I upgraded in my 1990 300CE, all the factory speakers to MB Quart with a high end Alpine. I bought a 10" sub, closure,
100 watt amp and wires etc. I prefer not to cut the first aid kit out, any other ideas. I have 4 speaker system, 2 in the front and 2 in the rear. My sound dramatically improved when the new Alpine was wired after by passing the factory fader. Prior to this, with the same stereo, the sound was really flat.
Any advice on sibs?
