Question about Car Audio & Video

1 Answer

Crackling Whenever I turn my car to the "on" setting or turn it on completely, the head unit starts up as normal, the amp turns on, and it seems when the Subwoofers begin to get power, they start to crackle for a few seconds, sometimes longer, sometimes shorter. Then after the crackling/garbling goes away, the subs begin to work as normal, and I can crank the music up as loud as I want to with no crackling/garbling. It seems like when the Subs are initially getting power, they crackle and garble and have to "iron out the kinks" for several seconds before they finally stop crackling, then operate normally and I can blast away with no problems after that. So what is causing the Subs to crackle/garble only after I turn my car on? I unplugged the RCA's from the amp and it still crackled/garbled. I tried changing out my speaker wire but it still crackles unless I unhook the speaker wire from the enclosure/box. I'm worried because sometimes the crackling is alot longer and louder then other times. But eventually it has always gone away completely, and I have no problems after that until I turn my car off for a while and try turning it on later. (Should also be noted that it has only happened after I bought and hooked up a ported enclosure with subs already in it. It never did this when I was using my sealed enclosure powering two Subs and wired myself.)

So if you bought enclosures that are premade AND had the speakers installed, you need to see if there is a cross over network installed in them

SOURCE: i have a few problems. i have 2 amps and 4 subs.

The first amp, sounds like there is straight power going through the gain instead of it being limited. The second amp...hook the other subs up to it and see if it sounds ok. If so, then the subs are messed up. If it sounds the same, make sure the subs are connected correctly.

Without remote wire how to connect to head unit


If your head unit does not have an output for remote amplifier turn on, you can also use the power antenna remote turn on and run that wire to your amp. Or you can run a small 14 gauge wire from your battery along with your amp power wire, just make sure you put an inline switch somewhere in your dash area. This will give you the option when to have your amp on. 14 gauge wire from battery, to switch, from switch to remote turn on at amplifier. Switch will turn on and off amp. Make sure you turn switch OFF whenever you turn car off or you WILL kill your battery.

A number of days ago we put two plates of food in the microwave to reheat them. There was a snap, crackle, pop noise. We checked to see there was no metal object in the unit....there wasn't ...we know...


Are you sure the plates were Microwave oven safe? Some dishes have metal in the colors of the design. A snap, crackle, pop noise normally means there is metal present in the oven.

I installed my eclipse and the only problem im having is when i have the truck key turned forward it sounds good except you cant hear my subs that well and when i start it and turn it up once i get to a...


First off, you need to disconnect your battery immediately.. The reason for the feed back is you have a hot wire touching ground somewhere....probably a large sub speaker cable.....What will happen is the power going from the amp to the speaker or from the head unit to the sub will come into contact with bare metal and feed that current back into the system through the isolated ground. This will either reduce sound, or when the power is high enough, turn from a low hum to a heavy crackle. now if it crackles with the bass, more than likely its in your sub/amp configuration....if its constant or completely random then it could be anywhere in the system. check for bare, broken, or exposed wire.
GOOD LUCK AND PLS RATE THIS POST!!!!

Power off issue


Hello octoberburni,

No it is not normal for the amp to stay on when you turn the ignition off. And yes, it will definitely drain your battery if this condition is not corrected.

Use a multimeter set to volts and check between the ground connection (right connector) and remote turn-on connection (center connector) on the amp itself. You should have approximately 12V when the ignition and your head unit is on. And 0V when they are off. If you measure voltage when the ignition and head unit are off, either the incorrect wire is connected to the remote terminal, or the defect is in your head unit. If you measure OK, that is voltage present when ignition and head unit are on, and no voltage when they are off, then the problem is most likely in the amp itself. If you find voltage on the remote wire all the time, check to see that it is coming from the correct output from the head unit. Most aftermarket head units use a blue or a blue/white wire for the remote amp turn-on lead. Many (most) stock OEM receivers do not have a remote amp turn-on lead. But they may have a power antenna lead which will serve the same purpose. In any case, just insure that the correct wire is connected to the amp. It should have voltage when the head unit is on and no voltage when the head unit is off.

In either case, if everything else is still working with the amp, you can simply wire in a manual toggle switch to turn the amp off or on whenever you desire. A SPST (single pole-single throw) toggle switch is what you need. If the problem is in the head unit wire, put the toggle switch inline with the remote wire and mount it somewhere handy on or near the dash. If the problem is not in the remote wire, you'll need to put the toggle inline with the main power wire, the one marked "12V" (left connector) on the amp. In this case, you need to make sure that you have a heavy duty toggle switch, one that will handle more amps than your primary fuse. You may need to look under the hood for the fuse to check it's value.

Hope this helps.
