static on speakers just started today

**skippy911** · 06-12-2005, 07:41 PM

I have a blitzsafe adapter hooked into the factory headunit and a 175watt invertor running my laptop to keep it nice and charged. Today I got in the car and now there is terrible static on all the speakers! I dont know what could have happened. I pulled the radio and the dash out and looked at everything and nothing was loose or broken or whatnot. I even bought a brandnew invertor and still static. Please help it is driving me crazy.

One thing to note is I can have the invertor on and the laptop on running through the blitzsafe just fine, it is when I plug the laptop into the invertor that I get noise.

Any help would be greatly appreciated. Oh and I am running the invertor off the cigarette lighter.

PS: I also noticed something strange that when I goto turn the car off it takes about 5 seconds for the radio to shut off now. I dont remember it doing that before

what kind of car?

2001 acura tl with stock everything for the sound system. I also tried hooking the invertor straight into the battery and still the static over the speakers. Now that does not make any sense, well err does any of this heh.

what kind of laptop? have you tried with another laptop? does it happen when you plug the laptop into the radio without plugging it into power?

I tried it with another laptop and same issue. It is only when the laptop is plugged into the inverter power that it happens.

i'm assuming you've checked the ground on the inverter?

"Stock everything for the sound system".. so you didn't have to buy any additional amps to drive any of the speakers. And it only happens when the laptop is connected to the inverter. On battery power you don't have the problem.

Did you try grounding the inverter's case (not just the ground wire) as well?

I have never had the inverter grounded before it just plugs into the cigarette lighter. how would I go about grounding the inverter's case?? It is an intec 175watt 300wattpeak inverter got it from walmart

If the interter's case is metal, run a wire from it to a ground point.

You may have to scrape off some paint on the inverter case to get a clean contact with the metal, and also make sure that you are getting the same clean contact where you are grounding it to the car.
