I guess I should ask what's the best easily attainable 1.5 din? It appears they've gone extinct, and I want to find a good used one for my GN. Ideally it would be able to control some sort of slave processor, I plan to do a full multi amp system with these custom fiberglass kick pods that came with my car and I'd like to do the tuning from the front seat. Aux input would be a must, usb would be nice but I doubt they were doing that back in the 1.5 din era. Not looking for something too exotic, although it probably sounds like I am, lol. I have a couple different pioneer 1.5 din but wanted to know what other options I had.
