Old Lanzar amp problem

[skooter]

I have a old lanzar vibe amp and it works and everyting just when you have volume turned up say to 15 on deck, when a bass note hits the amp cuts off and goes into protection mode unlill I turn it, off and back on, then it comes back till the next bass note. on low volume it dosent shut off. and this is with a 4 ohm load.

If the woofer and the wiring are intact and the voltage to the amp isn't dropping significantly, the protection circuit in the amp may be too sensitive or damaged.

lanzar safety feature trips and shuts amp off for no reason...

ok, I have the same problem with my lanzar amp... How could I fix this amp???

Have you confirmed that no speakers are defective?

Have you confirmed, with a multimeter) that the voltage at the power and ground terminals of the amp are not dropping below ~11v?
