im having a prob figuring this one out. what happens is when ever theres something electrical (lights, turn signals, fogs) turn on i hear a click sound through the speakers. When i use my turn signals i hear a click click click every signal. i was wondering if anyone knows how this could be fixed. i reground all my connections.

my current setup is i have all mids (2front 4*2's and my 2 6*9's) off a MTX 4244 amp. and i have my 2 10'' subs of my other legacy amp. i have an alpine 9815 headunit wired directly to the battery as it says in the manual.

any help would be appreciated.

 

just reviving the thread. other then a CLICK when i turn on anything electrical when i turn on my rear defogger i hear the winding sound of the engine through my speakers.

 

Bad ground/ground loop, try the system without the subs and amp and see what happens.

 

Try changing your ground point.

 

i have still the same result its almomst as if its coming off the engine, but i don't know why, i have 8.8mm accel wires, stock plugs, stock distributer i get a constant of 12-14v of power sent to the amps when the car is on. would just the plugs itself cause the interference?

 

anyone know what it could be, my grounds are clean, would an isolator do anything help?

 

Did that particular head unit come with a filter box on the power line? I have noticed that Alpines are noisy without them. Last couple Alpine units customers brought in that they installed themselves had the filter cut off and noise in the system. I installed a filter back in series on the yellow feed wire and it took care of the noise. Just a thought.

 

i don't think so, i know it came with a fuse near the head unit, but i didn't see a filter of anysort while putting it in. where abouts would i go to pick up such a filter, and are they hard to put in. would it be like an isolator you plug into the rca's before they hook up to the amp?

 

another question, since the deck is fused directly to the battery would i be able to hook the ground up to the battery to see if theres any interference from the engine, or something of that sort. would i just take the ground off the deck and hook it up? or would i have to go another way of doing so. Or grounding it directly to a battery be 'not a good thing todo'.

 

You can pick up a filter from Radio Shack or your local stereo/alarm shop. Try running a return ground from the amp to the deck and see if that helps.

 

so what your saying is loop the grounds from amp to amp to deck to chassis or deck to amp to chassis or something like that?

 

Your amps should have the same grounding point. Run a length of 14-16 ga wire or so from there to the same place your deck is grounded. Sometimes that will help eliminate noise. And if the screws you used to mount the amps are going through the chassis of the amp(s) and the floorpan(or any grounded surface of the car), then that will allow noise also. It is always better to mount a piece of wood or something similar to the car, then mount the amps to that, to help prevent any gnd loops through the chassis of the amp.

 

oh ok cause right now i have a different grounding point for both amps, i have one where the car jack would be and one near the bottom of the wheel well. and then my deck is grounded on the frame in the engine department.



thats how i have my amps right now, i have my mtx running my highs grounded to the inside of the wheel well, and my legacy 500 is now jensen 600 grounded to the upper mounting bracket for the jack.

so what i should do is take all the grounds and put them all to one spot. so say the wheel well or something in the back. but wouldn't the current continue into the other wires? like if i stacked them all on one screw or stud or something like that. or should they be in the similar spot but with their own separate screws.

 

ok i have reduced it to just the subs clicking when you hit the air condition on and off....any one have any ideas what it could be? (i have a ****ty pair of rca's going back woudl they pick up that sort of thing? they are the 3.69 for 15ft rca's black with cheesy tips) only thing i could thing of is maybe sub ground in trunk relocate it and possibly changing the rca cables


oh and the clicking through my mids with turns was a simple ground from the headunit to the frame (my bro wired it into the stock wirings, (its alpine 9815 and it needs its own ground and power lead from the batt) so i made a new ground for it put it in and bam works like a charm) but now the subs im gonna try relocating the ground see if that does anything but in the mean time any suggestions?



and its just the subs that are getting some sort of feedback when the ac switch moves along the bar from off to on. ive disconnected the subs to see if any other speakers have any feedback and nothing

 

definitely teh ground

 

yeah i thought so too switched it around and well so far to work and back no clicking so thats a good thing i think i finally have it set up properly

 

yea just make sure you get a solid ground and scrape any paint so your ground touches bare metal

 

where are your power versus RCA wires running in your car?

 

As ScrapMaker said, the noise is coming from your RCAs. Make sure they are not run with your power wire. Run the RCAs down the center of the car or the opposite side of the power.

If you're up for an experiment...bring a boombox with RCA outs and plug the RCAs from the "out" on the boombox into your amp. The power and ground are still constant, but the signal is now coming from the boombox. If the RCAs are getting interference from running next to the power wire, this should confirm that. If you do this, start with the boombox's volume all the way off and turn up as necessary.

 

the signal sound is due to your ground connection. just add a wire in that helps out with the ground. it will stop it. i had the same problem. i had engine static with my stereo when i bridged my side speakers together.

 

opposite sides of the car, i believe power is run along drivers side and RCA's along passenger side both wrapped in loam front to back.

noise signals had been solved it was a ground on my deck which i relocated and no problems since. lights work, no noise distortions, nothing shorting out which is good. so im pleased to say it works good now

thanks for all your help
