Hello Stefan,

Thank you for your great contributions! Your vids/expertise show me the big picture and how the leg bone is connected to the thigh bone.

May I ask...?
From your "garage page," I see you have the BimmerTech One (BT) speakers installed. BUT, you've opted to install the Alpine MRV-500 amplifier (recently?).

I thought I saw an earlier thread of yours where you were leaning towards the BT amp.

Why this Alpine? I'd like to upgrade my stock amplifier (my 2014 335i has the stock hifi system).

May I ask … is it this one?:
Alpine MRV-M500 Mono V-Power Digital Amplifier (1-channel version).

Is this plug and play like the BT amp?

Thanks so much for the wisdom...

Stay healthy and see you on the roads.
