[QUOTE=revhi,Dec 26 2007, 09:42 PM]If you have a multimeter, check the voltage of the remote wire as it turns on.

You sure its not your amp just turning on and off. If i listen closely I can hear when my amps turn on. They make a little click.

Make sure your ground is unpainted and good to go. I had a Diamond m6 15" and a harrison labs 1600w 1ohm amp that drew 160amps of current. I had 3 ground wires running off it! Ss well as 2 grounds running off my component amp. Grounds are very important, you need make sure that its metal to metal..no paint or anything. The frame of the car is ALWAYS the best. Good luck.

The only way to ensure a solid ground is to take a multimeter and measure the resistance between your ground point and the negative terminal of your battery. It needs to be < 4ohms. Anything over that can cause popping.

The clicking is normal, that's the amp turning on/off. Popping the subwoofer is not normal, and indicates there is a static charge being built up somewhere in the wiring that is being discharged when the amp is turned off - i.e. a bad ground acting as a capacitor (stores energy, and then releases - in this scenario - 1) when it cannot store any more energy and the amp works somewhat like normal as power is flowing, or 2) when the energy source is removed)

Great info Neutered Spuntniks... so i would need a long wire to be able to connect the multimiter all the way from the battery to the trunk. i'll try that, thanks to all you guys for the help!

I can pretty much assure you that unless you've ground the interior panels to the chassis, you'll have approx 4ohms resistance. Most vehicles these days have an isolated interior, it's what causes a lot of noisy amplifiers and the popping

so if this would be the case, should i run a ground wire from the batery all the way straight to the amp?

now im dying to check what the resistance is on mine lol

That's a long ways to run a ground. I'm not quite sure the best way to solve this problem. With my friend's 2005 GMC Sierra, I just grounded the interior to the chassis and called it a day. That's an iffy thing to do as all the electronics depend on that ground, and if they depend on the difference in grounds, well...you could damage something...
