Sub And Amp Wiring Issue.

[N.Singh]

Currently Own A Audi A3 2007 (57)

Got The Audi Nav Plus System In There Running Stock Speakers, And Had a Wiring Kit Added To It Today.

Managed To Plug My Sub And Amp And Connect It All Up, However No Power To The Amp At All? Whyy?

I Have A JBL7001

Any Suggestions What It Could BE?

Presumably you have connected the remote 12v feed from the HU to the amp?
This is needed to switch the amp on with the HU. The lead should be part of whatever wiring kit you have installed. Not quite sure how you've managed to install a wiring kit on the stock HU and not lose the feed to the rear/sub amp & speakers as they occupy the same connection. Far easier to take the feed from the new sub from the existing stock sub loom as everything you need is already there in the boot. You just need to run power from the battery.
