So I have recently put in 2 12 inch Kicker comps with my old audiofonix 800w amp and a 1.5 farrad capacitor, and I also have 4 gauge power wire. So When i turn on the car or turn the key over i get this weird distortion noise and whenever i push or pull a button (like the window controls) the subs make a pulsing sound... WTH could this be???? Someone please help me.

check your ground wire. where ever its grounded sand off the paint. fixed it for me

MBMCustoms

i have already tried this. no good

i really want to fix this guys.

The only thing that comes to my mind quickly is maybe trying a ground loop isolator on the RCAs that connect to your amp.

Are you tapped into the rear speakers and have a stock deck, or do you have an aftermarket deck?

I have a factory head unit with a toggle switch to turn on my amp and when I leave the amp on and shut the door mine makes a loud pulsating sound too, but I kinda like it that way I won't forget to turn my amp off lol.

lol, i have my factory radio, with a kicker l5 and a kicker 300.1 amp. I tapped into the rear speakers and did a high level input directly through the amp INSTEAD of a line out converter. WELLLLL when i start my car the damn thing will BUZZZZ really really loud untill i let off the key. Its Scared the Sh** out of me plenty of times, it doesent do it everytime. Gets me when i least expect it .

I have pictures in my Gallery

if its a pioneer its the pico fuse. otherwise try a ground loop isolator. ur getting a ground off balance thru those rcas somehow

MBMCustoms

it is the pioneer avic d-3. ^ what exact fuse are u talking about? im interested.

and i bought it at best buy and also purchased the 4 year service warranty, you think the warranty will cover it?

kkanowitz

I'm not positive, but I believe this fuse is internal and surface-soldiered, so I'd try a ground loop isolator first.

MBMCustoms

sorry im not too technologically inclined lol, what is this thing you speak of?

kkanowitz

Something like this:

Basically, if IIRC, a ground loop is a condition when the grounding of your RCAs is being interfered with electronically... So that interference prevents a clear signal to your amp, creating the noises you're hearing.

I say to do this first because its a cheap and easy way to solve it if that is even the problem, if not, it's the unit itself.

MBMCustoms

thanks for the heads up. i will deffinately try this before i try to get best buy to send it in.

do you happen to know if radio shack keeps those in stock by any chance? i would much rather just go pick one up at a local store

kkanowitz

That's just the first result off of google...lol. Any electronics store should have it, Circuit City, Best Buy, or your local audio shop.

MBMCustoms

ok thanks. i will let you know if it works.... and if not then F***

Another Question for you though! is there any specific isolator i need to buy? or just any? let me know quick cuz i may order one online

kkanowitz

All the ones I've seen are basically the same...if you can see a picture, just make sure there are two pairs of RCAs on each side. Preferably one pair should be female and the other pair male so you don't need to buy barrel couplers.

You might want to do it locally in case it doesn't solve the problem, that way you know you can get your money back easily.

MBMCustoms

well i can get one for 10 bucks with free shipping and it will ship tomorrow... should i? i mean 10 bucks really isnt going to kill me lol

kkanowitz

That's cool man...it wouldn't matter to me either. But I was just saying cause losing 25 cents gives some people a heart attack.

If its warranty take it to bestbuy they should fix your prob it should not do that and if you touch anything the service tech did I think the warranty is voided

MBMCustoms

i just dont want to have to take it to them. they take forever and **** something up everytime they try to fix something.

tony2toness/sc

But if they **** something up sue them lol but yea trust me if they screw something up its not your fault and you don't waste cash lol

MBMCustoms

i got what you are saying. if this isolator doesnt work then i will be heading to best buy for sure cuz its almost to the point to where i want to get rid of the system.

BCM

If the isolator doesn't work we could plug in my headunit and see if it still does it, just to make sure it's your headunit, or not.

tony2toness/sc

Just make sure it doesn't look like you were messing with it lol or else your screwed

MBMCustoms

ok sounds like a good idea.

will try

BCM

Gotta do it before Saturday though. I'm leavin for Florida and I won't be back til next wednesday.
