wierd amp problem

jamesburkett · 03-08-2008, 12:27 PM

hello all, im new to the forums and had a question regarding my amp, any help or suggestions would be great. So i have a 4 channel soundstream amp hooked up using the interface from the stock deck on my ford explorer. When i turn the power to the battery on (but not the actual truck) power goes to the amp and all works well. When I turn the car on, the amp turns on, recognizes it has power but does not distribute it to the speakers. I have tested this multiple times, everytime i give power to hte battery the amp works flawlessly, but when i turn my car on it fails to produce sound. At first i thought it was a defective amp, but i dont believe that is the case since it consistantly works with power to the battery. Any kind of help would be greatly appreciated, thank you.

What is the power source from battery directly? Also move the turn on lead as it probably is losing voltage after starting up.

try turning the keys to the on position, but dont actually start the truck, that will tell you if its somthing to do with the engine being on or off.

it sounds like when the engine is started, your amp isont getting enough voltage to run properly, you could also try testing it with a multimeter, and seeing if you get enough for the amps rating

your factory stereo is 3 ohm and your amp is either 4 ohms or 8...so..they cant work together. The sound can not be recognized by the amp as it doesnt understand 3ohm. Stop turning it on or you will fry the amp. Good Luck
