Hi
have 2023 Defender L663 with Meridan audio like many i felt it lacked. Being retired thought it would be a good project .
Did my research but i was not as through as i thought shorted front doors and rears heavy dynamatting and Audison components up front up front.
The speaker adaptors for the 3" mid ranges was a really jigsaw challenge
Now hopefully my last issue can someone give me a pointer as where to take signal for Audison powered sub woofer please

 

I removed the drivers seat for access to the sub and just spliced into the sub wiring for my JBL powered subs input signal..

 

where did you pickup the power for your subwoofer from ?

 

Battery under the passenger seat.

 

Drivers seat on mine
i think it will be easier under the bonnet there is a cover drivers side near jump point
Car is under warranty otherwise theres a nice thick cable to compressor in the boot
