I went back to OEM radio, I was not happy with the Metra dash kit as far as appearance wise. I bought online from e***. It was missing brakets and trim. Plus the dash kit would turnon by it self when the car was off. Other than that it worked fine. I could not get help from Metra to purchase the brakets.
I just installed an AudioControl L6i line converter to OEM radio and it sounds amazing.
It beats PAC one I had before the aftermarket radio. The L6i outputs 9.5 volts, I have it about 3/4 to match the 6 volts input on my amp, I ear the difference compare to a 2-3 volts preamp output from the aftermarket radio. I am able to turn the volume all the way and hear clean undistorted sound.
I have MB Quart four channel amp. The L6i has an auto turn on for external amp.
I am in the process of rewiring the speakers, currently only the rear speakers and 10' Bazooka sub connected.
