Yes basically an integrated amp+trunk sub connected through the OEM trunk amp housing. No cut wires. If you’re going to install a trunk sub anyway, this is probably the best option

If you’re lucky enough to have original BMW Sound System wiring it will be plug-n-play to upgrade power and add a trunk sub... well for coupes and sedans with trunk battery locations anyway.

EDIT: I will have two different harness types.. if you're just adding a powered trunk sub it will simply tap into the premium amp wiring directly. Super easy.
