Audio Systems: please help..., 2006 hyundai tiburon, hyundai tiburon

Question
Hello, I have a 2006 Hyundai Tiburon that came factory with 6 speakers and a Kenwood Head unit. I added a Boss Amp and a Motorjoy 12" woofer. It has worked fine for the past month and last Wednesday I hit a pothole driving home from work and all of my factory speakers cut out and the only music coming out is BASS only and thats from my Sub-woofer. Now the only thing that I have done is remove the radio to install the RCA jacks and remote wire for amp, I have no clue what would make the factory speakers stop working when I havent even touched them. Thanks for you help.

Answer
A wire may have fallen off; ground line came loose; there are many possibilities.

If you have the skill, go through all the wiring and check for continuity and tight connections.  All grounds must be to bare metal; check them and tighten them down good.

If you don't have the skill to check the connections, take it to a good independent car install/repair shack and they can do it in a jiffy.
