HU Sound goes out

Well 12 gauge is plenty for the Constant...I'm thinking this is because the N1 may pull more current the your previous HU's...voltage dropping below 11 isn't really a good thing...the constant doesn't have to be huge.

Not sure what the problem is though...not much of a HU freak

Sorry to hear about this though Caddy...and I have noticed that the spammers havent been around as much lately...good work

 

How about your ground?
It needs to be d same gauge is d constant and don't use d fact wire, go 2 d kick. Another thing is 2 use a relay on your ig wire.
30 to 12volts constant, use d one you have coming from d batt.
87 to d radio ig.
85 to ground.
86 to fact ig wire.
This way you pulling all d power strait from d batt.
Some cars have a screw on each corner of d dash for ground and if the screws are loose you won't have a good ground.

 

Are you sure your running a large enough wire? Pioneer, like many other aftermarket radios, use the constant to retain memory and for main power to the radio. The accessory wire just turns the radio on and off.

Check your constant wire, Its got to be to small. You said you used remote wire from an amp kit. Those remote wires are typically 16 or 18 gauge not 12.

If you are running from the batt to the HU, 12ga is big enough.

 

Bummer, I thought the caddy had a constant behind the radio, but not a switched wire. It uses data to turn the radio on and off.

Any way, you need an old analog volt meter. Check voltage with the radio running at whatever volume causes the problem. Check at the back of the radio. If the voltage drops, then go and check at the batt. If the voltage is much more stable at the battery, then the wire is to blame. If voltage drop is the same at the battery and the radio, then the battery is to blame.

Anyway have fun, it almost my bed time. I'm old remember

 

wow, i cant imagine ANY headunit pulling enough current to drop voltage below 11 volts!!!!! Well, start with what ranger said, run yourself a 12 gauge wire to the radio for memory and ignition, use the standerd bosch relay for the ignition and wire it up like ol rodny says (what the deal on all the d's btw???).....That will be a good sart...But WOW!!! i have never seena head unit that would not handle a factory wire to run it....my my how things are changing!

Just thought of one more thing........Is the HU running all your highs???? ANSWER THIS!!!!! and what sorta highs is it running??????I have another idea if you are.....

 

Never assume anything.

Assume means "makes an ASS out of U and ME

So please test then replace. Anyway have a great day

 

OK, i want you to try this, its cheap simple and if it does not work, you will be out a little time and about 1 buck!!! Go to radio shack, buy yourself a pack of 100ohm 1/4 watt resistors. get them home, now across each set of speaker outputs, install a resistor across the leads...you know, basically short out each set of speaker leads with the resistors, (but you wont hurt a thing).....I am guessing that the reactance of the caps in the speakers x-overs are causing the HU to see intermitttnat shorts.......DONT ASK!!! just trust me on this.....If it works great, if not, we will look into it further, but i am betting that this will work

 

No, not bad anything!!! speakers or HU......both i am sure are OK..... When "shunting" the resistors across eadch set of speaker leads, you are adding a 100 ohm load to the radio, far from a dead short!!!!! your speakers are 4 ohm, far closer to a dead short!!!!! what this will do is effectively make sure the radio does not see a reactive load from the x-overs in your speakers, which some HU;s have a hard time dealing with, the reactive load "freaks out: the outputs and shut it down....... follow???

 

Its an old "trick" that works most of the time......

 

NO!!!!!!!!!!!!!!!! LOL!!!!!!

The power "absorbed" by the little resistor is so minute that you WONT notice a bit of difference!!!

And actually the impedance will drop slightly, from 4 ohms per speaker to like 3.9876 ohms per channel (too lazy to do the math).....


Could the resistors get hot and melt or burn up? I have never seen it happen, but then the highest powered HU in my day was about 25 watts per channel........just do as i say son, and try it out. you can install the resistors at each speaker location where the wires hook up or behind the radio........If you want, run it hard after you install them and see if it works, then see if the resistors get too hot.....



Dont over think this!!!!!!!!! Just install a 100 ohm resistor in parallel with each set of speaker leads!!! YOU WONT HURT ANYTHING!!!!! IT WONT DEGRADE YOUR SOUND!!! trust me!!!!! i am an old fart, but by god i know what i am talkin bout!!!

 

ha ha!!! getin learned is always a good thing! I have come to realize that the older you get, the dumber you realize you are, And that aint no joke!

I hope the resistors work for ya...some of this new equipments out there is different in alot a ways, but, yet the same when you get right down to it, from your description of the problem at the start of this thread, I think it will work, of course not actually seeing it, i couls be wrong, but like i say, its cheap and you wont be out much if it dont work

 

R u using d GMOS-03 just 4 on star and chime?
the car has fact amp?
