Hey everyone,

I bought a used Clarion APX400.4 amplifier off a friend. I wired it up and when I try to power it up (turn on the stereo), the power LED just keeps blinking once every maybe 5 seconds and I hear a slight pop in the speakers. I tested the connections with a multimeter and they all appear fine. Any ideas what might be wrong and/or how I can fix it?

Thanks,
Chris

 

Sounds like the amp is going into protection.
Either a speaker is shorting or the amp is fried would be my guess.

 

I called clarion up and they said the load migh tbe messed up. I disconected the highs and just kept the lows connected (which are at 4 ohms). When I started the car the fuse in the amp blew. Any ideas?

Thanks,
Chris
