[QUOTE="aoojf, post: 8678448, member: 677396"] So, I was rocking a pretty cheap kenwood head unit before and everything worked well and had somewhat good bass. Then I bought a Sony MEX-GS820BT head unit and installed it by just unclipping the old one and its harness and putting the new harness + HU in (and the rca cables that run to my alpine subwoofer amp). Everything clipped in with one exception. There was a blue wire (had a name p. cont on one side and ant cont on the other) attached to the old harness that went through some plastic piece and down under the dash somewhere. I just read somewhere it was only needed for some antenna motor or something so I just disconnected the wire so I could get the new HU in. Now I have a clear audio but with no bass. If I crank it up and put all the settings in favor of bass I can hear just a little bit of bass. So, what could be the problem? Hard to imagine polarity being the issue because it worked well before and I only swapped the HU. Or could it be the blue wire or something else? I'm pretty new to car audio so please enlighten me.
