Protect light comes on, no power
I had a 4 channel amp hooked up in my car. it is an infinity 7540a. i installed it in my new car and everytime i connect the power it flashes the protect light once and then goes dead. i ran the bat + from the fuse box and grounded it properly. do i need to have speakers hooked up for it to work? or inputs? i havent tried hooking anything else up yet, just the power and ground. any ideas? thanks

Hello patrick_h_mi,
You'll also need a remote turn-on source for the amp to operate. Normally, this is a blue or blue/white wire from your head unit, but for test purposes, you just need 12V to the "remote" terminal on the amp. The amp should power up without speaker inputs or speaker connections, but it is not recommended.
Hope this helps.
