I recently purchased a cheap Pioneer CD/MP3 player, and after many annoyances at how none of the mounting hardware worked correctly, eventually managed to get both it and my dual amplifiers hooked up and running. However, the second amplifier is having power issues, in that when the car is turned off, it powers on, and when I turn the car off, it powers off. Hmmmm...

As for the setup: I have the 12+ running directly off of the battery, through a small power distributor with an inline fuse. That section seems to be running fine, seeing as the first amp powers on without any problems when I turn the cd player on. I have the amp remote running off the deck's amp remote cable (blue & white) to the first amp, and then another bridged from the first amp to the second amp. I don't think the bridging of the wires is a problem according to the dual amp diagram, and even then, I disconnected the first amp to diagnose the second amp.

Disconnecting the second amp remote power simply doesn't allow the amp to turn on at all. It turns ON when the car is OFF, and OFF when the car is ON. Lol...I thought perhaps the ground and the power were mislabeled on the amp somehow, but switching those around were a big no no, blowing the inline fuse. I checked the grounds and the power, they are both fine, so it seems to be perhaps the amp has finally ended it's run?

Any thoughts?

As for the amps, they are both cheap, the one working without issue is a 500-watt Visontek I got from Pepboy's a few years ago, the other a cheap 250-watt Roadgear.

Screw it. I probably blew the mosfet on the other amp. I just unplugged the remote power lead and put both of them on a toggle switch. It works for now.
