Hello
I have a 2011 335d
Has the base audio system with no amplifier.
Any way i could wire a factory amp in?
Is there a plug and play option or swap from a car that has an amp?

Thank you in advance!

Yes you can retrofit the factory stuff but it's complicated and aftermarket
stuff will sound much better than anything BMW put's out.
And is also easier to install.

Base system retrofits are one of the most covered topics here.


Do a search for base system upgrades there are many threads.
