No sound on start-up until I hit a bump.

My 1997 Astro radio has no sound on start-up, but when I drive over a bump in the road the sound comes on and stays on like it was never out. I replaced the radio unit with an aftermarket system, yet the problem persists. I've checked for loose wires, none found. I thought about the amp, but all of the mentions of the amp refer to the rear speakers only. The speakers are either all on or all off, not just the rear.

Any ideas out there? :ty:

You're going to need to trace the vehicle-side harness beginning to end. Somewhere, you have a connector that's loose or a wire that's chafed.
