Want to be sure. 10 g coupe with Bose & nav. I see the little amp thing on top of the electronics on the trunk floor.
This is what I am tapping into?
And the wires for my amp, I have HL inputs...
8) Rear Woofer + (SB)(Sky Blue) **Signal from Bose amp
(9) Rear Woofer - (V)(Violet) **Signal from Bose amp
(3) Power/Amp On (GR)(Grey)

Do I keep the connector plugged into the amp? Can I just use the aftermarket sub?
Do I loose anything by not connecting it?

Thanks

 

Correct on the 8/9 woofer hookup and the power on 3.

 

Thanks, should I leave the connecter unplugged?
