn how to not screw up, and so far i've done a good job of not doing it, fusing everything properly, putting barriers between wood and metal(i.e. the amp and the box, there actually are 1/8" spacers to keep the amp that much further from the wood) and having 2 fuses on my system, reguardless of what iban thinks the amp puts out, if those cvr's "bump" like that off of 500 watts rms, then i really did something right //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
