Hi,

I tried to search for a similar topic but could not find one.

I installed an amp and 12" sub today in my NA Fairlane - works very well for the price..... but one problem:

When I switch the car off the green light on the amp stays on. I initially wired it to the amp remote cable, and then the antenna - still would not go off. The strange thing is that the remote cable is recieving 12volt from the amp, not the other way around. I detached the remote cable, and switched the power on/off options to the two other than 12v - still not working....

I had a hard time installing it - here is the configuration:

Kicker DX100.2 -
VDO head unit..
Kicker boxed sub..

Wired the power cable from the battery, through the boot release hole in the firewall and through the drivers side floor to the boot. (inline fuse near battery)

Wired the speaker cables through the passenger side floor.

Wired the remote cable next to the speaker cable - didn't think such a small cable would have any effect one the speaker cables.

Mounted the earth cable to the inside of the boot - where the seats fold down (scraped off paint and tightened very tight with stainless steel bolt.

As I said it works well - enough bass, but annoying that the amp stays on.

Any suggestions? Internal remote switch stuffed?

Hey Mate,

Any pics of where your AMP is installed?
It could be grounding on something.

Also, i would get a new wire and run a new remote wire, but before you go hiding it under the seats and interior just run it over all the interior just for a test to see if it works. Your negative cable should also be the same size as the positive and as short as possible to reduce inteferance. Make sure that where its connected you sand it back a little so it gets good contact.

Let us know how ya go,

Thanks for the response fm_03

No pics, I took the amp back to the shop and they are going to test it/get me a new one. I think it was an amp issue because I tried both ways to switch off the unit (using the remote and antenna wire from the rear of the deck) as well as using the option of turning on/off by sensing power through the speakers without the remote cable installed.

I didn't mount the amp - I just put it on the back seat for testing purposes and wired the ground to the metal directly behind the rear seats (on the side where the moulding fits) I scratched up the panel a bit so the ground was good, and the sub worked very well - no issues.

I will try your suggestions if I have any more issues with the new amp.
