Car audio amplifier help needed

[Eric]

Got a wierd problem- the other day I was playing with my audio system
with my new partsexpress woofer and I suddently heard static coming
through the woofer. What da heck! It seems to have come before the
crossover stage cause if I switched on the internal crossover the
static gets filtered. I unplugged the input wire and the static was
still there so its not coming from up above the signal chain. When
the static is going on, it seems to override whatever input is being
fed to the amp as well.

Then, I slapped the amp rather hard with my hand and it went away.
Any ideas whats going on? Its done it more then once. Any ideas?

PS amp in question, Soundstream Rubicon 1002 . Ive had it for a few
years and so far its been solid reliable.

Bad solder connection on the circuit board. Not difficult to repair but can
be a bitch to find sometimes.

Or it could be a leaky electrolytic cap. A little freeze spray may find it.

If slapping the unit fixes it, there is most likely a cold solder
connection. These are sometimes difficult to find, but are fixable if the
tech is experienced, and has the patients to do this type of work.

Or he's got roaches in the car munching on those leftover McDonalds
fries and one is stuck inside the amp and occasionally gets across the
components.
