I think it's time that I had my base audio upgraded. I'd like to install some 8" component speaker at the front and tap the speaker lines to install a DSP/class D amplifier. I don't think I want a sub, but we'll see how it goes from there. Would also love to get some sound deadening material in the doors and wheel wells. I'd prefer to take the car to a shop that has plenty of experience with Teslas.
