OK OK, "this is a noob question" rah rah now shut up and read.

Put in my amp and sub in Today, well finished it today and I noticed when I turn the head unit off or the car off ( Same effect ) the sub gives a 'kick'. Now I noticed the sub works fine but I'm not sure about any of it. The polarity is correct, well on the amp to the sub - I'm sure. And all the power/grounding is fine too ( I even used a multimeter to get a good ground :shock: )

Any idea's?

If you're going to tell me to get back into my boot again I shall smite the into thy ground.

maybe its sending a final uncontrolled pulse to the sub when you turn it off?

:/

I don't need questions cause I can't answer them! I need answers!

what brand are your amps/sub
might just be when you amp turns off it make a thud noise which you can hear

Turn-off pop... Due to cheap equipment... Depending on where the issue is; You could run a small capacitor inline with the remote turn off wire for your amps that way the amps will stay on for a second longer so the headunit can turn off. Then the amps can turn off once there is no signal in the RCAs. Should solve your problem.

Otherwise... how are your grounds? Fat and close to the amp? sanded back the chassis well?

This could also be a problem inherent with your headunit (faulty/damaged) so there may be no easy solution.

This happens quite often with Amp installs, and not only with subs, but with speakers too.

There is still power running to the sub/speakers as the head unit is turned off and you get this pop/kick sound from your sub/speakers.

There are a couple of ways to eliminate this:

1. On most aftermarket head units these days, there will be an exterenal power wire coming from the back of the head unit. Usually Blue in colour, this wire sends power signals to Power Antenna's and remote Amplifiers. Use this as your Acc wire to your amplifier instead of a straight Acc wire from behind the dash and this should eliminate your problem, as it has a slight delay before supplying power to the remote device, and also turns the remote device a split second earlier before switching off power.

2. Buy a Amp Pop Eliminator! Basically a unit that sits within your RCA line and gives the signal a slight delay when either turning off or on to avoid those nasty pop sounds.

JB Hifi or Strathfield should sell these.

Jaycar AA-0424, the 2/1chan that won all those "awards" used with a JL Audio 10w3dv2 and a Eclipse CD5425 h/u. RCA's are stinger - don't know what model/whatever but have gold RCA terminals etc..

I used 2G power up to the boot and then used a stinger splitter/fuse block to break it into 2 4G's for amps ( one amp isn't installed yet ).

UGH Tim, DON'T say dud H/U! ( It's probably out of warranty ) Ground is a tad long, about 45-50cm and is 4G, it was the closest fat bolt, the only other closer one was the rear strut-top bolt and I didn't like that idea. The multimeter gave it as good reading as from the battery + to ground so I thought that was pretty damn nice.
