Hello suubers,
Can you add a sub? if so, did you need to change the HU?
I obtained the SC subwoofer for the trunk , but no 2nd amp or wiring (like the premium 300 system); I only have the premium 150 non-nav system.

I recently acquired a wheel well sub (pic attatched). We would like to retain the non-nav. HU. I believe the premium 300 added a 2nd amp to drive the sub. Any possibility of making this sub work?

Any input greatly appreciated.
