Sony Xplod XM-554ZR Car Audio Amplifier going in to power protect mode

Problem with Sony Xplod XM-554ZR Car Audio Amplifier

Wont stop going in to power protect mode

I have a sony XM554ZR amplifier installed in my car. I have checked and double checked the wiring but still it will only go in to power protect mode. Any advice / suggestions are welcome.

I have an amp installed but can not get it to come out of power protect mode. All wiring and fuses have been checked. I have disconnected all RCA and speaker wires and put a multimeter accross the ground / power (14.4 result) and accross the ground / rem (14.25 result) Does this mean that the amp is blown or is there any thing else that I should try?


does it still do it with speaker disconnected?
iuf not then speakers are issue.otherwise amplifier needs to be replaced.

You have to get to the back of the latch and move the release arm. I usually try and get under the vehicle and remove the plastic splash shield from the bottom and get a long screwdriver or something I can fish up from the bottom to that arm to "pop" it open. Here's a couple pictures showing the release arm and latch so you can see where they are located. The release arm (marked B) will release the primary latch.

I have this extra long radiator hose pick that's angled just right to grab it and then I pull down to pop it.  in t...
