My P.O.'s aftermarket stereo install was a bodge job all the way through. Not only did the cheap head unit look out of place but it was installed so poorly that it just looked wrong. The worst part was that the OEM speaker connector was cut out and the aftermarket amp's output wires spliced in. Who would do such a thing?
How I replaced that bad boy here;
