New to ALP, advice on install Audi S4

[V1Jockey]

Your placement locations look good. If using 2 heads, then 18" - 24" apart. With 3 heads no more than 24" apart, but with your grill that won't be an issue. I have a dual head ALP installed on an Infiniti G37 with the control box and bluetooth module located in the engine bay - no wires through the firewall. I've carefully enclosed the system in a plastic compartment sealed from moisture and heat and so far it works great even in 36C (90F) summer heat. The bluetooth connection is reliable and there's nothing visible inside my car except my phone.
Be very careful that your heads are level and square with each other (not toed in or out).
Good luck.

Thank you the advice. Any thoughts on the placement of the net radar? Do you think it would be OK behind that plastic grill?
