No Sounds From Speakers When Hit Bump - Head Unit Still On

[nuffsaid]

Hi guys

I have an Alpine touch screen unit with a 4 channel amp for my speakers and a monoblock for the sub.

Lately when I hit a large bump, sometimes even a small bump, I find that no sound comes out from anywhere (speakers or sub), however the head unit is still on and functioning okay.

Probably pretty hard to diagnose online but where can I start looking and what possibilities are there?

Thanks

Have any wires been run under the back seat or anywhere else were they might have been able to wear through from rubbing and vibrations?

Under the back seat is common, people sit on them, they compress and get worn from vibrations ect, then short out when you hit a bump or anyone sits in the back. Try bouncing on the backseat to see if it happens.

Also check the amps earth seeing as the headunit doesn't go out.
