Subwoofer Installation - Page 2

So even though a stock amp doesn't exist?.. There will still be a white wire that can double as a remote? Like I said, I have found 2 and neither turn on the amp. This is a photo of the cluster of wires on the left of my boot..

And this one is the right hand side of my trunk. As you can see I have the Amp connected to the battery. And is that a suitable location for the ground?

I believe it's solid white, but not 100% sure.
Your best option would be to get a light tester and see which wires work.
First though you should search for a wire diagram/color codes for your model.
All of my wires were on the left side/drivers side (USA) of the trunk.

On both sides of the trunk you should see 2 factory grounds. I connected my amp to the one on the right side of the trunk.
As long as the metal is bare where you connect it you should be good.

if you just want to TEST your amp, your could connect your remote wire directly to any 12V source, to make sure it turns on, but for the actual remote wire, it's a white wire coming off the back of the headunit. That's where i tapped into it, but as it travels along the side of the car to the trunk, you can tap into any where you can find it (some other posters have already mentioned good spots)

We have lift-off. I ended up tapping in to the remote behind the head unit. Rad it under the carpet, backseats and in to the boot. Success! Thanks for all your help!

PROBLEM. The positive wire running from the Amp to Battery cam loose last night. I reconnected it to the amplifier but no green light. Any idea on why this would happen?

Check your fuse.

Fuse is in tact

Did you check the large fuse on your power wire (+12V) for your amp near your battery? Did you check any fuses on the amp itself? If these are ok, then check the remote wire connection and ground wire.
