Recently replaced my head unit and bypassed the amplifier. I don't mind shipping. Nothings wrong with it, it worked fine just wanted android auto for my trip across country in a couple weeks.
This is a newer version of what I'm using, a plad 618. It's under $200, and sounds great.
A good set of jbl 6x8 speakers, and a 12" jbl sub fed by an alpine head unit totally kicks ass!
