Alpine HU - cutting out

[Skuzzle]

I previously had a problem of my h/u cutting out when turned up loud.

I knew it was the earth as I hadn't connected it up (just to start with)

Connected the earth and it solved it.

The problem, however, has come back. Do you think this could be the earth again.

Like I said, it happens the same as before. Only when turned up loud.

Obviously the h/u is earthing slightly through the aerial.

This might be a protection circuit that is activated when the internal amps get to hot.

What speakers are you running off it? Also what model nuber is the unit?

its a cda-7893r

im currently running the standard mk4 hatch speakers with an amped sub setup (2 12's off sony xplod 1000w 2 channel)

Hope that helps

Hmm doesn't sound like it would over heat with that set-up.

Might be best to pop into your local Alpine dealer, and ask for some advice.

i think i'll check my earth out first as i been poking around behind the h/u quite a bit lately.

I presume its wired straight to the battery like it should be, i wouldn't be suprised if its getting a bit hot i know my one did (7876RB but it never cut out) and air flow doesn't happen much behind the astra dash

Yeah I was thinking that, but my Alpine CDA-9815RB hasn't had any problems.
