View Full Version : Alternative Power Source???

Ok I managed to track down a MAJOR hissing noise from my system that appeared and was abnoxiously loud. it turned out to be where I had connected my hard wired radar detector and another electrical item rather dodgily connected to the power source that the deck uses, and fairly close.

After tapping it the noise would come and go, so instead of the crappy connector thing I had in there is stripped the wires and soldered them all together, as well as tidying up the wires and trying to seperate the RCA's away from everything else. It is much better now, however there is still some hissing, which also goes away if I turn the other connected items off, so they are defintiely causing the noise. I guess maybe they drain a lot of power or soemthing, but being close the the deck are causing nosie.

Soooo, im trying to find an alternative power source AWAY from the head unit. I know people say to use a multimeter and stuff, but I look under the dash and see a billion wires and really dont know what im doing. So does anyone know where I could find another accesory power under the dash somewhere away from head unit in a 2nd gen magna/verada???

Cheers,

Ollie

run a fused power line direct from the battery and use the accessory switch on the ign switch as a trigger for a relay to turn it on and off.

how about the power line for the ciggarette litter? not sure if thats on the ACC or ON.
but it'll still turn off with the car....

some cars the cig litter is on the same fuse as the hu so this may not work......

...or just run a fused wire off the back of the key barrel

my hard wired radar detector
i thought those were illegal lol
a bit off topic but can coppers detect radar detectors?
cheers

Don't think they can detect the radar detectors before the radar detector detects the radar they're detecting the radar detector with in which time you've been alerted to a radar and you've switched your radar detector off and slowed down.

Now thats a mouthful lol

radar detectors are illegal in every state...except W.A :D
radar detectors actually put out a signal regardless of wether they dect or not...
cops also have radar detector detectors and i think is about a $1600 fine and destruction of detector...it doesnt even matter if theyre connected/turned on either

Bring on radar guided cruise control.

Correct.

So, either I can run a line straight from the battery with a relay, however that sounds pretty complicated. I could use a 'fused wire off the back of the key barrel'. Why does it need to be fused but also, there are millions of wires comign from the key barrel, how do I know which one I want???

or you can do what i did and go extreme lol

i got sick of all the whines and static noises that i seemed to be endlessly chasing through my wires so i ran a 8g cable (fused) into the glove box, where it split across 4 fused wires that ran to switches infront of the shifter. one for the HU, one for the 4 channel, one for the 2 channel and one for the extra lights in and on the car.

got rid of all my probs, plus it meant that i could run the stezza without the keys :)

radar detectors are a shady idea, besides that some are laser driven now correct? also posting it on a public thread that you have one and are fitting it to a car=bad idea. Anyways back OT, you could run a direct hard line with a inline fuse up and away from the HU assembly. Also could try an RCA noise filter if all your speakers/sub are run off amps.

Don't see what is wrong with posting about a radar detector on a public thread, when they are perfectly legal and every 2nd car has them here in WA. What do you mean that some are laser driven now???

Anyway, what do you mean 'run a direct hard line with a inline fuse'? Getting power from where?

I guess I coudl get a RCA noise filter, but I would rather get rid of the source of the problem, and have also heard that they dont always completely eliminate the noise, and can reduce sound quality. However I am also getting a little bit of a whining noise even with my other accesories off which is coming from the engine as it is rpm dependent, so maybe a noise filter is still a good idea.

Ah, your in WA didnt know that one and i think some speed dectectors use a laser to bounce off the car, i remember reading it somewhere. What i mean by a hard line is a direct power cable from the battery to the detector with a inline fuse so you dont cook the radar detector. As for filters im using a DLS one with no quality loss (not that i can hear) and has removed all the hissing out of my system (was getting noise from an inverter).

are you any good with a testlight/ multimeter?
there should be only about 4-6 wires coming directly off the key barrel...just start probing till u find the one that turns on and off with acc
just make sure you put a fuse on the new wire coming off because goign from a thick wire to a thinner one...if it shorts then the main fuse for that wire will not blow....hence car fire
you should probably upgrade your earth from the battery as well...might get rid of a few noises

Cheers for the replies...

I did hear that there were now some laser speed cameras, however this was a while ago, and I thought I saw one once (more than a year ago before I got the detector) and havent seen them. Dont know how it would go with that, it does detect laser but I dont know how long it would detect it for, like if its pointing across the street, it would probably not work, but to be honest I dont know at this stage. Possibly only an illegal laser jammer would work.

I would go the route or hard line or whatever, however this will mean my detector and the other electrical item will be running while the car is off, which I dont want. I could put a switch, but I know im going to forget to turn it on/off, so I want to avoid that route.

Interesting about the DLS filter though, I guess that might be easiest, as I do have other noise as well like I said before, it it really does work that well. Where did you get it from and how much???

I can use a multimeter, but thought there were more wires than 6 in the barrel, so I might just have a play around. I think ill get a nosie filter, and if that doesnt solve it completely I will try this as well.

Ohh and I think I do need to upgrade my earth, considering its stock and I have a 4 x 125w rms 4 channel amp and a 460w rms mono. I have an earthing kit, which although will give me an extra 10kw, I have not got around to installing yet.
