I have a small Pioneer brick but I don’t recommend it; I found out it is prone to developing a slight hiss and a pop when the amp switches on. However, several brands have the same type of products, they are just a bit more expensive. Something like this: Alpine | KTP-445U
I bought a 2-din conversion and got a shallow 2din touchscreen unit from JVC. Because it’s shallow I have actually been able to fit my amp behind the head unit, I actually used tiewraps to attach it to the 2-din chassis of the head unit
